1001681 Blocking transmission of of cell-associated lilY-i across a cervical epithelial monolayer 1001691 It has been previously shown that commercially available free anti CD 18 or anti-ICAM-1 antibodies block transmission of cell-associated HIV-1 across a cervical epithelial monolayer (US 6,566,095 and US 20090317404, which are herein incorporated by reference in their entirety). Anti-ICAM-1 (clone MT-M5), anti-CD 18 (clone H52), or isotype control mouse IgGl were added to HP/-infected PBMC immediately prior to their addition to the apical chamber of cervical epithelial transwell cultures (US 20090317404). PBMC were allowed to migrate for 24 hours and antibodies remained present for the duration of the assay. It was shown that both anti-ICAM-1 and anti-CD 18 significantly reduced cell migration at all concentrations when tested over a range of 10-100 g!ml when compared to both untreated and isotype controls. However, anti-CD 18 blocked cell migration significantly better than anti-ICAM-1 at all concentrations tested, ftirther reducing the number of cells detected in the basal compartment when compared to blocking by the corresponding concentration of anti-ICAM-1. Further, it was observed that commercially available free antibodies to CD 18 and ICAM-I when mixed at a 50:50 ratio successfully block transmigration of PBMC from infected cultures (US 20090317404). Increased efficacy was also observed at lower concentrations of anti-CD 18 and anti-ICAM-1, in combination, than at higher concentrations of anti-CD 18 and anti-ICAM-1, individually.

EXAMPLES

1001701 Example 1.

1001711 The aggregation-promoting factor (APF) protein of Lactobacillus crispatus was used as a vector molecule to deliver antibody or a fragment thereof APF protein has useftil characteristics such as high secretion level and non-covalent anchoring to the bacterium.

1001721 The integration vector contains the phage A2 integrase gene (A2-int) which catalyses the insertion of vector DNA containing the A2-attP site into an attB site present in the genome of all lactic acid bacteria tested so far.

Subsequent expression of a 3-recombinase catalyses the deletion of non "food grade" DNA (antibiotic resistance gene, E. coli DNA) located between two six sites. The system can generate stable integration without the use of selection markers and as it presents some flexibility with regard to the sequence of the attB site, it can be use for integration of heterologous genes in various lactic acid bacteria.

1001731 Bacterial strains, plasmids and growth conditions. The bacterial strains and plasmids used are listed in Table 1. Escherichia coli DH5a was grown with shaking at 37°C in Luria-Bertani (LB) medium.

FIG. 1 illustrates an amplified PCR fragments used for the construction of the different expression cassettes. The APF proteins can be divided in three domains, N-terminal, C-terminal and a central region which is rich in asparagine, glutamine, threonine and alanine. PCR fragments are designated from 1 to 5 (see material and methods). Fragment 1: The region encoding the promoter region, the signal peptide (33 amino acids) and the 4 amino acid of the N-terminal domain. Fragment 2: The promoter region and the gene encoding the signal peptide (33 amino acids), the whole N-terminal domain (75 amino acid) and the middle region (37 amino acid). Fragment 3: The promoter region and the genes encoding the signal peptide and the whole N-terminal domain. Fragment 4: The gene encoding the C-terminal domain (last 78 amino acids) and the terminator region. Fragment 5: The gene encoding the middle region, the C-terminal domain and the terminator region. The apf gene of L. crispatus M247 encodes a 223 amino acid protein containing a signal peptide (33 amino acids), a N-terminal domain (75 amino acids), a central region rich in asparagine, glutamine, threonine and alanine (37 amino acids) and a C-terminal domain (the last 78 amino acids) (GeneBank AF492458) (Fig. 1). Eleven expression cassettes were generated by fusing a model scFv antibody or a fragment thereof directed against the SAT/TI adhesion of S. mutans with the promoter region and the gene encoding the APF protein of L. crispatus M247. The expression cassettes differ by the APF region encoding gene fragments included (N-terminal domain, central region and C-terminal domain) or by the insertion of the anchored region of the prtP gene for covalent surface binding of the antibody or a fragment thereof.

1001761 Genomic DNA from L. crispatus M247 was purified and used as a template for amplification of five DNA fragments, ito 5, corresponding to different regions of the apf gene (Fig. 1). The sequences of the primers used for amplification are shown in Table 4.

1001791 Fragments i to 3 were digested with SalT and BarnHI and ligated to a similarly digested pSP72 plasmid, generating psp72SalBamAS, psp72SalBamAS2 and psp72SalBamAS3, respectively. Fragment 4 was cloned between Sad and EcoRI sites in psp72SalBamAS, psp72SalBamAS2 and psp72SalBamAS3 vectors yielding pSP 10, pSP2O, and pSP3 0, respectively. Fragment 5 was also digested with Sad and EcoRI and ligated to similarly digested pSP72Sa1BamAS and pSP72Sa1BamAS3 vectors resulting in pSP4O and pSPSO, respectively.

1001801 The gene encoding a scFv antibody or a fragment thereof directed against the SAT/IT adhesion of S. mutans was amplified from the pLP4O2-scFv-long anchor vector using the primers scFvS and E-tagAS, thus introducing an E-tag gene downstream of the scFv and a NotI restriction site between the scFv and E-tag encoding genes. The PCR product was cloned in pGEM-T vector. The scFv-E-tag gene was further amplified using the primers scFvBgl/Sfi/NcoIS and etagNhe/Sac to introduce the restriction sites BglII, SJII and NcoI upstream the scFv gene and the restriction site NheI and Sad downstream the E-tag gene. The PCR product was digested with BglII and Sad and cloned in pSP1O, pSP2O, pSP3O, pSP4O and pSP5O generating pSP600, pSP700, pSP800, pSP400 and pSPSOO, respectively. The scFv-E-tag gene was also amplified using the primers scFvBgllSfi/NcoIS and etagNhe/Sacstop, introducing a stop codon after the E-tag. The PCR product was digested with Bg/II and Sad and cloned between BamHI and Sad in pSP1O, pSP2O, pSP3O yielding pSP100, pSP200 and pSP300, respectively.

1001811 In order to mediate covalent attachment of the fusion protein to the cell surface, the prtP anchor region encoding gene was amplified from pLP4O1-scFv-long anchor using the primers PrtPNheIS and PrtPSacIAS. The PCR product was inserted between the NheI and Sad sites in psp600, psp700 and psp800 resulting in psp900, pspl000 and pspiiOO. The 11 expression cassettes were subsequently released from the pSP100 to pSP1100 vectors using SalT and EcoRI and ligated into a similarly digested shuffle E. coli/Lactobacillus vector pIAV7 resulting in the pAF plasmid series (pAF 100 to pAF 1100) (Fig. 2). The pAF plasmids were produced in E. coli and then introduced in L. paracasei by electroporation as previously described. FIG. 2 illustrates scFv production by Lactobacilli transformed with plasmids containing different expression cassettes. L. paracasei was transformed with the plasmids pAF 100 to pAF 1100. The scFv production in cell extract (C) and supernatant (S) was analyzed in two separate experiments (1 and 2). For each experiment, all transformants were analyzed at the same time. An equivalent of 125 jil supernatant and extract from 1 x 108 cells was loaded in each well.

1001821 Cloning of scFv antibody or a fragment thereof against human ICAM-1 and YiN fragments against SAt/It adhesion of S. mutans and rotavirus. The scFv anti-ICAM-1 was derived from the mouse monoclonal antibody MTMS. Total RNA was extracted from the monoclonal antibody secreting hybridomas. Variable region encoding sequences of both the heavy (VH) and light (VK) chains were amplified using specific primers with a 5' RACE kit. The VH and VK sequences were fused together with a linker gene encoding the amino acid sequence (G4S)3 and cloned into a pGEM®-T vector after addition of overhang A using Tag DNA polymerase. The scFv anti-human ICAM-1 encoding gene was subsequently amplified using the primers ICAM-NcoI and reverse primers ICAM-NotI. The gene encoding S3 6-VHH directed against the SAT/IT adhesion of S. mutans was amplified from the pURS8SOS36 plasmid using the primers S36NcoI and S36NotI. The gene encoding ARP1 (previously called VHH1) directed against rotavirus was amplified from the pLPSO 1 -ARP 1 plasmid using the primers VHH iNcoT and VHH1NotI. The amplified DNA fragments containing the antibody or a fragment thereof genes were digested with NcoI and NotI and cloned between the NcoI and NotI restriction sites into pAF 100, pAF400 and pAF900 plasmids.

1001831 Chromosomal integration of expression cassettes containing the scFv anti-SAl/Il gene and anti-rotavirus genes. The plasmid pEM 171 was constructed in four steps: i) The 51 9-bp SalI-NcoI fragment of plasmid pAF400, containing the promoter, the signal peptide and the short N-terminal domain of the apf gene, was ligated with pGEM5Z digested with the same enzymes, to generate pEM 157; ii) The 141 5-bp NcoI-BglII fragment, containing the scFv gene and the C-terminal region of the apf gene, was obtained from pAF400 and inserted in pUC2 1 digested with the same enzymes, resulting in pEM1 58. iii) A XbaI (blunt-ended) -Bg/II insert from pEM 158 was cloned into the Ecu 3 611-BamHI sites of the integrative pEM76 vector thus yielding pEM 170. iv) The NdeI-NcoI fragment ofpEMlS7 was inserted into the same sites of pEM17O to yield pEM171.

1001841 Plasmids pEM 181, pEM 182 and pEM23 3 were constructed by interchange of the fragment NcoI-EcoRT of plasmid pEM 171 by the corresponding fragments of pAF900, pAF 100, and pAF900-ARP 1, respectively.

1001851 The integrative plasmids pEM 171, pEM 181, pEM 182, and pEM23 3 were independently introduced by electroporation into L. paracasei. Resulting strains were subsequently electro-transformed with pEM94, a replicative plasmid that carries the 3-recombinase gene, in order to delete, by site-specific recombination, the non-food-grade DNA present in the integrated plasmids. After this depuration step, the strains were cultured at 37°C to eliminate pEM94 (which carries a temperature sensitive origin of replication). The obtained strains were designated L. paracasei EM 171 (secreted and attached scFv), L. paracasei EM 181 (anchored scFv), L. paracczsei EM 182 (secreted scFv), and L. paracasei EM233 (anchored VHH1) respectively. Each step (integration, depuration, and curation) was confirmed by PCR analysis and by Southern blotting.

1001861 Western Blot. Expression levels of scFv produced by the different Lactobacillus transformants were determined by Western Blot. The transformants were grown in MRS medium containing erythromycin (3 jig/ml) until 0D600 0.8. Non-transformed L. paracasei were used as a negative control and grown in MRS only. The cultures were centrifuged at 3,200 x g to separate the pellet from the supernatant. The supernatant was filter sterilized, pH adjusted to 7.3-7.6, dialyzed against 10 mM Tris (pH 8.0) and concentrated using Amicon Ultra-4 centrifugal filter units (10 kDa cut off. Millipore, Carrigtwohill, Co. Cork, Ireland). Concentrated supernatant was mixed with 2x Laemmli buffer and boiled for 5 mm. The cell culture pellet was washed twice with PBS, resuspended in 200 jil Laemmli buffer and boiled for 5 mm. The cell extract was centrifuged at 16,000 x g to remove cell debris and the supernatant containing soluble proteins was saved. The supernatant and cell extract was run on a 10% SDS-polyacrylamide gel at 170 volts and the proteins were transferred onto a nitrocellulose membrane. The membrane was blocked with PBS-TM (PBS with 0.05% (v/v) Tween 20 + 5% (w/v) milk powder) and successively incubated with mouse anti-E-tag antibodies (1 g/ml), and HRP (horse radish peroxidase) labelled goat anti-mouse antibodies.

The signal was detected by chemiluminescence using the ECL P1u5TM Western Blotting detection system.

1001871 Treatment with LiC1. Non-transformed Lactobacilli and Lactobacilli containing the plasmid pAF400 and pAF900 (2 x 1 o9 bacteria) were washed three times with PBS and incubated with 10 ml LiC1 SM on a rocking table for 30 mm at 4°C. The cells were pelleted at 8,000 x g and resuspended in 200 jil loading buffer. The samples were run on SDS-PAGE and transferred on nitrocellulose as described above.

1001881 Quantification by densitometry. The amount of scFv in the supernatant and bacterial extract was estimated by Western Blot densitometry using a purified E-tag scFv as a standard. Two-fold dilutions of the standard scFv and dilutions of the supernatant and bacterial extract were loaded on a 10% polyacrylamide gel and Western Blot was performed as described above. The amount of scFv in the extract was calculated using the Gel Doc image analysis system and Quantity One® analysis software.

1001891 Flow cytometry. 50 jil (1 o7 bacteria) of each culture of Lactobacillus transformants grown until OD600 of 0.8 were washed three times in PBS by centriftigation (10,000 x g for 2 mm) before resuspension in 100 jil of PBS.

An equal amount of mouse anti-E-tag antibody diluted 1/100 was added and the samples were incubated on ice for mm. The washing procedure in PBS was repeated and the samples were resuspended in 100 p1 PBS and mixed with 100 jil Cy-2 conjugated goat anti-mouse immunoglobulin (Jackson Immunoresearch Laboratories, West Grove, PA) (final dilution 1/200) and incubated on ice for 30 mm. The Lactobacilli were fixed using 2% paraformaldehyde.

After washing, the samples were resuspended in 1 ml of PBS and analysed in a FACS Calibur machine.

1001901 To ascertain binding to rhesus rotavirus (RRV), Lczctobacilli grown to an OD of 0.8 were incubated with a 10-fold excess of RRV. This was followed by successive incubation with 1:200 dilution of rabbit anti-rotavirus serum (a generous gift from Dr Lennart Svensson, University of Linkoping) and a 1:200 dilution of donkey anti-rabbit PE conjugate antibody. All incubations were performed on ice for 30 mm. The Lactobacilli were fixed using 2% paraformaldehyde. After washing, the samples were resuspended in 1 ml of PBS and analysed in a FACS Calibur machine.

1001911 Fluid based assay. The assay was similarly performed as for the flow cytometry but the anti-E-tag antibody bound to the bacteria was detected with an alkaline phosphatase conjugated rabbit anti-mouse antibody (1/1,000). Following incubation for 30 mm on ice, the bacteria were resuspended in diethanolamine buffer (1 M, pH 10.0) and 100 jil of the bacterial suspension was added in duplicate to an ELISA plate. 100 jil of 2-fold concentrated p-nitrophenyl phosphate (pNPP) (2 mg/ml) was added to the wells. After 30 mm incubation, the absorbance was read at 405 nm in a Varioskan Flash microplate reader.

1001921 Enzyme-linked immunosorbent Assay. 96-well plates were coated with 100 ji1 recombinant human ICAM-1/Fc, SAT/IT antigen (1 jig/ml in PBS) or rotavims overnight at 4°C. After washing with PBS containing 0.05% Tween 20 (PBS-T), dilutions of the supernatant from L. paracasei cultures secreting scFv anti-ICAM-1, ARP1 or S36 as well as bacterial cells of anchored constructs, were added and incubated at room temperature for 2 h. Supernatants and cells from culture of non-transformed L. paracasei were used as negative controls. Plates were washed twice and a mouse anti-E-tag antibody (1/1,000) was added to the wells. After 1 h incubation at room temperature, plates were washed twice and an alkaline phosphatase conjugated rabbit anti-mouse antibody (1/1,000) was added to the plates. Following incubation for 1 h at room temperature, diethanolamine buffer (1 M, pH 10.0) containing 1 mg/ml of pNPP was added to the wells. After 30 mm incubation, the absorbance was read at 405 nm in a Varioskan Flash microplate reader.

1001931 Mouse model of rotavirus infection. Four-day-old BALB/c pups were used for the study. Lactobacilli (108) were administered to pups once daily in a 1 0-jil volume, starting on day -1 and continuing until day 3.

Infections were made orally on day 0 using 2 x io7 ffu RRV (20 diarrhea doses (DDSO)), a dose which causes diarrhea in more than 90% of inoculated animals. Occurrence and severity of diarrhea was recorded daily until day 4. Diarrhea in the pups was assessed on the basis of consistency of feces. Watery diarrhea was given a score of 2, loose stool a score of 1, and no stool or normal stool a score of 0. Severity was defined as the sum of diarrhea scores for each pup during the course of the experiment (severity = L diarrhea score [day 1 + day 2 + day 3 + day 4]) and duration was defined as the total sum of days with diarrhea.

1001941 Statistical analysis. Both severity and duration were analyzed using Kruskal-Wallis and Dunn tests.

1001951 Comparison of production of scFv anti-SAt/It using different expression cassettes. In order to optimize the production of antibody or a fragment thereof in Lactobacilli, eleven different expression cassettes were made using the secretion machinery of the APF protein of L. crispatus M247 and the scFv anti-SAl/Il adhesion of S. mutans. In some of the cassettes, the gene encoding the Proteinase P (prtP) anchored region, which mediates covalent binding to the bacterial surface was fused to the antibody or a fragment thereof. The production of scFv by the modified Lactobacilli was compared by Western Blot in two different experiments (Fig. 2). Lactobacilli containing pAF 100 and pAF600 show expression only in the supernatant while the other constructs showed expression both in the supernatant and cell extract. L. paracasei pAF400 produced the highest level of scFv in the supernatant while the lowest level was obtained with the Lactobacillus containing pAF300, pAF700 and pAF800.

The amount of scFv produced by L. paracasei transformed with the three plasmids mediating surface anchoring of scFv (pAF900, pAF 1000 and pAF 1100) was shown to be similar. In these constructs, shedding of the fusion proteins into the supernatant was also observed.

1001961 The conserved C-terminal part of APF may mediate non-covalent binding of the protein to the bacterial surface. FIG. 3 illustrates evaluation of display of scFv to the surface of modified L. paracasei. (A), demonstration of non-covalent attachment of scFv to the surface of L. paracasei pAF400 by Western Blot. (i) The bacterial pellet was treated with Lid SM to remove surface proteins and Western Blot of the cell extract was performed. Lane 1: L. paracasei pAF400, untreated pellet; lane 2: L. paracasei pAF400, Lid treated pellet; lane 3: L. paracasei pAF900, untreated pellet; lane 4: L. paracasei pAF900, Lid treated pellet. (ii) Wild type L. paracasei was incubated with the culture supernatant of wild type L. paracasei (lane 5), L. pczracasei pAF 100 (lane 6), and L. paracasei pAF400 (lane 7) to evaluate the binding of scFv. (B) Flow cytometry analysis of Lactobacillus transformants producing surface anchored scFv anti-SAl/Il antibody or a fragment thereof The production of scFv on the surface was shown by detecting the E-tag using a mouse anti-E-tag antibody and Cy-2 conjugated goat anti-mouse immunoglobulin. L. paracasei pAF900 (black line), L. paracasei pAF 1000 (dark grey line), pAF 1100 (light grey line), and non-transformed L. paracczsei (black filled).

1001971 Fusion of scFv to both the middle region and C-terminal part of APF (Lactobacillus pAF400 and Lactobacillus pAF500) results in a higher amount of recombinant protein in the cell fraction. Since the APF was previously shown to be removed from the surface of Lactobacilli by LiC1 treatment, the cell pellet of L. paracasei pAF400 was pretreated with SM LiC1 before protein extraction and Western Blot analysis. Pretreatment of the cell pellet with LiC1 was shown to remove 75% of the scFv fusion protein (55-kDa band) in the cell pellet extract. In comparison, lower amounts of scFv were extracted from the surface of L. paracasei pAF900 (surface anchored scFv) (Fig. 3A). In addition, a 55-kDa band, corresponding to the scFv fusion protein, was observed in the cell extract of non-transformed L. paracasei pre-incubated for two hours with the culture supernatant of L. paracasei pAF400 (Fig. 3A). No band was detected when L. paracasei was previously incubated with the supernatant of L. paracasei pAF 100 or non-transformed Lactobacilli. Although other mechanisms might be involved, these results suggest that the scFv can attach to the cell wall through the middle region and C-terminal part of the APF protein.

1001981 Surface expression of scFv by the transformed Lactobacilli was also analysed by flow cytometry using an anti-E-tag antibody. A positive signal was obtained with the Lactobacillus transformed with pAF900, pAF 1000 and pAF1 100 which display surface anchored scFv (Fig. 3B). No significant difference was observed in the level of expression between these three constructs. L. paracasei transformed with the plasmids pAF 100 to pAF800 did not show any signal by flow cytometry. Although detected on the surface of L. paracasei pAF400 in Western Blot, the scFv attached on the surface of Lactobacilli can not be protrud sufficiently outside the bacterial surface to be recognised by the anti-E-tag in flow cytometry.

1001991 Quantification of scFv anti-SAl/Il produced by selected expression cassettes. Expression cassettes producing fusion proteins with short APF N-terminals were utilized herein. The three selected plasmids were pAF 100, generating secreted scFv only, pAF400, generating both secreted and cell wall attached scFv and pAF900, generating surface anchored scFv. The amount of scFv in the supernatant of L. paracasei pAF 100 and L. paracasei pAF400 was shown to be 100 ng/ml and 1000 ng/ml, respectively. The amount of scFv present in the cell extract of L. paracasei pAF400 and pAF900 was estimated to be approximately 1000 and 2000 scFv fusion molecules/bacterium.

1002001 Expression of scFv anti-ICAM-1 and VHHs in selected expression cassettes. The plasmids pAF 100, pAF400 and pAF900 were subsequently used for expression of a scFv directed against human ICAM-1 in L. paracasei generating L. paracasei pAF 1 00-ICAM, pAF400-ICAM, and pAF900-ICAM. The same plasmids were also use for expression of VHH antibody or a fragment thereof against SAl/Il (S3 6-VHH) (L. paracasei pAF 100- S36, pAF400-536, pAF900-536) and rotavims (ARP1) (L. paracasei pAF100-ARP1, pAF400-ARP1, pAF900-ARP1). ScFv expression was analysed by immunoblotting supernatant or cell extract of L. paracasei-transformed strains using a mouse monoclonal anti-E-tag antibody. A band of 30 kDa was detected in the supernatant of L. paracasei pAF 1 00-ICAM, which migrated at the expected size of the secreted scFv (Fig. 4A). The supernatant and cell extract of Lactobacilli pAF400-ICAM showed a band of 55 kDa which correspond to the scFv secreted in the supernatant and attached on the surface. The band is larger than the theoretical molecular weight (42 kDa), which could be related to posttranslational modification of the C-terminal part of APF. A 60 kDa-band was detected in the cell extract of the Lactobacilli transformed with pAF900-ICAM corresponding to the surface anchored scFv. For the VHHs against SAl/Il and rotavirus, a protein near the predicted size (16.5 kDa) was detected in the supernatant of L. paracasei pAF 1 00-ARP 1 and pAF 1 0O-S3 6 (Fig. 4A). L. paracasei pAF400-ARP 1 and L. paracasei pAF400-53 6 showed a band of 40 kDa in both the supernatant and the cell extract which is higher than the predicted size of the fusion protein (29 kDa) (as previously observed for the similar scFv fusion). The cell extract of Lactobacilli transformed with pAF900-VHH and pAF900-536 showed a major band at 47 kDa, corresponding to the theoretical molecular weight of the surface anchored VHHs. The additional bands detected in the cell extract are most probably degradation products or antibody or a fragment thereof linked to cell wall residues. FIG. 4 illustrates production of scFv and VHH antibody or a fragment thereof by modified Lactobacilli. (A) Western Blot analysis of Lactobacilli producing scFv anti-ICAM-1, ARP1 anti-rotavirus, and VHH anti-SAl/Il (S36). Lane 1: pAF 100, secreted, supernatant; lane 2: pAF 100, secreted, cell extract; lane 3: pAF400, secreted and attached, supernatant; lane 4: pAF400, secreted and attached, cell extract; lane 5: pAF900, surface anchored, supernatant; lane 6: pAF900, surface anchored, cell extract; lane 7: L. paracasei, supernatant; lane 8: L. paracasei, cell extract. An equivalent of 40 jil supernatant and extract from 3.5 x 1 o7 cells was loaded in each well. (B) Flow cytometry analysis of Lactobacillus transformants producing surface anchored scFv anti-human ICAM-1 and VHH antibody or a fragment thereof. The production of scFv on the surface was shown by detecting the E-tag using a mouse anti-E-tag antibody and Cy-2 conjugated goat anti-mouse immunoglobulin. L. paracasei pAF900-ICAM (grey filled), L. paracasei pAF900-ARP1 (black line), L. paracasei pAF900-S36 (grey line), and non-transformed L. paracasei (black filled).

1002011 The amount of scFv and VHH antibody or a fragment thereof was estimated by densitometry (Table 5). The level of scFv and VHH antibody or a fragment thereof in the supernatant was 7 and 4 times higher respectively, using the pAF400 than the pAF 100 plasmid. In addition, the level of antibody expressed in the supernatant or in the cell extract was 7-10 times higher for VHH than for scFv.

1002031 Flow cytometry showed that the scFv and VHHs fragments frised to the prtP anchored region were displayed on the surface of Lactobacilli transformed with the pAF900 plasmids (Fig. 4B). However, as observed for the scFv anti-SAT/TI, no signal was observed for the Lactobacilli transformed with pAF400 (secreted and attached antibody or a fragment thereof). In order to confirm cell attachment, the cells were treated as for the flow cytometry but detected using an enzyme-substrate reaction and the absorbance was read at 405 nm. In comparison to non-transformed Lactobacilli (0D405 0.249), antibody or a fragment thereof could be detected on the surface of Lactobacilli transformed with pAF400-ICAM (0D405 0.429), pAF400-ARP1 (0D405 0.478) and pAF400-S36 (0D405 1.086). The signal was equivalent to a 30-fold dilution of Lactobacilli expressing the corresponding surface anchored fragment.

1002041 Binding of scFv and Vilil antibody or a fragment thereof in ELISA. FIG. 5 illustrates binding activity of antibody or a fragment thereof to antigens in ELISA. Culture supernatant (A, C, E) or bacterial cells (B, D, F) were added to plates coated with human ICAM-1 (A,B), SAT/IT (C, D) and rotavirus (E, F). The binding activity of scFv and VHH antibody or a fragment thereof produced by Lactobacilli, secreted in the supernatant or expressed on the bacterial surface, was analysed by ELISA (Fig. 5). Binding activity of scFv to recombinant human ICAM-1 was observed using the supernatant of Lactobacilli transformed with pAF 1 00-ICAM and pAF400-ICAM. A 4-fold higher binding activity was observed in the supernatant of L. paracasei pAF400-ICAM than L. paracasei pAF 100-ICAM that correlates with the higher amount of scFv produced by the former (Fig. 5A, Table 3). Whole bacterial cells of L. paracasei pAF900-ICAM (surface anchored scFv) were also shown to bind to human ICAM-1 (Fig. SB).

1002051 VHH fragments produced by Lactobacilli were shown to bind with higher activity than scFv antibody or a fragment thereof. The supernatant of Lactobacilli transformed with pAF1 00-ARP1 and pAF400-ARP1 (Fig. 5C) or whole cells of L. paracasei pAF900-ARP1 (Fig. SD) showed good binding to rotavirus particles in ELISA.

Transformed Lactobacilli producing S36-VHH also showed high binding activity to the SAT/IT antigen (Fig. SE and SF). The supernatant of Lactobacilli transformed with pAF400-ARP1 and pAF400-S36 only showed marginally higher binding activity than Lactobacilli transformed with the corresponding pAF 100 plasmids.

1002061 No binding activity was observed using whole Lactobacilli transformed with pAF400-ICAM, pAF400-S36 and pAF400-ARP1. The latter could be due to that the E-tag is poorly detected when the antibody is attached to the cell through the C-terminal of APF as observed above. However, using BacLightTM Green-stained bacteria in a spectrofluorometric assay, binding to antigen coated plates by Lactobacilli transformed with pAF900 was observed but not with pAF400 plasmids.

1002071 To ascertain binding activity of Lactobacilli producing surface expressed ARP1, transformed Lactobacilli were preincubated with RRV and subsequently with rabbit anti-sera against rotavirus and donkey anti-rabbit PE conjugated antibodies. Lactobacilli producing surface anchored ARP1 were shown to bind to rotavims as detected by flow cytometry.

1002081 Chromosomal integration of the gene encoding the scFv anti-SAl/Il. FIG. 6 illustrates production and binding activity of scFv using plasmid-and chromosomally integrated-based expression system. (A) Production of scFv anti-SAT/IT by Western Blot analysis of supernatant and cell extract. Lane 1: L. paracasei; lane 2: L. paracasei pAF 100, secreted; lane 3: L. paracasei EM 182, secreted; lane 4: L. paracasei pAF400, secreted and attached; lane 5: L. paracasei EM 171, secreted and attached; lane 6: L. pczracasei pAF900, surface anchored; lane 7: L. paracasei EM 181, surface anchored. An equivalent of 125 jil supernatant and extract from 1 x 108 cells was loaded in each well. (B) Flow cytometry analysis of L. paracasei producing surface anchored scFv anti-human SAT/IT using plasmid-(L. paracasei pAF900, black line) and chromosomally-integrated (L. paracasei EM 181, grey line) based expression system. Non-transformed Lactobacilli (black filled). The production of scFv on the surface was shown by detecting the E-tag using a mouse anti-E-tag antibody and Cy-2 conjugated goat anti-mouse immunoglobulin. (C) Binding activity of scFv antibody or a fragment thereof produced by plasmid-and chromosomally integrated-based expression systems to SAT/IT antigen using supernatant and bacterial cell suspension in ELISA. The three selected cassettes fiased to the gene encoding the scFv anti-SAT/IT were integrated into the chromosome of L. paracasei using site-specific integration. scFv expression was analysed by immunoblotting (Fig. 6A) and the amount of scFv produced in the supernatant and cell extract was evaluated by densitometry. When integrated on the chromosome, the amount of scFv in the supernatant of L. paracasei EM1 82 (secreted scFv) and in the cell extract of L. paracasei EM 181 (surface anchored scFv) was about 10-fold lower than when using the corresponding plasmid constmct (respectively 12 ng/ml and 100 molecules/bacteria). A 10-fold decrease in fluorescence intensity was also observed by flow cytometry using an anti-E-tag antibody (Fig. 6B). The amount of scFv detected in the supernatant and cell extract of EM1 71 (secreted and attached scFv) was shown to be only 2-fold lower (450 ng/ml and 450 molecules/bacterium) than the plasmid system (1000 ng/ml and 1000 molecules/bacterium).

1002091 Binding activity against SAT/IT antigen was observed using the supernatant and whole bacterial cells in ELISA but at a reduced level than when using the corresponding plasmid system (Fig. 6C). In the supernatant, a 4-fold reduction in binding activity was observed for the secreted and attached scFv (L. paracasei EM 171) and at least, a 8-fold reduction for the secreted scFv (L. paracasei EM 182). Whole bacterial cells of L. paracasei EM 181 were binding at a level less than 16-fold lower than L. paracasei pAF900. No binding activity was observed using whole cells of transformed Lactobacilli producing attached scFv (L. paracasei pAF400 and L. paracasei EM 171).

1002101 Chromosomal integration of the ARP1 anti-rotavirus gene. FIG. 7 illustrates A) Production and binding activity of Lactobacilhi producing surface anchored ARP 1 using plasmid -(L. paracasei pAF900-ARP 1) and chromosomally integrated -(L. paracasei EM23 3) based expression system. (A) Production of ARP 1 by Western Blot analysis of supematant and cell extract. Lane 1: L. paracasei pAF900-ARP1, supernatant; lane 2: L. paracasei pAF900-ARP 1, cell extract; lane 3: L. paracasei EM23 3, supernatant; lane 4: L. paracasei EM23 3, cell extract; lane 5: L. paracasei, supernatant; lane 6: L. paracasei, cell extract. An equivalent of 40 tl supernatant and extract from 3.5 x 1 cells was loaded in each well. (B) Flow cytometiy analysis showing the display of ARP 1 on the surface by detecting the E-tag using a mouse anti-E-tag antibody and Cy-2 conjugated goat anti-mouse immunoglobulin. L. paracasei pAF900-ARP1 (black line), L. paracasei EM233 (grey line), and non-transformed Lactobacihhi (black filled). (C) Binding activity of Lactobacihhi producing surface anchored ARP1 to rotavims measured by flow cytometry. Modified Lactobacihhi were incubated with rotavirus and stained with rabbit anti-rotavirus serum and anti-rabbit PE conjugate antibody. L. paracasei pAF900-ARP1 (black line), L. paracasei EM233 (grey line), non-transformed Lactobacihhi (black filled). (D) Binding activity of modified Lactobacihhi producing surface anchored A1Y1 to rotavirus measured by ELISA. Plates coated with RRV rotavims particles were incubated with serial dilutions of intact bacterial cells. The bound bacteria were detected using a mouse anti-E-tag antibody, an anti-mouse IgG alkaline phosphatase-conjugated and p-nitrophenyl phosphate substrate.

1002111 The cassette mediating surface anchoring ofARP1 was integrated on the chromosome of L. paracasei. In Western blot, the intensity of the bands was 10 times lower with the integrated construct corresponding to 600 molecules/bacteria (Fig. 7A). However, when evaluating the surface display of the ARP1 fragment on the surface of bacteria by flow cytometry using an anti-E-tag antibody, the fluorescence intensity was shown to be only 2.5 lower for L. paracasei EM233 than the corresponding plasmid constmct, L. paracasei pAF900-ARP1 (Fig. 7B).

1002121 L. paracasei EM233 was also grown for 50 generations and fluorescence intensity was evaluated at generation 10, 20, 30, 40 and 50. No difference was observed in the fluorescence intensity between the different generations showing that the integrated gene is stable.

1002131 The binding of whole cells of L. paracasei EM233 to rotavirus was shown to be similar using flow cytometry (Fig. 7C) while using ELISA, whole cells of L. paracasei EM233 was shown to bind to rotavirus particles at a level about 3 times lower than the corresponding plasmid construct (Fig. 7D). Binding to rotavirus was also observed using immunofluorescence microscopy and the intensity was shown to be similar between both constructs (data not shown).

1002141 The transformed Lactobacihhi were administered prophylactically to mice, one day before infection, and the treatment was continued once daily. L. paracasei pAF900-ARP1 and L. paracasei EM233 reduced the duration and severity of diarrhea to a similar level (Table 6).

1002201 A recombinant bacteria (such as a Lactobacilli) will be used to express a functional single chain antibody or fragment thereof against ICAM-1 and/or CD 18 and/or a CD 11 subunit. One or more polynucleotides that encode a functional single chain antibody or fragment thereof against ICAM-1 and/or CD 18 and/or a CD1 1 subunit will be stably integrated into a chromosome of the recombinant bacteria. The recombinant bacteria will be delivered to a human male or female at risk for infection with HW. The recombinant bacteria will be delivered in a pharmaceutical composition to the oral mucosa, urethra, vagina or rectum. The pharmaceutical composition will be in the form of a cream or a gel. The recombinant bacteria will express a functional single chain antibody or fragment thereof against ICAM-1 and/or CD 18 and/or a CD 11 subunit at a level sufficient to inhibit transmission of an HW vims across a vaginal epithelial layer.

1002211 Example 4.

1002221 A population of women at risk for contraction of HIV will be recruited for participation in a protocol that decreases rates of HW infection. The women will be administered one of two pharmaceutical compositions. One pharmaceutical composition will comprise recombinant bacteria (such as a Lactobacilli) that will express a functional single chain antibody or fragment thereof against ICAM-1 and/or CD 18 and/or a CD 11 ("Treatment composition"). One or more polynucleotides that encode a functional single chain antibody or fragment thereof against ICAM-1 and/or CD 18 and/or a CD 11 subunit will be stably integrated into a chromosome of the recombinant bacteria. A second pharmaceutical composition will not comprise the recombinant bacteria ("Placebo composition"). The population of women will be divided into two groups: group One will receive the Treatment composition; and group Two will receive the Placebo composition. Group One will be administered the Treatment composition at intervals sufficient to maintain colonization of their vaginal tracts and/ or rectums with the recombinant bacteria, Group Two will be administered the Placebo composition at the same intervals as group one.

Periodic tissue and or blood samples will be obtained from Groups One and Two to monitor their rate of infection of HIV. The protocol will continue for a length of time sufficient to determine the efficacy of the Treatment composition. At the end of protocol the rate of HP! infection in Group One will be compared to group Two. It is expected that the rate of HIV infection will be lower in Group One than Group Two.

1002241 A population of women at risk for contraction of HIV will be recruited for participation in a protocol that decreases rates of HW infection. The women will be administered one of two pharmaceutical compositions.
