  • the present invention provides peptide constructs useful for treatment of autoimmune disease, asthma, allergy, and tissue transplantation rejection (including both host-versus- graft and graft-versus-host rejection) , which differ from the above approaches used with antigenic peptide alone.
  • the novel constructs bind in an antigen specific manner and redirect the T cell in the direction of a nondeleterious autoimmune response, primarily from a Thl to a Th2 immune response, but where advantageous, primarily from a Th2 to a Thl immune response.
  • the novel constructs include one peptide component which will bind to T cells associated with autoimmune disease, asthma, allergies or host versus graft or graft versus host rejection while a second peptide component will bind to sites on the T cells which will preclude the normal sequence of events required for cell activation thereby initiating an abortative T cell modulation resulting in cell anergy and apoptosis.
  • novel peptides of this invention include peptide constructs of the following formula (I) :
  • P ⁇ -x-P 2 ( I ) where P ⁇ is a peptide associated with autoimmune disease, allergy or asthma, or tissue transplantation rejection and which will bind to an antigen receptor on a set or subset of T cells;
  • P 2 is an immune response modifying peptide which will (i) cause a directed immune response by said set or subset of T cells to which the peptide P x is attached or (ii) bind to a T cell receptor which will cause said set or subset of T cells to which the peptide P x is attached to initiate, but not complete, an immune response causing said set or subset of T cells to undergo anergy and apoptosis; and x is a direct bond or linker for covalently bonding P j ⁇ and P 2 .
  • the present invention also provides a first method for treating or preventing inappropriate autoimmune response in individuals at risk for autoimmune disease, allergic reactions, asthma or host-graft or graft-host rejection. wherein a pharmacologically effective amount of a peptide construct of formula (I) is administered to the individual to effectively eliminate the set or subset of T cells involved in the autoimmune response .
  • the present invention also provides a second method for modulating an inappropriate autoimmune response in individuals at risk for autoimmune disease, allergic reactions, asthma or host-graft or graft-host rejection, wherein a pharmacologically effective amount of a peptide construct of formula (I) is administered to the individual to redirect the autoimmune response from a Thl to a Th2 immune response, or from a Th2 to a Thl immune response, whereby the inappropriate autoimmune response is modulated to decrease or eliminate the adverse effects associated with the inappropriate autoimmune response.
  • a different approach would be to have a modulation but not with a full sequence of events, the construct binding in an antigen specific manner with the antigenic epitope but the TCBL ligand binding to a site on another molecule associated with certain early events that are early intermediates in the full expression pathway thereby occupying the space and causing an early event in the process of activation (such as Ca ++ flux, activation of various phosphatases, membrane migration events, such as "patching” or “capping", changes in RNA metabolism) but not supporting the complete activation process which can be thought of as culminating by antigen specific non-antibody mediated
  • Cytotoxic T Lymphocyte activity such as killing of infected or tumor cells, DNA synthesis and cell division, and cytokine secretion, namely, without allowing the ultimate tertiary complex of binding events (MHC, antigen TCR and CD4 (or CD8)) necessary for full activation by being out of the normal temporal sequence of events. Perhaps this early binding would be of such strength that it does not disassociate and allow the cell surface rearrangement necessary for the full and normal sequence of modulatory events, such as, proliferation or secretion of late cytokines such as Fas, TNF- ⁇ or iFN- ⁇ and thereby prohibiting events found in an autoimmune disease associated pathway with complete T cell activation.
  • TCR ICAM-1 also known as CD54
  • LFA-1 also known as CDlla/CD18
  • TC and CD4 or CD8
  • such rearrangement is prevented by the close association in a peptide construct using a TCBL from ICAM-1, LFA-3 (aa26-42) , VLWKKQKDKVAE ENSE (SEQ ID NO:4) (L. Osborn, et al, 1995, JEM, 181:429), by either the disparity in the temporal binding or higher strength of binding activity, thereby preventing the rearrangements and other more intimate interactions necessary for activation. Initially these sites are close together but normally rearrangements on the T cell surface occur during the activation process so by preventing this shift activation should not occur.
  • TCBL from CD4 that binds to the TCR and CD3 may be used as the TCBL in the peptide construct of this invention. Its binding to the T cell recognition site will inhibit subsequent events from occurring (MHC II with CD4 or ⁇ -2 with CD8) .
  • Still another approach is a construct which redirects the immune response initiated by the natural autoimmune inducing event from a TH1 to a TH2 response (see, e.g., Lowrie, et al, 1999, Nature, 400:269; R. Tisch, et al, 1999, J. Immunol., 163:1178).
  • a TH2 directed response is one which directs the immune response toward the TH2 direction, thus favoring production of more IL-5, IL-4, TNF- ⁇ -cytokines and antibody isotypes IgGl and IgG3 in mice (or comparables in man) as opposed to Thl, where the immune response favors production of IFN- ⁇ , IL-2, IL-6, IL-12 cytokines and antibody isotypes IgG2a and IgG2b in mice and Cytotoxic T cell activity. It is understood, of course, that a "TH2 directed response" is not intended to imply an exclusively TH2 response, but rather a mixed immune response which is weighted to favor a TH2 profile.
  • a TCBL associated with TH2 responses e.g., peptide G from MHC class II (D. Zimmerman, et al, 1996, Vacc. Res., 5:91, 5:102; K. Rosenthal, et al, 1999, Vaccine) , IL-4 or IL-5 or peptides known to stimulate 11-4 or IL-5 synthesis are used as the TCBL along with the autoimmune inducing peptide (see, e.g., Hammer, et al, Krco, etal, Araga, et al, Ota, et al, Ruiz, et al, Yoon, et al, supra , Dittel, et al, 1999, J.
  • a TCBL such as peptide J DLLKNGERIEKVE (SEQ ID NO: 51) (D. Zimmerman, et al, supra ; K. Rosenthal, et al, supra ) or ones known to stimulate IL-2 or IL-12 synthesis, would be used along with the autoimmune inducing peptide.
  • Yet another approach is to use the peptide construct to not activate the normal immune process but to activate the process leading to apoptosis of the T cell by using as the
  • TCBL a ligand that binds to a site on the T cell whose normal binding and activation leads to apoptosis of the T cell; such as the TNF- receptor of the T cell, in which the TCBL would be the TNF- ⁇ ligand portion.
  • TNF peptides known to activate macrophages are amino acids 70-80 PSTHVLITHTI (SEQ ID NO:5) (W. J. Britton, et al, 1998, I & I, 66:2122) and perhaps the antagonist peptide represented by DFLPHYKNTSLGHRP (SEQ ID NO: 6) of another region (C. Chirinos-Rojas, et al, 1998, J.
  • H4-1-BB Ligand is useful as a treatment for autoimmune disease similar to uses for flt3-L and CD40L; therefore, H4-1BB may also be used as TCBL for inclusion with autoimmune antigens to form the inventive peptide construct.
  • Other such TCBL examples are available from application with Fas and Fas-ligand including the noncleavable Fas-ligand (WO 99/36079A1) .
  • Fas-Ligand or the sequence obtained by reverse engineering technique to determine amino acid (aa) sequence acting as receptor for DEVD-aldehyde or YVAD chloromethylketone, may also be used as the TCBL.
  • IFN- ⁇ and the IFN- ⁇ ligand can also be used as TCBLs in the invention peptide constructs.
  • the antigenic peptide and the peptide for T cell binding may be directly linked together in any order (i.e., N-terminal of one to C-terminal of other or vice versa) or the peptide may be covalently bonded by a spacer or linker molecule.

  • P x is a peptide associated with autoimmune disease, allergy or asthma, or transplantation rejection and which will bind to an antigen receptor on a set or subset of T cells;
  • P 2 is an immune response modifying peptide which will bind to T cells to cause a directed immune response by said set or subset of T cells to which the peptide P 1 is attached or which will bind to a T cell receptor which will cause said set or subset of T cells to which the peptide P ⁇ is attached to initiate, but not complete, an immune response causing said set or subset of T cells to undergo anergy and apoptosis; and x is a direct bond or linker for covalently bonding P x and P 2 .
  • the TCBL portion of the i munomodulatory peptide construct of this invention may comprise a discontinuous epitope composed of two small regions separated by a loop or by a single chain short peptide in place of the loop (D. Shan, et al, 1999, J. Immunol., 162:6589).

  • Bos d2 131 . 14 ⁇ SEQ ID NO : 32
  • Bos d2 131 . 148 YQQLNSERGVPNENIEN (SEQ ID NO:42)
  • YQQLNSERGVPNENIEN SEQ ID NO:42
  • Another approach to a peptide conjugate for treating allergic conditions is achieved with the following peptide conjugate which will initiate recognition and the activation process but without allowing reorientation and, therefore, will cause truncation of the immune response with premature cessation, resulting in cell anergy and apoptosis.
  • peptide constructs useful in the treatment of allergic conditions associated with dust mite antigens are prepared by linking TCBLs, such as LFA-3 or MHC-l ⁇ , with, for example, fecal allergen of mite Derma tophago ides pteronyssimus Der pi and related mites, known to induce an IgE reaction (Lind et al 1988 J. Immunol. 140:4256; Platts-Mills et al 1987 J. Allerg. Clin. Immunol 80:755), but redirected in accordance with this invention. Moreover, since it is known that Der pi and Der p9 trigtger release of GmCSF, IL-6, IL-8, etc. (C.
  • LFA-3 or MHC-l ⁇ would be expected to be of benefit by the activation/truncation mechanism leading to cell anergy and apoptosis as previously described.
  • PLA A2 81 _ 92 (SEQ ID NO: 38) where PLA A2 81 _ 92 (YFVGKMYFNLID (SEQ ID NO:48)) is a bee venom antigen (A. Faith et al 1999 J. Immunol 162:1836) or
  • Immunol. 153:1124 are peptide constructs according to the invention which can be administered to bee allergic persons to protect such treated individuals against allergic reactions resulting from bee stings.
