Definitions
- the present application relates to compositions and methods for the treatment of respiratory diseases. It also relates to compositions and methods for regulating the paracellular permeability of pulmonary epithelium.
- the compositions and methods of the invention are based in particular on the use of agents or conditions modulating the cytoskeletal tension of pulmonary epithelial cells.
- the invention is useful for the preventive or curative treatment of various pathologies, such as asthma, allergies, obstructive diseases, etc., in mammals, especially humans.
- the pulmonary epithelium is the center of very important exchanges between the external environment and the organism. These exchanges can take place either through the cells of the epithelium or through parallel networks.
- the transport of water or electrolytes, or the absorption of small molecules (molecular weight generally less than about 1000 Da) in the gastric mucosa, intestinal or colonic is carried out transcellularly, through epithelial cells or enterocytes.
- the absorption of large molecules and the passage of toxins or immune cells is mainly paracellular, at the level of "tight junctions", which are arranged between the epithelial cells.
- TJ tight junctions epithelial
- the tight junctions epithelial are structures of connection between the cells bordering the mucous epithelia (digestive tract, lungs). These structures provide and control the transepithelial paracellular transport, from the outside to the submucosa, of various macromolecules (irritants, microorganisms). These structures also allow the migration of immune cells (eg, immunocytes) to the outside.
- Tight junctions are flexible structures consisting of a complex assembly of transmembrane proteins (occludins, claudines) and cytoplasmic proteins (zona ocludens ZO-1, ZO-2, ZO-3 proteins, AF7 proteins, cingulin or 7H6, etc.), variable according to the epithelia considered, which are associated to elements of the cytoskeleton (filaments of myosin, actin, etc.).
- agents disrupting the actin cytoskeleton have been shown to increase the activity of NO synthase in endothelial cells (WO00 / 03746).
- the allergen sensitization process is a very important risk factor in the development of allergies and asthma.
- the mechanisms by which allergens are able to initiate the sensitization phenomenon are not clearly documented in vivo.
- allergens When allergens are inhaled, they come into contact with the pulmonary epithelial wall which prevents their introduction into the body and their contact with the cells of immunity.
- the conditions under which this transfer is possible remain poorly documented in vivo.
- some reports suggest, on in vitro cell cultures, a role of tight junctions in this process, no demonstration has been made of the involvement of these junctions in vivo in the development of sensitization.
- the present application results from the demonstration of an in vivo role of the tight junctions of the pulmonary epithelium in the allergen sensitization process.
- the present application also results from the development of new therapeutic strategies for the treatment of respiratory pathologies, based on a modulation of the para-cellular permeability of the pulmonary epithelium.
- the present application proposes, for the first time, a therapeutic approach to respiratory pathologies based on the use of compounds or conditions for modulating the cytoskeletal tension of pulmonary epithelial cells. This approach makes it possible in particular to control the opening and closing of the tight junctions of the pulmonary epithelium, without necessarily resorting to de novo protein synthesis and / or to significant protein and / or structural degradations at the level of the epithelium.
- This strategy makes it possible to regulate the permeability of the pulmonary epithelium in a specific, fine and reactive manner, and thus to act on the transfer of allergens to the cells of the immunity.
- This strategy is particularly adapted to obtaining a rapid and controllable biological effect over time (reversible).
- the results presented in the application show that substances capable of relaxing the tight epithelial junctions (PAR-2 receptor activating peptide, LPS) promote the alveolar accumulation of neutrophils and eosinophils, as is observed in bronchial diseases. -sulmonary such as asthma.
- results show that a chemical capable of reducing the permeability of the tight junctions of the pulmonary epithelium prevents the accumulation of neutrophils and eosinophils.
- results provide evidence that molecules, agents, conditions or processes that can reduce or suppress the opening of the tight junctions of the pulmonary alveolar or bronchial epithelium are of interest in the treatment of pulmonary diseases, particularly those characterized by intrabronchial and alveolar neutrophils or eosinophils, especially asthma.
- a first object of the invention therefore lies more particularly in the use of a compound modulating the cytoskeletal tension of pulmonary epithelial cells, for the preparation of a medicament intended for the preventive or curative treatment of respiratory pathologies, preferably at least one patient.
- exclusion of hypoxia caused by these conditions in particular excluding hypoxia caused by pulmonary dysfunction.
- pulmonary dysfunction may be caused by emphysema, cigarette smoke, chronic bronchitis, asthma, infectious agents, pneumonitis (infectious or chemical), lupus, rheumatoid arthritis, congenital disorders such as cystic fibrosis, obesity and hereditary deficiency in antitrypsin.
- Hypoxia is defined herein as the decrease below the normal level of oxygen in a tissue.
- Another subject of the invention resides in a method of preventive or curative treatment of respiratory pathologies, comprising the administration to a subject of a effective amount of a compound modulating the cytoskeletal tension of pulmonary epithelial cells.

- the proteins composing the tight junctions are associated with the cytoskeleton of the cells they connect. It is proposed in the context of the invention that the cytoskeletal tension can be modulated in subjects with respiratory diseases or disorders to act in a non-destructive and transient manner on the permeability of their pulmonary epithelium. Thus, the contraction of the cytoskeleton should favor the opening of the tight junctions, while a relaxation of the cytoskeleton (or an inhibition of the contraction) should favor the closing of the junctions.
- Compounds (or conditions) that modulate the contraction of the cytoskeleton of pulmonary epithelial cells are preferably used in the context of the invention, preferably without substantially (substantially) modulating the permeability of the vascular endothelium and / or pulmonary circulatory hemodynamics.

- the compounds are preferred acting directly on the cytoskeletal tension.
- compounds with selective cytoskeletal voltage-selective activity are also preferred, that is, typically compounds that do not directly affect the structure of the tight junction proteins.
- a compound is considered to modulate the cytoskeletal tension as it modulates the opening of tight junctions.
- An inhibitory effect of the contraction does not have to be complete or complete, but it suffices that it diminishes the contraction sufficiently to reduce the opening of the tight junctions corresponding to a minimum decrease of about 30% of the paracellular permeability of the pulmonary epithelium, preferably about 40%, more preferably about 50%.

- Other compounds that inhibit the phosphorylation of the myosin light chain may be used with the exception of
- myosin binding proteins such as, for example, cingulin, or the junction molecules, such as E-cadherin, ⁇ -catenin or desmosomes. Modulation of the activity or expression of these proteins allows regulating the cytoskeletal tension in the context of the present invention.

- proteins of the tight junctions mention may be made in particular of the occludin, claudin, ZO-1, ZO-2, ZO-3, AF7 and 7H6 proteins.
- One means according to the invention of modulating the opening or the closing of the tight junctions resides in the regulation of the synthesis of the binding proteins between the cytoskeleton and the proteins of the tight junctions. By stimulating this synthesis, it is expected a strengthening of the bonds between the tight junctions and the cytoskeleton, leading to a lower permeability of the epithelium.

- FIG. 1 Influence of ML-7 on the increase in paracellular pulmonary permeability of T-labeled human serum albumin induced by intratracheal perfusion of Pseudomonas aeruginosa LPS.
- LPS decreases the levels of radioactivity measured in bronchoalveolar lavage fluids (LBAs) whereas, compared with controls, these levels are significantly higher in the lungs.
- LBAs bronchoalveolar lavage fluids
- This increase in pulmonary permeability is suppressed by pre-treatment of animals with ML7. Indeed, values similar to the control values of radioactivity levels in both LBAs and lungs were measured in these animals.
- FIG. 2 Western blot of phosphorylated forms of the myosin light chain (p-MLC) and the native form (MLC) following the treatment of human bronchial cells NCI-H292 in culture by LPS. Incubation times are indicated on each blot (T corresponding to the control).
- p-MLC myosin light chain
- MLC native form
- the bronchial and alveolar epithelium has epithelial cell binding structures that provide controlled passage of immunocytes through the airways.
- This example shows that certain molecules known for their effect of increasing paracellular permeability at the intestinal level such as SLIGRL promote the intra-alveolar accumulation of immunocytes. (neutrophils, macrophage) and that this effect can be prevented (eg, inhibited, reduced) by oral treatment with taurine.
- ML-7 reduces the intra-alveolar accumulation of immunocytes observed after intratracheal infusion of taurocholate associated with the opening of tight junctions.
- Control sterile water infused 20 min tracheally; 5 mM Taurocholate infused tracheally; ML7 (1 mg / kg / 12 h, 36 h IP) + Taurocholate * p ⁇ 0.001 significantly different from control values

- Example 4 Inhibition by ML7 of the increase in pulmonary permeability induced by Pseudomonas aeruginosa LPS in rats.
- ML7 Myosin Light Chain Kinase Inhibitor, MLCK
- LPS Intrcerebral lipopolysaccharide
- Pulmonary permeability was measured using a tracer, 125 I- labeled human serum albumin, which, after intratracheal infusion, is measured in urine, plasma, lung tissue and bronchoalveolar lavage.
- this example shows that Pseudomonas aeruginosa LPS increases the paracellular permeability at the pulmonary level favoring the accumulation of immunocytes at the pulmonary level and that this effect can be prevented by a treatment involving an MLCK blocker.
- Example 5 ML-7 Reduction of Pseudomonas aeruginosa LPS-induced Bronchial Inflammatory Response in Rats
- This example complements the previous example and illustrates the reduction, by the ML7, of the bronchial inflammatory response induced by Pseudomonas Aeruginosa LPS administered by intra-tracheal perfusion.
- ML-7 thus reduces the intra-alveolar accumulation of immunocytes.

- the cells are then rinsed with RPMI 1640 without BSA and exposed to LPS (2 ⁇ g / ml) or to physiological saline as a control (0.9% NaCl) for periods ranging from 30 minutes to 24 hours.
- Proteins from the NCI-H292 cells exposed to LPS were separated by SDS-PAGE in a 15% polyacrylamide gel and electrophoretically transferred onto nitrocellulose membrane in 25 mM Tris-amino, 192 mM glycine and 20% methanol.
- Immunoprecipitation was performed with a 1/500 diluted human phosphorylated goat anti-myosin antibody (Santa Cruz Biotechnology Inc.) or a human anti-myosin mouse monoclonal antibody (light chains 20K, Sigma-Aldrich, Inc. ) diluted 1/1000, for the detection of p-MLC and MLC-20, respectively.
- Recombinant peroxidase-Protein G was used at 1/1000 dilution as a secondary antibody.
- the immunolabeled bands were revealed by fluorography with ECL reagent (Enhanced Chemiluminescence, Pierce, Perbio Science, Inc.).
- In vitro screening of pharmaceutical formulations can be an effective and cost-effective method for identifying the lead candidate prior to in vivo testing.
- the cells produce tight junctions that inhibit the passage of low molecular weight solution substances and electrical current flow, allowing the use of trans-epithelial resistance (RTE) as a permeability correlate.
- RTE trans-epithelial resistance
- Pseudomonas aeriginosa LPS decreases the electrical resistance in a dose-dependent manner.
- the data obtained corresponding to the maximum dose inducing a response with the maximum decrease of the TEN is considered as the 100% response and is reported for the test compounds.
