Compositions and methods for treating inflammatory bowel disease and airway inflammation
Provided are compositions and methods for treating inflammation due to an immune response. Non-limiting example compositions include class-2 SPATE proteins that are capable of cleaving proteins involved in an inflammatory immune response in a patient. Example compositions include at least one mucin-cleaving class-2 SPATE protein. Further example compositions include protein involved in intestinal colonization (Pic). Non-limiting example methods include methods of decreasing inflammation in a patient having inflammation and methods of perturbing immune response in a patient having a disease or condition in which an active immune response is attributable to a cause of the disease or condition, by administering to the patient a composition including at least one class-2 SPATE protein capable of cleaving proteins involved in an inflammatory immune response.
1. A method for treating an inflammatory immune response in a patient having an inflammatory bowel disease selected from the group consisting of Crohn's disease, the method comprising administering to said patient a composition comprising Pic protease, which cleaves proteins involved in an inflammatory immune response, after administration to said patient.
2. A method of perturbing immune response in a patient having an inflammatory bowel disease selected from the group consisting of Crohn's disease, the method comprising administering to a patient having a disease or condition in which an active immune response caused by said disease or condition a composition comprising Pic protease, which cleaves proteins involved in the immune response, after administration to said patient.
3. The method of claim 1 , wherein administering the composition to the patient by at least one method selected from the group consisting of topical, inhalation, intranasal, oral and intravenous administration.
4. A method for decreasing inflammation in a patient having an inflammatory bowel disease selected from the group consisting of Crohn's disease, the method comprising administering to a patient having inflammation a composition comprising Pic protease, which cleaves proteins involved in an inflammatory immune response, after administration to said patient.
5. The method of claim 4 , wherein administering the composition to the patient by at least one method selected from the group consisting of topical, inhalation, intranasal, oral and intravenous administration.
6. The method of claim 4 , wherein said composition comprises an aerosolized composition.
7. The method of claim 4 , wherein said composition is formulated as a topical composition for topical administration to a patient.
8. The method of claim 4 , further comprising administering to the patient at least one additional composition for decreasing inflammation in a patient selected from the group consisting of immunomodulators, antibiotics, biologics.
9. The method of claim 8 , further comprising administering to the patient at least one additional composition for decreasing inflammation in a patient selected from the group consisting of aminosalicyclates, corticosteroids, and probiotics.
10. The method of claim 4 , wherein said administering comprises direct administration of the Pic protease to a site of action.
