Methods and compositions for the treatment of immune disorders
View Patent ↗The present invention provides a method of treating an immune-related disorder in a subject, comprising administering to the subject an effective amount of an inhibitor of plexin-A4 activity, which results in reducing the plexin-A4 activity in the subject, and thereby treating the immune-related disorder. Inhibitors of plexin-A4 activity include, for example, plexin-A4 antibodies and plexin-A4 fusion proteins. The present invention further provides a method of treating an immune-related disorder in a subject, comprising administering to the subject an effective amount of an inhibitor of semaphorin-3A (Sema3A) activity, which results in reducing the Sema3A activity in the subject, thereby treating the immune-related disorder. Inhibitors of Sema3A activity include, for example, Sema3A antibodies and Sema3A fusion proteins.
1. A method of treating an inflammatory disorder in a subject, comprising administering to the subject an effective amount of an inhibitor of plexin-A4 activity, wherein the inhibitor of plexin-A4 activity is an inhibitor of semaphorin 3A (Sema3A) activity and is an antibody or active fragment thereof directed to Sema3A and the inflammatory disorder is sepsis, whereby the plexin-A4 activity in said subject is reduced, thereby treating the inflammatory disorder.
2. The method of claim 1 , wherein the antibody or active fragment thereof directed to Sema3A is a monoclonal antibody or is derived from a monoclonal antibody.
3. The method of claim 1 , wherein the inhibitor is administered subcutaneously, intramuscularly, intraperitoneally, topically, intravenously, and any combination thereof.
