Methods of treating immunological disorders using immunosuppressive compositions
The present disclosure describes a method of treating immunological disorders, for example alloimmune and autoimmune diseases, using a pharmaceutical composition comprising at least one mesenchymal stromal cell-derived protein Further disclosed herein is the use of the pharmaceutical composition for immunomodulation.
1. A method of treating diffuse alveolar haemorrhage, systemic lupus erythematosus (SLE), systemic sclerosis, scleroderma, systemic vasculitis, vasculitis and/or rheumatoid arthritis, the method comprising administration to a subject a pharmaceutical composition consisting of CXCL5 (ENA-78) and one or more pharmaceutically acceptable excipients.
2. The method of claim 1 , wherein the pharmaceutical composition results in a decrease in a concentration of one or more of circulating pro-inflammatory cytokines selected from the group consisting of IFN-γ, IL-6, IL-17A, IL-8, MIP-1β, and MCP-1 in the subject.
3. The method of claim 1 , wherein the pharmaceutical composition results in an increase or a decrease in a concentration of at least one mesenchymal stromal cell-derived protein in the subject, which results in an immunosuppressive effect, wherein the mesenchymal stromal cell-derived protein is selected from the group consisting of PGE2 (prostaglandin E2), OPG, CCL7, CCL8, IL-10, CCL20, CXCL5, CXCL6, M-CSF, IL-1β, CCL-1, and CCL24.
4. A method of modulating the immune system, the method comprising administration of a pharmaceutical composition to a subject, wherein the pharmaceutical composition consists of CXCL5 (ENA-78) and one or more pharmaceutically acceptable excipients.
5. The method of claim 4 , wherein the pharmaceutical composition results in a decrease in a concentration of one or more of circulating pro-inflammatory cytokines selected from the group consisting of IFN-γ, IL-6, IL-17A, IL-8, MIP-1β, and MCP-1 in the subject.
6. The method of claim 4 , wherein the pharmaceutical composition results an increase or a decrease in a concentration of at least one mesenchymal stromal cell-derived protein in a subject, which results in an immunosuppressive effect, wherein the mesenchymal stromal cell-derived protein is selected from the group consisting of PGE2 (prostaglandin E2), OPG, CCL7, CCL8, IL-10, CCL20, CXCL5, CXCL6, M-CSF, IL-1β, CCL-1, and CCL24.
