Abstract

Imatinib mesylate is a selective protein tyrosine kinase inhibitor, which can inhibit BCR/Abl, PDGF-R, c-KIT, c-fms, TCR/Abl, Lck, FLT-3 and MAPKs activities on various cell types. On immune system, imatinib has antiproliferative activity and immunomodulatory effects in lymphocytes, macrophages, mast cells and dendritic cells with abrogating multiple signal transduction pathways involved in pathogenesis of autoimmune diseases e.g. inhibiting IFN-γ, TNF-α, IL-1β and IL-17 pro-inflammatory cytokines and MMPs secretion. To date, the efficacy of imatinib in numerous animal model of autoimmune diseases (rheumatoid arthritis, multiple sclerosis, autoimmune diabetes and glomerulonephritis) has been demonstrated, but application of this drug in human autoimmune diseases should be tested in future clinical trials. This review provides an update on the use of tyrosine kinase inhibitor imatinib mesylate in treatment of autoimmune diseases and its related recent patents that could be developed as a novel and available therapy for the management of the autoimmunity improvement.
