Abstract: Rheumatoid arthritis not only affects synovial joints but also many other sites including
heart, blood vessels, and skins. It is more common in females than in males. The exact cause of
rheumatoid arthritis is not well established, but the hypothesis reported in the literature is that in
the development stage of the disease, both genetics and environmental factors can play an inciting
role. Along with these factors, the alteration in the normal physiology of enzymatic action acts as a
trigger to develop this condition. Numerous signaling pathways in the pathogenesis of Rheumatoid
Arthritis involve activation of mitogen-activated protein kinase, kinases Janus family, P-38 Mitogen-
Activated Protein Kinase and Nuclear Factor-kappa B. Interleukin-1, is a proinflammatory cytokine
that plays an important role in inflammation in RA. These are also associated with an increase
in neutrophil, macrophage and lymphocytic chemotaxis, mast cell degranulation, activation,
maturation and survival of T-cells and B-cells activated. These signaling pathways also show that
p38α downregulation in myeloid cells exacerbates the severity of symptoms of arthritis. Thus, the
present review carters about the detail of different signaling pathways and their role in rheumatoid
arthritis.
