Immunopharmacology Comments
p38 MAP kinases are ubiquitous, highly conserved enzymes which regulate the production of proinflammatory mediators (such as TNFα and IL-1) in response to inflammatory cytokines or environmental stress [9-10,12,15-16,18]. They are essential for normal immune and inflammatory responses, but are also involved in many other cellular processes such as regulating the cell cycle and cytoskeletal remodelling.

Pharmacological inhibition of p38 MAP kinases reduces inflammatory cytokine synthesis, making these enzymes validated and extensively pursued drug targets for autoimmune and inflammatory diseases, including arthritis and other joint diseases, septic shock, myocardial injury and neuroinflammation. A number of pan-p38 MAP kinase inhibitors and isoform selective inhibitors have been evaluated in clinical trials, although none have yet reached the clinic.
