Biochem/physiol Actions

PF06650833 has been studied for its use in the treatment of Waldenstrom macroglobulinemia, indicated by overproduction of IgM (immunoglobulin M)-producing lymphoplasmacytic cells.
PF06650833 is an inhibitor of Interleukin-1 receptor associated kinase 4 (IRAK4). IRAK4 kinase is important in innate immunity, involved in initiating signaling from Toll-like receptors and members of th einterleukin-1 receptor family. IRAK4 kinase is an attractive target for the treatment of various diseases associated with deregulated inflammation, such as rheumatoid arthritis, osteoarthritis, inflammatory bowel disease, and systemic lupus erythematosus. PF06650833 has been investigated for treatment of lupus.

Flares of joint inflammation and resistance to currently available biologic therapeutics in rheumatoid arthritis (RA) patients could reflect activation of innate immune mechanisms. Herein, we show that a TLR7 GU-rich endogenous ligand, miR-Let7b, potentiates synovitis by amplifying RA monocyte and
