Immunopharmacology Comments
MAP3K8 (a.k.a. TPL2) is the primary regulator of ERK-mediated gene transcription downstream of multiple proinflammatory stimuli [3,6]. Its expression and activation are modulated by a range of inflammatory receptors, including TLRs, TNFR1, IL-1R1 and IL-1R2 [5], and it is able to amplify local inflammation by promoting the production of several proinflammatory cytokines (e.g. TNFα, IL-1β, IL-6 and IL-8) . Tpl2-deficient mice are protected from inflammatory and autoimmune diseases. Pharmacological inhibitors of MAP3K8 are therefore considered to offer potential to disrupt excessive inflammation and reduce the associated tissue damage in human chronic inflammatory and auto-iimmune diseases. Gilead Sciences have an orally bioavailable, selective MAP3K8 inhibitor in clinical development; GS-4875 (structure not disclosed) has been advanced to Phase 2 evaluation for ulcerative colitis (NCT04130919, primary completion date April 2021) [7].
