p38 MAPK is a serine/threonine kinase with a classic kinase fold. It is activated by dual phosphorylation of Thr180 and Tyr182 in the activation loop by MAPKKs MKK3, MKK4, and MKK6.
p38 MAPK is activated by cellular stress, cytokines, and growth factors. It regulates inflammation, cell cycle, apoptosis, and differentiation. In the brain, p38 controls cytokine production in microglia, astrocyte function, and neuronal stress responses.
p38 activation drives neuroinflammation in neurodegenerative diseases. In AD, p38 is activated by A-beta and promotes tau phosphorylation, synaptic dysfunction, and neuroinflammation. In PD, p38 contributes to microglial activation and dopaminergic neuron death. p38 inhibitors have shown efficacy in animal models.
p38 inhibitors have been developed for inflammatory diseases. Losmapimod (GW856553) and PH-797804 have been investigated for AD. Challenges include limited brain penetration and peripheral side effects. New brain-penetrant inhibitors are in development.
