Repression of RIPK1 kinase by INPP5D inhibits expression of diverse proinflammatory mediators and late-onset Alzheimer's disease risk factors

2 weeks 2 days ago
Genome-wide association studies strongly implicate neuroinflammation in late-onset Alzheimer's disease (LOAD). Genetic risk loci for LOAD are enriched for genes expressed in microglia, but the relationship among microglial LOAD risk genes has been unclear. We found that the N-terminal SH2 domain of INPP5D, an important LOAD risk gene, directly interacted with the cell death regulator RIPK1 at p-Y383 to suppress RIPK1 kinase activation. Microglial INPP5D deficiency cell-autonomously promoted...
