DAB2 is dysregulated in microglia as amyloid pathology increases, and its knockdown shifts cells away from DAM/TREM2-linked networks toward TNFNF{kappa}B pro-inflammatory programs.
- Why it matters: APOE4 and RELN signaling interact genetically in AD risk, but how this is implemented in human microglia and dementia-risk gene networks is unclear.
- What they did: The study integrated human brain transcriptomics with a Reln-deficient mouse and DAB1/DAB2 knock-down in APOE isogenic iPSC-microglia, then mapped DAB2-linked networks to DAM/LDAM and dementia-risk loci.
- The result: In vivo, RELN-deficiency reduced microglial ramification and increased CD68, and APOE4/E4 microglia showed elevated APOE, reduced DAB1pY232, and blunted DAB2-knockdown responses.
