How does APOE4's beneficial immune function reconcile with its established role as the strongest AD risk factor?

PARTIALLY ADDRESSED

This study shows APOE4 carriers have enhanced beneficial innate immune responses, directly contradicting the established view of APOE4 as purely detrimental in neurodegeneration. This paradox challenges fundamental assumptions about APOE4's role in AD pathogenesis. Gap type: contradiction Source paper: APOE genotype-specific differences in the innate immune response (2021, JAMA Neurology, PMID:33432245)
