Comparing 2 hypotheses side-by-side
Perinatal immune activation induces mTOR-dependent glycolytic reprogramming through sustained HIF1α pathway activation, establishing an augmented glycolytic capacity in microglia. HIF1α drives glycolysis in pro-inflammatory macrophages (pmid:20876827), and trained immunity in monocytes is mTOR-dependent (pmid:28473586), providing mechanistic support for metabolic reprogramming in innate immune cells. Microglia display metabolic shifts in AD models (pmid:30550802), suggesting microglial involveme
Perinatal cytokines, particularly IL-6, may induce lasting CpG methylation at the CX3CR1 promoter through mechanisms including altered DNA methyltransferase activity (PMID:22580505). This could reduce microglial CX3CR1 expression, disrupting fractalkine signaling, impairing surveillance, and potentially removing the neuronal 'off signal,' leading to chronic neurotoxic microglial phenotypes in aging. Supporting this, CX3CR1 deficiency in mice worsens excitotoxicity and Alzheimer disease-related p
