The Senescence-Associated Epigenetic Phenotype (SEP) is hypothesized to contribute to neurodegeneration, potentially acting as a driver of disease progression. However, recent reappraisals of accelerated aging in neurodegeneration caution that aging signatures may be correlative and conceptually overextended rather than causal drivers (PMID 37887295). In addition, cellular models of aging and senescence exhibit substantial model-dependence, limiting direct inference from a senescence‑associated
## Mechanistic Overview
TREM2-Dependent Astrocyte-Microglia Cross-talk in Neurodegeneration starts from the claim that modulating TREM2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## **Molecular Mechanism and Rationale** The TREM2 (Triggering Receptor Expressed on Myeloid cells 2) signaling cascade represents a critical node in neuroinflammation regulation, with its dysfunction fundamentally altering astrocyte-microgli
