Age-associated hypermethylation of the Klotho (KL) gene promoter silences this longevity-associated gene in neurons, reducing neuroprotection against oxidative stress and excitotoxicity. A CRISPR-dCas9-TET1-CD fusion system guided to the KL promoter by two gRNAs induces localized 5mC-to-5hmC conversion, reactivating KL expression and enhancing neuronal resilience. DEPRIORITIZED by Domain Expert: locus-specific targeting does not account for distal enhancer elements, boundary elements, or TADs th
**Background and Rationale** TREM2 variants represent major genetic risk factors for Alzheimer's disease, with loss-of-function mutations increasing dementia risk threefold. While TREM2 is exclusively expressed on microglia, emerging evidence suggests its primary pathogenic role occurs through disrupted astrocyte-microglia communication rather than intrinsic microglial dysfunction. Healthy brain homeostasis depends on coordinated responses between these glial populations, where TREM2+ microglia
