The proposed hypothesis posits that in senescent microglia of amyotrophic lateral sclerosis (ALS) patients, the Polycomb Repressive Complex 2 (PRC2) catalytic subunit EZH2 deposits trimethylation of histone H3 at lysine 27 (H3K27me3) across the genomic loci of neuroprotective genes BDNF, GRN, TREM2, and MerTk, leading to their transcriptional silencing. According to this model, pharmacologic inhibition of EZH2 would remove the repressive histone mark and restore expression of these protective fa
The hypothesis proposes that loss-of-function mutations in TBK1 contribute to ALS pathogenesis by trapping microglia in a senescent, pro-inflammatory state characterized by the Senescence-Associated Secretory Phenotype (SASP), thereby accelerating disease progression. Supporting evidence includes a 2025 Nat Commun study demonstrating that microglia-specific TBK1 deletion in an ALS/FTD mouse model reproduces an aged-like transcriptional signature with increased inflammatory gene expression.
