The immunoproteasome in Alzheimer's disease: a dual regulator of tau pathology and microglial senescence.
Alzheimer's disease (AD) is characterized by progressive cognitive decline driven by the convergence of tauopathy, impaired proteostasis, and chronic neuroinflammation. Emerging evidence identifies the immunoproteasome (iP), particularly the β5i/LMP7 subunit, as a central regulator linking these pathological processes....
