Neuroproteasomes Control Tau Filaments by APOE, Age. A groundbreaking new study shines a spotlight on the elusive molecular pathways underpinning Alzheimer’s disease (AD), uncovering a neuron-specific mechanism that orchestrates the formation of tau protein aggregates – a hallmark of neurodegeneration. For decades, researchers have sought to understand how soluble tau proteins transition into the pathogenic paired helical filaments (PHFs) characteristic of AD, but the cellular triggers remained undefined. Now, a team led by Paradise et al. reveals the critical role of a specialized plasma membrane proteasome, termed the “neuroproteasome,” in regulating this pathological tau transformation. Their findings not only demystify a vital cellular process but also link genetic and aging factors to disease progression, with profound implications f...
