Article Title: G3BP1 Maintains Lysosomal Homeostasis to Limit Tau Aggregate Accumulation
doi: 10.1101/2025.08.29.672259
Figure Lengend Snippet: A schematic model illustrating the differences in lysosomal homeostasis between WT and G3BP1 KO cells. In WT cells (upper panels), G3BP1 cooperates with ESCRT and other factors to repair damaged lysosomes and enhance lysosomal activity, thereby promoting the degradation of Tau aggregates and PFFs. In contrast, in G3BP1 KO cells, these functions are impaired, leading to reduced lysosomal activity and the accumulation of Tau aggregates. However, activation of TFEB by the curcumin analog C1 promotes lysosomal biogenesis and suppresses the accumulation of Tau aggregates.
