WebHowever, whether p300/CBP is involved in regulation of tau secretion and propagation is unknown. METHOD: We investigated the relationship between p300/CBP activity, the autophagy-lysosomal pathway (ALP) and tau secretion in mouse models of tauopathy and in cultured rodent and human neurons. Through a high-through-put compound screen, we ...
