We present evidence here that exosomes stimulate aggregation of Aβ1-42 and and hinder uptake of Aβ by major cultured astrocytes and microglia by preventing exosome secretion and identifies nSMase2 as potential medication target in Advertisement by interfering with exosome secretion. 20-fold more than Aβ incubated alone approximately. Addition of rabbit anti-ceramide IgG (Krishnamurthy et al.… Continue reading We present evidence here that exosomes stimulate aggregation of Aβ1-42 and
