An Aβ42 uptake and degradation via Rg3 requires an activation of caveolin, clathrin and Aβ-degrading enzymes in microglia.
We demonstrated previously that ginsenoside Rg3 enhances the expression of macrophage scavenger receptor class A (SRA) and amyloid β peptide 1-42 (Aβ42) uptake in BV2 cells. In this study, weExpand
