Exosomal NEDD4L derived from HG+oxLDL-induced vascular endothelial cells accelerates macrophage M1 polarization and oxLDL uptake by ubiquitinating IκBα and PPARγ

HG+oxLDL-induced HCMECs-derived exosomal NEDD4L could enhance the ubiquitination of IκBα and PPARγ to facilitate macrophage M1 polarization and oxLDL uptake, thus accelerating DM-related AS.
