Abstract: | Highlights? AP-3 is selectively required for optimal MHC-II presentation of phagocytosed antigen ? AP-3-deficient dendritic cells induce impaired CD4+ T cell inflammatory responses ? AP-3 regulates TLR4 delivery to phagosomes and subsequent inflammatory signaling ? AP-3 regulates phagosomal peptide:MHC-II complex delivery to the cell surface |
