Fig. 4From: Role of autophagy on cancer immune escapeAutophagy, exosome and immune escape. PD-L1 undergoes endosome and degradation in lysosome, but CMTM6 facilitates endocytosed PD-L1 recycling to membrane. The immune checkpoint protein PD-L1 and CD47 are presented on exosomes, which maybe escape autophagic degradation in lysosomeBack to article page
