Autophagy allows the degradation of cytosolic endogenous and exogenous material in the lysosome. Substrates are engulfed by double-membrane vesicles, coined autophagosomes, which subsequently fuse with lysosomes. Depending on the involvement of specific receptor proteins, autophagy occurs in a selective or...

Monocytes and macrophages are the two major cell types involved in innate immunity. Exosomes act as signaling molecules to regulate cell-to-cell communication by releasing proteins, mRNAs, microRNAs (miRNAs), and long noncoding RNAs (lncRNAs). However, it is still unclear whether monocyte-derived...
