These two processes are involved in various human diseases such as cancers. Previously, the laboratory has shown a sequential and specific involvement of autophagic proteins in the autophagic cascade [1,2]. Recent studies have identified the recruitment of autophagic proteins during phagocytosis of apoptotic corpses in the so called LC3-associated phagocy- tosis (LAP) [3]. LAP is a distinct process from autophagy but it relies on some members of autophagy pathway to allow an efficient degradation of the phagocytosed cargo. The objective of this study is to
