Abstract

Recent evidence has uncovered cross-regulation of mechanisms of cell engulfment by proteins of the autophagy pathway, in what is called LC3-Associated Phagocytosis, or LAP. By LAP, lysosome fusion to phagosomes and the degradation of engulfed extracellular cargo are facilitated by autophagy proteins that lipidate LC3 onto phagosome membranes. Here we discuss the contexts where LAP is known to occur by focusing on potential roles in tumorigenesis, including predicted consequences of LAP inhibition.

  • Once engulfed, entotic cells are often eliminated by a RCD subroutine independent of BCL2 proteins and caspases, but relying at least in part on LC3-associated phagocytosis.

    “Once engulfed, entotic cells are often eliminated by a RCD subroutine that occurs independently of BCL2 proteins and caspases [694, 704], but relies (at least in part) on a specific autophagy-related process commonly known as LC3-associated phagocytosis (LAP) [509, 705, 706].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
