Clearance of apoptotic corpses

Fullard, John F., Kale, Abhijit, Baker, Nicholas E.·2009·Apoptosis

Abstract

Apoptotic corpses can be engulfed and cleared by many other cell types in addition to 'professional' phagocytes such as macrophage. Studies of several organisms have contributed to the understanding of apoptotic corpse engulfment. Two partially redundant engulfment pathways have been characterized that act even in non-professional phagocytes to promote corpse engulfment. This review summarizes some recent progress in signaling by these pathways, including the exposure of eat-me-signals on apoptotic cells, and insights from Drosophila on the roles of the bridging receptor Six Microns Under, the non-receptor tyrosine kinase Shark, and store-operated calcium release in the Draper/Ced-1 pathway of corpse recognition and internalization. The mechanism of apoptotic phagosome maturation is outlined, and possible connections between corpse engulfment and proliferation, cell competition, and immunity are discussed.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Apoptotic cells release 'find me' and expose 'eat me' signals such as PS, lysoPS, cardiolipin, calreticulin, CD31, fractalkine, and small amounts of nucleotides, which are recognized by phagocytes promoting efferocytosis.

    “Apoptotic cells release ‘find me’ and expose ‘eat me’ signals such as PS, lysoPS, cardiolipin, calreticulin, and CD31, as well as the chemokine fractalkine (CX3CL1 as recognized by CX3CR1) and small amounts of nucleotides (ATP, UTP). These ligands are recognized by phagocytes promoting efferocytosis (131, 132).”

  • Both signaling pathways governing apoptotic cell removal converge in activation of Rho GTPases such as Rac1 to promote actin polymerization, membrane ruffling, and phagocytosis.

    “Both pathways finally converge in the activation of Rho GTPases such as Rac1 to promote actin polymerization, membrane ruffling, and phagocytosis (131, 132).”

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.
