Clearance of apoptotic cells by phagocytes

Erwig, L-P, Henson, P M·2008·Cell Death & Differentiation

Abstract

Phagocytic clearance of apoptotic cells may be considered to consist of four distinct steps: accumulation of phagocytes at the site where apoptotic cells are located; recognition of dying cells through a number of bridge molecules and receptors; engulfment by a unique uptake process; and processing of engulfed cells within phagocytes. Here, we will discuss these individual steps that collectively are essential for the effective removal of apoptotic cells. This will illustrate our relative lack of knowledge about the initial attraction signals, the specific mechanisms of engulfment and processing in comparison to the extensive literature on recognition mechanisms. There is now mounting evidence that clearance defects are responsible for chronic inflammatory disease and contribute to autoimmunity. Therefore, a better understanding of all aspects of the clearance process is required before it can truly be manipulated for therapeutic gain.

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

  • Fractalkine CX3CL1 recruits phagocytes and induces MFG-E8, a bridging molecule for detection of apoptotic cells.

    “Another such signal is the fractalkine CX3CL1, which recruits phagocytes 115 and induces one of the bridging molecules for detection of apoptotic cells, MFG-E8 116.”

  • Under homeostatic conditions, macrophages are the prime cells to clear out apoptotic bodies and remnants as well as necrotic material, and these cells are functionally termed efferocytes.

    “Under homeostatic conditions within the body, macrophages are the prime cells to clear out apoptotic bodies and remnants thereof as well as necrotic material. These cells are functionally termed efferocytes (129).”

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.
