Abstract

Defects in a form of noncanonical autophagy, known as LC3-associated phagocytosis (LAP), lead to increased inflammatory pathology during fungal infection. Although LAP contributes to fungal degradation, the molecular mechanisms underlying LAP-mediated modulation of inflammation are unknown. We describe a mechanism by which inflammation is regulated during LAP through the death-associated protein kinase 1 (DAPK1). The ATF6/C/EBP-β/DAPK1 axis activated by IFN-γ not only mediates LAP to Aspergillus fumigatus but also concomitantly inhibits Nod-like receptor protein 3 (NLRP3) activation and restrains pathogenic inflammation. In mouse models and patient samples of chronic granulomatous disease, which exhibit defective autophagy and increased inflammasome activity, IFN-γ restores reduced DAPK1 activity and dampens fungal growth. Additionally, in a cohort of hematopoietic stem cell-transplanted patients, a genetic DAPK1 deficiency is associated with increased inflammation and heightened aspergillosis susceptibility. Thus, DAPK1 is a potential drugable player in regulating the inflammatory response during fungal clearance initiated by IFN-γ.

  • The anti-inflammatory activity of IFN-γ in CGD occurs via induction of Ca+2/calmodulin-regulated serine-threonine kinase DAPK1 in macrophages, which subsequently activates LAP parallel with the proteosomal degradation of the NLRP3 inflammasome.

    “Similarly, the anti-inflammatory activity of IFN-γ in CGD occurs via induction of the Ca+2/calmodulin-regulated serine-threonine kinase DAPK1 in macrophages, which subsequently activates LAP parallel with the proteosomal degradation of the NLRP3 inflammasome (259).”

  • Activation of LAP in macrophages also regulates inflammatory signaling pathways.

    “Notably, activation of LAP in macrophages also regulates inflammatory signaling pathways (258, 259).”

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.
