Journal ArticleDOI
Cell-Surface Calreticulin Initiates Clearance of Viable or Apoptotic Cells through trans-Activation of LRP on the Phagocyte
Shyra J. Gardai,Kathleen A. McPhillips,S. Courtney Frasch,William J. Janssen,Anna Starefeldt,Joanne E. Murphy-Ullrich,Donna L. Bratton,Per-Arne Oldenborg,Marek Michalak,Peter M. Henson +9 more
TL;DR: It is demonstrated here that calreticulin acts as a second general recognition ligand by binding and activating LDL-receptor-related protein (LRP) on the engulfing cell, which creates an environment where "don't eat me" signals are rendered inactive and "eat me" signalling signals congregate together and signal for removal.
Journal ArticleDOI
The role of phosphatidylserine in recognition of apoptotic cells by phagocytes.
TL;DR: It is still not clear which receptors mediate PS recognition on apoptotic cells; however, several interesting candidates have been proposed and a novel activity expressed on macrophages stimulated with digestible particles such as β-glucan is proposed.
Journal ArticleDOI
Phosphorylation of Bax Ser184 by Akt regulates its activity and apoptosis in neutrophils
Shyra J. Gardai,David A. Hildeman,Steve K. Frankel,Ben B. Whitlock,S. Courtney Frasch,Niels Borregaard,Philippa Marrack,Donna L. Bratton,Peter M. Henson +8 more
TL;DR: It is suggested that Bax is regulated by phosphorylation of Ser184 in an Akt-dependent manner and thatosphorylation inhibits Bax effects on the mitochondria by maintaining the protein in the cytoplasm, heterodimerized with antiapoptotic Bcl-2 family members.
Journal ArticleDOI
Selective activation and functional significance of p38α mitogen-activated protein kinase in lipopolysaccharide-stimulated neutrophils
Jerry A. Nick,Jerry A. Nick,Natalie J. Avdi,Scott K. Young,Lisa A. Lehman,Patrick P. McDonald,S. Courtney Frasch,Marcella A. Billstrom,Marcella A. Billstrom,Peter M. Henson,Peter M. Henson,Gary L. Johnson,G. Scott Worthen,G. Scott Worthen +13 more
TL;DR: Findings support a pathway by which LPS stimulation of neutrophils results in activation of MKK3, which in turn activates p38alpha MAPk, ultimately regulating adhesion, NF-kappaB activation, enhanced gene expression of TNF-alpha, and regulation of T NF-alpha synthesis.
Journal ArticleDOI
Modulation of macrophage efferocytosis in inflammation.
Darlynn R Korns,S. Courtney Frasch,Ruby Fernandez-Boyanapalli,Peter M. Henson,Donna L. Bratton +4 more
TL;DR: This review summarizes the current knowledge of the multiple factors that modulate macrophage efferocytic ability and highlights emerging therapeutic targets with significant potential for limiting chronic inflammation.
