1. Alternative activation of macrophages by IL-4 impairs phagocytosis of pathogens but potentiates microbial- induced signalling and cytokine secretion by Audrey Varin, Subhankar Mukhopadhyay, Georges Herbein, and Siamon Gordon Blood Volume 115(2):353-362 January 14, 2010 ©2010 by American Society of Hematology

3. IL-4 priming of MΦs does not modify SRA and MARCO expression or decrease N meningitidis binding at MΦ surface. Audrey Varin et al. Blood 2010;115:353-362 ©2010 by American Society of Hematology

4. Alternative activation potentiates N meningitidis–induced proinflammatory cytokine secretion via MyD88, independent of SRA and MARCO. (A) WT ThioMΦs were cultivated 48 hours in the presence or absence of IL-4 and incubated for 24 hours with or without N men... Audrey Varin et al.
