Activation of murine macrophages by Neisseria meningitidis and IFN-gamma in vitro: distinct roles of class A scavenger and Toll-like pattern recognition receptors in selective modulation of surface phenotype.

Abstract excerpt

Innate and adaptive immune activation of macrophages (Mphi) by microorganisms and antigen-activated lymphoid cells, respectively, plays an important role in host defense and immunopathology. Antigen-presenting cells express a range of pattern recognition receptors including the class A types I and II scavenger receptors (SR-A) and Toll-like receptors (TLR). Recognition of microbial products by SR-A and TLR...
