Differential roles of TLR2 and TLR4 in the host response to Gram-negative bacteria: lessons from a lipopolysaccharide-deficient mutant of Neisseria meningitidis.

Abstract excerpt

The inflammatory response to bacterial infections plays an important role in the detection and elimination of invading micro-organisms. Various components of the bacterial cell wall are capable of activating this pro-inflammatory response. In the case of Gram-negative bacteria, lipopolysaccharide (LPS) is the dominant trigger, although other bacterial factors are also capable of activating this systemic...
