Toll-like receptors control activation of adaptive immune responses

M Schnare et al. Nat Immunol. 2001 Oct.

Abstract

Mechanisms that control the activation of antigen-specific immune responses in vivo are poorly understood. It has been suggested that the initiation of adaptive immune responses is controlled by innate immune recognition. Mammalian Toll-like receptors play an essential role in innate immunity by recognizing conserved pathogen-associated molecular patterns and initiating the activation of NF-kappaB and other signaling pathways through the adapter protein, MyD88. Here we show that MyD88-deficient mice have a profound defect in the activation of antigen-specific T helper type 1 (TH1) but not TH2 immune responses. These results suggest that distinct pathways of the innate immune system control activation of the two effector arms of adaptive immunity.
