Abstract
The innate immune system is the primary line of defence against invading pathogenic microbes. Toll like receptors (TLR) are a family of membrane receptors which play a pivotal role in sensing a wide range of invading pathogens including bacteria, fungi and viruses and enable host to recognize a large number of pathogen-associated molecular patterns (PAMP) such as bacterial lipopolysaccharides, viral RNA, CPG-containing DNA, and flagellin, among others. TLR mediate responses to host molecules, including defensin, ROS, HMGB 1 (high-mobility group box protein 1), surfactant protein A, fibrinogen, breakdown products of tissue matrix, eosinophil-derived neurotoxin (EDN) and heat shock proteins (HSP). Dysregulation of TLR signaling is linked with a number of disease conditions. In this review, we focus on the evidence provided to date to explain the role of TLR in host defense against microbial pathogens. The relationship between heat shock proteins (HSP) and Toll-like receptors (TLR) has only just begun to be elucidated. This chapter highlights the role of TLR1-11 in infectious diseases and discusses the emerging role of HSP and TLR in this process.
