Toll-like receptors in the pathogenesis of human disease

Abstract

Members of the Toll-like receptor (TLR) family are key regulators of both innate and adaptive immune responses. The function of TLRs in various human diseases has been investigated by comparison of the incidence of disease among people having different polymorphisms in genes that participate in TLR signaling. These studies have shown that TLR function affects several diseases, including sepsis, immunodeficiencies, atherosclerosis and asthma. As this body of data grows, it will provide new insights into disease pathogenesis as well as valuable information on the merits of various therapeutic options.
