Toll-like receptor pathway evolution in deuterostomes.

ABSTRACT: Animals have evolved an array of pattern-recognition receptor families essential for recognizing conserved molecular motifs characteristic of pathogenic microbes. One such family is the Toll-like receptors (TLRs). On pathogen binding, TLRs initiate specialized cytokine signaling catered to the class of invading pathogen. This signaling is pivotal for activating adaptive immunity in vertebrates, suggesting a close evolutionary relationship between innate and adaptive immune systems. Despite significant advances toward understanding TLR-facilitated immunity in vertebrates, knowledge of TLR pathway evolution in other deuterostomes is limited. By analyzing genomes and transcriptomes across 37 deuterostome taxa, we shed light on the evolution and diversity of TLR pathway signaling elements. Her
