Abstract: Toll-like receptors (TLRs), as pattern recognition receptors, can not only recognize body's specific ligands and start signal transduction through a variety of signaling pathways (mediated by myeloid differentiation protein 88 or by the TLR domain protein of beta-interferon), which leads to specific immune responses, but also play important regulatory roles in some immune responses caused by mycoplasma, viruses, bacteria and other pathogens. Toll-like receptor family has become research hotspots in recent years because of its important immune regulations, which has important scientific significance and application prospect for the breeding of livestock and poultry. The types, functions, heritable variation and mediated signaling pathways of pig Toll-like receptor family were reviewed in this article, and the application of pig TLRs in disease resistance breeding was introduced intensively, which aimed to provide reference and basis for the research of gene function of pig Toll-like receptor family and screening effective genetic markers.

Key words: pig, Toll-like receptor, immune response, resistance breeding
