Research progress of Toll-like receptors and pulmonary infection / 中国医师杂志

Due to the increase of susceptible individual species and drug-resistant pathogens, pulmonary infection is still a global problem that threatens human health. Toll-like receptors (TLR) can identify pathogenic pattern related molecules on the surface of pathogenic microorganisms in innate immunity and initiate innate immune response. It can participate in different anti-infection mechanisms and play an important role in pulmonary infectious diseases caused by different pathogens. In this paper, the research progress of TLR in pulmonary infection at home and abroad in recent years is reviewed.
