When various pathogens invade a host, toll-like receptors (TLRs) play a significant role in recognizing the pathogen-associated molecular patterns carried by the pathogens to induce innate immune reaction, followed by acquired immunity reaction. TLRs have two downstream signaling pathways, the m...
