Innate Immunity Crosstalk with : Pattern Recognition Receptors and Cellular Responses.

is one of the most successful gastric pathogens that has co-existed with human for centuries. is recognized by the host immune system through human pattern recognition receptors (PRRs), such as toll-like receptors (TLRs), C-type lectin like receptors (CLRs), NOD-like receptors (NLRs), and RIG-I-like receptors (RLRs), which activate downstream signaling pathways. Following bacterial recognition, the first responders of the innate immune system, including neutrophils, macrophages, and dendritic cells, eradicate the bacteria through phagocytic and inflammatory reaction. This review provides current understanding of the interaction between the innate arm of host immunity and , by summarizing recognition by PRRs, and the subsequent signaling pathway activation in host innate immune cells.
