The role of TLRs (microbe recognition receptor) in gastric cancer: An update.

Gastric cancer (GC) is the result of a convoluted series of incidents that include host genetic susceptibility, Helicobacter pylori infection, and other external influences. The emergence of many hereditary and chromatin modifications in carcinogenic and tumor-inhibiting genes results in the disruption of several molecular networks, upsetting the balance between cell proliferation and apoptosis as well as the cell cycle. Important roles are played by members of the Toll-like receptor (TLR) family in both native and adaptive immunological reactions.
