To investigate toll-like receptor 2 (TLR2) -196 to -174 del, and TLR4 (+896A/G rs4986790 and +1196C/T rs4986791) polymorphisms at risk of chronic gastritis and gastric cancer in a Brazilian population and association of gastric lesions with risk factors such as smoking, alcohol intake and Helicobacter pylori infection.
The host response to H. pylori has been related to genetic polymorphisms that influence both innate and adaptive immune responses.Our aim was to investigate whether the presence of the TLR4 Asp299Gly, TLR4 Thr399Ile and IL-8-251 A/T polymorphisms had any influence in the development of distal GC in a Mexican population.
We investigated the effects of common polymorphisms of TLR4 Asp299Gly, Thr399Ile and CD14 promoter -C159T on the risk of gastric cancer including its subtypes and clinicopathologic features.
