Research Abstract

Expression of DEC205, which is antigen uptake receptor on macrophage, was increased in H.pylori infected patients with early gastric cancer. However mRNA of DEC205 was also increased in the patient without gastric cancer. Expression of Th1 cytokines was detected in lymphocyte stimulated with HSP60 from patients with gastric cancer. HSP60 stimulation and its response in T helper CD4 may be available for diagnosis or prediction of gastric cancer caused by H.pylori infection. On the other hand, HSP60 antibody may be associated with cardiovascular disease (CVD) induced by H.pylori infection.
