In the case of type 1 gNET, there is also controversy about the role of H. pylori [33, 34] but its association with other types of cancer, specially gastric cancer is strong [7, 22, 24]; Following our hypothesis of a possible cross-reactivity between H. pylori proteins and human proteins associated with type 1 gNET, we found that HSP60 from H. pylori and human share identity and we identified possible antigenic patches. This evidence concerns the gene HSPD1 and gastric cancer.
