The role of cell adhesion molecules in the inflammatory process and development of gastric and duodenal peptic ulcer disease, their molecular genetic determinants

Abstract

With gastric and duodenal peptic ulcer disease, a chronic inflammatory process develops, in which cell adhesion molecules are actively involved. Currently, as a result of genome-wide association studies (GWAS), more than 20 polymorphic variants involved in determining their level have been identified, including rs505922 of the ABO gene. At the same time, this polymorphic variant, according to GWAS, is associated with an increased risk of developing peptic ulcer disease (PUD). It should also be noted that the association of the O(I) blood group according to the ABO system with an increased risk of developing PUD has long been known. Therefore, the genetic determinants of cell adhesion molecules are of interest for studying as candidate genes for peptic ulcer disease.
