Figure 2 Downregulation of ghrelin expression in the stomach during Helicobacter pylori infection.
Epithelial damage and gastritis induced by Helicobacter pylori determine a diminished expression of ghrelin which, in turn, sustains the ongoing T helper (Th) 1 cells response. Down regulation of ghrelin is also followed by a reduced release of Prostaglandin E2 (PGE2) and interleukin (IL)-10 which, together with pro-inflammatory factors as IL-1β, contribute to the detrimental immune response and damage in the stomach. APC: Antigen presenting cell.
