Abstract:
BACKGROUND: Helicobacter pylori-induced destruction of the gastroduodenal mucosal barrier is initiated with mucosal infiltration of inflammatory cells. Cytokines and chemokines have been suggested to play important roles in the migration and activation of these inflammatory cells into the mucosa. The present study aimed to investigate expression rates of cyto-chemokine mRNAs using gastric mucosal biopsy specimens. METHODS: In 98 patients infected with Helicobacter pylori, mucosal mRNA expression rates of cytokines (IL-1beta, IL-6, and IL-10), C-C chemokines (macrophage inflammatory protein 1alpha [MIP-1alpha], and macrophage inflammatory protein 1beta [MIP-1beta], monocyte chemotactic and activating factor [MCAF], regulated on activation, normal T cell expressed and presumably secreted [RANTES]) and C-X-C chemokines (IL-8 and growth regulated alpha [GRO-alpha]) were examined using reverse transcription polymerase chain reaction (RT-PCR). RESULTS: The expression rates of mRNA for IL-8, GRO-alpha, MIP-1alpha and RANTES were significantly more increased in H. pylori-positive patients than in H. pylori- negative patients. However, the expressions of IL-1beta, IL-6 and IL-10 mRNA were statistically not different between two groups. After eradication of H. pylori, expressions of mRNA for three cytokines (IL-1beta, IL-6 and IL-10), four C-C chemokines (MIP-1alpha, MIP-1beta, MCAF and RANTES) and two C-X-C chemokines (IL-8 and GRO-alpha) were significantly decreased. CONCLUSION: These results suggest that C-X-C chemokines and some C-C chemokines play important roles in H. pylori-associated peptic ulcer diseases.
