Abstract

Chronic atrophic gastritis (CAG) is a prevalent form of chronic gastritis that presents with chronic inflammation of the gastric mucosa, localised gastric mucosal glandular atrophy and intestinal metaplasia. Despite the existence of diagnostic criteria, effective therapeutic strategies for this condition remain to be developed. The objective of this study was to examine the potential therapeutic benefits of epiberberine in mitigating MNNG-induced CAG and to elucidate the underlying mechanisms. MNNG was employed to establish a CAG mouse model and a GES-1 cell model, and EPI was observed to be efficacious in ameliorating the gastric mucosal injury and inflammatory infiltration induced by MNNG in the CAG model mice, a finding that was subsequently validated in the GES-1 model cells. Bioinformatics analysis indicated that EPI may exert a direct effect on EGFR, thereby regulating the expression of IL-33 and thereby achieving the therapeutic effect of CAG. This hypothesis was also validated by molecular docking prediction, CETSA, and overexpression of EGFR in GES-1 model cells, using EGFR agonists and inhibitors to further demonstrate that EPI may act as an antagonist supplement to EGFR for the treatment of CAG.

期刊介绍: International Immunopharmacology is the primary vehicle for the publication of original research papers pertinent to the overlapping areas of immunology, pharmacology, cytokine biology, immunotherapy, immunopathology and immunotoxicology. Review articles that encompass these subjects are also welcome. The subject material appropriate for submission includes: • Clinical studies employing immunotherapy of any type including the use of: bacterial and chemical agents; thymic hormones, interferon, lymphokines, etc., in transplantation and diseases such as cancer, immunodeficiency, chronic infection and allergic, inflammatory or autoimmune disorders. • Studies on the mechanisms of action of these agents for specific parameters of immune competence as well as the overall clinical state. • Pre-clinical animal studies and in vitro studies on mechanisms of action with immunopotentiators, immunomodulators, immunoadjuvants and other pharmacological agents active on cells participating in immune or allergic responses. • Pharmacological compounds, microbial products and toxicological agents that affect the lymphoid system, and their mechanisms of action. • Agents that activate genes or modify transcription and translation within the immune response. • Substances activated, generated, or released through immunologic or related pathways that are pharmacologically active. • Production, function and regulation of cytokines and their receptors. • Classical pharmacological studies on the effects of chemokines and bioactive factors released during immunological reactions.
