- Eosinophilic gastritis (EoG) is a chronic inflammatory disease characterized by infiltration of eosinophils and mast cells, epithelial remodeling, and fibrosis. Although EoG is increasingly recognized as a distinct type 2 inflammatory disease, the cellular and molecular events that drive disease pathogenesis remain poorly understood. This is due in part to the absence of robust and physiologically relevant experimental models that recapitulate human disease METHODS: Experimental EoG was induced in wild-type and Il13ra1 mice by repeated intragastric oxazolone challenges in skin-sensitized mice. IL-4Rα was neutralized using antibodies. Gastric histopathology was determined by H&E, anti-Ki67, chloroacetate esterase, and anti-MBP staining. Gastric RNA was subjected to RNA sequencing. - Source: PubMed

Dsilva AnishSharma ShraddhaBarakey ShireenWagner ArielKeisar AliceBar-On TaliItan MichalMunitz Ariel - The pathogenesis of gallbladder adenocarcinoma(GBC) remains inadequately elucidated. While its association with intestinal metaplasia (IM) has been acknowledged, there is a paucity of evidence connecting GBC to the most prevalent metaplastic type-pseudopyloric metaplasia (PPM). Given the morphological similarities between PPM and spasmolytic polypeptide-expressing metaplasia (SPEM), a recognized gastric precancerous condition, we propose that trefoil factor 2 (TFF2)-positive PPM may represent a cellular origin of GBC. Furthermore, we examine the role of the emerging therapeutic target claudin-18 (CLDN18) in this context. Through immunohistochemistry (IHC) analysis of 37 GBC, 30 biliary intraepithelial neoplasia (BilIN), 20 intracholecystic papillary neoplasm (ICPN), 26 IM, and 20 PPM samples, we observed an inverse correlation between CLDN18 expression and vascular invasion, whereas TFF2 expression was positively associated with tumor differentiation. CLDN18 overexpression(a staining intensity ≥ 2 + in ≥ 75% of tumour cells) was identified in 18.9% of GBC cases. This study provides the first evidence that CLDN18 is specifically activated at the precursor stage of gallbladder carcinogenesis, being strictly confined to lesions with an intestinal phenotype (IM, BilIN, ICPN) while remaining entirely negative in normal epithelium and PPM. This "all or none" expression pattern establishes CLDN18 as an ideal biomarker for identifying high risk gallbladder precursor lesions, particularly for recognizing PPM that has undergone malignant prone intestinal differentiation. Furthermore, the subset of GBCs with high CLDN18 expression identifies patients who may benefit from CLDN18 targeted therapies. - Source: PubMed

Zhang QingqingWu DiGuo FengyunYang ShengnanBao LijingZhang RuiyingWang Ping - In clinical practice, Hezi Qingyou Formula (HZQYF) has been observed to effectively alleviate clinical symptoms associated with gastri ulcers, though its precise mechanism of action remains unclear. To investigate the effects of HZQYF on gastric ulcers, we established a rat model of gastric ulcer and examined its impact on ulcer area, pathological changes, inflammatory cytokines, gastric repair factors, levels of T-superoxide dismutase (SOD), and malondialdehyde (MDA), as well as metabolites in gastric tissue and feces. The results demonstrated that HZQYF significantly reduced the gastric ulcer area and promoted gastric tissue repair in rats. It downregulated the phosphorylation of P-P38, P-JNK1/2, and ERK1/2 proteins in the mitogen-activated protein kinases (MAPKs) pathway, inhibited pro-inflammatory cytokines such as interleukin (IL)-6, IL-1β, and tumor necrosis factor-α (TNF-α), enhanced the expression of gastric repair factors including vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), trefoil factor family 2 (TFF2), and prostaglandin E2 (PGE2), reduced MDA content, and increased the activity of the antioxidant enzyme T-SOD, thereby suppressing inflammatory responses and ameliorating gastric mucosal damage. Metabolomic studies revealed that HZQYF effectively normalized 40 metabolites in gastric tissue through four key metabolic pathways and 39 metabolites in feces through five key metabolic pathways. Notably, it regulated taurine and hypotaurine metabolism, as well as phenylalanine metabolism, restoring metabolite levels to normal and ameliorating metabolic disorders in diseased rats. In conclusion, HZQYF promotes the healing of experimental gastric ulcers in rats through anti-inflammatory effects, activation of gastric repair factors, and normalization of gastric tissue metabolites, suggesting its potential therapeutic role in the treatment of gastric ulcers. - Source: PubMed
