Article Abstract

Intestinal microbiota controls multiple aspects of body homeostasis. The microbiota composition changes easily in response to internal or external factors, which may result in dysbiosis and associated inflammatory reactions. Thus, maintaining the microbiota composition by the host immune system is crucial, and one of the main mechanisms for microbiota control is production of immunoglobulin A (IgA) at mucosal surfaces. The molecular mechanisms regulating the interactions between the immune system and microbiota remain obscure. A panel of hybridoma cell lines was constructed to produce monoclonal IgA antibodies specific to various commensal bacteria present in intestinal microbiota. The panel can be used to further understand the mechanisms whereby the adaptive immune system controls the microbiota composition.

The alleviation by wheat and oat dietary fiber alone or combined of T2DM symptoms in / mice.

Food Funct

January 2025

Academy of National Food and Strategic Reserves Administration, Beijing, China.

The effects of wheat and oat dietary fiber (DF) alone or combined on T2DM remain unclear. In this research, / diabetic mice were fed with diets containing 10% insoluble wheat dietary fiber (WDF), 10% insoluble oat dietary fiber (ODF), and 10% WODF (mixture of WDF and ODF, WDF : ODF = 1 : 1) for 8 weeks. The results showed that WDF, ODF, and WODF all reduced the body weight and fasting blood glucose (FBG) and improved oral glucose tolerance in / mice.

Introduction: The current understanding of colorectal carcinogenesis is based on the adenoma-carcinoma sequence, where genetics, intestinal microbiota changes and local immunity shifts seem to play the key roles. Despite the emerging evidence of dysbiotic intestinal state and immune-cell infiltration changes in patients with colorectal adenocarcinoma, early and advanced adenoma as precursors of colorectal cancer, and carcinoma as the following progression, are rather less studied. The newly colon-site adapted AI-based analysis of immune infiltrates is able to predict long-term outcomes of colon carcinoma.

Equine pastern dermatitis (EPD) is a multifactorial disease with a change in the skin microbiome. The present study monitored the influence of Biocenol™ 4/8 D37 CCM 9015 stabilized on alginite on the skin microbiota of healthy horses and model patients with EPD. Based on clinical signs, EPD lesions were identified as exudative or proliferative forms.

The pathogenesis of Crohn's disease (CD) remains unknown. The current working theory is that genetic susceptibility influences host-microbe interactions, resulting in chronic inflammation. Case-control studies fail to explain the triggers or pathogenesis of the disease, notably due to confounding factors in patients with established disease.
