Article Abstract
The prevalence of obesity in the United States has continued to increase over the past several decades. A growing concern is that transgenerational effects of obesity negatively impact physiologic functions. We showed that consumption of a high fat, high sugar "Western" diet (WD) decreased the density of both gut innate (Paneth cells) and adaptive immune cells (intraepithelial lymphocytes; IEL). We asked whether consumption of WD impacts gut mucosal immunity in the offspring. WD-mediated Paneth cell loss was reversible, whereas IEL loss was not. However, the overall composition of the fecal microbiome and response to infection were defined by the diet consumed by the progeny. Therefore, offspring from obese dams can prevent gut immunity impairment by consuming a healthy diet.

Enterotoxigenic Escherichia coli (ETEC) is a prevalent intestinal pathogen that significantly impacts both human and animal health. G83, isolated from giant panda feces, has demonstrated notable probiotic properties. In this study, C57BL/6 J mice were randomly divided into Control, ETEC, and G83 groups.

Host-pathogen interactions involve two critical strategies: resistance, whereby hosts clear invading microbes, and tolerance, whereby hosts carry high pathogen burden asymptomatically. Here, we investigate mechanisms by which Salmonella-superspreader (SSP) hosts maintain an asymptomatic state during chronic infection. We found that regulatory T cells (Tregs) are essential for this disease-tolerant state, limiting intestinal immunopathology and enabling SSP hosts to thrive, while facilitating Salmonella transmission.

Constipation is a common gastrointestinal disorder characterized by infrequent and difficult bowel movements, hard stool consistency, and delayed intestinal transit. The present study evaluated the phytochemical profile and physiological effects of the aqueous extract of beetroot leaves (AEBL) in a rat model of Loperamide (LOP)-induced constipation. Thirty-six male Wistar rats were randomly assigned to six groups (n = 6): two controls (normal and constipated) and four constipated groups receiving either increasing doses of AEBL (100, 200, or 400 mg/kg, b.

Steroid-refractory gut acute graft-versus-host disease (SR-Gut-aGVHD) is the major cause of nonrelapse death after allogeneic hematopoietic cell transplantation. High numbers of donor-type IL-22+ T cells, IL-22-dependent dysbiosis, and loss of antiinflammatory CX3CR1hi mononuclear phagocytes (MNPs) play critical roles in SR-Gut-aGVHD pathogenesis. CEACAM1 on intestinal epithelial cells (IECs) is proposed to regulate bacterial translocation and subsequent immune responses in the intestine.

Introduction: Although Coeliac disease (CD) current and only treatment is a life-long strict gluten free diet (GFD), some patients suffer from persistent duodenal lesions despite years into the diet. Hence, we aimed to study the effect that the GFD elicits on the mucosal immune infiltrate from these patients.
Method: To that end, duodenal biopsies were collected from non-coeliac controls and CD patients, both at diagnosis and after at least one year into the GFD.
