Abstract:
Intestinal immunity is an important system for host defense and it is influenced by various factors such as diet and diseases. To elucidate the relationship between intestinal immunity and type 2 diabetes, we analyzed the effects of diabetes on intestinal antibody production and IgA repertoire using high-fat diet-fed mice and genetically diabetic KK-Ay mice model. The antibody level in the small intestine increased only in KK-Ay mice. We also confirmed that the IgA repertoire in both models experienced significant changes when compared to that in control mice, and no shared characteristics were observed between the two diabetic models. Antibody production in the intestine is influenced by stimuli associated with the onset of diabetes, and the types of induced IgA would differ depending on the process of disease onset.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
Diabetes Mellitus: Overview and Type I Subtype
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
