[Coxsackievirus B infection and pathogenesis of type 1 diabetes]
Abstract:
Epidemiological and experimental studies suggest that enteroviruses (EV) and particularly coxsackieviruses B (CVB) are likely to trigger or accelerate the onset of islet autoimmunity and the development of type 1 diabetes (T1D) in genetically susceptible individuals. Several mutually non-exclusive mechanisms have been proposed to explain the involvement of CVB in the pathogenesis of T1D. CVB can infect and persist in the intestine, thymic cells, monocytes/macrophages, ductal cells and pancreatic β-cells, which leads to structural or functional alterations of these cells. A chronic inflammatory response and disruption of tolerance towards β-cells due to CVB infections are able to promote the recruitment and activation of pre-existing autoreactive T-cells and the destruction of β-cells. Vaccine or therapeutic strategies to control EV infections have been developed and open perspectives for the prevention or treatment of T1D.

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,...

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...
