Environmental factors in the etiology of type 1 diabetes.
Type 1 diabetes is considered to be an autoimmune disease in which T lymphocytes infiltrate the islets of pancreas and destroy the insulin producing beta cell population. Besides antigen specificity, the quality of immune reactivity against islet cell antigen(s) is an important determinant of the beta cell destruction. Much evidence indicates that the function of the gut immune system is central in the pathogenesis, as the regulation of the gut immune system may be aberrant in type 1 diabetes. The role of virus infections in the pathogenesis of type 1 diabetes has been supported by substantial new evidence suggesting that one virus group, enteroviruses, may trigger the beta-cell damaging process in a considerable proportion of patients. The latest evidence comes from studies indicating the presence of viral genome in diabetic patients and from prospective studies confirming epidemiological risk effect. If this association holds still true in ongoing large-scale studies, intervention trials should be considered to confirm causality. Of the dietary putative etiological factors, cow's milk proteins have received the main attention. Many studies indicate an association between early exposure to dietary cow's milk proteins and an increased risk of type 1 diabetes. The question will be answered by a large scale, prospective, randomized, international intervention trial. Another dietary factor in need of more studies is the deficiency of vitamin D. Among toxins, N-nitroso compounds are the main candidates. An interaction of genetic and environmental factors is important in evaluating the possible role of a certain environmental factor in the etiology of type 1 diabetes.

Enteroviral Infection Inhibits Autophagic Flux via Disruption of the SNARE Complex to Enhance Viral Replication.
Picornaviruses have evolved to hijack host cellular machinery, including the autophagic pathway. However, the mechanisms remain largely unclear. We use coxsackievirus B3 (CVB3) as a model organism to explore the possible role of picornavirus subversion of the autophagic pathway in viral infection. Our in vivo and in vitro experiments demonstrate that CVB3 infection causes a significant, albeit incomplete, inhibition of autophagic flux by limiting the fusion of autophagosomes with lysosomes and/or late endosomes. Furthermore, we show that CVB3 specifically targets SNARE protein SNAP29 and adaptor protein PLEKHM1, two critical proteins known to regulate autophagosome fusion, for cleavage through the catalytic activity of viral proteinase 3C, ultimately impairing the formation of SNARE complexes. Finally, we demonstrate that loss of SNAP29/PLEKHM1 inhibits autophagic flux, resulting in increased viral replication. Collectively, our study reveals a mechanism that supports an emerging model whereby CVB3 hijacks the autophagic machinery to facilitate its own propagation.
