| abstractText | The effects of long-term chronic stress (induced by repeated restraint, overcrowding or both), short-term chronic stress (induced by a triad of stressors over a short period of time early in life) and adrenalectomy were investigated on the prevalence, on the degree of insulitis and various physiological and immunological parameters in the NOD mouse, a spontaneous model of type I-insulin-dependent diabetes mellitus (IDDM). Long-term chronic stress, obtained by restraint once a week or overcrowding, significantly protected NOD females, while both applied concomitantly had only a tendency to protect against diabetes. In contrast, short-term chronic stress had no significant effect on diabetes expression, whereas adrenalectomy resulted in a trend toward accelerated diabetes onset. The various long-term chronic stress paradigms exerted different effects on the progression of insulitis: repeated restraint tended to protect against insulitis, overcrowding had no effect but, when associated with restraint, significantly counteracted the beneficial effect of restraint alone. Adrenalectomy and short-term chronic stress had no significant effect on the development of insulitis. Various parameters, such as body, thymus and spleen weights, thymus and spleen cellularities, mitogen-induced spleen cell proliferation and serum corticosterone levels were also studied under the various experimental conditions. Taken together, the observations suggest that stressors modulate the expression of spontaneous autoimmune diabetes by exerting pleiotropic effects on immune and/or inflammatory components at the pancreas level and on peripheral glucose metabolism. |
