The purpose of this study was to determine the effect of exercise training alone and in a model of Type 1 Diabetes Mellitus (T1DM), on Heat Shock Protein (HSP) and Nitric Oxide Synthase (NOS) expression in entorhinal adjacent large and small cerebral vessels. Thirty-two rats were randomly allocated to four groups: control sedentary (C), control exercised (CX), diabetic sedentary (D) and diabetic exercised (DX). Exercise training incorporated 5 days/week on a motorized treadmill (27m/min; 6 degree incline; 1 hour) for 10 weeks. Exercise trained groups had significantly greater Hsp70 expression than their respective non-trained groups (p<0.05) and this response was not blunted in T1DM animals. The inducible NOS (iNOS) expression was greater in diabetic sedentary when compared to all other groups (p<0.001). Co-localization of protein with smooth muscle cells illustrates that all HSP and NOS signal content is localized to the smooth muscle area (SMA).
