Studies were conducted to evaluate the effect of a brief voluntary exercise period on the expression pattern and post-translational modification of multiple protein classes in the rat hippocampus using proteomics. An analysis of 80 protein spots of relative high abundance on two-dimensional gels revealed that approximately 90% of the proteins identified were associated with energy metabolism an...

Objective(s):Hyperglycemia worsens the neuronal death induced by cerebral ischemia. Previous studies demonstrated that diabetic hyperglycemia suppressed the expression of heat shock protein 70 and 60 (HSP70 and 60) in the liver. IgG antibody titres against heat shock protein 27 (anti HSP27) were measured to determine whether hyperglycemia exacerbates ischemic brain damage by suppressing the exp...

Heat-shock and infection induce changes in protein expression in C. albicans. To investigate if these alterations induce changes in antigenicity, we have compared the reactivity mediated by IgA antibodies of protein extracts from a strain of C. albicans and the same strain recovered from an infected animal, both at 24 degrees C and 37 degrees C. The antigenic variability was detected mainly in ...
