Increased glucocorticoid receptor gene expression in the rat hippocampus following combined serotonergic and medial septal cholinergic lesions.


Glucocorticoid excess is associated with hippocampal neuronal dysfunction and loss, mainly affecting CA1. Degeneration of both cholinergic and serotonergic (5-HT) hippocampal afferents is prominent in aged rats and Alzheimer's disease. Lesions of these individual pathways alter hippocampal expression of mineralocorticoid (MR) and glucocorticoid (GR… (More)
