title: Immunohistochemical study of neurons containing corticotropin-releasing factor in Alzheimer's disease.
abstract: In the brains of controls and individuals with Alzheimer's disease (AD), antisera to corticotropin-releasing factor (CRF) were used to immunostain neurons and their processes. In AD, we identified abnormal CRF-immunoreactive axons as well as neurites associated with deposits of amyloid in brain regions showing senile plaques. The number of immunoreactive fibers was decreased in individuals with AD. In contrast, CRF immunoreactivity was markedly increased in some neurons located within the paraventricular nucleus (PVN) of the hypothalamus. These findings support previous neurochemical studies indicating that certain CRF systems are affected in AD.
