Differential involvement of hypothalamic vasopressin neurons in multiple system atrophy.
We sought to determine whether there is differential involvement of different groups of hypothalamic arginine-vasopressin (AVP) synthesizing neurons in multiple system atrophy (MSA). Hypothalamus was obtained from five subjects with clinical diagnosis of MSA confirmed neuropathologically and five age-matched controls. Sections were immunostained for AVP, and cells with visible nuclei were count...
متن کاملThe hypothalamic suprachiasmatic nuclei: circadian patterns of vasopressin secretion and neuronal activity in vitro.
The suprachiasmatic nuclei (SCN) are intrinsic pacemakers which organize circadian rhythms in mammals. When the SCN of Long-Evans rats are surgically isolated and perifused in vitro, they retain the ability to express a 24 hr rhythm of neuronal firing rate. We find that the SCN are also capable of secreting the peptide vasopressin (VP) in a circadian pattern. The pattern of VP secretion is simi...
متن کاملVasopressin regularizes the phasic firing pattern of rat hypothalamic magnocellular vasopressin neurons.
Vasopressin (AVP) magnocellular neurons of hypothalamic nuclei express specific phasic firing (successive periods of activity and silence), which conditions the mode of neurohypophyseal vasopression release. In situations favoring plasmatic secretion of AVP, the hormone is also released at the somatodendritic level, at which it is believed to modulate the activity of AVP neurons. We investigate...
متن کاملVasopressin and oxytocin excite MCH neurons, but not other lateral hypothalamic GABA neurons.
Neurons that synthesize melanin-concentrating hormone (MCH) colocalize GABA, regulate energy homeostasis, modulate water intake, and influence anxiety, stress, and social interaction. Similarly, vasopressin and oxytocin can influence the same behaviors and states, suggesting that these neuropeptides may exert part of their effect by modulating MCH neurons. Using whole cell recording in MCH-gree...
متن کاملIntracerebroventricular injection of senktide-induced Fos expression in vasopressin-containing hypothalamic neurons in the rat.
Intracerebroventricular injection of senktide, a selective agonist for neurokinin B receptor (NK3), induced Fos expression in many neurons of the rat hypothalamus. Fos-positive neurons were predominantly present in the supraoptic and paraventricular hypothalamic nuclei, and some of them were seen in the lateral preoptic area, lateral hypothalamic area, arcuate nucleus, perifornical region, post...
