BACKGROUND In this study, we examined alterations in the hypothalamic reward system related to high-fat diet (HFD) preferences. We previously reported that hypothalamic 2-arachidonoylglycerol (2-AG) and glial fibrillary acid protein (GFAP) were increased after conditioning to the rewarding properties of a HFD. Here, we hypothesized that increased 2-AG influences the hypothalamic reward system. ...
GEBBER, GERARD L,, AND DAVID 's/v. SNYDER. Hypothalamic confrol of the barorecepfor reflexes. Am. J. Physiol. 2 18 ( 1) : 12+ 13 I . 1969.-The elect of hypothalamic stimulation was studied on the cardiac and vascular efferent components of the baroreceptor reflexes. Bradycardia evoked by carotid sinus nerve stimulation or norepinephrine was blocked by hypothalamic stimulation in spinal cats. Th...
In genetically obese leptin-deficient ob/ob mice, adrenalectomy reverses or attenuates the obese phenotype. Relative to lean controls, ob/ob mice also exhibit decreased hypothalamic proopiomelanocortin (POMC) mRNA and increased hypothalamic agouti-related peptide (AGRP) mRNA and neuropeptide Y (NPY) mRNA. It has been hypothesized that this profile of hypothalamic gene expression contributes to ...
Activation or inhibition of hypothalamic GABAergic activity and immunopotentiation or immunosuppression during aging depends on the variation of the amount of dietary protein as well as the duration of its supplementation. Here we evaluate the effect of low (5%) and high (40%) protein diet on the functional state of hypothalamic GABA receptor in the aging brain in albino rats. Consumption of lo...
Normal function of the hypothalamic–pituitary–adrenal (HPA) axis is critical for survival, and its development choreographed age-, sex- context-specific actions. The liver influences HPA ontogeny, integrating diverse endocrine signals that inhibit or activate development. This review examines how developmental changes in expression genes coordinate postnatal multiple systems facilitate maturati...
Hypothalamic damage was induced in age-matched male and female albino mice by goldthioglucose injection, and their food consumption and body weight were compared over the following 60-day period. Sex differences in food consumption were also investigated as a function of palatability of food. Results show no significant sex differences in food consumption, although marked sex differences in bod...
The Influence of Central Insulin Signals on Stress Response in Mice Chi Nok Chong Stress is an anticipatory or actual disruption of homeostasis which triggers physiological responses to prepare for the threat or to reestablish the system’s internal equilibrium. Other than physical stress (e.g. blood loss, infection, pain, and cold) and psychogenic stress (e.g. novel environment (rodent) and imm...
