Despite smaller physiological variations (circadian changes, ovulatory cycle, exercise, etc.), deep body temperature is relatively stable (depending on species) due to regulatory processes (Fig. 1). Core temperature is one of the components of milieu intérieur, similarly to other components it contributes to the stability of physiological functions. The basic physiological regulation is determi...

Zn deficiency reduces food intake and growth rate in rodents. To determine the relationship between Zn deficiency and the regulation of food intake, we evaluated leptin gene expression in epididymal white adipose tissue (eWAT), and hypothalamic corticotropin-releasing hormone (hCRH) and hypothalamic neuropeptide Y (hNPY) of rats Zn-deficient only to show reduced food intake and growth rate but ...

Food intake and energy metabolism are tightly controlled to maintain stable energy homeostasis and healthy states. Thus, animals detect their stored energy levels, and based on this, they determine appropriate food intake and meal size. Drosophila melanogaster putative G protein-coupled receptor, Bride of sevenless (BOSS) is a highly evolutionarily conserved protein that responds to extracellul...

Glucagon-like Peptide 1 (GLP-1)-expressing neurons in the hindbrain send robust projections to the paraventricular nucleus of the hypothalamus (PVN), which is involved in the regulation of food intake. Here, we describe that stimulation of GLP-1 afferent fibers within the PVN is sufficient to suppress food intake independent of glutamate release. We also show that GLP-1 receptor (GLP-1R) activa...

A number of neuropeptide Y (NPY) receptor subtypes, including the recently cloned Y5 receptor, have been implicated in the stimulation of food intake. In the present study, Y5 receptor antisense oligodeoxynucleotides (ODNs) were used to assess the potential involvement of the Y5 receptor in the regulation of spontaneous as well as NPY-induced food intake. Repeated central administration of Y5 a...

BACKGROUND AND AIMS Gastrointestinal inflammation reduces food intake but the biological mechanisms explaining suppressed feeding during inflammation are unknown. We have used a model of upper gut infection (Trichinella spiralis in the mouse) to study the effect of inflammation on food intake, and explored the role of a key enteroendocrine cell (EEC) in the regulation of feeding by the immune r...

ALTHOUGH IT HAS BEEN WIDELY ACCEPTED for more than a decade that central or peripheral administration of glucagon-like peptide-1 (GLP-1) causes reduced food intake, it has also been debated whether the reductions were due to engagement of distinct physiological pathways of food intake regulation or, alternatively, if the subjects felt so ill that they reduced food intake. In the current issue o...
