The hypothalamus consists of several nuclei that ... there are orexigenic coexpressing neuropeptide Y/Agouti gene-related protein (NPY/AgRP) and anorexigenic pro-opiomelanocortin (POMC)/cocaine ...

There are also leptin receptors in MCH neurons of the lateral hypothalamus. Genetic and physiological studies have shown that NPY, AgRP, α-melanocyte-stimulating hormone (α-MSH, a POMC-derived ...

4,5 These ghrelin-containing neurons send efferent fibers to neurons that contain neuropeptide Y (NPY) and agouti-related protein (AgRP)—NPY/AgRP neurons—and might stimulate the release of ...

Within the arcuate nucleus (ARC) of the hypothalamus, leptin influences two key neuronal populations. One, the agouti-related protein (AGRP) and neuropeptide Y (NPY) neurons, stimulates hunger ...

The hypothalamus integrates neurohormonal signaling from gut and adipose tissue. Specific hypothalamic nuclei, including the dorsomedial nucleus (DMN), paraventricular nucleus (PVN) and ...
