  • The PVN Powerhouse: How the Paraventricular Nucleus Rules Hormone Secretion

    Hold onto your hypothalamus, folks! We’re about to dive into the wild world of the Paraventricular Nucleus (PVN), where tiny cells pack a mighty hormonal punch! Picture this: deep in the brain’s control center, the hypothalamus, sits the PVN – a cluster of cells that’s like the body’s own hormone factory. But we’re not talking…

  • Pulmonary neuroendocrine cells

    Neuroendocrine cells are cells that receive neuronal input (through neurotransmitters released by nerve cells or neurosecretory cells) and, as a consequence of this input, release messenger molecules (hormones) into the blood. In this way they bring about an integration between the nervous system and the endocrine system, a process known as neuroendocrine integration. An example of a neuroendocrine cell is a cell…

  • Gastrin-releasing peptide aka GRP and Pro-Gastrin-Releasing-Peptide aka Pro-GRP (and something called PreProGRP?)

    Gastrin-releasing peptide, also known as GRP, is a neuropeptide, a regulatory molecule that has been implicated in a number of physiological and pathophysiological processes. Most notably, GRP stimulates the release of gastrin from the G cells of the stomach. Function GRP is also involved in the biology of the circadian system, playing a role in the signaling of light to the master circadian oscillator in…
