G cells or gastrin cells secrete gastrin. They works in conjunction with gastric chief cells and parietal cells. The peptide hormone bombesin also stimulates gastrin from G cells.
Control of stomach acid In anatomy, the G cell or gastrin cell, is a type of cell in the stomach and duodenum that secretes gastrin. It works in conjunction with gastric chief cells and parietal cells. G cells are found deep within the pyloric glands of the stomach antrum, and occasionally in the pancreas and duodenum.
Enterochromaffin-like cells (ECL cells) are neuroendocrine and enteroendocrine cells that aid in the production of gastric acid via the release of histamine
Control of stomach acid Enterochromaffin-like cells or ECL cells are a type of neuroendocrine cell found in the gastric glands of the gastric mucosa beneath the epithelium, in particular in the vicinity of parietal cells, that aid in the production of gastric acid via the release of histamine. They are also considered a

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
Enterochromaffin (EC) cells aka Kulchitsky cells
Enterochromaffin (EC) cells (also known as Kulchitsky cells) are a type of enteroendocrine cell, and neuroendocrine cell. They reside alongside the epithelium lining the lumen of the digestive tract and play a crucial role in gastrointestinal regulation, particularly intestinal motility and secretion. They were discovered by Nikolai Kulchitsky. Bertrand,
Chromaffin cells aka pheochromocytes
Chromaffin cells, also called pheochromocytes (or phaeochromocytes), are neuroendocrine cells found mostly in the medulla of the adrenal glands in mammals. These cells serve a variety of functions such as serving as a response to stress, monitoring carbon dioxide and oxygen concentrations in the body, maintenance of respiration and the
Pistacia terebinthus aka the terebinth and the turpentine tree
Pistacia palaestina, terebinth Pistacia terebinthus also called the terebinth and the turpentine tree, is a deciduous tree species of the genus Pistacia, native to the Mediterranean region from the western regions of Morocco and Portugal to Greece and western and southeastern Turkey. At one time terebinths growing on the eastern shores of the Mediterranean Sea (in Syria, Lebanon and Israel) were regarded as
Homovanillic acid (HVC) and Vanillylmandelic acid (VMA)
Homovanillic acid (HVA) is a major catecholamine metabolite that is produced by a consecutive action of monoamine oxidase and catechol-O-methyltransferase on dopamine. Lambert, G.W.; Eisenhofer, G.; Jennings, G.L.; Esler, M.D. (1993). "Regional homovanillic acid production in humans". Life Sciences. 53 (1): 63â75. doi:10.1016/0024-3205(93)90612-7. PMID 8515683. Homovanillic acid is used as a reagent to detect oxidative enzymes, and is associated with dopamine levels
Catecholamine (CA)
A catecholamine (abbreviated CA) is a monoamine neurotransmitter, an organic compound that has a catechol (benzene with two hydroxyl side groups next to each other) and a side-chain amine.

Buzz Pollination or Sonication
Buzz pollination or sonication is a technique used by some bees, such as solitary bees to release pollen which is more or less firmly held by the anthers.

What is Immunoprecipitation (IP)?
Immunoprecipitation (IP) is a technique used to enrich protein antigens from a complex mixture using specific antibodies. To carry out an IP, antibodies must be coupled to a solid substrate, such as agarose resin or magnetic beads, to allow for
Gastric inhibitory peptide aka GIP and receptors
Gastric inhibitory polypeptide or gastric inhibitory peptide also known as glucose-dependent insulinotropic polypeptide abbreviated as GIP, is an inhibiting hormone of the secretin family of hormones. Meier JJ, Nauck MA (2005). "Glucagon-like peptide 1(GLP-1) in biology and pathology". Diabetes/Metabolism Research and Reviews. 21 (2): 91â117. doi:10.1002/dmrr.538. PMID 15759282. S2CID 39547553. While it is a weak inhibitor of gastric acid secretion, its main role
Gastrin-releasing peptide aka GRP
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. The gene from which GRP is derived encodes a number
Neuromedin U
Neuromedin U (or NmU) is a neuropeptide found in the brain of humans and other mammals, which has a number of diverse functions including contraction of smooth muscle, regulation of blood pressure, pain perception, appetite, bone growth, and hormone release. It was first isolated from the spinal
