Chemosensory signalling pathways involved in sensing of amino acids by the ghrelin cell

2015

AbstractTaste receptors on enteroendocrine cells sense nutrients and transmit signals that control gut hormone release. This study aimed to investigate the amino acid (AA) sensing mechanisms of the ghrelin cell in a gastric ghrelinoma cell line, tissue segments and mice. Peptone and specific classes of amino acids stimulate ghrelin secretion in the ghrelinoma cell line. Sensing of L-Phe occurs via the CaSR, monosodium glutamate via the TAS1R1-TAS1R3 while L-Ala and peptone act via 2 different amino acid taste receptors: CaSR & TAS1R1-TAS1R3 and CaSR & GPRC6A, respectively. The stimulatory effect of peptone on ghrelin release was mimicked ex vivo in gastric but not in jejunal tissue …

Glucagon-like peptide-2 analog and inflammatory state in obese mice

2020

Obesity is characterized by chronic low grade of systemic inflammation that develops in response to nutrient excess and plays a key role in the pathogenesis of insulin resistance. It is characterized by macrophage infiltration into adipose tissue (AT) and abnormal cytokine production. These factors damage the metabolic homeostasis leading to alteration in the insulin signaling in specific tissues and organs such as AT and liver. Thus, obese subjects develop over the time resistance to the cellular actions of insulin. Glucagon like peptide-2 (GLP-2) is an intestinal proglucagon-derived hormone released together with GLP1, in response to the passage of food by the distal small intestine. Once…
