Oct 10, 2017 · Long-term GCC agonist exposure rescues mutant CFTR function in CF patient–derived intestinal organoids. Patient-derived duodenal biopsies are a valuable resource for initiating long-term intestinal culture, and the generated organoids/enterospheres closely mimic the functional profile of the donor intestine. Glucocorticoids (or, less commonly, glucocorticosteroids) are a class of corticosteroids, which are a class of steroid hormones.Glucocorticoids are corticosteroids that bind to the glucocorticoid receptor that is present in almost every vertebrate animal cell. The name "glucocorticoid" is a portmanteau (glucose + cortex + steroid) and is composed from its …An agonist is a molecule that can bind and activate a receptor to induce a biological reaction. The activity mediated by agonists are opposed by antagonists, which inhibit the biological response induced by an agonist. The level of agonist required to induce a desired biological response is referred to as potency.742. Overall, Kristensen and colleagues’ updated meta-analysis nicely synthesises the data from all the major GLP-1 receptor agonist cardiovascular outcome trials reported so far, providing novel insights into these important data. However, many questions remain to be answered, especially regarding benefit in primary prevention patients. Guanylate cyclase 2C (GC-C) is an enzyme expressed mainly in intestinal neurons. Activation of GC-C amplifies the excitatory cell response that is modulated by glutamate and acetylcholine receptors. GC-C, while known mainly for its secretory regulation in the intestinal epithelium, is also expressed in the brain.

As expected from the agonists of GC-C, both plecanatide and dolcanatide exhibited potent cGMP-stimulatory activity in T84 cells.
