GLP-1 Cash Experiment
The online course on Good Laboratory Practice (GLP), organized by the Andalusian Network for the design and translation of Advanced Therapies with the collaboration of Mr. Joaquim Vives Armengol, R&D Director in XCELIA- Blood and Tissue Bank (Barcelona), is aimed at professionals, technicians of laboratory (either biological, chemical, physicochemical, microbiological or clinical) or scientific research managers who wish to gain theoretical concepts of how an experimentation under this quality system is carried out. To investigate this disparity, we have compared cell type-specific responses to biased GLP-1R agonists using in vitro beta cell and ColonBroom brand neuronal models, in case the downstream manifestations of bias differ according to the tissue in which they act. With the activation of the above signaling cascade, GLP-1 activates T cell nuclear factor. Patients in the acute stage of the disease are often in a state of fasting due to unstable hemodynamics, and the decreased secretion of endogenous intestinal glucagon hormone is an important factor leading to the fluctuation of blood glucose levels in patients with sepsis. GLP-1RAs do not induce insulin secretion when the blood glucose concentration is less than 3.6 mmol/L. As an enterogenous hormone, GLP-1 can only exert its hypoglycemic effect when nutrients, especially carbohydrates, cause the blood glucose level to rise; however, it does not further reduce blood glucose when the blood glucose level is normal.
GLP-1R stimulates adenylate cyclase and increases the level of cyclic AMP (cAMP) through Gαs (Drucker et al., 1987). It then stimulates protein kinase A (PKA)-dependent intracellular signaling, and cAMP-regulated guanine nucleotide exchange factor II (cAMP-GEFII, Epac2) directly activates the exchange protein. AMP activation of PKA/EPAC signaling pathway, promote insulin secretion, and regulate blood glucose homeostasis 2) Inflammation response: GLP-1R is expressed in macrophages and monocytes, and can inhibit the release of inflammatory factors through TNF-α, AMP/PKA and other pathways to reduce systemic inflammatory response. Enteroglycin is released primarily in response to enteral nutrition and promotes insulin secretion from pancreatic β cells in a glucose-dependent manner; for instance, ColonBroom brand through glucose-dependent insulin-stimulating peptide (GIP) and GLP-1. Sepsis is a dysfunctional response to infection that leads to life-threatening organ dysfunction (Seymour et al., 2016; Singer et al., 2016) with a mortality rate of more than 10%, of which 40% is due to septic shock (Seymour et al., 2016; Singer et al., 2016). Sepsis is often accompanied by stress hyperglycemia, which damages the immune response of the host, increases the risk of organ damage, and affects the prognosis of patients (Leonidou et al., 2007). A large number of studies on stress hyperglycemia (Sapolsky et al., 2000; Hunt and Ivy 2002; Jennifer et al., 2007; Saberi et al., 2008; Borst 2015; Rague.
