Hypoglycemia , also known as low blood sugar, is when blood sugar decreases to below normal levels. This may result in a variety of symptoms including clumsiness, trouble talking, confusion, loss of consciousness, seizures, or death. A feeling of hunger, sweating, shakiness, and weakness may also be present. Symptoms typically come on quickly.
Effects of low blood glucose within the normal range
Modest decrements in plasma glucose concentration cause early impairment in cognitive function and later activation of glucose counterregulation in the absence of hypoglycemic symptoms in normal man. 1988
Corticotropin-releasing hormone mRNA levels in the paraventricular nucleus of patients with Alzheimer's disease and depression. 1995
CRH-mRNA levels in the paraventricular nucleus of Alzheimer's patients were markedly higher than those of comparison subjects, whereas CRH-mRNA levels in the paraventricular nucleus of depressed patients were even higher than the levels of Alzheimer's patients.
Cyclic adenosine 3',5'-monophosphate responsive element binding protein phosphorylation is required but not sufficient for activation of corticotropin-releasing hormone transcription. 2009
cAMP is a major regulator of CRH transcription.
Corticotropin-releasing factor and adrenocorticotropin stimulate ciliary motility in rabbit tracheal epithelium. 1989
Intracellular cyclic AMP levels were significantly increased by CRF and ACTH.
Class B GPCR’s are activated by peptide ligands, typically 30-40 amino acid residues, that are involved in major physiological functions such as glucose homeostasis (glucagon and glucagon-like peptide 1), calcium homeostasis and bone turnover (parathyroid hormone and calcitonin), and control of the stress axis (corticotropin-releasing factor).
Structural Biology of Class B G-Protein Coupled Receptors , 2009
The secretin family of Class B GPCRs consists of 15 members in humans, including receptors for parathyroid hormone (PTH), glucagon (GCG), glucagon-like-peptide-1 (GLP1), and corticotropin-releasing factor (CRF).
