General description
IGF1 (insulin-like growth factor 1) protein is cleaved into des-N-(1-3)-IGF-1 and an N-terminal Gly-Pro-Glu (GPE tripeptide). It is thought to be an outcome of specific neural processing.
Biochem/physiol Actions
Gly-Pro-Glu (GPE) is a neuroactive peptide and prevents the binding of glutamate to N-methyl-D-aspartate (NMDA) receptor. It positively regulates the potassium-mediated release of acetylcholine from rat cortical slices. Thus, it is involved in the control of brain function. In vitro studies show that this peptide confers neuroprotection to CA1-2 hippocampal neurons against excitotoxic insult.
Gly-Pro-Glu is a neuroprotective compound and the N-terminal tripeptide of IGF-1.
Gly-Pro-Glu is a neuroprotective compound and the N-terminal tripeptide of IGF-1. Gly-Pro-Glu is neuroprotective after central administration in animal models of neurodegenerative processes, such as Huntington′s, Parkinson′s, Alzheimer′s diseases, and varies acute brain injury animal models. The neuroprotective activity is not related to its affinity to glutamate receptor. Findings indicate that GPE mimics insulin-like growth factor I effects on the somatostatin system through a mechanism independent of β-amyloid clearance that involves modulation of calcium and glycogen synthase kinase 3β signaling.

The effect of the N-terminal tripeptide of insulin-like growth factor (IGF)-1, glycine-proline-glutamate (GPE), as a neuroprotective agent for nigro-striatal dopaminergic neurons was examined in the present study using a rat model of Parkinson's disease. A unilateral nigro-striatal lesion was induced

A truncated form of IGF-1 which lacks the aminoterminal tripeptide Gly-Pro-Glu (GPE) is found in human brain. It was proposed that GPE may result from neural specific processing and also have a function within the CNS. GPE was synthesized and

Microbial spoilage causes food losses in the food industry and as such, the use of synthetic chemical preservatives is still required. The current study proposes the use of agro-waste, i.e., grape pomace extracts (GPE), as production medium for biopreservation compounds.

Huntington's disease is an incurable genetic neurological disorder characterized by the relatively selective degeneration of the striatum. Lesioning of the striatum in rodents using the excitatory amino acid agonist, quinolinic acid (QA), effectively mimics the human neuropathology seen in Huntington's
