FGL peptide is a polypeptide derived from the neural cell adhesion molecule (NCAM), specifically from the interconnecting loop region of the second fibronectin type III module. It mimics the interaction of NCAM with fibroblast growth factor receptor (FGFR), promoting neurite outgrowth, neuronal survival, and exhibiting neuroprotective effects.
FGL has been shown to reduce neuroinflammation by attenuating glial cell activation, particularly in aged brains, and has potential therapeutic applications in age-related cognitive decline and neurodegenerative diseases. It is used in research for protein interaction studies, functional analysis, and epitope screening.
