  • 摘要:Fibroblast growth factors (FGF) isolated from bovine brain have been identified chemically and immunologically as components of the myelin basic protein. The intact bovine basic protein molecule (170 residues), prepared by the standard acid extraction procedure, lacked mitogenic activity (tested at concentrations up to 10 microgram/ml). However, the polypeptide FGF-2, identified as residues 44-153 of the basic protein, was maximally mitogenic for fibroblasts at 10 ng/ml and polypeptide 44-166 (FGF-1) was maximally active at 100 ng/ml. Pituitary-derived FGF is a potent a growth factor as FGF-2, but appears to be biochemically and immunologically distinct from brain-derived FGF. FGF released in the central or peripheral nervous system as a consequence of myelin damage and basic protein proteolysis could provide a physiological stimulus for wound healing and myelin repair.
