1神经生长因子及受体研究现况与进展NGF是在40年前被发现的一种多肽激素,它能促进感觉神经元和交感神经元支配的神经纤维的生长,含有α、β、γ3种亚基的多聚体,可表示为α2βγ2,其中β亚基具有NGF的所有生物学活性,也是3种亚基中唯一具有NGF的所有生物学活性的亚基,β亚基由2 1 Nerve growth factor and receptor research status and progress NGF is a polypeptide hormone found 40 years ago, it can promote the sensory and sympathetic neurons at the innervation of nerve fiber growth, containing α, β, γ3 species The subunit multimer, which can be expressed as α2βγ2, wherein the β subunit has all of the biological activities of NGF and is also the only subunit of all three of the three subunits with all of the biological activities of NGF. The β subunit consists of 2
