目的 :ｔｒｋＡ、ｔｒｋＢ、ｔｒｋＣ是神经生长因子受体家族的三个成员 ,大量的研究已证实 ,神经生长因子家族成员作用的发挥是通过与其相应受体结合来实现的 ,了解这些受体在组织细胞的分布 ,有助于间接了解各神经生长因子家族成员的生理功能。尽管已有文献报道这些受体在成 AIM: TrkA, trkB, trkC are three members of the NGFR family. Numerous studies have demonstrated that the role of NGF family members is mediated through their association with their respective receptors, and understanding of the role of these receptors in tissue The distribution of cells helps to indirectly understand the physiological functions of various members of the nerve growth factor family. Although there are reports of these receptors in the literature
