Preparation and Identification of Neuropilin-1 Monoclonal Antibody
Neuropilins(NRPs)是一个新型的多功能受体,通过与3型semaphorins的结合,能够介导神经系统的发育,同时,通过与VEGF(vascularendothelialgrowthfactor)家族的结合,介导血管的生成。NRPs家族包括NRP-1和NRP-22个成员,其中NRP-1在神经和心血管的发育中起到了关键性的作用;而NRP-2则在神经和淋巴管的生长过程中发挥作用。更重要的是,NRPs高表达于多种肿瘤细胞表面,并参与肿瘤的生长和肿瘤血管的生成。研究显示,阻断NRP-1与VEGF的结合,既能直接抑制肿瘤的生长,也能通过抑制肿瘤血管的生成间接抑制肿瘤生长。因此,NRP-1被认...Neuropilins (NRPs) are multifunctional co-receptors for class 3 semaphorins with critical roles in axonal guidance, and for members of the VEGF (vascular endothelial growth factor) family of angiogenesis. Two members of NRPs, NRP-1 and NRP-2, are confirmed that NRP-1 is essential for neuronal and cardiovascular development, whereas NRP-2 has key role in neuronal patterning and lymphangiogenesis.
