             [摘    要] 淋巴毒素α、β及其受体(lymphotoxin alpha receptor、lymphotoxin beta receptor,LTAR、LTBR)属于肿瘤坏死因子超家
              族,LTBR 信号在淋巴器官发育、维持完整的淋巴结构、诱导抗病原体的免疫反应、介导器官组织的再生和肿瘤发生发展的过
              程中发挥了重要作用。LTBR信号主要通过非经典/经典核转录因子⁃κB(nuclear transcription factor⁃kappa B,NF⁃κB)通路的信
              号转导来诱导趋化因子和黏附分子的分泌,从而促进细胞增殖与分化。LTBR信号不仅在自身免疫系统疾病中发挥作用,而且
              通过不同模型展现了其抗癌与促癌的双重功效。本文将重点围绕LTBR信号在多种器官生长发育和组织受损后的再生中所
              发挥的作用进行综述,以期为再生医学研究提供新的视角。

             [Abstract] Lymphotoxin α,β and its receptor(LTAR,LTBR)belong to the tumor necrosis factor superfamily. LTBR signaling has a
              variety of physiological functions. It includes controlling the development of lymphoid organs,maintaining intact lymphoid structure,
              inducing immune response against pathogens,mediating the regeneration of organs and tissues,and participating in the evolution and
              development of tumors. The non⁃classical/classical nuclear transcription factor⁃kappaB(NF⁃κB)pathway through LTBR signaling
              induces the secretion of chemokines and adhesion molecules to promote cell proliferation and differentiation. LTBR signaling not only
              plays a role in autoimmune diseases,but also has different anti⁃cancer and pro⁃cancer functions through different models. In this
              paper,we will also focus on the regeneration mechanism of LTBR signal after organ development and related tissue damage,so as to
              open up a new perspective for regenerative medicine.
