淋巴组织的发育与CD_4+CD_3、−、IL-7R、α在造血细胞中的局部积聚有关,造血细胞将淋巴毒素(LT)α_1、β_2信号传递给常驻基质细胞。以往的研究已经证实,CXCL13(BLC)在Peyer‘s Patches(PP)和一些外周淋巴结(LNS)的形成中起着重要作用,但包括肠系膜LNS在内的几种LN对趋化因子的需求仍未确定。利用另外携带LN T细胞突变缺失(PLT/PLT)的CXCL13−/−小鼠,我们发现CCR7配体在外周LN的发生发展中起作用。我们还测试了在LN发育过程中CXCL13和PP发育所需的细胞因子受体IL-7Rα之间的遗传相互作用。同时缺乏CXCL13和IL-7Rα的小鼠表现出显著的LN缺失,包括肠系膜LN。这些数据将CXCL13的作用扩展到所有LN的发育,并确立了IL-7Rα在这一过程中以前未被认识到的作用。循环和LN CD_4~+CD_3、−、IL-7R、α和HI细胞均以IL-7Rα依赖的方式表达LT-β_1、α_2。此外,CXCL13被发现足以介导CD_4+CD_3−IL-7Rα在体内异位募集细胞。这些结果表明,CXCL13和CCR7配体促进CD_4+CD_3−IL-7Rαhi细胞蓄积,传递IL-7Rα依赖的LTα1β2信号,对LN的发展至关重要。
Lymphoid tissue development is associated with local accumulation of CD4+ CD3− IL-7Rαhi hematopoietic cells that deliver lymphotoxin (LT)α1β2 signals to resident stromal cells. Previous studies have established an important role for CXCL13 (BLC) in the development of Peyer's patches (PP) and some peripheral lymph nodes (LNs), but the chemokine requirements for several LN types, including mesenteric LNs, remain undefined. Using CXCL13−/− mice that additionally carry the paucity of LN T cell mutation (plt/plt), we discovered that CCR7 ligands function in peripheral LN development. We also tested for a genetic interaction during LN development between CXCL13 and a cytokine receptor required in PP development, IL-7Rα. Mice deficient for both CXCL13 and IL-7Rα displayed a striking absence of LNs, including mesenteric LNs. These data extend the role of CXCL13 to the development of all LNs and establish a previously unappreciated role for IL-7Rα in this process. Both circulating and LN CD4+ CD3− IL-7Rαhi cells are shown to express LTα1β2 in an IL-7Rα–dependent manner. Furthermore, CXCL13 was found to be sufficient to mediate CD4+ CD3− IL-7Rαhi cell recruitment in vivo to an ectopic site. These findings indicate that CXCL13 and CCR7 ligands promote accumulation of CD4+ CD3− IL-7Rαhi cells, delivering IL-7Rα–dependent LTα1β2 signals critical for LN development.
