感染或疫苗接种导致生发中心(GC)的发展,其中B细胞进化高亲和力抗原受体,最终产生抗体形成浆细胞或记忆B细胞。在这里,我们跟踪B细胞从生发中心(BEM)出现的迁移途径,并发现许多BEM细胞迁移到淋巴结包膜下窦(SCS)的鞘氨醇-1-磷酸(S1 P)的指导下。从SCS,BEM细胞可以离开淋巴结进入远端组织,而一些BEM细胞与SCS巨噬细胞相互作用并从SCS巨噬细胞摄取抗原,然后由CCL 21引导返回GC。局部CCL 21梯度的破坏抑制BEM细胞的再循环,并导致对抗原变异的适应效率降低。因此,我们的研究结果表明,抗原变体特异性BEM细胞的回收和抗原转运回GC可能支持抗原漂移的亲和力成熟。活化的B细胞进入生发中心(GC)成为浆细胞和记忆B细胞。在此,作者表明,一些记忆B细胞通过CCL-21介导的趋化性再循环至GC,以从淋巴结被膜下窦(SCS)递送抗原,从而潜在地促进亲和力成熟和抗原漂移。
Infection or vaccination leads to the development of germinal centers (GC) where B cells evolve high affinity antigen receptors, eventually producing antibody-forming plasma cells or memory B cells. Here we follow the migratory pathways of B cells emerging from germinal centers (BEM) and find that many BEM cells migrate into the lymph node subcapsular sinus (SCS) guided by sphingosine-1-phosphate (S1P). From the SCS, BEM cells may exit the lymph node to enter distant tissues, while some BEM cells interact with and take up antigen from SCS macrophages, followed by CCL21-guided return towards the GC. Disruption of local CCL21 gradients inhibits the recycling of BEM cells and results in less efficient adaption to antigenic variation. Our findings thus suggest that the recycling of antigen variant-specific BEM cells and transport of antigen back to GC may support affinity maturation to antigenic drift. Activated B cell enter germinal centers (GC) to become plasma cells and memory B cells. Here the authors show that some memory B cells recycle to GC via CCL-21 mediated chemotaxis to deliver antigens from the lymph node subcapsular sinus (SCS) to potentially contribute to affinity maturation and antigenic drift.
