保护性高亲和力抗体反应取决于生发中心滤泡辅助 T (TFH) 细胞对携带体细胞突变 B 细胞受体的 B 细胞的竞争性选择。在此过程中发生的快速 T-B 细胞相互作用让人想起神经突触传递途径。在这里,我们发现一部分人类 TFH 细胞含有以嗜铬粒蛋白 B 为标记的致密核心颗粒,这些颗粒通常存在于储存儿茶酚胺(如多巴胺)的神经元突触前末梢中。 TFH 细胞产生大量多巴胺,并在与 B 细胞相互作用时释放它。多巴胺导致细胞内 ICOSL(诱导性 T 细胞共刺激配体,也称为 ICOSLG)快速易位至 B 细胞表面,从而增强 CD40L 和嗜铬粒蛋白 B 颗粒在人 TFH 细胞突触处的积累,并增加突触面积。数学模型表明,多巴胺诱导的 T-B 细胞相互作用加快会增加生发中心的总输出,并使其加速数天。面对感染时,穿过 T-B 细胞突触传递神经递质可能是有利的。
Protective high-affinity antibody responses depend on competitive selection of B cells carrying somatically mutated B-cell receptors by follicular helper T (TFH) cells in germinal centres. The rapid T-B-cell interactions that occur during this process are reminiscent of neural synaptic transmission pathways. Here we show that a proportion of human TFH cells contained dense-core granules marked by chromogranin B, which are normally found in neuronal presynaptic terminals storing catecholamines such as dopamine. TFH cells produce high amounts of dopamine and released it upon cognate interaction with B cells. Dopamine causes rapid translocation of intracellular ICOSL (inducible T-cell co-stimulator ligand, also known as ICOSLG) to the B-cell surface, which enhances accumulation of CD40L and chromogranin B granules at the human TFH cell synapse and increases the synapse area. Mathematical modelling suggests that faster dopamine-induced T-B-cell interactions increase total germinal centre output and accelerate it by days. Delivery of neurotransmitters across the T-B-cell synapse may be advantageous in the face of infection.
