在慢性病毒感染期间,免疫系统清除病原体的能力是有限的,只有在生发中心B细胞经历多轮体细胞超突变后,才能产生强大的、长寿的血浆和记忆B细胞。在本文中,我们通过建立B细胞体细胞超突变动力学的数学模型来研究生发中心B细胞的形成机制。我们使用这些模型来确定B细胞的选择和对T滤泡辅助细胞和抗原的竞争如何影响急性和慢性感染中生发中心的大小和组成。我们预测T滤泡辅助细胞是驱动大量体细胞超突变的有限资源,并提出了在非突变和突变抗原存在的情况下逆转这一限制的可能机制。
The ability of the immune system to clear pathogens is limited during chronic virus infections where potent long-lived plasma and memory B-cells are produced only after germinal center B-cells undergo many rounds of somatic hypermutations. In this paper, we investigate the mechanisms of germinal center B-cell formation by developing mathematical models for the dynamics of B-cell somatic hypermutations. We use the models to determine how B-cell selection and competition for T follicular helper cells and antigen influences the size and composition of germinal centers in acute and chronic infections. We predict that the T follicular helper cells are a limiting resource in driving large numbers of somatic hypermutations and present possible mechanisms that can revert this limitation in the presence of non-mutating and mutating antigen.
