菌株特异性浆细胞能够产生清除挑战性病原体所必需的中和抗体。这些中和抗体也作为抵抗宿主中疾病建立的主要防御起作用。然而,当一种快速突变的病原体感染宿主时,成功控制入侵需要将浆细胞的产生从菌株特异性转变为广泛反应性。在这项研究中,我们开发了一个数学模型的germinal中心动态,并使用它来预测的事件,导致改善的浆细胞反应的广度。我们研究了导致由来自单个菌株特异性克隆、单个广泛反应性克隆或两个克隆的B细胞组成的生发中心的情况。我们发现,最初的B细胞克隆组成,T-滤泡辅助细胞信号,生产性体细胞超突变的增加轮次,和B细胞选择强度是区分感染期间菌株特异性和广泛反应性浆细胞生产的机制之一。了解这些因素对宽度出现的贡献可能有助于促进广泛反应性浆细胞的产生。
Strain-specific plasma cells are capable of producing neutralizing antibodies that are essential for clearance of challenging pathogens. These neutralizing antibodies also function as a main defense against disease establishment in a host. However, when a rapidly mutating pathogen infects a host, successful control of the invasion requires shifting the production of plasma cells from strain-specific to broadly reactive. In this study, we develop a mathematical model of germinal center dynamics and use it to predict the events that lead to improved breadth of the plasma cell response. We examine scenarios that lead to germinal centers that are composed of B-cells that come from a single strain-specific clone, a single broadly reactive clone or both clones. We find that the initial B-cell clonal composition, T-follicular helper cell signaling, increased rounds of productive somatic hypermutation, and B-cell selection strength are among the mechanisms differentiating between strain-specific and broadly reactive plasma cell production during infections. Understanding the contribution of these factors to emergence of breadth may assist in boosting broadly reactive plasma cells production.
