The pretreatment of human dendritic cells with interferon-beta enhances their immune response to influenza virus infection. We measured the expression levels of several key players in that response over a period of 13 h both during pretreatment and after viral infection. Their activation profiles reflect the presence of both negative and positive feedback loops in interferon induction and interferon signaling pathway. Based on these measurements, we have developed a comprehensive computational model of cellular immune response that elucidates its mechanism and its dynamics in interferon-pretreated dendritic cells, and provides insights into the effects of duration and strength of pretreatment.
干扰素-β预处理人树突状细胞可增强其对流感病毒感染的免疫反应。我们在预处理和病毒感染后 13 小时的时间内测量了该反应中几个关键分子的表达水平。它们的激活谱反映了干扰素诱导和干扰素信号通路中存在负反馈和正反馈环。基于这些测量,我们开发了一个全面的细胞免疫反应计算模型,阐明了其在预处理树突状细胞中的机制和动态,并深入了解了预处理的持续时间和强度的影响。
