微生物感染过程受到宿主与病原体多重因素的复杂调控，其中微生物的感染能力（infectivity）和暴露剂量（dose）的异质性（heterogeneity）是决定感染概率的关键变量。然而，传统剂量-反应模型（dose–response models）往往忽略微生物群体内和宿主间的异质性差异，导致感染风险评估存在显著偏差。更值得 ...

To study the effects of structural protein mutations on the infectivity of SARS-CoV-2, the authors created a new experimental system which they call SARS-CoV-2 virus-like particles (SC2-VLPs ...
