摘要：There is a pressing need for effective therapeutics for coronavirus disease 2019(COVID-19),the respiratory disease caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)*** process of drug development is a costly and meticulously paced process,where progress is often hindered by the failure of initially promising *** aid this chal-lenge,in vitro human microphysiological systems need to be refined and adapted for mechanistic studies and drug screening,thereby saving valuable time and resources during a pandemic *** SARS-CoV-2 virus attacks the lung,an organ where the unique three-dimensional(3D)structure of its functional units is critical for proper respiratory *** in vitro lung models essentially recapitulate the distinct tissue structure and the dynamic mechanical and biological interactions between different cell *** model systems include Transwell,organoid and organ-on-a-chip or microphysiological systems(MPSs).We review models that have direct relevance toward modeling the pathology of COVID-19,including the processes of inflammation,edema,coagulation,as well as lung immune *** also consider the practical issues that may influence the design and fabrication of *** role of lung MPS is addressed in the context of multi-organ models,and it is discussed how high-throughput screening and artificial intelligence can be integrated with lung MPS to accelerate drug development for COVID-19 and other infectious diseases.
