Disease Modeling of Acute Heart Failure Infected by SARS-CoV-2
A significant increase in heart failure markers, including high-sensitivity cardiac troponin I and D-dimer, separated non-survivors from survivors affected by coronavirus disease 2019 (COVID-19) in Wuhan China (Zhou, Yu et al.). A genomic analysis of SARS-CoV-2 causing COVID-19 confirmed that SARS-CoV-2 could strongly bind to Angiotensin-Converting Enzyme 2 (ACE2) (Andersen, Rambaut, et al. 2020) and promote the viral entry into cells (Hoffmann, Kleine-Weber, et al.). Heart muscle and some other organs profoundly express ACE2. While in a healthy heart, ACE2 does not play a significant role, patients with hypertension, diabetes, aging, and other cardiovascular diseases, ACE2 seems to play a critical role to moderate their disease progression. Therefore, we hypothesis that SARS-CoV-2 infection is dangerous for patients with those underlying conditions. They will die by developing acute heart failure. This hypothesis is supported by the other report showing 16.7% and 7.2% complications are cardiac arrhythmia and acute cardiac injury, respectively (Zheng, Ma et al. 2020).
InvivoSciences, Inc. (IVS) mass-produces human micro heart tissues (NuHeart™) derived from human induced pluripotent stem cells (iPSCs) to provide disease modeling services for pharmaceutical developers. NuHeart™ will be used to develop a disease model of the heart contacted with SARS-CoV-2 (using a non-viral spike protein as a start). The system will validate the effects of potential treatments to mitigate the deleterious effects of SARS-CoV-2 binding to ACE2. IVS has developed an automated in vitro high-throughput, high-content phenotypic compound screening platform, Live-in-Tissue Analyzer (LITATM), for the assessment of NuHearts™ growing in 96- and 384 well plates. LITA™ measures contractility, action potential (AP), calcium transient (CaT), and mitochondrial activities to analyze the effects of treatment comprehensively.
