Project description:Severe cardiovascular complications can occur in coronavirus disease of 2019 (COVID-19) patients. Cardiac damage is attributed mostly to the aberrant host response to acute respiratory infection. However, direct infection of cardiac tissue by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) also occurs. We examined here the cardiac tropism of SARS-CoV-2 in spontaneously beating human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs).These cardiomyocytes express the angiotensin-converting enzyme 2 (ACE2) receptor but not the transmembrane protease serine 2 (TMPRSS2) that mediates spike protein cleavage in the lungs. Nevertheless, SARS-CoV-2 infection of hiPSC-CMs was prolific: viral transcripts accounted for about 88% of total mRNA. In the cytoplasm of infected hiPSC33 CMs, smooth walled exocytic vesicles contained numerous 65-90 nm particles with canonical ribonucleocapsid structures, and virus-like particles with knob-like spikes covered the cell surface. To better understand how SARS-CoV-2 spreads in hiPSC-CMs we engineered an expression vector coding for the spike protein with a monomeric emerald-green fluorescent protein fused to its cytoplasmic tail (S-mEm). Proteolytic processing of S-mEm and the parental spike were equivalent. Live cell imaging tracked spread of S-mEm cell-to-cell and documented formation of syncytia. A cell-permeable, peptide-based molecule that blocks the catalytic site of furin and furin-like proteases abolished cell fusion. A spike mutant with the single amino acid change R682S that disrupts the multibasic furin cleavage motif was fusion inactive. Thus, SARS42 CoV-2 replicates efficiently in hiPSC-CMs and furin and/or furin-like-protease activation of its spike protein is required for fusion-based cytopathology. This hiPSC-CM platform enables target-based drug discovery in cardiac COVID-19.

Project description:Chronic endotheliitis and various cardiovascular co-morbidities are more likely to develop in patients who are recovering from a post-acute SARS-CoV-2 infection. Despite a growing body of clinical data suggesting that the endothelium could be the cause of both cardiac injury and the multi-organ damage found in COVID-19 patients, there is no clear link between endothelial (EC) dysfunction and increased cardiac risk during long COVID. Here, we studied long COVID-19-associated endotheliitis and its implications on cardiac dysfunction. Thrombotic vascular tissues from long COVID patients were harvested and profiled to identify the different mechanisms of viral-induced EC pathogenesis. Human induced pluripotent stem cell (iPSC)–derived ECs were leveraged to model endotheliitis in-a-dish after exposure to SARS-CoV-2, which showed similar EC dysfunction and upregulation of specific cytokines such as CCL2 and IL6, as seen in the primary ECs of long COVID patients. 3D fabricated cardiac organoids generated from iPSC-ECs and iPSC-derived cardiomyocytes (iPSC-CMs) were utilized to understand the pathological influence of endotheliitis on cardiac dysfunction. Notably, cardiac dysfunction was observed only in cardiac organoids that were fabricated with both iPSC-CMs and iPSC-ECs after exposure to SARS-CoV-2. Simultaneous profiling of chromatin accessibility and gene expression dynamics via integration of ATAC-seq and RNA-seq at a single cell resolution revealed CCL2 as the prime cytokine responsible for the non-endothelial “phenotype switching” and the impending cardiac dysfunction in cardiac organoids. This was further validated by high-throughput proteomics that showed CCL2 to be released only by cardiac organoids that were fabricated with iPSC-CMs and iPSC-ECs after SARS-CoV-2 infection. Lastly, disease modeling of the cardiac organoids as well as exposure of human ACE2 transgenic mice to SARS-CoV-2 spike proteins uncovered a putative mechanism for the cardiac dysfunction involving posttranslational modification of cardiac proteins driven by oxidative stress and inflammation. These results suggest that EC-released cytokines can contribute to the pathogenesis of long COVID-associated cardiac dysfunction, and thus a thorough clinical profiling of vascular health could help identify early signs of heart disease in COVID-19 patients.

Project description:Cardiovascular manifestations of COVID-19 include myocardial injury, heart failure, and myocarditis and are associated with long-term disability and mortality. SARS-CoV-2 RNA and antigens are found in the myocardium of COVID-19 patients, and human cardiomyocytes are susceptible to infection in cell or organoid cultures. While these observations raise the possibility that cardiomyocyte infection may contribute to the cardiac sequelae of COVID-19, a causal relationship between cardiomyocyte infection and myocardial dysfunction and pathology has not been established. Here, we generated a mouse model of cardiomyocyte-restricted infection by selectively expressing human angiotensin converting enzyme 2 (hACE2), the SARS-CoV-2 receptor, in cardiomyocytes. Inoculation of Myh6-Cre Rosa26LSL-hAce2 mice with SARS-CoV-2 resulted in viral replication within the heart, accumulation of macrophages, and moderate left ventricular (LV) systolic dysfunction. Cardiac pathology in this model was transient and resolved with viral clearance. Blockade of monocyte trafficking reduced myocardial viral replication and macrophage accumulation and suppressed the development of LV systolic dysfunction. These findings establish a mouse of model of SARS-CoV-2 cardiomyocyte infection that recapitulates features of cardiac dysfunctions of COVID-19 and suggests that both replication and resultant innate immune responses contribute to pathology

Project description:Coronavirus disease 2019 (COVID-19) is a global pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 patients accompany with high frequencies of cardiac complications, which prominently contributed to the overall SARS-CoV-2-caused mortality. SARS-CoV-2 genome was reported to encode up to 14 genes. Currently, molecular mechanisms underlying SARS-CoV-2 viral gene-induced cardiac manifestations still remain elusive. Here, we overexpressed Orf9c, a SARS-CoV-2 encoded gene, in human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs). Multiple genome-wide analyses were performed to investigate the global impacts of Orf9c on hPSC-CMs. The mRNA-seq indicated stress-related signaling pathways, including cell death, immune and inflammation responses, activated by Orf9c. High-throughput proteomics and Co-immunoprecipitation mass spectrometry studies revealed the global influence of Orf9c on the proteome of hPSC-CMs and Orf9c-interactive protein network in hPSC-CMs. Orf9c overexpression elevated protein expressions of key factors essential for apoptosis while suppressing protein factors crucial for ATP synthesis. Further experimental validations confirmed that Orf9c overexpression induced prominent cell death, abnormal calcium handling and electrical properties, and significantly reduced cellular ATP level in hPSC-CMs. Finally, administration of two FDA-approved drugs, Ivermectin and Meclizine, were proven by our study to restore ATP level to prominently ameliorate Orf9c-induced cell death and electrical abnormalities of hPSC-CMs. Overall, we comprehensively manifest global responses of host human heart muscle cells to SARS-CoV-2 gene Orf9c, characterized molecular mechanisms underlying Orf9c-induced cardiac abnormalities, and explored potentially therapeutic approaches to ameliorate cardiac dysfunctions in COVID-19 patients.
