SARS-CoV-2 Infection Causes Dopaminergic Neuron Senescence [scRNA-Seq]

ABSTRACT: COVID-19 patients commonly present with neurological signs of central nervous system (CNS) and/or peripheral nervous system dysfunction. However, which neural cells are permissive to infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been controversial. Here, we show that midbrain dopamine (DA) neurons derived from human pluripotent stem cells (hPSCs) are selectively susceptible and permissive to SARS-CoV-2 infection, and that SARS-CoV-2 infection triggers a DA neuron inflammatory and cellular senescence response. A high-throughput screen in hPSC-derived DA neurons identified several FDA approved drugs, including riluzole, metformin, and imatinib, that can rescue the cellular senescence phenotype by preventing SARS-CoV-2 infection. RNA-seq analysis of human ventral midbrain tissue from COVID-19 patients, using formalin-fixed paraffin-embedded autopsy samples, confirmed the induction of an inflammatory and cellular senescence signature and identified low levels of SARS-CoV-2 transcripts. Our findings demonstrate that hPSC-derived DA neurons can serve as a disease model to study neuronal susceptibility to SARS-CoV-2 and to identify candidate neuroprotective drugs for COVID-19 patients. The susceptibility of hPSC-derived DA neurons to SARS-CoV-2 and the observed inflammatory and senescence transcriptional responses suggest the need for careful, long-term monitoring of neurological problems in COVID-19 patients.

SARS-CoV-2 Infection Causes Dopaminergic Neuron Senescence

Project description:Here, we show that midbrain dopamine (DA) neurons derived from human pluripotent stem cells (hPSCs) are selectively permissive to SARS-CoV-2 infection both in vitro and upon transplantation in vivo, and that SARS-CoV-2 infection triggers a DA neuron inflammatory and cellular senescence response. A high-throughput screen in hPSC-derived DA neurons identified several FDA approved drugs, including riluzole, metformin, and imatinib, that can rescue the cellular senescence phenotype and prevent SARS-CoV-2 infection. RNA-seq analysis of human ventral midbrain tissue from COVID-19 patients, using formalin-fixed paraffin-embedded autopsy samples, confirmed the induction of an inflammatory and cellular senescence signature and identified low levels of SARS-CoV-2 transcripts.

The susceptibility of hPSC-derived DA neurons to SARS-CoV-2 and the observed inflammatory and senescence transcriptional responses suggest the need for careful, long-term monitoring of neurological problems in COVID-19 patients.

Identification of Drugs Blocking SARS-CoV-2 Infection using hPSC-derived Lung and Colonic Organoids

Project description:The SARS-CoV-2 has already caused over twelve million COVID-19 cases and half a million deaths worldwide. There is an urgent need to create novel models using human disease-relevant cells to study SARS-CoV-2 biology and to facilitate drug screening. As SARS-CoV-2 primarily infects the respiratory tract, we developed a lung organoid model using human pluripotent stem cells (hPSC-LOs) that could be adapted for drug screening. The hPSC-LOs, particularly alveolar type II-like cells, express the viral entry receptor ACE2, are permissive to SARS-CoV-2 infection, and showed robust induction of chemokines and cytokines upon SARS-CoV-2 infection, similar to what is seen in COVID-19 patients. Nearly 25% of these patients have gastrointestinal manifestations, which are associated with worse COVID-19 outcomes1. We therefore also generated complementary hPSC-derived colonic organoids (hPSC-COs) to explore the response of colonic cells to SARS-CoV-2 infection. We found that multiple colonic cell types, especially enterocytes, express ACE2 and are permissive to SARS-CoV-2 infection. Using hPSC-LOs, we performed a high throughput screen of FDA-approved drugs and identified entry inhibitors of SARS-CoV-2, including imatinib, mycophenolic acid (MPA), and quinacrine dihydrochloride (QNHC). Pre- or post-infection treatment at physiologically relevant levels of these drugs significantly inhibited SARS-CoV-2 infection of both hPSC-LOs and hPSC-COs. Together, these data demonstrate that hPSC-LOs and hPSC-COs infected by SARS-CoV-2 can serve as disease models to study SARS-CoV-2 infection and provide a valuable resource for drug screening to identify candidate COVID-19 therapeutics.

A Platform to Define Cellular Targets of SARS-COV-2 Infection Using Human Pluripotent Stem Cell-Derived Cells and Organoids

Project description:The SARS-CoV-2 virus has already caused over a million COVID-19 cases and over fifty-thousand deaths globally. There is an urgent need to create novel models to study SARS-CoV-2 virus using human disease-relevant cells and tissues to understand key features of virus biology. We present a platform comprised of nine different cell and organoid derivatives from human pluripotent stem cells (hPSCs) representing all three primary germ layers, including lung progenitors and alveolar type II (AT2) cells, pancreatic endocrine cells, liver organoids, endothelial cells, cardiomyocytes, macrophages, microglia, and both cortical and dopaminergic neurons. We systematically probed which cell types are permissive to SARS-CoV-2 infection. Human pancreatic beta cells and hepatocytes were strikingly permissive to SARS-CoV-2 infection, further validated using adult primary human islets and liver organoids. Both in vitro and in a humanized mouse model, human lung progenitors and AT2 cells express the ACE2 viral receptor and were highly permissive to SARS-CoV-2 infection. Transcriptomic analysis following SARS-CoV-2 infection of hPSC-derived pancreatic and lung organoids revealed upregulation of chemokines but not type I/III interferon signaling, similar to what was seen in primary human COVID-19 pulmonary infection. Therefore, hPSC-derived cells phenocopy human COVID-19 disease and provide a valuable resource to understand SARS-CoV-2 biology and search for novel therapeutics.

Identification of A Drug Blocking SARS-CoV-2 Infection using Human Pluripotent Stem Cell-derived Colon Organoids

Project description:The current COVID-19 pandemic is caused by the novel coronavirus SARS-coronavirus 2 (SARS-CoV-2). There are currently no therapeutic options for mitigating this disease due to lack of a vaccine and limited knowledge of SARS-CoV-2 virus biology. As a result, there is an urgent need to create new disease models to study SARS-CoV-2 biology and to screen for therapeutics using human disease-relevant tissues. COVID-19 patients often present with respiratory symptoms including cough, dyspnea, and respiratory distress but upwards of 25% of respiratory dysfunction, many COVID-19 patients have digestive system indications, including anorexia, diarrhea, vomiting, and abdominal pain. Moreover, these symptoms are associated with more severe COVID-19 outcomes1. Here, we report using human pluripotent stem cell-derived colonic organoids (hPSC-COs) to explore the permissiveness of different colonic cell types to SARS-CoV-2 infection. Single cell RNA-seq and immunostaining showed that the putative viral entry receptor ACE2 is expressed in multiple types of hESC-derived colon cells, but are highly enriched in hPSC-derivedKRT20+ enterocytes. Distinct cell types in the COs can be infected by a SARS-CoV-2 pseudo-entry virus, which is further validated in vivo using a humanized mouse model. Finally, we adapted hPSC-derived COs to a high throughput platform to screen 1280 FDA-approved drugs. Mycophenolic acid was found to block the entry of SARS-Cov-2 pseudo-entry virus in COs, and confirmed to block infection of SARS-CoV-2 virus. In summary, this study established both in vitro and in vivo organoid models to investigate infection of SARS-CoV-2 disease-relevant human colonic cell types and identified a drug suitable for rapid clinical testing that blocks SARS-CoV-2 infection.

Linear epitope-specific IgG responses to SARS-CoV-2 and related human coronaviruses in human COVID-19 convalescent sera

Project description:The on-going COVID-19 pandemic requires a deeper understanding of the long-term antibody responses that persist following SARS-CoV-2 infection. To that end, we determined epitope-specific IgG antibody responses in COVID-19 convalescent sera collected at 5 months post-diagnosis and compared that to sera from naïve individuals. Each serum sample was reacted with a high-density peptide microarray representing the complete proteome of SARS-CoV-2 as 15 mer peptides with 11 amino acid overlap and homologs of spike glycoprotein, nucleoprotein, membrane protein, and envelope small membrane protein from related human coronaviruses. Binding signatures were compared between COVID-19 convalescent patients and naïve individuals using the web service tool EPIphany.

Senescent endothelial cells are predisposed to SARS-CoV-2 infection and subsequent endothelial dysfunction

Project description:The coronavirus disease 2019 (COVID-19), caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), remains to spread worldwide. COVID-19 is characterized by the striking high mortality in elderly; however, its mechanistic insights remain unclear. Systemic thrombosis has been highlighted in the pathogenesis of COVID-19, and lung microangiopathy in association with endothelial cells (ECs) injury has been reported by post-mortem analysis of the lungs. Here, we experimentally investigated the SARS-CoV-2 infection in cultured human ECs, and performed a comparative analysis for post-infection molecular events using early passage and replicative senescent ECs. We found that; 1) SARS-CoV-2 infects ECs but does not replicate and disappears in 72 hours without causing severe cell damage, 2) Senescent ECs are highly susceptible to SARS-CoV-2 infection, 3) SARS-CoV-2 infection alters various genes expression, which could cause EC dysfunctions, 4) More genes expression is affected in senescent ECs by SARS-CoV-2 infection than in early passage ECs, which might causes further exacerbated dysfunction in senescent ECs. These data suggest that sustained EC dysfunctions due to SARS-CoV-2 infection may contribute to the microangiopathy in the lungs, leading to deteriorated inflammation and thrombosis in COVID-19. Our data also suggest a possible causative role of EC senescence in the aggravated disease in elder COVID-19 patients.

An Airway Organoid-Based Screen Identifies a Role for the HIF1α-Glycolysis Axis in SARS-CoV-2 Infection

Project description:SARS-CoV-2 causes the COVID-19 pandemic. It is urgent to develop disease models to dissect mechanisms regulating SARS-CoV-2 infection. Here, we derive airway organoids from human pluripotent stem cells (hPSC-AOs). The hPSC-AOs, particularly ciliated-like cells, are permissive to SARS-CoV-2 infection. Using this platform, we perform a high content screen and identify GW6471, which blocks SARS-CoV-2 infection. GW6471 can also block infection of the B.1.351 SARS-CoV-2 variant. RNA-seq analysis suggests that GW6471 blocks SARS-CoV-2 infection at least in part by inhibiting HIF1α, which is further validated by chemical inhibitor and genetic perturbation targeting HIF1α. Metabolic profiling identifies decreased rates of glycolysis upon GW6471 treatment, consistent with transcriptome profiling. Finally, xanthohumol, 5-(Tetradecyloxy)-2-furoic acid, and ND-646, three compounds that suppress fatty acid biosynthesis, also block SARS-CoV-2 infection. Together, a high content screen coupled with transcriptome and metabolic profiling reveals a key role of the HIF1α-glycolysis axis in mediating SARS-CoV-2 infection of human airway epithelium.
