Cell type-specific expression of the putative SARS-CoV-2 receptor ACE2 in human hearts

Key Points

• The study aims to investigate the specific expression of ACE2, the receptor for SARS-CoV-2, in human heart tissues.
• Analyzed heart tissue samples for ACE2 expression across different cell types.
• Used immunohistochemistry to assess receptor localization.
• Focused on understanding implications for COVID-19-related cardiac issues.
• Found variable ACE2 expression levels in heart cell types.
• Identified significant ACE2 expression in endothelial cells, suggesting a pathway for SARS-CoV-2 entry.
• Results highlight a potential link between COVID-19 and cardiovascular complications.
