Research during quarantine
Fernando Carvall“When I saw the results, I thought: this virus is going to infect everyone” The first reports about the disease in China sparked my curiosity. The Chinese discovered that the virus enters the cells via the angiotensin-converting enzyme 2 [ACE2] receptor. Its expression depends on the ACE2 gene, which plays an important role in...
