CORONAVIRUS RESEARCH HIGHLIGHTS: 1-MINUTE READS
Recovered monkeys resist re-infection
Monkeys that had recovered from infection with the coronavirus were shown to be protected from re-infection, although how long the protection lasts is unclear. Researchers gave doses of the coronavirus to nine rhesus macaques (Macaca mulatta), which developed mild symptoms and antibodies against the virus. A month later, they gave the monkeys another dose of virus. All nine mounted an antibody response to this second dose, suggesting that their immune systems had fought off the virus.

Virus ravages organs from heart to brain
Autopsies on 27 people with COVID-19 have found the coronavirus not only in the lungs, but also in the kidneys, liver, heart, brain and blood. By scrutinizing databases of genetic activity, researchers also found that three genes known to encourage SARS-CoV-2 infection are highly active in kidney cells. Additional analysis of six people detected virus in all examined kidney compartments, which helps to explain the kidney damage seen in some people with the illness.

Antibody against SARS could help to fight COVID-19
An antibody discovered in the blood of a person who survived severe acute respiratory syndrome (SARS) could potentially help others to fight COVID-19. The new antibody recognizes and blocks both the COVID-19 coronavirus and the one that caused the 2003 SARS outbreak. It works by binding to a viral protein called spike that both viruses use to enter cells.
