The key symptoms of coronavirus are now widely known as a new and persistent cough, a high temperature and a loss of taste and smell. But many have been left mystified as to why the respiratory infection would prevent someone from being able to smell.
Now, scientists say they have the answer – and it’s promising news if you’re someone who still hasn’t had their sense of smell back yet. A team of experts at Harvard Medical School have identified the cell group which is most vulnerable to Covid-19. They found the neurons that detect and transmit the sense of smell to the brain are not part of the vulnerable cells. Researchers did however discover that the ACE 2 receptor protein that Covid uses to enter human cells is found in cells that provide metabolic and structural support.
Non neural cells are found in the central nervous system.
The experts said that their research suggests that it is these cells that are responsible for anosmia (loss of taste and smell) in Covid-19 patients.
