American scientists have explained the loss of smell on the part of those infected with the coronavirus of patients. The results of the study were published in the journal ACS Chemical Neuroscience.
According to some loss of sense of smell the most common symptom of infection of the coronavirus, which can occur in the absence of fever and cough. Experts have found that the proteins with which the virus particles enter the body, are produced by the cells of the nasal cavity. Based on experiments with mice have been able to understand that the greater number of these proteins — receptor ACE2 and TMPRSS2 protease is formed in older individuals. For this reason, in particular, elderly patients suffer heavier disease than the young.
The study says that at the moment there is no information about which cells of the olfactory epithelium of the nasal cavity Express these proteins that contribute to infection COVID-19. Doctors noticed that having this information will help to improve diagnosis and to accelerate the development of vaccines against coronavirus.
At the end of April, an international team of scientists found that some symptoms COVID-19 can occur in a limited number of patients. To non-obvious symptoms of coronavirus, which are likely to have been inherited and have a genetic basis, related muscle aches and loss of smell.
