It is known that the elderly are most often affected by the coronavirus.
Experts conducted a study, as a result of which they were able to find out why COVID-19 is so dangerous for this particular category of the population, ToDay News Ufa reports.
For the elderly, there is a danger of deterioration in the function of T-killers. It is related to age.
Killer T cells are immune cells that destroy cells infected with the virus. Killer T cells inject toxins there that kill the infection.
In older people, these cells are less toxic, so the virus spreads unhindered throughout the body. For this reason, the older a person is, the harder he suffers from the disease.
But there is a possibility to artificially activate T-cells. Scientists conducted an experiment on rodents, which showed good results, but not in all cases this leads to the expected effect.
Earlier, Pravda.Ru wrote that the number of victims of COVID-19 in the world has exceeded a million.
