People with high levels of immune cells that fight the common cold are less likely to get the new coronavirus infection (COVID19), according to a study released by Imperial College London on the 10th. became.
According to the results of the study published in Nature Communications, people who lived with a new coronavirus infection but did not develop it had a common cold caused by another coronavirus before that. It was found that the level of T cells in the body was high.
As the new corona pandemic enters its third year, this study provides further evidence of a protective effect on T cells. Attention is increasing to T cells as new mutants, such as the Omicron strain, reduce the effectiveness of the vaccine.
Reasons why T cells exert their strength and become less severe due to Omicron infection-two studies
“I didn’t always get it when I was exposed to the new coronavirus, and I wanted to know why,” said Leah Kundu, who led the study. “When I was infected with another human coronavirus, such as a common cold.” It has been found that if the past T cells produced in the body are at a high level, the new corona can also be protected. “
The researchers analyzed blood samples from 52 people who lived with the new corona-positive people, and said that half of them had no infection. The team claims that the team is the first to show the role that T cells activated by other coronaviruses play in the defense of new coronavirus infections.
