A few days ago, a study pointed out that 15% of the global cases of death due to Wuhan pneumonia may be related to air pollution, a Japanese research team found that if inhaled PM2.5 and other atmospheric pollutants to promote viral infection of the cell surface proteins will increase.
According to Japan’s Kyodo News, a team of Kyoto University professor Yuji Takano (environmental Medicine) and others did research on the relationship between air pollution and Wuhan pneumonia, they injected PM2.5 and other air pollutants into the lungs of mice and found that the virus invaded the cells of “ACE2” and “TMPRSS2”. TMPRSS2″ proteins were increased, especially in the large alveolar cells, which are responsible for maintaining gas exchange.
The results of this experiment are seen as a step toward clarifying the mechanism by which air pollution leads to greater susceptibility to infection, although why these proteins increase remains an unsolved mystery, and the team says further research is needed to clarify the relationship between the human living environment and viral infection.
A paper published in the medical journal Cardiovascular Research at the end of last year, citing health and disease data from the United States and China, concluded that 15% of global deaths due to Wuhan pneumonia may be related to air pollution, and that 27% of deaths in East Asia, which has the highest global harmful pollution index, were attributed to the health effects of air pollution.
In response, the central Epidemic command center expert advisory group convener Zhang Shangchun said that the premise must be the environment to have the virus, if there is no virus present, there is no doubt about the increased risk.
