Specific salivary protein may help block new crown infection

A recent research results released by a team of the University of Osaka, Japan show that specific proteins contained in saliva may help block the human cell infection with new coronary virus.

This study believes that the elderly are getting higher with their age, and the amount of saliva secretion is significantly reduced. This population has a higher chance of developing diseases and developing diseases after infection with new coronary viruses, which may be related to this.

According to the research team, the older the human body, the more saliva secretion. After entering the old age, the amount of saliva secretion gradually decreases, and the protein content with anti -virus infection may decrease.

New coronary virus binds to human cells through its surface spiny protein with human cell surface receptor. The researchers were applied to the diluted saliva on the surface of the extracted human cells, and then analyzed the same virus with the same virus infection mechanism as the new crown virus. The results showed that the higher the saliva concentration, the more difficult the virus to be studied with the surface receptor of the human cell.

Among the four kinds of salivary proteins focusing on researchers, the role of "group protein H2A" and "neutral granulocyte elastin" is particularly obvious that the combination of virus and human cell surface receptor is particularly obvious.

Matsumoto Matsumoto, a team member and an associate professor of cell molecular biology, said that it is hoped that this research will help develop new crown drugs that act on human immunity rather than attack viruses.
