US and Japanese scientists recently discovered the 1918 pandemic deadly gene
Researchers in the United States and Japan have recently discovered that a genome formed by three genes may be the culprit leading to the 1918 pandemic, a finding that may contribute to the development of new influenza drugs.
Researchers at the University of Wisconsin and the University of Tokyo in Japan reported in a new issue of the Proceedings of the National Academy of Sciences that they identified these three by mixing samples of 1918 influenza virus variants with samples of seasonal influenza viruses. The genes - PA, PB1 and PB2 - form a genome that allows the influenza virus to enter the lungs and cause pneumonia.
New study finds two human genes related to avian influenza
A research team at the University of Chicago found that the mechanism by which the H5N1 avian influenza virus infects human lung epithelial cells is related to two human genes, so a new approach to antiviral development can be developed by affecting these two genes.
Related papers were published on the 10th in the new American academic journal Cell Report. The researchers said that when the H5N1 avian influenza virus infects the human body, it often invades through the lung epithelial cells. To screen which genes are involved in viral infection mechanisms, the researchers used gene editing techniques to create about 19,000 lung epithelial cells with different genetic variants that exposed them to the H5N1 virus.
It was found that the gene named SLC35A1 is responsible for encoding a receptor on the cell surface that the virus can use to "land" on the cell surface. If you knock it out, the virus loses the "hand" of the infected host.
Another gene, called CIC, regulates the immune response, which suppresses the immune response of cells to foreign pathogens. If it is turned off, the immune response will be stronger and help fight the bird flu virus.
