The Chinese scientific research team has verified that the pathogenic and toxic forces of Omircong's mutant strains have been greatly reduced. Under the protection of vaccine, the harmfulness of coronal virus to the human body is not as good as before.
According to the Global Times on Thursday (December 1), the research team led by Lan Ke, director of the National Key Laboratory of Virus of Wuhan University in China, found in the virus in vitro infection experiment that Omikon mutant strainsThe ability to infect human lung cells (Calu-3) is significantly lower than that of primitive strains, and the replication efficiency in the cells is more than 10 times lower than that of the original strain.
It is also found in the mouse infection model that the original strain that only needs only 25 to 50 infected doses can cause mice to die.Only the unit can kill mice.And the lung virus content after the infection of Omikon is at least 100 times lower than that of the infected primitive strain.
Lan Ke said that these experiments can effectively show that compared with the primitive strain of the coronary virus, the pathogenic and poisonous power of the Corporal Virus Omircor Rongjon has greatly reduced."This suggests that we don't have to panic over Omikon. For ordinary people, under the protection of vaccines, the harm of coronal virus to the human body is not as good as before."
The University of Hong Kong University ResearchThe team and the key laboratory research team of the Ministry of Tropical Transformation Medical and Education of Hainan Medical College has published a research paper published in the well -known scientific magazine earlier this year, showing that in November 2021, Omikon B.1.1.529 mutant plants appeared in November 2021.Calu3 and intestinal epithelial cell CACO2 in human lung epithelial cells have obviously weakened.Among human lung epithelial cells, the replication efficiency of Omircor's strains is more than three times lower than that of primitive strains.Alpha, Beta, and Delta are the opposite. The replication efficiency of these mutant strains is similar to that of primitive strains or higher than primitive strains.The infectious animal model established among the human ACE2 transgenic mice has further confirmed that compared with the original strain and other mutant plants, the reproductive ability and pathogenicity of Omircor's mutant strains in mice have weakened.The mortality rate is also the lowest.
In the middle of this month, the person in charge of the research department of the National Institute of Allergies and Infectious Diseases, Neiljie Van Dorraman and others, published in the progress of science and progress of academic journalsA paper also expresses similar views.This paper pointed out that the infectious animal model established among the henge monkeys shows that the Ganges monkey infected with Omikon BA.1 or BA.2 mutant strains is far lower than the Ganges monkey infected with Delta strains.Through the display of the Ganges monkey nasal swab test, bronchial cell sampling, and lung tissue cell sample display, the infected virus load infected with Omikon BA.1 or BA.2 mutant strain was significantly reduced.
