系来Stain the cells and observe the growth process of the new coronavirus. Electron micrographs of thin slices of the new coronavirus show that the virus particles are released from the surface of infected cells. Li Guosi said that each infected cell will generate thousands of virus particles, which will continue to infect new cells. The researchers also studied samples of the virus at different growth times to better understand the replication process of the virus and compare it with other coronaviruses. According to Bloomberg, Li Guosi is one of the members of the Hong Kong team that isolated and identified the SARS virus. Li Guosi expressed his willingness to cooperate with the world's new coronavirus virus。

实现的The researchers of the strain share relevant information. New Coronavirus Wuhan Strain 01 & nbsp Photo source: National Pathogen Microorganism Resource Bank (China Center for Disease Control and Prevention, Center for Viral Disease Control and Prevention) What new developments have been made? Coronaviruses are a large class of viruses known to cause disease. Patients present with different clinical symptoms ranging from common cold to severe lung infections, such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The new coronavirus 2019-nCov discovered in Wuhan this time is a new coronavirus that has not been previously discovered in humans. Currently, we。

”第220What are the new developments in its research? Computer model: Schematic diagram of the combination of viral S protein and human ACE II protein Genome replication and viral protein synthesis) —The assembled viral genome and viral protein form new virions after assembly, leave the host cell, and then infect other host cells. Cracking the mechanism by which viruses invade host cells can guide the design of drugs, antibodies or vaccines。

In terms of the invasion mechanism, according to a report by the Chinese Science Daily, scientists from the Chinese Academy of Sciences have discovered The cell receptors are the same as SARS-CoV (SARS Coronavirus, Editor's Note) receptors, both ACE2. At present, it is initially found that the binding force of the new virus to the receptor is slightly stronger than that of SARS-CoV. Scientists are studying the ability of the new coronavirus to bind to ACE2 molecules from different species to explore。

研究的结果An intermediate host that may be used when the virus spreads. New Coronavirus Wuhan Strain 02 & nbsp Photo source: National Pathogen Microbiology Resource Library (Institute of Viral Disease Control and Prevention, Chinese Center for Disease Control and Prevention)-About mutant coronavirus is now known as the RNA virus with the largest genome, relative to human DNA For genetic material, the fidelity of RNA genome replication is relatively poor, and it is easy to produce more mutations. Cao Bin, executive vice president of the Institute of Respiratory Diseases of the Chinese Academy of Medical Sciences, said a few days ago that no obvious mutations were found in the viruses isolated from the human body and the environment. However, popular。

支持这样The longer the period, the greater the possibility of mutation. Virology experts and epidemiologists will continue to closely monitor the new coronavirus, and shortening the epidemic period is the key to reducing the risk of virus mutation. Experts from the Chinese Academy of Sciences also said that they are analyzing a more complete genomic variation and tracking the possible variation of the virus during transmission. Data figure: New-type lung weight patients admitted to Wuhan University Zhongnan Hospital. China News Agency reporter Zhou Qunfeng-About the researcher Shi Yi of the Chinese Academy of Sciences and the deputy director of the Key Laboratory of Pathogenic Microbiology and Immunology of the Chinese Academy of Sciences Shi Yi introduced in an interview with the China Science News, by comparing 2019-nCoV and。

7The viral polymerase protein genes of SARS-CoV have been found by scientists to be very similar, at over 90%. Shi Yi also said that about 50 compounds with potential activity have been screened for polymerases by computer virtual screening method, and they are preparing to test and verify the activity. Among the 50 compounds, there is a compound called ritonavir which is an anti-AIDS drug. Recently, researchers from Wuhan Institute of Virology have confirmed that it has antiviral effects at the cell level. Approve the relevant procedures. Scientists also hope to discover more old medicines already in use in hospitals,。
