    At present, the shadow of the new crown pneumonia (COVID-19) has not yet dissipated, and is still accelerating globalspreadWith the deepening of global research on the new crown pneumonia, more and more research results have surfacedrecently, Nature magazine reviewed research on COVID-19 over the past six months and suggested five key "soul tortures", including differences in symptoms after infection, how immune is produced, new mutations in the virus, and the source of the virusdoi: 10.1038/d41586-020-01989-z, why do different people behave differently? It is well known that some people are infected with the virus with obvious signs and are susceptible to disease, while others seem to be healthy and have no obvious symptoms, but are patients with new coronary pneumoniaresearchers are trying to find possible explanations for these differencesa team that analyzed the genomes of about 4,000 people from Italy and Spain and found the first major genetic link to the severe COVID-19people with respiratory failure are more likely to carry one of two specific genetic variants than people without the disease, what are the two specific genetic variants? One variant is located in the genomic region that determines the ABO blood type; the other is close to several genes, one of which encodes the protein that the virus interacts with the receptors used to enter human cells, and the other two encode molecules associated with the immune response to pathogensHowimmune to SARS-CoV-2? How long can it last? The answer to this question is focused on neutralizing antibodiesneutralizing antibodies are mainly produced by B lymphocytes, which neutralize toxins and prevent pathogen invasion, while neutralizing antibody titer also has a strong correlation with the number of viral-specific T cells, indicating the importance of T-cells to long-term immunity, for now, researchers still don't know the levels of neutralizing and antibody that are needed to re-infect and mitigate other diseases, the study found that neutralizing antibody levels of SARS-CoV-2 remained high for several weeks after infection, and often began to declinevirologist Shane Crotty said: "Other coronavirus studies have shown that the 'sterilization immunity' against infection can last only a few months, but protective immunity to prevent or relieve symptoms can last for a long timea cross-reactive T-cell between the "circulating " common cold" coronavirus and SARS-CoV-2 to identify whether the virus has really mutated? All viruses mutate when they infect humans, and SARS-CoV-2 is no exceptioncomputational biologist David Robertson of the University of Glasgow in the UK and his team are classifying the SARS-CoV-2 mutationsuch mutations may reduce the effectiveness of the vaccine by altering antibodies and T-cells to identify pathogens , however, most mutations only increase the prevalence of the virus and do not seem to have much effect on the severity of the disease researchers are arguing about a mutation in the virus's spikeprotein the mutation appears to have been present in Europe since February, with most popular viruses carrying it numerous studies have shown that the mutation makes the SARS-CoV-2 virus more infectious to cultured cells, but it is not clear how this trait translates into human infection Picture Source: Has the vaccine developed by NIAID/NIH/SPL already had a noticeable effect? Many scientists believe that an effective vaccine is the only way to eliminate COVID-19 currently has about 200 vaccines in development worldwide, about 20 of which are in clinical trials data from animal studies and early human trials show that the COVID-19 vaccine enables our bodies to produce effective neutralizing antibodies that can prevent viral infections in cells but it is not clear whether the levels of these antibodies are high enough to prevent new infections and how long they last in the body what does the virus come from? Most researchers believe SARS-CoV-2 may have originated from bats, especially horseshoebats 2013, a coronavirus called RATG13 was found in Rhinolophusaffinis in southwestern China's Yunnan province, with 96 percent of the genome of SARS-CoV-2 next, it was rmyn02, a coronavirus found in Therhinohusmalayanus, the same genetic sequence as SARS-CoV-2 study also found that pangolins can carry coronaviruses that share a common ancestor to SARS-CoV-2, but there is no evidence that the virus can be transmitted from pangolinto to humans new crown virus vs bat vs pangolin symnalal although the outbreak of the new crown virus has not yet been eliminated, but to understand the current progress of SARS-CoV-2 research is still a top priority, I believe that soon, we will know it well and successfully take it down Source: smh.com.au: the mysteriesscientists are still racing to solve smh.com.au Targets of t Cell Responses to SARS-CoV-2 Coronavirus in Humans WithCoVID-19 Disease and Unexposed Individuals
