Blood type poses a risk of COVID! Scientists found clear evidence from the lab.
Blood type poses a risk of COVID! – March 4 US NewsIt reports that scientists have found evidence that the SARS-CoV-2 coronavirus (SARS-CoV-2), the pathogen of the 2019 coronavirus, or COVID-19 may be capable of infecting humans with “A blood group” more than others
The findings were published in the Medical Journal of Hematology Blood Advances on March 3, 2021, creating a buzz for the medical community. This is another evidence that blood groups may be another risk factor for COVID-19 infection. It was later found that this virus has a significantly higher binding capacity to respiratory cells of people with type A blood than other groups.
In the study, the researchers aimed at the part that the virus binds to target cells, known as receptor binding domain, or RBD, assessing their effectiveness for binding to human respiratory cells with ABO and A blood groups. B. versus red blood cells from people with blood types ABO and AB
The results were found that This virus has a greater binding capacity to human respiratory cells that have A blood group than other blood groups. In the red blood cells, there is no difference. As a result, the research team concluded that May help explain the link between the infectious mechanisms of those with A blood group.
Dr. Sean Stowell, lead researcher from Women’s Hospital, Boston, Massachusetts. The United States said that it was found that this virus favor antigens. The found in the respiratory tissue is of great interest. It is expected that this is the main mechanism of infection that occurs.
“Blood type is a barrier. Because it is something that all human beings inherit We cannot change anything. But if we have a better understanding of the virus infection mechanism that is related to blood type, it should make it possible to find a better way to prevent it, ”said Stowell, MD.
However, the researchers said the research could not predict the full course of the disease. This is because the infectious mechanism of this virus is much more than what is discussed in research.
“Observing the outcome of this study It’s not the only mechanism that occurs when the virus enters our body. But it should help explain how much the influence of blood type affects infection. ”
