Singapore and US researchers have found a simple and fast way to measure T-cell immune response to SARS-COV-2. Article researchers Published in The Journal of Clinical Investigation.
T-cells along with antibodies play a vital role in protecting people from COVID-19, but it is much harder to detect and measure them, “said one of the researchers, Senior Researcher of the University of Duke University and National University of Singapore Anthony Tanoto Tang. Scientists took blood samples in more than 200 volunteers who were vaccinated or sled to COVID-19. Then they introduced directly into blood samples Small fragments of SARS-COV-2 S-COV-2. In response to them, T-cells produced cytokines – small signaling molecules that are significantly easier to detect.
researchers have shown that their test is less than 24 hours to identify, determine the number and functionality of each of the T-cell types present in the blood. In addition, scientists note, their research showed that the level of blood antibodies against SARS-COV-2 does not always correlate with the level of T cells.
