Scientists have known for decades that a type of immune cells called circulating T cells (CT) are present in the blood and that these cells are necessary for the separate shoots and vital functions of choking soldiers. Now breakthroughs led by scientists from Columbia Engineering and the Broad Institute have confirmed this new insight.

The findings demonstrate that a new technique known as Quantitative cellular analysis can accurately measure a broad range of CTCs outside of the bodies of the subjects tested for their effectiveness in identifying and tracking the presence of CTCs (cells of the innate immune system) and in treating soldiers.

Current CTC measurement methods rely on detecting patterns in blood serum rather than dissecting this data into individual cells. Quantitative cellular analysis is an alternative approach that is able to capture an image of the circulating immune system as a whole rather than completing the whole blood sample.

It remains a mystery how the CTCs weve measured in this data are useful for guiding our efforts in combating COVID-19 said the lead researcher Dr. Anny Yin scientist in the lab of Dr. Jennifer Liang professor of biomedical engineering and former mentor in the lab of Dr. Anjesme Laydine. The findings have been published in the journal Nature.
