A new way to profile immune cells in blood

March 7, 2014 8:42 am | by David Orenstein, Brown Univ. | News | Comments

When a person becomes sick or is exposed to an unwelcome substance, the body mobilizes specific proportions of different immune cells in the blood. Methods of discovering and detecting those profiles are therefore useful both clinically and in research. In a new Genome Biology paper, a team of scientists describes a new and uniquely advantageous way to detect them.
