Advanced optical imaging reveals hidden activity in blood immune cells
A routine blood sample contains a diverse collection of immune cells that can reveal important clues about health and disease. These cells, known as peripheral blood mononuclear cells (PBMCs), are widely used to study infections, autoimmune disorders, cancer and the immune system's response to treatment.
