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.

The short version
- 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.
- Scientists typically identify these cells using fluorescent labels that attach to specific surface markers.
- While effective, those methods provide limited information about how the cells are functioning and can alter the cells during preparation.
What happened
As reported in Biophotonics Discovery, a recent study shows how advanced optical imaging can reveal a previously inaccessible layer of information: the metabolic activity of individual immune cells within a complex blood sample.

Why it matters
"So, the question is, what can we get from them that we aren't already getting?" That question has growing clinical relevance.
