What marker is expressed in central memory cells and not effector memory cells?
CCR7
What marker is characteristic of exhausted T cells?
PD-1
What happens to T effector memory cells and T central memory cells with age? What are the markers?
T effector memory cells (CD8+ T cells CD57+) increase with age
T central memory cells (CD8+ T cells CCR7+) decrease with age
What happens to naive and effector cells over time? What are the markers?
CD45+RA+ naive cells decrease over time
CD45+RO+ memory cells increase over time
What are the markers on pre-exhausted T effector memory cells (Temra)?
CD57+RA+
