Researchers have discovered that targeting PD-L1 recycling in myeloid cells enhances T-cell activation and boosts the effects of checkpoint blockade therapies.
A new antibody, H1A, shows promise for improving treatment outcomes.
Mayo Clinic researchers have identified a specific immune cell that can be targeted to give a boost to standard immunotherapies for cancer.
Two research teams found that "first-responder" immune cells known as myeloid cells can be manipulated to enhance the activity of tumor-killing T cells.
The finding suggests that enhanced myeloid cells may boost certain immune checkpoint therapies, which are the standard of care for some cancers but may not have lasting effects.
