Researchers from Memorial Sloan Kettering Cancer Center (MSK) and their colleagues at the University of Pennsylvania (UPenn), in collaboration with the Parker Institute for Cancer Immunotherapy (PICI), studied changes in the blood of patients with stage IV melanoma who were all treated with the PD-1 drug pembrolizumab. Researchers looked at circulating immune cells called T cells that showed signs of being “reinvigorated” by the PD-1 therapy.
