Immune Cells Team Up to Kill Tumors
How Immune Cells Work Together to Kill Tumors
How immune cells work together to kill tumors is becoming clearer thanks to a promising new discovery from scientists at Emory’s Winship Cancer Institute. They found that two types of immune cells — T helper 17 (Th17) cells and B cells — can work together to destroy solid tumors and help prevent them from returning. This partnership was unexpected, as most immunotherapies have focused on T cells alone. But in this study, Th17 cells only succeeded in protecting against cancer when B cells were present. These B cells didn’t just help — they produced powerful tumor-fighting antibodies that continued to protect the body long after treatment.
Why does this matter for patients with advanced or treatment-resistant cancer? This research points to a new path in immunotherapy: using the body’s own cells, not just to attack tumors, but to create lasting protection. It could lead to therapies that are more effective for cancers that haven’t responded to current treatments. And because the therapy worked even after the cancer came back in the study’s models, it holds special hope for preventing recurrence — a critical concern for anyone living with stage 4 cancer. A version of this therapy is already being developed for human use. (Source: Emory University Winship Cancer Institute)
