Distant lymph nodes can compensate for resected tumor-draining lymph nodes to sustain anti-cancer immunity during immunotherapy.
- Why it matters: Understanding how immune responses persist after lymph node removal is crucial because tumor-draining lymph nodes are key sites for initiating anti-cancer immunity, and their removal is common in cancer treatment.
- What they did: The study examined melanoma patients and mouse models, showing that soluble tumor antigen is rerouted to distant lymph nodes, where it is presented to T cells, supporting ongoing immune responses after tumor-draining lymph node removal.
- The result: Distant lymph nodes' antigen acquisition enables sustained systemic anti-cancer immunity and enhances immunotherapy responses, especially when targeted with locoregional immune checkpoint blockade.
