AI Summary (NQ-processed)
A research team from Chiba University and Fudan University has elucidated using spatial transcriptomics that a 'Danger Zone' exists within gastric cancer tissue, where CCDC80-positive fibroblasts sequester and suppress immune cells. These results are expected to contribute to predicting the therapeutic efficacy of immunotherapy and developing new treatment strategies.

Frequently Asked Questions
- Q: Why is immunotherapy often ineffective for gastric cancer?
- A: The presence of a 'danger zone' in the tumor tissue, where fibroblasts sequester and suppress immune cells, is a key factor.
- Q: What are CCDC80-positive fibroblasts?
- A: They are a group of cells that accumulate in the danger zone of gastric cancer tissue, isolating immune cells and inhibiting their function.
- Q: How does the AI model contribute to gastric cancer diagnosis?
- A: It predicts the risk of progression using H&E images, supporting decisions on immunotherapy response and prognosis.
