🔬 New cell shields lung cancer from immune attack
Scientists discovered a new cell type that helps protect lung cancers from immune system attacks. This finding was made by researchers at Columbia University while studying fibroblasts in mouse models of lung cancer. The study, published in Nature Immunology on August 11, 2026, revealed that these cells recruit regulatory T cells using CXCL9. This recruitment creates an immunosuppressive environment that allows the tumor to survive. Targeting these fibroblasts or T cells could offer a new strategy against lung cancer. 🔬
