π¬ New cells found that shield lung tumors from immune attack
Scientists have discovered a previously unknown cell type that acts as a bodyguard for lung tumors, shielding them from immune system attacks. This discovery was made by a researcher from Columbia University while studying fibroblasts around solid tumors. The study revealed this distinct CHL1 fibroblast subpopulation exists in lung cancers as of the recent publication. These cells release CXCL9, which attracts regulatory T cells to create an immunosuppressive shield around the cancer. Future therapies could potentially neutralize these cells to unleash the body's natural defenses against the tumor. π¬
