摘要: Cancer cells modulate the recruitment and function of inflammatory to create an immunosuppressive microenvironment that favors tumor growth metastasis. However, tumor-derived regulatory programs promote intratumoral immunosuppression remain poorly defined. Here, we show in a KrasLA1/+p53R172HΔg/+-based mouse model bone morphogenetic protein-4 (BMP4) augments expression T cell co-inhibitory receptor ligand PD-L1 mesenchymal subset lung cancer cells, leading profound CD8+ cell-mediated immunosuppression, producing We previously reported this BMP4 functions as pro-tumorigenic factor regulated by miR-200 via GATA4/6. Thus, BMP4-mediated is part larger miR-200-directed gene program tumors promotes progression, which could have important implications for treatment.
