Myeloid cells can promote or limit tumor outgrowth but remain poorly understood. In a study published in Immunity, the Pittet lab at the MGH Center for Systems Biology and the Klein lab at Harvard Medical School teamed up to map myeloid cells at the single cell level in human and mouse lung cancer. They made the following findings: 1) Consistent complexity: the same tumor myeloid populations are repeatedly found across patients, indicating that the myeloid microenvironment within lung tumors is stereotyped. 2) Conservation across species: many myeloid populations are highly conserved across patients and mice, suggesting that studying myeloid cells in mice can help understand the human disease. 3) New therapeutic targets: the map of tumors’ myeloid populations identified in this study points to new targets for cancer immunotherapy.
The MGH Center for Systems Biology (CSB) was established as one of the five thematic interdisciplinary Centers at MGH. It is home to over 200 researchers in 12 PI groups. The mission of the Center is to analyze at a systems level how biological molecules, proteins and cells interact in both healthy and diseased states.
Through a multidisciplinary approach that combines clinical insight with powerful technologies, CSB faculty pursue systems-level research that is at once fundamental, and yet immediately linked to the diagnosis and treatment of human disease. While these approaches are generalizable to many diseases, the Center has particular strengths in complex human conditions such as cancer, cardiovascular disease, diabetes, autoimmune disease, and renal disease. This goal is enabled by particular faculty expertise in genomics, chemical biology, physiology, bioimaging, and nanotechnology.
