Immunology at Biogen is focused on exploring the immunobiology underlying autoimmune, inflammatory and fibrotic disease. Our goal is to discover and characterize molecules and pathways that can be targeted to develop biologic and small molecule therapeutics. Research in the department focuses on exploring the role of molecules, pathways and cell types in mediating pathological processes, developing novel target discovery models, elucidating mechanisms of disease and developing innovative biomarker strategies for disease and drug activity. Biology is explored from the molecular to the organismal level using state-of-the-art experimental approaches, including proteomics, chemoproteomics and high-content systems approaches.
