Barbara A. Osborne

Barbara A. Osborne is a Professor in the Department of Veterinary and Animal Sciences at the University of Massachusetts Amherst, affiliated with the College of Natural Sciences. Her laboratory conducts cutting-edge research on CD4+ T lymphocyte differentiation and function, with a strong focus on Notch signaling pathways and their role in autoimmune diseases.

Education:

• Ph.D., Stanford University, 1979
• Postdoctoral Training, National Institutes of Health

Her research investigates how Notch proteins regulate the development of T-helper 1 (Th1) and T-helper 17 (Th17) cells, both of which are implicated in autoimmune conditions such as experimental autoimmune encephalomyelitis (EAE), a model for multiple sclerosis. By utilizing gamma-secretase inhibitors (GSIs), her lab has demonstrated the potential to block EAE progression, suggesting therapeutic applications for MS. Current work explores which specific Notch family member drives disease and whether signaling occurs via canonical or non-canonical pathways. Additionally, her team studies gamma-secretase's broader role in cleaving immune receptors and collaborates with the UMass IALS Center for Bioactive Delivery to develop nanogel-based tools for targeted inhibition of pathogenic T cells.

Barbara A. Osborne collaborates with researchers at UMass, the University of Florida, and LSU Medical School, advancing interdisciplinary approaches to immune modulation. Her work bridges molecular biology, immunology, and translational medicine.
