Research suggests that transforming growth factor-β1, derived from B cells, may play a role in limiting the induction phase of autoimmune neuroinflammation. The factor's involvement in various biological processes, including immune response and fibrosis, is also being explored in other contexts, such as cancer, spinal cord injury, and intestinal disease. The exact mechanisms and effects of transforming growth factor-β1 are still being studied, with potential implications for therapeutic targets.
