Used in research and development for autoimmune diseases and inflammatory conditions. Targets the IL-7 receptor alpha (CD127) to modulate T-cell activity, particularly in diseases like multiple sclerosis, rheumatoid arthritis, and type 1 diabetes. Investigated for its ability to suppress pathogenic T-cell responses while preserving regulatory T cells, offering potential for selective immune modulation. Also serves as a reference standard in bioassays and antibody development programs.
