CD25
Use
CD25 is the IL-2 receptor alpha chain (IL2RA) present on activated T-cells. The receptor is known to be upregulated in conditions like EBV-transformed B-cells, Hairy cell leukemia, and systemic mastocytosis. Clinically, CD25 expression is significant as it is also observed in inflammatory and malignant conditions that increase IL2 uptake, such as lymphoid neoplasms, autoimmune disorders, and allograft rejection. This provides insight into disease activity and potential therapeutic targets.
