The CD123 protein, also known as the Interleukin-3 receptor subunit alpha (IL-3RA) or CD123, is a crucial component of the interleukin-3 (IL-3) receptor complex and belongs to the Type I cytokine receptor family, specifically the Class 5 subfamily. CD123 serves as the high-affinity receptor for IL-3, forming a heterodimeric receptor complex with the β chain (CSF2RB). This protein mediates the stimulatory effects of IL-3 on the proliferation and differentiation of various hematopoietic cells, including pluripotent hematopoietic stem cells and lineage-committed cells. CD123 is expressed on normal plasmacytoid dendritic cells, basophils, monocytes, and eosinophils, and is overexpressed in various hematologic malignancies. In clinical research, the expression of CD123 is associated with chemotherapy resistance and high-risk genetic alterations in certain leukemias, such as acute myeloid leukemia (AML).
Flow cytometric analysis of Human CD123 expression on human PBMC (human peripheral blood mononuclear cell). Human PBMC were stained with Phycoerythrin Mouse IgG2a, κ Isotype Control (Black line histogram) and SDT PE Mouse Anti-Human CD123 Antibody (Red line histogram) at 0.25 μg/test, cells without incubation with primary antibody and secondary antibody (Blue line histogram) was used as unlabelled control. Flow cytometry and data analysis were performed using BD FACSymphony™ A1 and FlowJo™ software.
