摘要:: Unstimulated PBL were examined for expression of IL-2R subunits, IL-2Rp55 and IL-2Rp75, by two-color flow cytometric analyses using mAb. NKH-1+ non-T non-B cells expressed IL-2Rp75 but not IL-2Rp55, and the IL-2Rp75 sites on purified NKH-1+ cells were determined to be 1630 sites/cell by binding of 125I-labeled TU27 mAb specific for IL-2Rp75. In the CD4+ T cell population, IL-2Rp55+ cells were significantly detected, but little or marginally of the IL-2Rp75+ cells. However, IL-2Rp75+ cells were significantly detected, but little of the IL-2Rp55+ cells in the CD8+ T cell population. The IL-2Rp75 sites on CD8+ T cells were estimated at approximate 180-410 sites/cell. In the CD4+ T cells, expression of IL-2Rp75 as well as IL-2Rp55 was induced by stimulation with PHA. IL-2Rp75+ cells, but not IL-2Rp55+ cells, were also detected in the CD14+ monocyte population. In the CD20+ B cell population, a small number of IL-2Rp55+ cells was detected, but little of the IL-2Rp75+ cells.
