Recombinant interleukin (IL)-15, derived from a simian kidney epithelial cell line, is a chemoattractant for human blood T lymphocytes judged by its ability to increase the proportion of cells in polarized morphology, to stimulate invasion of collagen gels containing IL-15, and to increase the proportion of locomotor cells observed by time-lapse videorecording. The ability of lymphocytes to respond was partly, but not completely, inhibited by pretreatment with anti-IL-2 receptor beta-chain. The activity of IL-15 was completely abolished by preincubation with aIL-15 but unaffected by preincubation with aIL-2. No response of monocytes, neutrophils, or B lymphocytes to IL-15 was observed.
从猴肾上皮细胞系衍生而来的重组白细胞介素(IL)-15,通过以下能力判断,它是人类血液T淋巴细胞的化学引诱剂:增加呈极化形态的细胞比例、刺激含有IL-15的胶原凝胶的侵袭,以及通过延时录像观察增加运动细胞的比例。淋巴细胞的反应能力部分但并非完全受到抗IL-2受体β链预处理的抑制。IL-15的活性通过与抗IL-15预孵育而完全消除,但不受与抗IL-2预孵育的影响。未观察到单核细胞、中性粒细胞或B淋巴细胞对IL-15有反应。
