Interleukin 2 (IL-2) is a pleiotropic cytokine produced primarily by mitogen- or antigen-activated T lymphocytes. Human IL-2 (also known as T-cell growth factor) is produced by T-cells in response to antigenic or mitogenic stimulation. IL-2 is a potent lymphoid cell growth factor which exerts its biological activity primarily on T cells promoting proliferation and maturation.IL-2 has been found to stimulate growth and differentiation of B cells, NK cells, LAK cells, monocytes, and oligodendocytes. IL-2 is involved in treatment of cancers such as melanoma and renal cell cancer. It plays a key role in promoting the clonal expansion of antigen-specific T cells. In addition, IL-2 has also been shown to mediate multiple immune responses on a variety of cell types.
白介素-2(Interleukin-2,IL-2)是輔助型T淋巴細胞(TH)活化產(chǎn)生的細胞因子[1-2]。IL-2具有雙重調(diào)控免疫應(yīng)變的能力,可有效誘導(dǎo)細胞免疫和體液免疫應(yīng)答。 白介素（IL-2)的主要生理作用是刺激和維持T細胞的分化增殖。IL-2有關(guān)腫瘤的生物學(xué)活性包括：1.刺激自然殺傷(NK)細胞的增殖和活化，并增強其活性。2.誘導(dǎo)細胞毒性淋巴細胞，增強其溶細胞活性。3.誘導(dǎo)淋巴因子活化殺傷(LAK)細胞。LAK細胞具有廣譜的抗腫瘤活性，可以溶解多種腫瘤細胞。IL-2不僅是產(chǎn)生LAK細胞的必需淋巴因子，而且在它的存在下還能維持LAK細胞的增殖和長期生長，因此，在臨床抗腫瘤治療時往往把IL-2和LAK細胞同時給予，這就是惡性腫瘤的過繼免疫性治療(adoptiveimmunetherapy，AIT)。4.刺激腫瘤浸潤淋巴細胞(TIL)的增生并增強其活性。動物實驗證明，TIL較LAK細胞的抗腫瘤活性高50～100倍。5.不僅能促進T細胞增殖，且對細胞有促增殖和促分化作用。在腫瘤治療的動物模型中已證明，當(dāng)T細胞中介抗瘤反應(yīng)強烈時，很低量的IL-2已足以激化抗瘤作用；但當(dāng)T細胞中介的抗瘤反應(yīng)很弱時，則需要很高劑量的IL-2。低劑量可以顯著地刺激T細胞，而激活NK及LAK細胞則要求很大劑量。因IL-2不能直接抗癌，用藥目的是最大限度地興奮免疫機制，以加強抗癌作用。以前常用的IL-2和LAK細胞聯(lián)合應(yīng)用治療惡性腫瘤，現(xiàn)已不再推薦，而代之以IL-2與腫瘤浸潤淋巴細胞(TIL)聯(lián)合療法。6.rhIL-11為177個氨基酸組成的活性蛋白質(zhì)。其編碼基因位于19號染色體長臂13區(qū)。作用于巨核細胞系較晚期階段的巨核細胞水平，促進巨核細胞的增殖及成熟，并促進血小板的產(chǎn)生。IL-11雖無巨核細胞集落刺激因子(Meg-CSF)的活性，但有巨核細胞增殖因子的活性，與GM-CSF及IL-3協(xié)同作用，可使CFU-MegDNA量增多。 |
