    • The present invention relates to an agent for differentiating hematopoietic stem cells into natural killer cells and a method for the differentiation, more precisely an agent for differentiating hematopoietic stem cells into natural killer cells comprising YC-I [3-(5′-hydroxymethyl-2′-furyl)-1-benzylindazole] or IL-21 (Interleukin-21) as an active ingredient and a method for differentiating hematopoietic stem cells into natural killer cells using the same. The YC-I and IL-21 regulate the differentiation of hematopoietic stem cells into natural killer cells and increase the killing activity of NK cells. Therefore, the agent for NK cell differentiation of the present invention can be effectively used for cell therapy for the treatment of cancer by regulating the differentiation of hematopoietic stem cells into natural killer cells having tumor cell killing activity.
    • 本发明涉及用于将造血干细胞分化为天然杀伤细胞的试剂和分化方法,更准确地说,用于将造血干细胞分化成包含YC-1 [3-(5'-羟甲基-2 糠基)-1-苄基吲唑]或IL-21(白细胞介素-21)作为活性成分,以及使用其将造血干细胞分化为天然杀伤细胞的方法。 YC-1和IL-21调节造血干细胞分化为自然杀伤细胞,增加NK细胞的杀伤活性。 因此,通过调节造血干细胞分化为具有肿瘤细胞杀伤活性的天然杀伤细胞,本发明的NK细胞分化剂可以有效地用于治疗癌症的细胞治疗。

    • The present invention relates to a method for activating natural killer cells (NK cells), and more particularly, to a method for enhancing the cytotoxicity of natural killer cells by inducing the overexpression of suppressor of cytokine signaling 2 (SOCS2) which is a protein involved in cell-signaling pathways in natural killer cells. The inventors of the present invention observed that when natural killer cells were treated with IL-15, a cytokine involved in natural killer cell differentiation, the expression of SOCS2 increased and the expression of proline-rich tyrosine kinase 2 (Pyk2) was inhibited by the SOCS2, the expression of which increased. In addition, when Pyk2 was overexpressed, the ability to produce IFN-γ and the ability to kill tumor cells of natural killer cells decreased. Therefore, SOCS2 can be used for activating natural killer cells and the natural killer cells activated by the method can be used for the prevention or treatment of cancer.
    • 本发明涉及一种用于激活天然杀伤细胞(NK细胞)的方法,更具体地说,涉及通过诱导涉及蛋白质的细胞因子信号传导抑制剂(SOCS2)的过表达来提高天然杀伤细胞的细胞毒性的方法 在自然杀伤细胞的细胞信号通路中。 本发明的发明人观察到,当用IL-15(参与自然杀伤细胞分化的细胞因子)处理天然杀伤细胞时,SOCS2的表达增加,富含脯氨酸的酪氨酸激酶2(Pyk2)的表达受到抑制 SOCS2,其表达增加。 此外,当Pyk2过表达时,产生IFN-γ的能力和杀死自然杀伤细胞的肿瘤细胞的能力下降。 因此,SOCS2可用于激活自然杀伤细胞,并且通过该方法活化的天然杀伤细胞可用于预防或治疗癌症。

    • The present invention relates to a method for efficiently proliferating and differentiating natural killer cells (NK cells) from umbilical cord blood, more precisely a method for efficiently proliferating and differentiating natural killer cells from umbilical cord blood comprising the following steps: 1) preparing CD3 negative cells by eliminating CD3 positive T-cells from umbilical cord blood derived mononuclear cells; and 2) culturing the CD3 negative cells after treating various cytokines thereto. The present invention is advantageous in obtaining high purity NK cells in a short period of time by inducing NK cells from CD3 negative cells, compared with the conventional method inducing NK cells from haematopoietic stem cells, and in promoting NK cell proliferation and differentiation by treating different cytokines together, for example by the co-treatment of IL-15 and IL-21. That is, the method of the present invention can induce NK cells with increased anti-cancer cytotoxicity, so that it can be effectively used for anti-cancer cell therapy.
    • 本发明涉及一种有效增殖和分化脐带血自然杀伤细胞(NK细胞)的方法,更确切地说,一种有效增殖和分化脐带血自然杀伤细胞的方法,包括以下步骤:1)制备CD3阴性 通过从脐带血衍生的单核细胞中消除CD3阳性T细胞的细胞; 和2)在处理各种细胞因子后培养CD3阴性细胞。 本发明与从造血干细胞诱导NK细胞的常规方法相比,通过诱导CD3阴性细胞的NK细胞在短时间内获得高纯度NK细胞是有利的,并且通过治疗不同的方法促进NK细胞增殖和分化 细胞因子在一起,例如通过共同治疗IL-15和IL-21。 也就是说,本发明的方法可以诱导具有增加的抗癌细胞毒性的NK细胞,从而可以有效地用于抗癌细胞治疗。
