Definitions
- the present invention relates to a mass production method of natural killer cells and the use of the natural killer cells obtained by the method as an anticancer agent.
- Immune response to tumor removal occurs through the complex interaction of immune cells with different functions.
- Immune cells that directly remove tumor cells include natural killer cells (NK cells) and cytotoxic T lymphocytes (CTLs), and present antigens to these effector cells.
- NK cells natural killer cells
- CTLs cytotoxic T lymphocytes
- Cells include dendritic cells (DC) or B cells, and in addition, helper T cells and regulatory T cells that work together to secrete various cytokines (cytokine) do.
- DC dendritic cells
- B cells helper T cells and regulatory T cells that work together to secrete various cytokines (cytokine) do.
- NK cells are a kind of lymphocytes and are distributed in bone marrow, spleen, peripheral lymph nodes and peripheral blood in the human body, and about 10% of lymphocytes are known to be NK cells in peripheral blood (ann Rev Immunol., 24: 257-286, 2006).
- NK cells are positive for CD56 and CD16, but negative for CD3.
- NK cells kill tumor cells or virus-infected cells without restriction to previously exposed stimuli or MHC and do not exhibit receptor rearrangements according to cell clones (Trends Immunol., 22: 633-640, 2001). ).
- NK cells kill cells is associated with the release of cytoplasmic granules, including perforin and granzyme, and processes involving FasL and TRAIL.
- NK cells secrete a variety of cytokines, particularly IFN- ⁇ , INF- ⁇ , GM-CSF and IL-10, and express several receptors on the cell surface, which are responsible for cell adsorption, activation of cell killing capacity, or cell killing. Involved in the suppression of ability.
- NK cells recognize MHC class I molecules through killer immunoglobulin-like receptors (KIR), the majority of which are cell killing inhibitors, and if these inhibitory receptors are not recognized as MHC molecules, cell killing occurs.
- KIR killer immunoglobulin-like receptors
- NK cells The killing ability of these NK cells is used to treat solid cancer using lymphokine activated killer cells (LAK) and tumor infiltration lymphocytes (TIL), or through donor lymphocyte infusion. Occurs during bone marrow transplantation or organ transplantation by performing immunotherapy (Tilden. AB et al, J. Immunol. , 136: 3910-3915, 1986; Bordignon C. et al., Hematologia, 84: 1110-1149, 1999) Applications have been attempted as novel cell therapy to prevent rejection. In addition, defects in the differentiation and activity of NK cells have been associated with breast cancer (Konjevic G. et al., Breast Cancer Res. Treat.
- NK cells in the body in the normal state are in an inactivated state, but since the activated NK cells are actually needed to use the NK cells for treatment, the blood from the normal blood or inactivated patient blood Studies on activating NK cells from the ovary have been actively conducted.
- NK cells have been reported to be effective after administration of allogeneic bone marrow transplantation to blood cancers such as leukemia ( Blood Cells Molecules & Disease , 33: 261-266, 2004). However, clinically definite therapeutic effects on NK cells have not been demonstrated for non-hematologic solid cancers. Although NK cells have been reported to interfere with tumor engraftment prior to tumor development ( Cancer Immunol. Immunother.
- NK cells are administered to inhibit the growth of breast cancer cells, but it is unclear whether the effect is caused by NK cells ( Breast Cancer Res. Treat. , 104 (3): 267-275, 2007).
- NK cells account for 10-15% of lymphocytes in the blood, and in cancer patients, the number, differentiation, and function of NK cells are often reduced, making it difficult to obtain sufficient cell numbers. Therefore, it is urgently required to secure a large amount of NK cells through proliferation or differentiation of NK cells.
- NK cells are known to be derived from hematopoietic stem cells (HSCs) of bone marrow.
- HSCs hematopoietic stem cells
- In vitro methods for separating hematopoietic stem cells from cord blood and treating them with appropriate cytokines and incubating them with NK cells have been reported (Galy et al., Immunity 3: 459-473, 1995; Mrozek E, et al., Blood 87: 2632-2640, 1996; Sivori, S. et al., Eur J Immunol . 33: 3439-3447, 2003; B. Grzywacz, et al., Blood 108: 3824-3833, 2006) .
- Flt-3L, IL-7, SCF, and IL-15 may be added to CD34 + HSC to differentiate into CD3 - CD56 + NK cells after 5 weeks of culture.
- this differentiation method has difficulties in actual clinical application such as it is difficult to obtain a sufficient amount of cells for treatment and requires time and cost to differentiate.
- ⁇ c form of the receptor is a receptor of IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21, of which IL-2 promotes proliferation and activation of mature NK cells. It has been reported to have a function (Shibuya, A. et al., Blood 85, 3538-3546, 1995).
- IL-2R IL-2 receptor chains are known to be involved in forming receptors of IL-15.
- IL-15 is involved in NK cell differentiation, which is deficient in NK cells in mice lacking interferon-regulating factor-1 (IRF-1), a transcription factor required for IL-15 production ( Kouetsu et al., Nature 391, 700-703, 1998), found that no NK cells were found in mice lacking IL-15 or IL-15Ra. It has been reported that IL-15 directly promotes the growth and differentiation of NK cells through IL-15 receptors expressed in NK cells (MrozekE et al., Blood 87, 2632-2640,1996).
- IRF-1 interferon-regulating factor-1
- IL-21 is a cytokine secreted by activated CD4 + T cells (Nature, 5: 688-697, 2005), and receptors of IL-21 (IL-21R) are dendritic cells, NK cells, T cells and B It is expressed in lymphocytes such as cells (Rayna Takaki, et al., J. Immonol 175: 2167-2173, 2005).
- IL-21 is structurally very similar to IL-2 and IL-15, and IL-21R shares a chain with IL-2R, IL-15, IL-7R and IL-4R (Asao et al., J.) . Immunol , 167: 1-5, 2001).
- IL-21 has been reported to induce maturation of NK cell precursors from bone marrow (Parrish-Novak, et al., Nature, 408: 57-63, 2000), in particular with cytokine production and apoptosis of NK cells.
- the same effector functions have been reported to increase (M. Strengell, et al., J Immunol, 170: 5464-5469, 2003; J. Brady, et al., J Immunol , 172: 2048-2058, 2004), it has also been reported to promote anticancer responses of the intrinsic, adaptive immune system by increasing the effector function of CD8 + T cells (Rayna Takaki, et al., J Immunol 175: 2167-2173, 2005; A.
- NK cells have a problem that mass proliferation and culture are not performed properly in vitro, and thus, there has been a demand for the development of a technology for amplifying and culturing NK cells at a practically useful level. It does not reach the level applicable to the clinic.
