    • Galectin 9 exerts various functions depending on its localizations. On the other hand, galectin 9 is expected as participating in various biological functions. Thus, it has been required to clarify the detailed biological activities of galectin 9 and develop galectin 9-related techniques including development of drugs. Human galectin 9 shows a cytotoxic activity and an apoptosis-inducing activity on tumor cells but shows neither cytotoxic activity nor apoptosis-inducing activity on normal cells. Therefore, it is possible to employ galectin 9 proteins, galectin 9 agonists, galectin 9 antagonists, anti-galectin 9 binding protein antibodies, anti-galectin 9 binding sugar chain antibodies, galectin 9-producing, releasing or inducing substances, etc. as antitumor, antiallergic, immunosuppressive agents, drugs for autoimmune diseases, anti-inflammatory agents and active ingredients for adrenocortical steroid hormone alternatives.
    • Galectin 9根据其定位具有各种功能。 另一方面,半乳凝素9预期参与各种生物学功能。 因此,需要阐明半乳凝素9的详细生物学活性,并开发包含药物开发的半乳凝素9相关技术。 人半乳凝素9显示对肿瘤细胞的细胞毒活性和细胞凋亡诱导活性,但对正常细胞无细胞毒性活性或细胞凋亡诱导活性。 因此,可以使用半乳凝素9蛋白,半乳凝素9激动剂,半乳凝素9拮抗剂,抗半乳凝素9结合蛋白抗体,抗半乳凝素9结合糖链抗体,半乳凝素-9产生,释放或诱导物质等作为抗肿瘤剂 ,抗过敏药,免疫抑制剂,自身免疫性疾病药物,抗炎药和肾上腺皮质激素替代物的活性成分。

    • Galectin 9, which is an immune function-controlling factor belonging to a new class that is different from known cytokines and is expected to be used as a therapeutic drug for various immune-related diseases such as an autoimmune disease, has disadvantages (such as high sensitivity to protease and poor solubility) to be solved in developing therapeutic drugs. Therefore, there is a need to overcome these disadvantages. Chemically modified galectin 9, prepared by conjugating a polymer (for example, poly(ethylene glycol: PEG) to galectin 9, in particular, stabilized galectin 9, is verified to exert higher solubility with improvements in pharmacodynamics and pharmacokinetics (for example, prolongation of action potential duration, such as prolongation of blood half-life and others) and in suppression of hemagglutination and thus has excellent characteristics as a drug.
    • 作为属于与已知细胞因子不同的新类别的免疫功能调节因子的半乳凝素9预期被用作各种免疫相关疾病如自身免疫性疾病的治疗药物,具有缺点(例如高 对蛋白酶的敏感性和溶解性差)在开发治疗药物中得到解决。 因此,需要克服这些缺点。 验证通过将聚合物(例如,聚乙二醇:PEG)与半乳聚糖9(特别是稳定的半乳聚糖9)结合而制备的化学修饰的半乳凝素9,其药效学和药代动力学的改善(例如, 动作电位持续时间,如血液半衰期延长等),抑制血细胞凝集,作为药物具有优异的特性。

    • It is suggested that recombinant galectin 9 (rGal 9), produced in host Escherichia coli, exhibits an immune system-mediated action and a direct action on tumor cells (i.e., activity of inducing the intercellular adhesion and apoptosis of the tumor cells), thereby potent in inducing the inhibition of cancer metastasis and reduction. Moreover, the rGal 9 exerts no efficacy on non-activated lymphocytes but can induce apoptosis in activated T cells, in particular, CD4-positive T cells causing an excessive immune response. The rGal 9 has a further potent apoptosis-inducing property on synovial cells participating in joint deformation in rheumatism, etc. In the rGal 9, however, a link domain linking two CRDs is highly susceptible to protease and, therefore, is very easily digestible with the enzyme, thereby losing the above activities. Thus, there is a need for a more stabilized molecule in view of further studies. Modification of the link domain linking two CRDs in galectin 9 provides a modified molecule having an elevated activity without any undesirable effects on the above activities.
