    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: Recombinant galectin 8 (rGal 8), produced in host Escherichia coli, exerts hemagglutinating activity, neutrophil adhesion inducing activity, integrin αM-binding activity, proMMP-9 binding activity, active form MMP-9 production promoting activity, superoxide production promoting activity, apoptosis inducing activity for a particular cell, suppressive or inhibitory activity against the metastasis/invasion of tumor cells, etc. In the rGal 8, 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.

    摘要: It has been disclosed that Galectin 9, which is a physiologically active substance acting as a lectin, is expressed in various cells and a correlationship is observed between the expression level of galectin 9 and the metastatic ability of tumors. Therefore, it is presumed that galectin 9 would relate to various physiological phenomena. Thus, a substance allowing the control of galectin 9 production and release is expected as exerting an activity of inducing antitumor and/or anti-inflammatory actions, etc. Therefore, it is required to reveal the same. It has been found that a factor inducing the production and release of galectin 9, “galectin 9-inducing factor”, is contained in a certain solubilized tumor cell membrane fraction. This factor can be obtained as a concanavalin A-adsorbed fraction and as a concentrated active fraction by fractionation with an ion exchange column packed with Resource Q®, a hydroxyapatite column, etc. Assay reagents, drugs, assays, etc. can be developed by using the galectin 9-inducing activity of this factor.
