摘要:
Mouse IgG.sub.1 inducing factor and the DNA that codes for the same were isolated by using a novel genetic technique, and their structures determined by the dideoxy chain termination method. The mouse IgG.sub.1 inducing factor obtained by the method of this invention has activity to improve immune response in living bodies and are hence useful for the treatment and prevention of infectious diseases, AIDS, functional immunodeficiency and the like. This factor, or part of its amino acid sequence, may also be used for the preparation of antibody against the same. In addition, it is possible to use this factor as a model for the synthesis of other polypeptides having similar structures, and for many other purposes.
摘要:
Compositions for cancer or infection treatment via immunopotentiation caused by inhibition of immunosuppressive signal induced by PD-1, PD-L1, or PD-L2 and therapies using them, immunopotentiative substrates included as the active ingredient, screening methods of the substrates for cancer or infection treatment, cell lines used for the screening methods, evaluation methods that select the substrates for cancer treatment, and carcinoma cell transplanted mammals used for the evaluation methods. The compositions of the present invention that inhibits the function of PD-1, PD-L1, or PD-L2 are useful for treatment of cancer or infection.
摘要:
The present invention relates to human, rat and mouse stem cell-derived neuron survival factor polypeptides (SDNSF), a process for producing them, cDNA encoding SDNSF, a vector comprising the cDNA, host cells transformed by the vector, an antibody against SDNSF, pharmaceutical compositions containing SDNSF or the antibody, a method of assaying SDNSF, a reagent for assaying SDNSF, and a screening method using SDNSF. The polypeptides are effective in the survival of nerve cells and neuronal stem cells, therefore, efficacious in treating injury to the central nerve system and cancer.

摘要:
Genes encoding novel proteins named AID (Activation-Induced cytidine Deaminase), that are structurally related to APOBEC-1, an RNA editing enzyme, and have a cytidine deaminase activity similar to APOBEC-1, have been found by preparing cDNA libraries from mouse B cell clone CH12F3-2 (which undergoes class switch recombination from IgM to IgA at an extremely high rate after activation of the cells by stimulation with cytokines), with and without stimulation with cytokines, and performing subtraction cloning using the libraries.

摘要:
The present invention relates to a substance specific to human PD-1 comprising a part that recognizes human PD-1, a part that recognizes a membrane protein in cell membrane of human PD-1-expressing cells, and linkers. Since the substance specific to human PD-1 selectively can recognize human PD-1 and a membrane protein on cell membrane of human PD-1-expressing cells and can transmit inhibitory signal of human PD-1, it is useful for therapy and/or prevention of diseases caused by immunopathy.
