摘要:
The present invention relates to a method for treatment of cancer, which comprises the following steps (A) and (B): (A) applying a treatment which induces the reduction in lymphocytes to a patient; and (B), subsequent to step (A), administering lymphocytes to the patient promptly. The present invention also relates to a cancer therapeutic agent and a cancer treatment kit for use in the method. When the method is used as an immunoreconstructive therapy, the decrease in immunologic competence which may be caused by the reduction in lymphocytes can be avoided and, therefore, the risk of the occurrence of an infectious disease can be decreased.

Disclosed is a method for enhancing the function of a T cell, which is characterized by inhibiting the expression of programmed death-1 ligand 1 (PD-L1) and/or programmed death-1 ligand 2 (PD-L2) in the T cell. Also disclosed is a function-enhanced T cell which is produced by the function enhancement method. Further disclosed is a therapeutic agent comprising the function-enhanced T cell. The T cell can enhance an immune response to cancer, and is useful in an immunotherapy effective for cancer and the treatment or prevention of infectious diseases and autoimmune diseases.

Disclosed are: a cell capable of expressing an exogenous GITRL or an exogenous GITRL derivative; a method for producing the cell; a therapeutic or prophylactic agent comprising the cell as an active ingredient; use of the cell in the manufacture of a therapeutic or prophylactic agent; a method comprising a step of administering the cell to a subject; a viral vector carrying a gene encoding a GITRL or a GITRL derivative; a therapeutic or prophylactic agent comprising the viral vector as an active ingredient; use of the viral vector in the manufacture of a therapeutic or prophylactic agent; and a method comprising a step of administering the viral vector to a subject.

Disclosed is a cell which can express a non-natural oligomeric protein, which has, introduced therein, a gene encoding an exogenous polypeptide corresponding to at least one endogenous polypeptide constituting a natural oligomeric protein, and in which the expression of the endogenous polypeptide is inhibited.

摘要:
A vaccine preparation for treating cancer includes a complex of a hydrophobized polysaccharide and at least one synthetic long peptide derived from a tumor-specific antigenic protein and/or a pathogen-derived antigenic protein. The at least one synthetic long peptide contains at least one CD8+ cytotoxic T-cell recognition epitope and at least one CD4+ helper T-cell recognition epitope. The complex is simultaneously administered to the patient with at least one immunopotentiating agent.

The present invention relates to a DNA vaccine for developing tumor-specific immunity. Specifically, the invention relates to a DNA vaccine comprising antigens recognized by CD4+ helper T cells and CD8+ cytotoxic T cells, respectively. Preferably, the antigen recognized by CD4+ helper T cells is a molecule identified by the SEREX method and that recognized by CD8+ cytotoxic T cells is a tumor-specific antigen, tumor-associated antigen or cell-associated antigen. Furthermore, so that the antigens recognized by CD4+ helper T cells and CD8+ CTL are expressed and presented on the same cell, the expression vectors preferably are immobilized on the same gold particle and administered into the cell by gene gun; however, this invention is not restricted thereto. The vaccine can also be used as a pharmaceutical agent.
摘要:
This invention provides a method for preparing Langerhans cells from CD14-positive cells, which are human peripheral blood mononuclear cells. This method comprises culturing human peripheral blood mononuclear cells in the presence of Notch ligand, GM-CSF, and TGF-β.
