Abstract: The object is to provide a tumor antigen peptide that is specifically presented on a cancer and a cancer stem cell, and a pharmaceutical composition, etc. that is useful for the prevention and/or treatment of a cancer and contains the above peptide as an active ingredient. The above object has been accomplished by providing a BORIS-derived partial peptide belonging to isoform A or C or subfamily 5 or 6, a polynucleotide encoding the peptide, a pharmaceutical composition containing the above as an active ingredient, and an agent for the prevention and/or treatment of a cancer, the agent containing the above as an active ingredient and inducing CTLs.

Abstract: A method has been developed to efficiently proliferate and culture a CTL specific to WT1 peptides under limiting dilution conditions. Utilizing this method, CTLs capable of recognizing both a state where a wildtype WT1 specific peptide is presented by HLA-A*24:02 and a state where a mutant WT1 specific peptide is presented by HLA-A*24:02 have been successfully obtained.

Abstract: The successful identification of epitope peptides specific to adenovirus belonging to subgroup B and epitope peptides exhibiting specificity to all adenoviruses using hexon proteins which exhibit the highest homology among genes of adenoviruses of various subgroups is herein described. The peptides have a function capable of efficiently inducing adenovirus-specific cytotoxic T cells (CTLs). Thus, the peptides disclosed herein find utility as vaccines for active immunization. Furthermore, CTLs induced by such peptides find utility as passive immunotherapeutic agents.

Abstract: The present invention provides HIDE1 as novel monocyte markers. Since HIDE1 are membrane proteins, monocytes can be specifically detected by using antibodies that bind to HIDE1. Further, HIDE1-positive monocytes can also be collected from peripheral blood or the like using a cell sorter, magnet, or such. Monocytes that can be prepared based on the present invention are useful in cell immunotherapy.

Abstract: A search was conducted for functional antibodies that endogenously regulate cytokines, focusing on the relationship between inflammatory diseases and cytokines. Mice were immunized with a human peripheral blood monocyte fraction and the obtained antibodies were examined for a cytokine-regulating effect. As a result, of these antibodies, antibody #33 was confirmed to inhibit the production of numerous typical inflammatory cytokines. When, at the same time, the promoting effect of antibody #33 on IL-10 production was examined, it was revealed that antibody #33 has an effect of accelerating IL-10 production but no activity to induce an excessive IL-10 production. The antigen of this promising antibody was verified to be CD61. Therefore, it is conceivable that when anti-CD61 antibodies are applied to the treatment of inflammatory diseases, they would become pharmaceuticals with both a definite efficacy and a high safety.
