Abstract: The present invention relates to immunogenic peptides derived from human prostate cancer antigen (PSA-derived peptides) and their use as vaccines to treat or prevent prostate cancer. The invention is also related to dendritic cells from a patient having prostate cancer, which dendritic cells have been exposed to one or more PSA-derived peptides, and their use to treat or prevent prostate cancer in the patient. The invention is also directed to T-cells from a patient which cells are specific for PSA-activated peptide(s), and their uses to treat or prevent prostate cancer.

Abstract: Disclosed is a method of inducing a reduced immune response to a transplant in a recipient by treating said recipient with an amount of fibroblasts or a supernatant from a fibroblast culture effective to reduce or inhibit host rejection of the transplant. The fibroblasts or a supernatant from a fibroblast culture can be administered before, at the same time as, or after the transplant. This method is effective in reducing an immune response to a transplant without compromising the immune response to other foreign antigens. Also disclosed is a method of inducing a reduced immune response against a host by foreign tissue, i.e., graft versus host disease.

Abstract: A nucleic acid molecule comprising at least one nucleotide sequence encoding SEQ ID NO: 14, 15, 19, 41, or a sequence that is at least about 95% identical thereto; a composition comprising same and a method of administering same to induce an immune response; a polypeptide consisting of SEQ ID NO: 14, 15, 19, 41, or a sequence that is at least about 95% identical thereto; a composition comprising same and a method of administering same to induce an immune response; a composition comprising APC, which have been exposed to the polypeptide, and a method of administering same to treat prostate cancer; a composition comprising T-cells, which are specific for an epitope in a polypeptide consisting of SEQ ID NO: 14, 15, 19, or 41 and a method of administering same to treat prostate cancer; a composition comprising an anti-idiotypic antibody having an internal image of an epitope of a polypeptide consisting of SEQ ID NO: 14, 15, 19, or 41 and a method of administering same to treat prostate cancer; and an immortal B-c

Abstract: A method of reducing an immune response to a transplant in a recipient by treating said recipient with an amount of mesenchymal stem cells effective to reduce or inhibit host rejection of the transplant. The mesenchymal stem cells can be administered before, at the same time as, or after the transplant. Also disclosed is a method of inducing a reduced immune response against a host by foreign tissue, i.e., graft versus host disease, by treatment with mesenchymal stem cells.
