Cell therapy with antigen-specific T cells holds promise for various diseases including cancer and viral infections. The powerful enrichment procedure based on major histocompatibility complex (MHC)-tetramers, however, is of limited applicability so far. Therefore, the recently developed cell surface affinity matrix technology that allows direct(More)
Melanoma and renal cell carcinoma (RCC) are considered to be the most immunogenic tumors in humans. To generate conditions to induce primary T-cell responses against RCC and to allow further expansion of tumor-specific cytotoxic T lymphocytes (CTL) for adoptive transfer, peripheral blood mononuclear cells from RCC patients were stimulated with primary(More)
Cathepsin K is a lysosomal cysteine proteinase (LCP) predominantly expressed in osteoclasts. This study was conducted to evaluate the improtance of human cathepsin K for osteoclastic bone resorption relative to that of other LCPs. To accomplish this, we quantitatively determined the expression levels of major LCPs (cathepsins B, K, L, and S) in human(More)
It has been shown that after allogeneic peripheral blood stem cell transplantation (PBSCT), donor T cells can induce potent graft-versus-tumor (GVT) effects in hematologic malignancies and possibly solid tumors such as renal cell carcinoma. Two patients (27 and 30 years old) with metastatic melanoma received allogeneic PBSCT from an HLA-identical sibling(More)
Human calcitonin (hCT) has been reported to have a less hypocalcemizing effect on rats and to have a lower binding affinity for the receptor of mouse osteoclasts than salmon CT(sCT). In this study we comparatively examined the effect of hCT and sCT on osteoclastic boneresorbing activity of unfractionated cells obtained from human giant cell tumor of bone(More)
