Sub-types of HLA-B27 were detected by cytotoxic T lymphocytes (CTL) generated between HLA-A, -B- and -C-identical B27-positive individuals. We now report the specificity of six independent CTL's generated by mixed lymphocyte culture (MLC) of HLA-A, -B and -C serologically identical B27-positive responder and stimulator cells. Three CTL's recognize one(More)
Three HLA-B7-specific cytotoxic T lymphocyte (CTL) clones are described. Their fine specificity is examined by extensive panel and family studies. Four CTL-defined subtypes of HLA-B7 could be found: HLA-B7.1, -B7.2, -B7.3, and -B7.4. Biochemical evidence was obtained in one-dimension isoelectric focusing for only two subtypes. The estimated subtype(More)
With the aid of alloreactive cytotoxic T lymphocytes, three subtypes of HLA-B27 can be defined: B27W, B27K, and B27C (non-B27W and non-B27K). The B27C subtype can be distinguished by 1D-IEF, is not recognized by B27W- or B27K-restricted influenza-A-specific cytotoxic T lymphocytes, and is prevalent in Oriental populations. Preliminary data indicate that the(More)
When human peripheral blood lymphocytes (PBL) are cultured in the presence of irradiated allogeneic lymphocytes, the resulting mixed lymphocyte reaction (MLR) leads to the secretion into the supernatant of substantial amounts of IgM and IgG, derived from nonirradiated responder B lymphocytes. Our data indicate that stimulation to Ig production by responder(More)
Introduction Interconnects are an important cost driver in advanced 3D chip packaging. This holds for Through Silicon Vias (TSV) for chip stacking, but also for other integrated Sitechnology. Especially in applications with a low number (<100 mm) of relatively large (10-20 μm diameter), high aspect ratio (1:5-1:20) interconnects, conventional wafer level(More)
