Mouse monoclonal antibodies recognizing cell surface molecules on tumour cells from a patient with a T-cell chronic lymphatic leukaemia (T-CLL) have been produced. Three different types of idiotype-like cell surface structures were identified. One molecule had a relative molecular weight (Mr) of 90,000 under non-reduced conditions and of 42,000 upon(More)
The expression of seven different alpha and beta gene segments of the T cell receptor on normal human CD4+ and CD8+ T lymphocytes, respectively, was examined using V gene-specific monoclonal antibodies. We found a statistically significant (p less than 0.001) bias of the expression of four V gene products towards the CD4+ subpopulation. In every individual(More)
We compared T cell receptor (TCR) V-segment frequencies in human leukocyte antigen (HLA) identical siblings to sibling pairs who differ at one or both HLA haplotypes using four V beta-specific and one V alpha-specific monoclonal antibody. In every one of nine families HLA-identical sibs had the most similar patterns of V-segment frequencies in their(More)
To determine the extent of V-gene heterogeneity of blood T lymphocytes in patients suffering from Myasthenia Gravis (MG), we used eight recently available monoclonal antibodies (MoAb), directed against different V alpha and V beta gene products of the variable part of the T-cell receptor (TCR), covering approximately 25% of the alpha/beta T cells in normal(More)
The alpha/beta T cell receptor (TcR) V gene usage of bronchoalveolar lavage (BAL) lymphocytes and peripheral blood lymphocytes (PBL) from 11 sarcoidosis patients and 4 healthy controls was investigated, using eight alpha/beta TcR V gene product-specific monoclonal antibodies (mAb). Twenty-seven percent (3/11) of the sarcoidosis patients had a highly(More)
Certain T cell antigen receptor V gene products in man have been shown by us and others to display a reproducible bias for preferential expression in CD4+ or CD8+ T cell subsets. In order to investigate whether such a skewed representation of V gene segments is also present at the J gene segment level, we tested the relative J beta gene usage by V beta 5.1(More)
We have previously analysed the T-cell receptor (TCR) V-gene usage in peripheral blood T lymphocytes from a group of healthy Scandinavians, and described a biased representation (i.e. a statistically significant higher median representation) for some of the TCR V genes towards the CD4+ subpopulation. In a subsequent study the usage of the same V genes was(More)
The T cell receptor (TCR) variable (V) gene repertoire was analyzed in patients with monoclonal gammopathy of undetermined significance (MGUS) (n = 17), multiple myeloma (MM) stage I (n = 16), MM stages II/III (n = 31) and age-matched controls (n = 27) by immunofluorescence and flow cytometry using a panel of mouse monoclonal antibodies (mAb) (n = 10)(More)
Publicly Verifiable Outsourced Computation (PVC) allows devices with restricted resources to delegate computations to more powerful external servers, and to verify the correctness of results. Whilst beneficial in many situations, this increases the visibility and availability of potentially sensitive data, so we may wish to limit the sets of entities that(More)
