Decreased T-cell receptor excision circles in cutaneous T-cell lymphoma.
PURPOSE The T cell repertoire in patients with advanced cutaneous T cell lymphoma (CTCL) is significantly contracted despite the presence of relatively normal absolute numbers of T cells. We propose that many normal T cells were being lost in patients with CTCL, with the remaining normal T cells expanding clonally to fill the T cell compartment. T-cell receptor excision circles (TREC) form as a...
متن کاملLymphocyte toxicity and T cell receptor excision circles in workers exposed to benzene.
We have previously reported that benzene decreases peripheral white blood cell and platelet counts and specifically lowers subsets of several blood cell types, including CD4+-T cells, B cells, NK cells, and granulocytes. Diminished thymus function has been implicated as a mechanism for CD4+-T cell loss in other conditions such as AIDS by assays of T cell receptor excision circles (TRECs), a mar...
متن کاملT-cell Receptor and K-deleting Recombination Excision Circles in Newborn Screening of T- and B-cell Defects: Review of the Literature and Future Challenges
Since its introduction as a public health programme in the United States in the early 1960s, newborn blood screening (NBS) has evolved from the detection of phenylalanine levels on filter paper to the application of DNA-based technologies to identify T-cell lymphopenia in infants with severe combined immunodeficiency. This latter use of NBS has required the development of an assay for T-cell ly...
متن کاملMeasuring emigration of human thymocytes by T-cell receptor excision circles.
Recent advances in characterizing thymic function confirm the importance of thymus to T-cell diversity in the periphery of both children and adults during both health and disease. Lack of a marker to identify human recent thymic emigrants (RTEs) is the biggest hurdle to accurately characterizing and quantifying thymic output. T-cell receptor excision circles (TRECs) are used as an assay to meas...
متن کاملReevaluation of T cell receptor excision circles as a measure of human recent thymic emigrants.
The human thymus exports newly generated T cells to the periphery. As no markers have been identified for these recent thymic emigrants (RTE), it is presently impossible to measure human thymic output. T cell receptor excision circles (TREC) have been recently used to assess thymic output during both health and disease. Using a mathematical model, we quantify age-dependent changes both in the n...
