Measurement of T Cell Alloreactivity Using Imaging Flow Cytometry
The measurement of immunological reactivity to donor antigens in transplant recipients is likely to be crucial for the successful reduction or withdrawal of immunosuppression. The mixed leukocyte reaction (MLR), limiting dilution assays, and trans-vivo delayed-type hypersensitivity (DTH) assay have all been applied to this question, but these methods have limited predictive ability and/or signi...
متن کاملAnalysis of T Cells Using Flow Cytometry
T cells are an essential cellular component of the immune system. When T cells encounter antigen and receive co-stimulatory signals, they become activated, proliferate and produce cytokines. Flow cytometry is a valuable research tool in analyzing T cell functions including proliferation, survival and cytotoxicity as well as cytokine production and cell signaling. This article has reviewed the u...

متن کامل62 Analysis of T Cell Alloreactivity
The genetic and biochemical basis for the inclusion of T cell alloreactivity within the immunological repertoire of T helper (Tn) 1 lymphocytes remains a perplexing problem (1, 2). Recent evidence (3-9) suggests that the ability of Tn cells to bind to molecular complexes formed on antigen-presenting ceils between a nominal antigen and either self or nonself (allo) Ia molecules regulates their d...
متن کاملAbsolute bacterial cell enumeration using flow cytometry.
AIM To evaluate a flow cytometry protocol that uses reference beads for the enumeration of live and dead bacteria present in a mixture. METHODS AND RESULTS Mixtures of live and dead Escherichia coli with live:dead concentration ratios varying from 0 to 100% were prepared. These samples were stained using SYTO 9 and propidium iodide and 6-μm reference beads were added. Bacteria present in live...
