A Th1/Th2 cytokine imbalance with a predominance of Th1 cytokines has been suggested to be of pathogenic importance in Wegener's granulomatosis. To evaluate the role of Th1/Th2 cytokines in Wegener's granulomatosis, the subsets of Th1, Th2, Tc1 and Tc2 cells from patients with active Wegener's granulomatosis were examined by intracellular cytokine flow cytometry. The population of Tc1 cells (72.0 +/- 14.4 per cent) in Wegener's granulomatosis was significantly increased compared with Tc1 cells (37.3 +/- 14.6 per cent) in control (p<0.05). Th1, Th2 and Tc2 cells in Wegener's granulomatosis were not significantly increased compared with the control cells. These results indicate that the predominance of Tc1 cells might contribute to the mechanism of the pathogenesis of Wegener's granulomatosis.

D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

D013601 T-Lymphocytes Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.

D014890 Granulomatosis with Polyangiitis A multisystemic disease of a complex genetic background. It is characterized by inflammation of the blood vessels (VASCULITIS) leading to damage in any number of organs. The common features include granulomatous inflammation of the RESPIRATORY TRACT and KIDNEYS. Most patients have measurable autoantibodies (ANTINEUTROPHIL CYTOPLASMIC ANTIBODIES) against MYELOBLASTIN.
