| Popis: | Background. It is presently known that several subsets of T-regulatory (Treg) cells, both natural and inducible maintain tolerance to environmental allergens. But the relative importance of distinct phenotypically defined Treg subsets for the clinical manifestations of IgE-mediated allergy has not been elucidated yet.The aim of the study was to investigate the phenotype and number of different Treg subpopulations from patients with IgE-mediated allergy compared with healthy non-allergic individuals.Materials and methods. A group of 20 patients with clinically manifested IgE allergy and a group of 10 healthy no allergic controls were included in the study. Peripheral blood samples were taken after informed consent. Percentage and absolute count (AC) of the following regulatory subsets: naive (CD45RO-FoxP3lo), memory (RO+FoxP3+), effector (Treg eff, RO+FoxP3hi), induced (CD39+CD134+), Thl7/Treg (CD196+FoxP3+CD4Treg); Tr1 (IL-10+FoxP3-), were determined using standard 8-parameter flow cytometry (BD FACSCanto II).Results and discussion. The share and AC of FoxP3+CD4 Treg was significantly decreased in sensitized patients as compared to controls (mean 0,6% vs. 3,3%, p |
