CD25 molecule - Opis:
- WC1+ cells in cattle exhibit both regulatory and effector activities. However, it has not been elucidated whether they are so plastic that both activities co-exist in one cell or there are separate subpopulations of effector and regulatory cells. Since the production of IFN-γ and IL-10 seems to be related to WC1+ cells’ effector and regulatory function, respectively, the main aim of this study was to determine whether those cytokines are produced by separate subpopulations of WC1+, or are co-produced by the same cells. Due to increasingly frequent emphasised role of consumption of IL-2 in the mechanism of suppressor action of mouse CD25+CD4+ T regulatory cells, expression of the receptor’s α chain for interleukin 2 (CD25) on WC1+ lymphocytes has been evaluated. An average of 5.21% of WC1+ cells obtained from PBMCs of 12-month-old heifers show constitutive expression of the CD25 molecule, with CD25highWC1+ and CD25lowWC1+ cells accounting for 1.05% and 4.10% of WC1+ lymphocytes, respectively. For detection of intracellular cytokine production, PBMCs were stimulated with concanavalin A. Both IFN-γ- and IL-10-producing cells within the CD25-WC1+ and CD25+WC1+ subpopulations were mainly separate subpopulations. The average percentage of IFN-γ+IL-10-, IFN-γ-IL-10+ and IFN-γ+IL-10+ cells among CD25-WC1+ lymphocytes was 4.03%, 2.67% and 0.51%, respectively. A positive correlation was observed between the presence of the CD25 molecule on WC1+ lymphocytes and production of IL-10 and TGF-β, because the average percentage of IFN-γ-IL-10+ and IFN-γ+IL-10+ among CD25+WC1+ lymphocytes was 3 and 4.5 times higher as compared to the corresponding cells in the CD25-WC1+ subpopulation, whereas the percentage of IFN-γ+IL-10- cells in both the subpopulations was not significantly different. The percentage of TGF-β+ cells within the CD25+WC1+ subpopulation was 2.72 times as high as that of CD25-WC1+ lymphocytes. Therefore, with respect to the production of IFN-γ, IL-10 and TGF-β, CD25+WC1+ lymphocytes turn out to have a more suppressor profile than CD25-WC1+.
