IL-17 producing T cells correlate with polysensitization but not with bronchial hyperresponsiveness in patients with allergic rhinitis.

Background: Th2-type T cell response has a considerable role in atopic diseases. The involvement of Th17 and IL-17 in atopy process provided new understanding of allergic diseases. Bronchial hyperresponsiveness is quite common in allergic rhinitis.

Flow cytometric investigation of CD40-CD40 ligand system in preeclampsia and normal pregnancy.

Our aim was to investigate the CD40-CD40 ligand system in preeclamptic women. We also studied CD62P and platelet-monocyte aggregates, which have been closely linked to the CD40-CD40L system. Platelet expression of CD40L and CD62P and expression of CD40 on monocytes and platelet-monocyte aggregates were determined by flow cytometry in whole blood from 23 preeclamptic women, 23 normotensive pregnant women, and 23 nonpregnant women.
