title: Anti-inflammatory non-steroidal drug able to modulate IL-10 in allergic asthma.
abstract: Our studies target alternative/adjuvant therapies in allergic diseases, able to qualitatively/quantitatively modify cytokine profiles produced by both CD4+ T-cell subsets (mainly Th1 and Th2) and B-cells, macrophages, etc. Current investigations aim to identify compounds capable to down-regulate IL-10 as an exponent of Th2 cell function and, consequently, to up-regulate Th1 cytokine levels. Experiments on ten allergic asthmatic patients and ten healthy subjects as control were performed. Cytokine production, triggered in PBMCs culture systems by PHA, was modulated with Indomethacin, a non-steroidal anti-inflammatory drug and IL-10 was measured in 24 hours culture supernatants. According to our experimental data, IL-10 level of asthmatic patients' PBMCs in the resting state is not significantly different from control. PHA-activated PBMCs from asthmatic patients do not display significantly higher IL-10 levels than the normal subjects. The results obtained up-to-date reveal the fact that Indomethacin strongly down-regulates IL-10 levels in PBMCs cultures, in both asthmatic allergic patients and healthy subjects. It is obvious that the inhibitory effect of Indomethacin on IL-10 released by PBMCs is higher in the case of allergic asthmatic patients. The results obtained in this study demonstrate that Indomethacin is a possible therapeutic candidate in allergic asthma.
