Popis: Summary Background Asthma is a chronic inflammatory disorder in which Th2, Th1 and suppressive T cells (Tregs) play a role. The transcription factor FoxP3 plays a role in Treg differentiation while T-bet is important for Th1 and GATA-3 for Th2 differentiation from naive Tcells. Recent data show that age-related deregulation of Treg cells is a mechanism of senescence affecting several chronic diseases. It is crucial to understand the behaviour of these cell populations in asthma for elderly patients. Objective To evaluate FoxP3, GATA-3 and T-bet gene expression under basal conditions and after in vitro activation in a group of elderly asthmatic compared with age-matched healthy individuals. Methods Thirty-two elderly asthmatics and 17 healthy elderly individuals were selected. Serum total IgE was measured, and peripheral blood mononuclear cells (PBMCs) were isolated and stimulated in vitro with anti-CD3/anti-CD28, followed by mRNA isolation. After reverse transcription, real-time quantitative PCR was performed and relative quantification was determined 2 DDCt(2 DDCt method). Results The mean values and standard deviation of FoxP3, GATA-3 and T-bet relative
