IRIS è il sistema di gestione integrata dei dati della ricerca (persone, pubblicazioni, progetti, attività) adottato dall’Università di Palermo, e ha lo scopo di raccogliere, conservare, documentare, e diffondere ad accesso aperto le informazioni relative alla produzione scientifica degli autori afferenti all’Ateneo.
EnglishThe aim of this study was to investigate the influence of 50 Hz magnetic or static magnetic fields of 0.5 mT on subsets of human CD4+ T cells in terms of cytokine release/content, cell proliferation and intracellular free calcium concentration. CD4+ T cells can be divided into different subsets on the basis of surface marker expression, such as CD45, and T cells can be divided into naive (CD45RA+) and memory (CD45RA2) cells. In this study, the effects of magnetic fields after 24 and 48 h of cell culture were analyzed. We found that the CD4+CD45RA2 T subset were more sensitive after 2 h of exposure. Decreases in the release/content of IFN-c, in cell proliferation and in intracellular free calcium concentrations were observed in exposed CD4+CD45RA2 T cells compared to CD4+CD45RA+ T cells. The results suggest that exposure to the magnetic fields induces a delay in the response to stimulants and that modifications are rapidly reversible, at least after a short exposure.
