After irradiation with 0.5, 2,4 and 8Gy ,γ, rays, CD28 and Fas (CD95)molecule expression in human T lymphocytes were measured by flow cytometry (FCM) with direct immunofluorescence technique. Before and after treatment of T cells with CD28McAb and IL—18, the T cells apoptosis was determined by JAM test and FCM technique. Results showed that with the increasing radiation dosage, the CD28 molecule expression decreased and the CD95 molecule expression increased in CD3,+,T cells, which could affect signal transduction and increase cell apoptosis. However,after using CD28 McAb and IL—18 to treat the cells irradiated, Fas expression and T cell apoptosis decreased.
