Purified CD8+ T cells were treated with and without IL-2 (500 u/ml) overnight before their co-culture with and without IFN-γ (200 u/ml) treated vector alone and IκB(S32AS36A)
transfected HEp2 cells (E:T ratio 1:1). After two weekly stimulations with freshly supplemented IL2, the supernatants were removed from the CD8+ T /HEp2 cell cocultures
at the indicated days in the table and assayed for released GM-CSF by a specific and sensitive ELISA. IFN-γ treated HEp2 cell transfectants were washed three
times before they were added to IL-2 treated CD8+ T cells. No secretion of GM-CSF from vector-alone or IκB(S32AS36A) transfected HEp2 cells in the absence of CD8+ T cells
could be observed (data not shown). The p value for the difference between secretion of GM-CSF in the co-cultures of CD8+ T cells with control HEp2-vec and IκB(S32AS36A)
transfected HEp2 cells are less than 0.05. 1 of 3 representative experiments is shown in this table. |
