with use of a battery of il-2 promoter constructs , we could not identify subregions within il-2 5'-flanking sequences which are crucial for cyclosporin a inhibition of the il-2 gene or deletion of which resulted in loss of t cell-specific expression , suggesting that such functions may be mediated at pre-transcriptional levels .
