  • The microarray includes the listed genes. Expression of each gene was confirmed by 3′RACE. 3′RACE products corresponded with the most probable GenBank matches

    The tag sequence represents the 10-bp SAGE tag. Count indicates the number of times the tag was identified. Each tag number was normalized by using SAGE software by calculating 32,000

    Fold change in expression was calculated as follows. After normalization of the number of each tag, the relative expression of each transcript was determined by dividing the number of tags observed in activated Th1, activated Th2, or resting T lymphocytes as indicated. To avoid division by zero, we used a tag value of one for any tag that was not detectable
