Genes preferentially expressed in human Th1 cells as measured by oligonucleotide microarrays. Genes expressed at higher level in Th1 cells (black bars) as compared to Th2 cells (white bars) at day 14 are shown. Fluorescence intensity values for (a) genes with increased expression levels of >400, and (b) genes with expression levels increased by <400. Error bars indicate variation in two hybridizations from duplicate preparations of the same sample.
