Genes differentially expressed in healthy donor PBMCs after rV-B7.1 infection. Healthy donor (n = 6) PBMCs were treated with rV-B7.1 vaccine for 12 hours and gene expression profiles were analyzed using a customized 32x24x23 (~17,000 spot) human cDNA microarray. Ten immune-related genes of interest showing high degrees of up-regulation and ten immune-related genes showing high degrees of down-regulation are listed along with their intensity ratios. All genes tested are listed in Additional files1 and2. *P < 0.05.
