Gene expression of SIV-infected monkeys given the ML29 Lassa vaccine. Column one has the Genbank gene name. Column two has the fold difference in gene expression between ML29-vaccinated and uninfected (no SIV) monkeys, week 1. Column three has the fold difference in gene expression between ML29-vaccinated and SIV-infected, week 1. Column four has week one gene expression data from our previous profiling of monkeys inoculated with virulent and non-virulent strains of LCMV . The blue star indicates indicates potential virulence markers in primate and guinea pig infections with virulent/mild virus pairs.
