Expression of highly predicted gene clusters. A. The cross-prediction approach was taken to predict expression (green line) of the proinflammatory cytokine IL-6. The observed expression is shown as a red line. B. Behavior of RSAD2 and OASL in macaque based on the model inferred from Calu-3 expression data. This figure shows that the in vitro Calu-3 system can be highly informative about the behavior of certain genes in a whole macaque infection.
