For example, pattern "Yers-Salm" at 48 hours includes 1,582 genes whose expression levels changed strongly after infection with Y. pseudotuberculosis or S. typhimurium (e.g. HLA-DPB1, IL10RB, CD248), but only 263 of these genes are also in the corresponding pattern when we considered the data from the 18 hour timepoint. The gene discussed is CD248; the disease is infection.
