IL6 and viral infectious disease: Viral strains which induced relatively high levels of IL-6 and CCL5, (NH1125B, NH1001B and NH1161B) (Fig 6A and 6B designated as “high inducers”), had similar dynamic changes in overall gene expression whereas viral strains that induced relatively lower concentrations of IL-6 and CCL5, (NH1067B, NH1182B, TX11-56B) (designated as “low inducers; Fig 6A and 6B), displayed similar functional fingerprints and relatively little induction of genes that are typically expressed in response to viral infection.
