Consistent with a Salmonella infection of host cells, we observed rapid upregulation of mRNAs encoding CXCL1 (GROα), CXCL2 (macrophage inflammatory protein 2-alpha) and CXCL8 (IL-8) for both LSMMG-infected and control-infected host cells by 30 minutes post-infection (mpi) relative to the uninfected cells (Supplementary Dataset 2). The gene discussed is CXCL1; the disease is infection.
