Furthermore, transcriptional profiling of hBMEC during infection with B. anthracis revealed downregulation of 270 (87%) genes, specifically key neutrophil chemoattractants IL-8, CXCL1 (Groα) and CXCL2 (Groβ), thereby strongly contrasting hBMEC responses observed with other meningeal pathogens. The gene discussed is CXCL8; the disease is infection.
