Fig. 5From: Complex regulation of neutrophil-derived MMP-9 secretion in central nervous system tuberculosisNeutrophil MMP-9 secretion is regulated by NF-kB. a Pre-incubation with helenalin inhibits MMP-9 secretion after CoMTB stimulation. b Pre-incubation with IKK2 inhibitor SC-514 inhibits MMP-9 secretion with CoMTB stimulation. c Pre-incubation with NF-kB inhibitor helenalin inhibits MMP-9 secretion after M.tb infection. Bars represent mean ± s.d and are representative of at least two independent experiments performed in triplicate. **P < 0.01; ***P < 0.001Back to article page
