Fig. 2From: Complex regulation of neutrophil-derived MMP-9 secretion in central nervous system tuberculosisCollagen is degraded by neutrophils stimulated with M.tb in an MMP-9 dependent manner. a Confocal microscopy of Type IV DQ collagen coated slides demonstrating collagen degradation in the presence of M.tb stimulation. DQ collagen fluorescence increases after degradation. b Type IV collagenase activity is inhibited by MMP-9 neutralizing antibody. Bars represent mean ± s.d and represent two independent experiment performed in triplicate. **P < 0.01Back to article page
