Integrin β3 mRNA is increased in cells from sputum samples of TB patients. Induced sputum samples were collected prospectively from patients with active pulmonary TB (n = 15) and control subjects (n = 11) in Cape Town. Integrin β3 mRNA accumulation was analyzed by real-time RT-PCR, and β-actin mRNA was used as the control gene. Horizontal lines represent median values. Statistical analysis was performed using a Mann–Whitney U test (*p < 0.05).
