CCL3 and tuberculosis: M. tuberculosis- induced CCL3 concentrations were found to be comparable between the pulmonary and extrapulmonary TB patients studied (Fig. S1B: median; PTB, 1306; L-ETB, 999 D-ETB, 1471 pg/ml, respectively), as well as between PTB patients with either minimal or moderate disease (median; min-PTB, 974; mod-PTB, 1425; p = 0.653).
