Fig. 2. CCR4 regulates the magnitude of the lung inflammation at the chronic phase of M. tuberculosis infection.

Representative analysis of lung inflammation a and inflammation score b of WT and CCR4^−/− mice were obtained from lung sections stained with hematoxylin and eosin at 15, 30 and 70 days of infection (dpi). Magnification ×200. Data are representative of three independent experiments (n = 6–10). Bars show the difference (P < 0.05) between the groups. Arrows indicate foamy macrophage clusters
