Figure 2From: Acute exposure of mice to high-dose ultrafine carbon black decreases susceptibility to pneumococcal pneumoniaCarbon loading of human alveolar macrophages (AM) from an adult exposed to biomass smoke in Malawi. AM were obtained by bronchoalveolar lavage. Image taken under oil immersion (x100). Black material represents phagocytised elemental carbon and the pattern of loading is compatible with moderate- to heavy-loading of AM in UF-CB exposed mice (Figure 1).Back to article page
