Figure Lengend Snippet: The effect of carbon black (CB), urban dust (UD), and nanoparticulate carbon black (NPCB) on cell membrane damage (( A ); lactate dehydrogenase (LDH) release), oxidative stress ( B ), DNA damage ( C ), and phagocytosis ( D ) in human monocytes (M), and monocyte-derived macrophages (MDM). The inflammatory response (TNFα; ( E )) to lipopolysaccharide (100 ng/mL for 24 h) is also included ( F ). All PMs were used at 100 µg/mL and the incubation time was 24 h. Cell transition was induced by phorbol-12-myristate 13-acetate (PMA; 100 nM) applied for 72 h. LDH was measured with CyQUANT LDH Cytotoxicity Assay kit, DNA ploidy was quantified using propidium iodide staining, intracellular oxidative stress was measured using 5-(and-6)-Carboxy-2′,7′-dichlorodihydrofluorescein diacetate (carboxy-H2DCFDA) while phagocytosis was assessed with fluorescent beads (Cayman Phagocytosis kit). Fluorescence was quantified with flow cytometry. TNFα was measured in the culture medium using a Multi-Analyte Inflammatory Cytokine ELISArray Kit (Quiagen, Wroclaw, Poland). Data are means ± SD of 6–10 assays. * p < 0.05; ** p < 0.01 for comparisons with the corresponding control cells; ^^ p < 0.01 for comparisons with corresponding naive cells; # p < 0.05 for comparisons with LPS-treated cells.
