C Quantification of GFAP + -SLC31A1 + and GFAP + -FDX1 + astrocytes expressed as number per field. Data were derived from > 20 fields per tissue slice, with six mice per group and three independent experimental replicates. Values represent mean ± standard deviation. Statistical significance: ** P < 0.01 and * P < 0.05 versus Pb A-infected control mice (group d); && P < 0.01 versus naive mice (group a); NS (not significant, P > 0.05) indicates no difference compared with naive mice

Effects of DSF-CuCl 2 or TTM-CuCl 2 coculture on mRNA expression in iRBCs-stimulated astrocytes in vitro. Total RNA was isolated from astrocytes after coculture under the following conditions: a PBS-treated control (24 h or 48 h); b nonparasitized red blood cells (RBCs)-treated astrocytes (24 h or 48 h); c iRBCs-stimulated astrocytes (24 h or 48 h); d iRBCs-stimulated astrocytes cocultured with DSF-CuCl 2 (24 h or 48 h); e iRBCs-stimulated astrocytes cocultured with TTM-CuCl 2 (24 h or 48 h). mRNA levels of GFAP, Serping1, CXCL10, TNF-α, IL-1β, IL-6, SLC31A1, ATP7A, FDX1, DLAT, and DLST were quantified by qPCR using the 2 −ΔΔCT method. Data were derived from three independent experiments and expressed as mean ± standard deviation. Statistical significance: & P < 0.05 and && P < 0.01, or § P < 0.05 and §§ P < 0.01 versus PBS-treated astrocytes at 24 or 48 h, respectively; * P < 0.05 and ** P < 0.01, or # P < 0.05 and ## P < 0.01 versus iRBCs-stimulated astrocytes at 24 or 48 h, respectively; NS (not significant, P > 0.05) or ns (not significant, P > 0.05) indicates no difference compared with PBS-stimulated astrocytes at 24 or 48 h, respectively
