Figure 7From: Pulmonary exposure to single-walled carbon nanotubes does not affect the early immune response against Toxoplasma gondii Impaired immune response after T. gondii exposure. Single cell suspensions from spleens from mice exposed to SWCNT and/or T. gondii in two doses (103 or 104 parasites) were cultured for 66 h with or without ConA (1 μg/ml) or T. gondii antigen (1 or 10 μg/ml). 3[H]-Thymidine was added during the last 18 h and incorporation was determined by scintillation counting. Results are expressed as mean counts per minute (cpm) from six mice/group ± SD. Level of significance *** p < 0.001 determined with two-way ANOVA, and Bonferroni’s Multiple Comparison test.Back to article page
