Figure Lengend Snippet: IL-2 secretions of splenocytes restimulated with irradiated B16-MAGE-1 were measured using ELISA. C57BL/6 mice were vaccinated as described in Fig. 1. The splenocytes were pooled 2 weeks after the booster. Splenocytes (4×106) were cocultured with 5×105 irradiated B16-MAGE-1 cells for 3 days in a final volume of 2 ml, and the supernatants were obtained and the concentrations of IL-2 were determined using murine IL-2 ELISA kits. Statistical analysis by a paired Student’s t-test demonstrated that the IL-2 concentration in supernatants of splenocytes from mice vaccinated with MAGE-1-HSP70 fusion DNA was higher than that from mice with MAGE-1 DNA (p<0.05, n=6), or with a mixture of MAGE-1 DNA and HSP70 DNA (p<0.05, n=6)

Article Snippet: Cytokine detections Splenocytes (4×10 6 ) were harvested 2 weeks after the last vaccination and cocultured with 5×10 5 irradiated B16-MAGE-1 cells in a total volume of 2 ml of DMEM, supplemented with 10% (v/v) fetal bovine serum, 2 mM l -glutamine, 100 U/ml penicillin and 100 μg/ml streptomycin in 24-well tissue culture plates for 72 h. The supernatants were harvested and assayed for the presence of IL-2 using murine IL-2 ELISA kits (Diaclone, Besancone, France) according to the manufacturer’s protocol.

Figure Lengend Snippet: MAGE-1–specifc antibody titers in C57BL/6 mice vaccinated with various recombinant DNA vaccines. C57BL/6 mice were vaccinated as described in Fig. 1. Serum samples were obtained from vaccinated mice 2 weeks after the boost vaccination. The presence of MAGE-1–specific antibody was examined by ELISA. The anti-MAGE-1 sera from mice vaccinated with MAGE-1 protein were used as positive controls. The results of the 1:50 dilution are presented showing the mean absorbance (A 450nm)±SE. No anti-MAGE-1 antibodies could be detected in the sera of mice of any vaccinated group

Figure Lengend Snippet: Mice were immunized (priming) with chimeric proteins either alone (pO, pNO), or bound to T5 CLP (pO-CLP, pNO-CLP) or supplemented with CFA. Mice were subsequently boosted under the same conditions (except that CFA was replaced by incomplete Freund adjuvant, IFA). The interval between priming and boosting was of two ( a ) or six months ( b ). a , b IFNγ-producing splenocytes were quantified by ELISPOT and ( c ) IFNγ production by splenocytes was measured by ELISA after in vitro restimulation with Ova 257-264 peptide 10 days after boosting. The bars correspond to the mean of each group ( n = 5–6) and the circles to results of individual mice. Results were analyzed using one-way ANOVA followed by Tukey’s multiple comparison test with p < 0.05 considered significant (ns non-significant; ** p < 0.01; *** p < 0.001).

Article Snippet: For ELISPOT, plates were revealed with supplied reagents (murine IFNγ ELISPOT kit, Diaclone) and spots were counted with the ImmunoSpot® S6 FluoroSpot Line Plate Reader (C.T.L.).

Figure Lengend Snippet: Hippocampus of SAMP8 mice revealed an exacerbated acute inflammatory response to lipopolysaccharide (LPS) at young age and null responsiveness at old age. Sickness behavior 3 h after 3 mg/kg i.p. of LPS showed the effect of treatment and a lowering effect of age in the response of both SAMR1 and SAMP8 mice (A) . Blood serum levels of Interleukin 1β (IL1β) were increased in all groups of mice treated with LPS for 3 h regardless of strain and age (B) . Cerebral cortical levels of protein and mRNA of pro-inflammatory cytokines Interleukin 1β (IL1β/Il1b, protein/gene), Interleukin 6 (IL6/Il6, protein/gene) and Tumor necrosis factor α (TNFα/Tnf, protein/gene) were generally elevated by LPS in all mice, with lower protein levels of TNFα in all aged mice and higher mRNA levels of Il1b in SAMP8 mice; mRNA levels of all cytokines in the hippocampus showed exacerbated levels in 6-month-old SAMP8 compared to SAMR1 mice and low levels of cytokines indicative of null responsiveness to a pro-inflammatory injury in 12 month-old SAMP8 mice 3 h after LPS injection (C) . P -values for two-way ANOVA analysis are indicated at the top area of the graph: St, strain main effect; Tr, treatment main effect; Ag, age main effect; and St × Tr × Ag, interaction effect. P -values for Fisher’s LSD post hoc tests are indicated as: * p < 0.05; ** p < 0.01, *** p < 0.001 compared to the corresponding SAMR1 group, the corresponding control treatment group, or the corresponding younger mice group, as indicated. N = 3–10 mice/group.

Representative images of astrocytes stained with glial fibrillary acidic protein (GFAP) and microglia cultures stained with lectin in mixed glial cultures in control conditions or submitted to a 24-h treatment with lipopolysaccharide (LPS) 100 ng/ml + interferon γ (IFN) 0.1 ng/ml; histograms of the average cell counts of microglia per microscopic field and the percentage of microglia with reactive phenotype shown by globular morphology, as indicated (A) . Histograms of the nitric oxide generation, and the levels of pro-inflammatory cytokines Interleukin 1β (IL1β), Interleukin 6 (IL6) and Tumor necrosis factor α (TNFα) released into the culture media of mixed cultures and microglia cultures, in control conditions or treated with LPS 100 ng/ml + IFN 0.1 ng/ml, as indicated (B) . P -values for two-way ANOVA analysis are indicated at the top area of the graph: St, strain main effect; Tr, treatment main effect; and St × Tr, interaction effect. P -values for Fisher’s LSD post hoc tests between the groups indicated in the graph are as follows: ** p < 0.01, *** p < 0.001. N = 6–10 (microglia micrographs) from 3 independent cultures per group for analysis of microglia number and phenotype in mixed glial cultures, N = 18–24 (mixed glia)/15–26 (microglia) from 4 to 6 independent cultures per group for nitrite determination and N = 4–8 (mixed glia)/3–6 (microglia) independent cultures per group for cytokine analysis.
