Fig. 6From: PCV cap proteins fused with calreticulin expressed into polymers in Escherichia coli with high immunogenicity in miceAnalysis of cytokines secreted by lymphocyte of mice. Lymphocytes isolated from the spleen of mice at 56 dpi were stimulated with PCV2 strain DF-1 for 72 h, the supernatants were collected to detect the concentrations of cytokine of IFN-γ (a), IL-10 (b), IL-18 (c), TNF-ɑ (d), GM-CSF (e) by ELISA method and the T-lymphocyte proliferation (f) . Date are shown as mean ± SEM, statistical differences between each group was measured by one-way ANOVA, *P < 0.05, **P < 0.01, ***P < 0.001, ns represented not significantBack to article page
