Results of the correlation between CD28 and B7-2 in spleen of immunosuppressed rats (n = 3 per each group). A immunofluorescence results, a–f Pearson correlation scatterplot; B CD28 and B7-2 colocalization results. Data are expressed as Pearson correlation coefficient, Kruskal–Wallis one-way ANOVA test. ^**p < 0.01 vs NG; ^##p < 0.01 vs CTX. NG: normal group; CTX: cyclophosphamide; HPM: Herb-partitioned moxibustion; aCD28: anti-CD28; aCTLA-4: anti-CTLA-4; LEV: Levamisole
