Effects of the β2-GPI DNA vaccine and FK506 treatment on cytokine production.

Abstract

<p>Spleen cells were purified from the different mouse groups on day 56 and stimulated with recombinant β2-GPI protein (10 μg/mL). After 96 h, (A) the culture supernatants were collected, and interferon (IFN)- γ, interleukin (IL)-4 and IL-17A production was analyzed in triplicate by ELISA. The data are presented as the means ± standard deviation (SD) of triplicate assays from six mice/group. (B) The percentages of IFN-γ-expressing CD4+ T cells, IL-4-expressing CD4+ T cells and IL-17A-expressing CD4+ T cells were determined by flow cytometry. The dot plot shows data from one representative mouse from each group. The bar graph represents the mean ± SD of six mice from three independent experiments. ^nsp>0.05, *p < 0.05, **p < 0.01 versus the control APS group.</p
