<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, cell proliferation was assessed by [<sup>3</sup>H]-TdR incorporation. The results are presented as the means ± standard deviation of triplicate assays from six mice/group. <sup>ns</sup>p>0.05, *** p < 0.001 versus the control APS group.</p
