Flow cytometry analysis of the frequency and phenotype of blood CXCR5<sup>+</sup>CD4<sup>+</sup> T cells from HBV patients with or without autoantibodies.

<p>The frequencies of total blood CXCR5<sup>+</sup>CD4<sup>+</sup>T cells and ICOS-1<sup>+</sup>/ PD-1<sup>+</sup>/ CD40L<sup>+</sup>/ IL-21R<sup>+</sup>CXCR5<sup>+</sup>CD4<sup>+</sup>T cells were compared between autoantibodies negative HBV patients (auto-Ab- HBV, n = 30), and autoantibodies positive HBV patients (auto-Ab<sup>+</sup>HBV, n = 55). Means and standard errors of cell frequency are shown. *, P < 0.05, ***, P < 0.001, NS, not significant.</p>
