Correlations between the frequencies of FDCs and immune cell subsets in chronic HBV-infected patients. a Correlations between the frequencies of FDCs and plasmablast (CD19⁺CD38⁺CD27⁺), memory B cells (CD19⁺CD27⁺CD38⁻), naïve B cells (CD19⁺CD10⁻CD27⁻), and immature B cells (CD19⁺CD10⁺CD27⁻) in peripheral blood in chronic HBV patients (n = 16). b Correlations between the frequencies of FDCs and CXCR5⁺CD4⁺ T cell and CXCR5⁺CD8⁺ T cell subsets in peripheral blood in chronic HBV patients (n = 5). c Correlations between the frequency of circulating FDCs and plasma levels of IL-6, IL-7, IL-15, BAFF, and CXCL13 in chronic HBV patients (n = 31)
