Correlation of serum IgA levels and circulating TFH cells in HCs and HSP patients. (a) and (b) Relationship of serum IgA levels and the percentage of CXCR5⁺ in CD4⁺TFH cells in HC and HSP patients, respectively. (c) and (d) Relationship of serum IgA levels and the percentage of ICOS⁺CXCR5⁺ in CD4⁺TFH cells in HCs and HSP patients, respectively. Data shown were the mean ± SD. The horizontal lines show the median.
