Correlation analysis between granzyme B and interleukin-21 receptor expression and B cell subsets. Associations between granzyme B expression of CD19⁺ B cells and (a) percentages of CD19⁺CD24^intCD38^int mature B cells (R = 0.4022, p = 0.0224) as well as (b) percentages of CD19⁺CD24^highCD38⁻ primarily memory B cells (R = −0.4565, p = 0.0086). Correlations between interleukin-21 receptor expression of CD19⁺ B cells and (c) percentages of CD19⁺CD24^intCD38^int mature B cells (R = 0.4935, p = 0.0041) as well as (d) percentages of CD19⁺CD24^highCD38⁻ primarily memory B cells (R = −0.4696, p = 0.0067).
