CD20 expression on primary Sjögren's syndrome (pSS) circulating and glandular interleukin (IL)‐17‐producing T cell subsets. The expression of CD20 surface levels was assessed on circulating IL‐17⁺ double‐negative T and T helper type 17 (Th17) cells in the peripheral blood at baseline (T0) and after 3 (T3) and 6 (T6) months of rituximab (left). P‐values were calculated with one‐way analysis of variance for repeated‐measures and multiple‐comparison post‐hoc tests. CD20 surface level was also assessed on glandular IL‐17⁺ double‐negative and Th17 cells of treatment‐naive patients (right). P‐value was calculated with the Mann–Whitney U‐test. The plots display mean ± standard error of the mean.
