Flow cytometric analysis of lymphocyte activation, adhesion, and proliferation markers after flecainide treatment. Splenocytes from mice treated with vehicle, 2 µM, or 5 µM flecainide were stimulated with CD3/CD28 antibodies and analyzed for expression of the proliferation marker Ki-67 (A), adhesion molecules CD11a (B) and CD49d (C), and activation markers CD25 (D) and CD69 (E) within CD3⁺, CD4⁺, CD8⁺, and CD19⁺ cell populations. No significant differences were observed between treatment groups. Bars represent mean ± SD. n = 5 mice per group.
