Notably, CB1R expression strongly correlated with disease activity, while patients in remission showed expression patterns more similar to healthy individuals. Furthermore, CB2R expression in specific B-cell subsets correlated with clinical manifestations, and its distribution pattern demonstrated a significant ability to distinguish between active disease and remission in ROC analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>These
