Increased Serum Interleukin-2 Levels Are Associated with Abnormal Peripheral Blood Natural Killer Cell Levels in Patients with Active Rheumatoid Arthritis

<div>Phenotypic characterization of lymphocyte subpopulations by flow cytometry. (a) Representative flow cytometry analysis of peripheral lymphocytes. T: CD45+ CD3+; B: CD45+ CD3- CD19+; NK: CD45+ CD3- CD16+ CD56+; CD4+ T: CD45+ CD3+ CD4+; CD8+ T: CD45+ CD3+ CD8+. (b) Representative flow cytometry analysis of CD4+ T cell subsets. All dot plot analysis is of CD4+ gated lymphocyte. Th1:CD4+ INF-<i>γ</i>+; Th2: CD4+ IL-4+; Th17: CD4+ IL-17+; Treg: CD4+ CD25+ Foxp3+.</div>
