CD3⁺ synovial T cells exhibit minimal levels of apoptosis in rheumatoid arthritis synovium both before and after intra-articular glucocorticoids. Photomicrographs illustrate fluorescent staining of CD3⁺ cells (red, rhodamin red) before (a) and after therapy (b), TUNEL⁺ cells (green, fluorescein) before (c) and after therapy (d) (b, e), and superimposed stainings before (e) and after therapy (f) (original magnification × 320). TUNEL, terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end-labeling.
