TCR+αβ T cells* (%)	CD19+ B cells* (%)	CD3– CD56+ NK cells* (%)	CD4/8* ratio	CD57+ T cells† (%)	CD57– T cells† (%)
92·52 ± 0·51	1·54 ± 0·26	1·89 ± 0·17	5·30 ± 0·78	16·15 ± 0·89	83·85 ± 0·89

TCR = T cell receptor; NK = natural killer. Data were obtained from 52 patients with sarcoidosis. Values are expressed as the mean ± s.e.m.
