Fig. 2: Expressions of CD39, CD73, and CD26 on various types of ATLL cells, and the correlation of CD39 expression with prognosis.

a–c Plot of the mean fluorescence intensities (MFIs) of CD39, CD73, and CD26 on the cells in fraction P (CADM1−CD7+) and fraction N (CADM1+CD7−). Horizontal bars indicate median values. CD39 and CD26: P < 0.001, and CD73: P < 0.01. d, e Frequencies of CD39+ and CD73+ cells among CD4+ T cells within fraction N (CADM1+CD7−) from patients with acute/lymphoma, chronic/smordering subtypes of ATLL or HTLV-1 carrier. f Transformation-free survival of chronic/smoldering patients stratified by CD39 expression leukemic cells. Patients with chronic (n = 12) and smoldering (n = 2) ATLL were followed after blood collection up to a maximum of 2 years. Solid line indicates CD39+ patients, and dotted line indicates CD39−.
