Plasma protein levels of TNF and TNF superfamily receptor proteins in HTLV-1 ACs, ATL patients, and patients in remission. sTNFR2 (n = 102) (A), sTNFR1 (n = 38) (B), TNFα (n = 38) (C), and sTNFRSF8 (n = 38) (D). Statistically significant P values in ACs vs ATL patients are shown. *P < .05, **P < .01, ***P < .001.
