Fig. 2 HTLV-1 proviral load and lymphoproliferation among HCV co-infected asymptomatic subjects and HAM/TSP patients. This figure depicts the subjects when stratified based on their clinical co-infection status. A**** shows an association on PVL among asymptomatic vs HAM/TSP. We observed a significant increase in HTLV-1 PVL in HTLV-1 monoinfected HAM/TSP subjects compared to HTLV-1 monoinfected asymptomatic subjects. The higher spontaneous LPA for HTLV-1. B* LPA was associated among asymptomatic vs HAM/TSP, and we can observed in B** that LPA was associated when compared asymptomatic HTLV-1 vs HCV with HAM/TSP subjects. (A) PVL, HTLV-1 proviral load; B, basal T-cell proliferation; (B) CPM, counts per minute.
