Motor behavioral abnormalities and histopathological findings of Wistar rats inoculated with HTLV-1-infected MT2 cells. Braz J Med Biol Res 2010; 43: 657-662.

Figure 2. Significant (*P < 0.05) increase in the spontaneous behaviors scratching, biting, licking, and sniffing in 23 Wistar rats inoculated with HTLV-1-infected MT2 cells along 20 months of observation. Data are reported as mean delta behavior values (experimental time post-inoculation minus baseline behavior before inoculation) ± SEM (unpaired Student t-test). HTLV-1 = human T-cell lymphotropic virus type 1. Number of rats varied along the study, as follows (control/experimental): 5th month = 12/23 rats; 10th month = 11/23 rats; 15th month = 6/12 rats, and 20th month = 6/6 rats).
