Figure Lengend Snippet: FIGURE 4 | Herpesviruses-encoded dUTPases signal through TLR2/TLR1 and MyD88. TLR2- HEK293 cells were transiently transfected with NF-κB luciferase and pRL-TK reporter plasmids and co-transfected with pCMV-TLR1 and either TLR2DN, a vector that expresses a dominant-negative form of TLR2, or empty vector (0.3 μg) (A). After 24–36 h, cells were treated with the dUTPases (10 μg/ml) encoded by HHV-6A, HHV-8 and VZV or left untreated for 8 h, and luciferase reporter gene activity was measured. Pam3Csk4 (0.1 μg/ml) was used as a positive control for TLR2/TLR1 activation and nuclear human dUTPase was used as a control protein. (B) Anti-TLR2 blocking Ab inhibits NF-κB activation by the herpesviruses-encoded dUTPases. TLR2-HEK293 cells were transiently (Continued)
