Response to TLR2-specific agonists of TLR2^−/−EFs transfected with hTLR2. Responses were compared for TLR2^−/−EFs or TLR2^−/−EFs transfected with hTLR2 (TLR2^−/−EF + hTLR2) or with the empty vector (TLR2^−/−EF + vector). The cells were stimulated for 4 hours with 100 ng/mL Pam₃CSK₄ or 100 ng/mL MALP-2. The results show mRNA levels of MCP-1, ICAM-1, and IL-6 quantified by qRT-PCR. Data are mean value ± SE of 3 independent experiments.
