Expression of miR-451, miR-668, miR-1902, and miR-1904 of serum and WBCs from C57BL/6 and Tlr2^−/−mice from real-time RT-PCR experiments 6 h after exposure to 100 μg of LTA or phosphate-buffered saline (PBS); **, P < 0.01 vs. control of C57BL/6 or Tlr2^−/−. (A) C57BL/6 mice receiving injection of PBS or LTA; (B) Tlr2^−/− mice receiving injection of PBS or LTA; (C) C57BL/6 or Tlr2^−/− mice upon injection of LTA.
