The expression of TLR4 protein in lung tissues of different groups. a The levels of TLR4 protein were determined by Western blotting analysis. b Quantification of the Western blotting data and correction by reference to the value of GAPDH expression. The data are expressed as mean ± SD (n = 8). ^▲ P < 0.01; ^△ P < 0.05 vs. group S; ^□ P < 0.05 vs. group M; ^◇ P < 0.05 vs. group D2.
