TLR2 gene expression was measured in both lung (left) and spleen (right) homogenates in either spontaneously breathing rabbits (SB) or animals subjected to mechanical ventilation (MV) with or without atorvastatin pre-treatment (n = 5 in each group). All values are reported as fold increases compared with SB rabbits. Results are expressed as mean±standard deviation. Kolmogorov-Smirnov test was used for all intergroup comparisons.
