Effect of premorbid TS exposure and TBI on vascular inflammatory responses. a Expression level of the inflammatory adhesion molecules PECAM-1 and b VCAM-1 and the pro-inflammatory regulator NF-kB c which were upregulated by TS-exposure and synergistically potentiated by TBI. n = 6 biological replicates for each experimental group. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001 vs. control. #p < 0.05, ##p < 0.01, ###p < 0.001 vs. smoke. @p < 0.05, @@p < 0.01 vs. TBI. WB analyses report protein/β-actin ratios
