TNF-α expression after 8-h exposure to four sizes of Crystalline Silica, showing that for an 8-h exposure period, each particle size created a significant increase (p-value < = 0.005) in the expression of TNF-α when compared to the negative control samples. In addition, the UF particles were found to significantly enhance the expression of TNF-α when compared to the other three particle sizes (p-value = 0.0001). ** Significant difference from C exposure at p-value = 0.0001
