Fig. 4From: Modulation of protease-activated receptor expression by Porphyromonas gingivalis in human gingival epithelial cellsProtein level of PARs in GECs by flow cytometry. a, b, c and d show representative results from the flow cytometric analyses of PAR-1, PAR-2, PAR-3 and PAR-4, respectively. The result showed GECs expressed PAR-1, PAR-2 and PAR-3, but not PAR-4. Black line: isotype control. Green line: anti-PARsBack to article page
