From: Heat-labile enterotoxin enhances F4-producing enterotoxigenic E. coli adhesion to porcine intestinal epithelial cells by upregulating bacterial adhesins and STb enterotoxin

Figure 4

Treatment with cAMP up-regulates the expression of F4 fimbriae, flagellin, and STb. AWild-type ETEC C83902 was incubated with 0, 2, 5, or 10 µM cAMP for 3 h, with mRNA expression of faeG, fliC, estA (STp), and estB (STb) was examined by qRT-PCR. The mRNA level of faeG, fliC, estA, and estB genes without cAMP treatment was considered 100%. The data are expressed as the mean ± SD of four experiments. B The protein expression of F4 fimbriae and flagellin from ETEC C83902 after treatment of with 0, 2, 5, or 10 µM cAMP.
