Figure 3 GGT-deficient H pylori mutants fail to inhibit lymphocyte proliferation. (A) Cell proliferation of stimulated peripheral blood mononuclear cells in the presence or absence of indicated H pylori supernatants was determined by 3H-thymidine incorporation assay. (B) GGT phenotype of constructed knock-out strains was confirmed by enzyme activity assay and immunoblotting using a polyclonal antibody raised against the large GGT subunit. For immunoblotting, 30 μg protein of H pylori supernatants were used. Immunoblotting with anti-VacA antibody served as a loading control. Data represent mean ± SD of 3 independent experiments. *P < .001 as determined by Student t test were considered significant. WT, wild type.

Figure 4 Oderants stimulate serotonin release by enterochromaffin BON cells. BON cells were incubated for 15 minutes in serum-free medium with oderant. Serotonin release was measured in the culture supernatant by a serotonin enzyme immunoassay kit (ELISA). Concentration-dependent serotonin release by BON cells was triggered by thymol, but not phenol. P values correspond to Student–Newman–Keuls test.
