In the present study, we investigated whether cellular damage, as demonstrated by lactate dehydrogenase (LDH) release in the human fallopian tube (FT) infected by Neisseria gonorrhoeae (Ngo), correlated with high levels of nitric oxide synthase (NOS) mRNA and enzyme activity. Infection with Ngo induced a significant increase (~35-fold) in mRNA transcripts of the inducible isoform of NOS. Paradoxically, a reduction in NOS enzyme activity was observed in infected cultures, suggesting that gonococcal infection possibly influences translation of iNOS mRNA to the enzyme. In addition, treatment with the NOS inhibitor TRIM did not prevent gonococcal-induced cellular damage. In contrast, the addition of the inhibitor L-NAME induced a 40% reduction in LDH release,... |
