Delayed human neutrophil apoptosis by Trichomonas vaginalis lysate.
Neutrophils play an important role in the human immune system for protection against such microorganisms as a protozoan parasite, Trichomonas vaginalis; however, the precise role of neutrophils in the pathogenesis of trichomoniasis is still unknown. Moreover, it is thought that trichomonal lysates and excretory-secretory products (ESP), as well as live T. vaginalis, could possibly interact with...
متن کاملA novel neutrophil-activating factor released by Trichomonas vaginalis.
We have investigated the effects of a novel neutrophil-activating factor released by Trichomonas vaginalis (TV-NAF) on neutrophil chemotaxis. TV-NAF was present in the supernatant from 10(7) T. vaginalis (STV) cultured in 1 ml of serum-free Hanks' balanced salt solution (HBSS) at 37 degrees C for 30 min. With a multichamber chemotactic assay, we found that there were 112 +/- 15 migrated neutrop...
متن کاملSuperoxide Anion Production by Human Neutrophils Activated by Trichomonas vaginalis
Neutrophils are the predominant inflammatory cells found in vaginal discharges of patients infected with Trichomonas vaginalis. In this study, we examined superoxide anion (O2 (.-)) production by neutrophils activated by T. vaginalis. Human neutrophils produced superoxide anions when stimulated with either a lysate of T. vaginalis, its membrane component (MC), or excretory-secretory product (ES...
متن کاملTrichomonas vaginalis
We have investigated the effects of a novel neutrophil-activating factor released by Trichomonas vaginalis (TV-NAF) on neutrophil chemotaxis. TV-NAF was present in the supernatant from 107 T. vaginalis (STV) cultured in 1 ml of serum-free Hanks' balanced salt solution (HBSS) at 37°C for 30 min. With a multichamber chemotactic assay, we found that there were 112 + 15 migrated neutrophils (mean ±...
متن کاملSurvival of Trichomonas vaginalis in human semen.
Although exposure of Trichomonas vaginalis to human semen is of short duration, any effect that this fluid may have on the urogenital protozoon could affect its transmission, especially if only few trichomonads are present. Small numbers of parasites (about 2500/ml semen) incubated in semen from different donors at 37 degrees C, were found to survive or grow for up to 12 hours in all samples an...
