Neutrophil Dynamics and Host Defense Mechanisms in Pregnant Women Infected with Trichomonas vaginalis

Trichomonas vaginalis, a prevalent sexually transmitted parasite, poses substantial risks to maternal health during pregnancy, eliciting a multifaceted immune response crucial for host defense. Neutrophils, as primary innate immune effectors, play a pivotal role in combatting this infection within the intricate immunological landscape of pregnancy. This comprehensive review aims to elucidate the complex interplay between Trichomonas vaginalis infection and the dynamic responses of neutrophils in pregnant women, exploring mechanisms of neutrophil recruitment, activation, effector functions, and the parasite\'s evasion strategies. Insights into neutrophil dynamics and activation mechanisms reveal their essential functions in combating T. vaginalis, encompassing chemotaxis, phagocytosis, release of reactive oxygen species, and formation of neutrophil extracellular traps. Furthermore, the review discusses how pregnancy-associated immunomodulation influences neutrophil function in response to this parasitic infection. Concurrently, the elucidation of T. vaginalis evasion tactics—surface antigen variation, adhesion strategies, and immune subversion—underscores the complexity of host-parasite interactions and the challenges faced by neutrophils in eradicating the parasite. Considering the clinical implications, particularly adverse pregnancy outcomes and maternal morbidity associated with T. vaginalis infection, the review addresses current treatment modalities, management challenges during pregnancy, and potential therapeutic strategies targeting neutrophil responses and immune modulation. In conclusion, understanding the intricate interplay between T. vaginalis infection and neutrophil dynamics within pregnancy\'s immunological context provides valuable insights into potential therapeutic targets. This review advocates for further research aiming to enhance our understanding of neutrophil-parasite interactions and develop targeted interventions to ameliorate adverse outcomes associated with T. vaginalis infection in pregnant women.
