Progress in impact of interaction between Treponema pallidum and ma-ternal-fetal interface cells on pregnancy outcomes / 中国病理生理杂志

ABSTRACT

Treponema pallidum(Tp),a common sexually transmitted pathogen,can infect the fetus via pla-cental vertical transmission,leading to congenital syphilis(CS).This infection results in adverse pregnancy outcomes,such as stillbirth,miscarriage,preterm birth,and fetal growth restriction.However,the exact pathogenesis remains un-clear.Studies indicate that patients with early syphilis primarily exhibit pro-inflammatory immune responses.The Tp has been proven to induce dysfunction in various immune cells and abnormal expression of cytokines,potentially disrupting im-mune tolerance homeostasis and leading to adverse pregnancy outcomes.Grounded in the current understanding of CS and maternal-fetal immunology by scholars both domestically and internationally,this paper provides a comprehensive review of the potential mechanisms of Tp interacting with the cells of the maternal-fetal interface,ultimately leading to adverse pregnancy outcomes.It summarizes the pathogenesis characteristics,clinical manifestations,and maternal-fetal immune responses of CS.
