Trophoblast Cell Function in the Antiphospholipid Syndrome.

Area of Science:

• Obstetrics and Gynecology
• Immunology
• Reproductive Medicine

Background:

• Antiphospholipid syndrome (APS) is an autoimmune disorder linked to antiphospholipid antibodies (aPL).
• Women with APS face high risks of pregnancy loss and complications like preeclampsia and premature birth.
• Vascular thrombosis is a known complication, but direct effects of aPL on placental cells are increasingly recognized.

Purpose of the Study:

• To review the mechanisms of antiphospholipid antibody-induced trophoblast dysfunction in obstetric APS.
• To explore the direct impact of aPL on placental cell function and survival.
• To discuss the role of non-coding RNAs in obstetric APS pathogenesis.

Main Methods:

• Literature review of current findings on APS and aPL.
• Analysis of studies investigating aPL effects on trophoblast cells (survival, function, internalization).
• Examination of research on non-coding RNAs in obstetric APS.

Main Results:

• Antiphospholipid antibodies (aPL) directly impair trophoblast cell survival and function.
• aPL internalization by trophoblast cells is a key mechanism in obstetric APS.
• Non-coding RNAs are implicated in trophoblast dysfunction and obstetric APS pathogenesis.

Conclusions:

• Trophoblast dysfunction caused by aPL is a significant factor in obstetric APS, independent of thrombosis.
• Understanding aPL-induced trophoblast damage is crucial for managing APS in pregnancy.
• Non-coding RNAs represent a potential therapeutic target for obstetric APS.
