The biological function of ELABELA and APJ signaling in the cardiovascular system and pre-eclampsia

Area of Science:

• Cardiovascular Physiology
• Reproductive Medicine
• Endocrinology

Background:

• Pre-eclampsia (PE) is a pregnancy syndrome marked by hypertension and proteinuria, with unknown causes but linked to placental issues and vascular damage.
• The apelin receptor (APJ) system, including ligands APELIN and ELABELA, is crucial for cardiovascular regulation.
• Recent research suggests a connection between reduced ELABELA signaling and PE development, but the mechanisms are unclear.

Purpose of the Study:

• To review the role of the ELABELA-APJ system in cardiovascular homeostasis.
• To discuss how ELABELA and APJ influence placental trophoblast invasion and vascular functions.
• To explore the potential involvement of the ELABELA-APJ system in the pathogenesis of PE.

Main Methods:

• Literature review of studies on ELABELA, APJ, and pre-eclampsia.
• Synthesis of current knowledge on cardiovascular and placental functions of the APJ system.
• Discussion of proposed molecular mechanisms linking ELABELA/APJ to PE.

Main Results:

• The ELABELA-APJ system plays a significant role in maintaining cardiovascular homeostasis.
• ELABELA and APJ signaling are implicated in regulating key placental processes, including trophoblast invasion.
• Dysregulation of this system may contribute to the vascular dysfunction observed in PE.

Conclusions:

• The ELABELA-APJ system is a potential key player in the development of pre-eclampsia.
• Further research into this system could reveal novel therapeutic targets for PE.
• Understanding the molecular mechanisms is crucial for addressing PE-related complications.
