Summary
Placenta-derived extracellular vesicles (pcEV) can cause preeclampsia by damaging blood vessels. Enhancing the removal of these vesicles may offer a new treatment for this pregnancy complication.
Area of Science:
- Obstetrics and Gynecology
- Vascular Biology
- Perinatal Medicine
Background:
- Preeclampsia is a serious pregnancy complication linked to elevated placenta-derived extracellular vesicles (pcEV).
- The causal role of pcEV in preeclampsia pathogenesis remains unclear.
Purpose of the Study:
- To investigate the impact of pcEV on preeclampsia development using mouse models.
- To explore pcEV as a potential therapeutic target for preeclampsia.
Main Methods:
- Detection of pcEV in pregnant mice.
- Infusion of purified vesicles from injured placenta into pregnant mice.
- Assessment of hypertension and proteinuria development.
- Evaluation of extracellular vesicle clearance enhancement.
Main Results:
- Pregnant mice infused with vesicles from injured placenta developed hypertension and proteinuria.
- These pcEV disrupted endothelial integrity and induced vasoconstriction.
- Enhancing extracellular vesicle clearance prevented preeclampsia development in mice.
Conclusions:
- Placenta-derived extracellular vesicles play a causal role in preeclampsia.
- Microvesicle clearance represents a novel therapeutic strategy for preeclampsia.

Most chemical reactions in cells require enzymes—biological catalysts that speed up the reaction without being consumed or permanently changed. They reduce the activation energy needed to convert the reactants into products. Enzymes are proteins, that usually work by binding to a substrate—a reactant molecule that they act upon.
Enzymes exhibit substrate specificity, meaning that they can only bind to certain substrates. This is mainly determined by the shape and chemical...

Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...

In eukaryotic cells, cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...

Vesicle budding is orchestrated by distinct cytosolic proteins such as adaptor proteins, coat proteins, and GTPases. To initiate vesicle budding, membrane-bending proteins containing crescent-shaped BAR domains bind to the lipid heads in the bilayer and distort the membrane to form a protein-coated vesicle bud. Adaptors proteins such as AP2 for clathrin-coated vesicles can nucleate on the deformed membrane. Finally, coat proteins such as clathrin or COPI and COPII assemble into a coat forming...
