Ferroptosis of smooth muscle cells in vascular diseases: from basic principles to clinical translation
Summary
Scientists have discovered that smooth muscle cells in blood vessels can die through a process called "ferroptosis" - a type of cell death caused by iron buildup and toxic fats. This review of existing research shows that this cell death process contributes to many serious heart and blood vessel diseases, including atherosclerosis, high blood pressure, and aneurysms. Understanding how this happens could lead to new treatments that protect blood vessels and reduce the risk of heart attacks and strokes.
Vascular smooth muscle cells (VSMCs), which form the media layer of blood vessels, play a vital role in vascular homeostasis and remodeling. Dysfunction of VSMCs represents a key pathological basis and an important contributor to vascular diseases. Ferroptosis, an iron-dependent accumulation of lipid hydroperoxides, is a novel form of regulated cell death. VSMC ferroptosis is involved in a range of vascular diseases, such as atherosclerosis, vascular calcification, hypertension, aortic aneurysm, aortic dissection, neointimal hyperplasia, intracranial aneurysm, and pulmonary arterial hypertension. This review summarizes the current evidence, underlying potential mechanisms, and therapeutic targets of VSMC ferroptosis in vascular diseases. A deeper understanding of this process may provide therapeutic insights and help in mitigating cardiovascular risk in affected patients.

The interplay of ferroptosis and oxidative stress in pulmonary fibrosis: from mechanisms to treatment
This research review summarizes how a specific type of cell death called ferroptosis may contribute to pulmonary fibrosis, a serious lung disease where scar tissue builds up and makes breathing difficult. Scientists have found that when cells die from iron buildup and damage from harmful molecules, it can worsen lung scarring, but drugs that block this process show promise in animal studies. Understanding this connection could lead to new treatments for people with pulmonary fibrosis, though more research is needed to make sure these potential medicines are safe and effective in humans.
Ferroptosis induced by environmental pollutants and its health implications
Researchers reviewed how environmental pollutants — including microplastics, PM2.5, and heavy metals — trigger ferroptosis, a form of programmed cell death driven by iron and fat oxidation, finding that targeting this cell death pathway could be a strategy to reduce organ damage caused by pollution exposure.
Understanding the mechanistic roles of microplastics combined with heavy metals in regulating ferroptosis: Adding new paradigms regarding the links with diseases
This review explores the emerging connection between microplastics combined with heavy metals and a type of cell death called ferroptosis, which involves iron-dependent damage to cell membranes. Researchers found that both microplastics and heavy metals can independently trigger ferroptosis, and their combined presence may amplify this effect in organs like the liver, kidneys, and brain. The study suggests that understanding this cell death pathway could provide new insights into how environmental pollutant mixtures contribute to disease.
Exposure of polystyrene nanoplastics led to ferroptosis on cardiomyocytes
Researchers exposed rat heart cells to 100-nanometer polystyrene nanoparticles and found that the particles were taken up by the cells and triggered a form of iron-dependent cell death called ferroptosis. The nanoparticles caused a buildup of reactive oxygen species in mitochondria, iron accumulation, and damage to cell membranes. The study suggests that nanoplastic exposure may pose risks to heart health through this specific cell death pathway.
International consensus guidelines for the definition, detection, and interpretation of autophagy-dependent ferroptosis
This scientific review provides guidelines for understanding a specific type of cell death called autophagy-dependent ferroptosis, where cells essentially digest their own protective components and then die from iron-driven damage. While not directly about microplastics, this process is relevant because microplastics and nanoplastics have been shown to trigger oxidative stress and iron-related cell damage in tissues. Understanding these cell death pathways helps researchers assess how plastic particle exposure could harm organs like the liver, brain, and lungs.
