Targeting local vascular and systemic consequences of inflammation on vascular and cardiac valve calcification

Area of Science:

• Cardiovascular Research
• Nephrology
• Inflammation Biology

Background:

• Vascular calcification (VC) is linked to cardiovascular mortality in the general population and chronic kidney disease (CKD) patients.
• Systemic inflammation, driven by conditions like CKD and diabetes, is associated with VC.

Purpose of the Study:

• To review evidence linking inflammation to the progression of vascular calcification.
• To explore the molecular mechanisms by which inflammation affects VC.

Main Methods:

• Collated clinical and experimental evidence on inflammation's role in VC.
• Reviewed the impact of pro-inflammatory cytokines (e.g., TNF, IL-6) and transcription factors (e.g., NF-κB) on VC.
• Examined the influence of senescence and circulating factors (Fetuin A, Klotho) in inflammation-driven VC.

Main Results:

• Inflammatory cytokines and NF-κB directly promote calcification in cellular and animal models.
• Inflammation can indirectly accelerate VC by reducing protective factors like Fetuin A and Klotho.
• Experimental data suggests a causal relationship between inflammation and VC progression.

Conclusions:

• A causal link between inflammation and VC suggests potential shifts in clinical prevention and treatment strategies.
• The precise molecular mechanisms underlying inflammation-induced VC require further elucidation.
• Further research is needed on the effects of anti-inflammatory biologics and dietary phosphate on VC in specific patient populations.
