Targeting vascular inflammation through emerging methods and drug carriers

Area of Science:

• Vascular biology and nanomedicine
• Inflammation and immunology
• Drug delivery systems

Background:

• Acute inflammation is a critical factor in numerous diseases, including sepsis, ARDS, and trauma, significantly impacting morbidity and mortality.
• Vascular and blood changes are central to the progression of inflammatory pathologies, affecting local tissues, remote organs, and systemic functions.
• Endothelial cells, lining blood vessels, play crucial regulatory roles that differ between normal and pathological states.

Purpose of the Study:

• To explore the potential of pharmacological interventions targeting endothelial cells for managing acute inflammation.
• To review current limitations of drug delivery systems (DDS) in achieving precise vascular delivery during acute inflammation.
• To provide an overview of DDS designed for targeted delivery to endothelial surface determinants for therapeutic intervention.

Main Methods:

• Overview of endothelial determinants and their role in inflammation.
• Discussion on the design principles of DDS targeted to specific endothelial molecules.
• Analysis of DDS performance in experimental models, with a focus on animal studies.

Main Results:

• DDS targeted to endothelial determinants offer specificity for tissues, organs, and cells.
• Experimental models demonstrate the potential of these targeted DDS in managing inflammatory conditions.
• Emerging nanomedicine approaches show promise for advanced therapeutic strategies.

Conclusions:

• Targeted DDS represent a promising strategy for precise therapeutic intervention in acute inflammation.
• Overcoming pharmacokinetic and spatiotemporal limitations is key for effective vascular delivery.
• Nanomedicine and targeted therapeutics offer new perspectives for advanced management of inflammatory diseases.
