Immunomodulation and Vascular Remodeling Mechanisms

The coordinated interplay between the immune system and vascular compartments underpins both physiological vessel maintenance and pathological remodelling. Endothelial cells, smooth muscle cells and extracellular matrix collectively respond to immunological cues that range from acute injury to chronic inflammation. Innate immune effectors, notably neutrophils and monocyte‐derived macrophages, are first responders to endothelial disruption, clearing debris and secreting proteases and cytokines that shape the early remodelling milieu. Subsequently, dendritic cells and lymphocyte subsets orchestrate adaptive responses that may either resolve inflammation or perpetuate lesion growth. Dysregulated immune activation drives neointimal hyperplasia, a hallmark of atherosclerosis, restenosis and graft vasculopathy, by promoting smooth muscle cell proliferation, migration and phenotypic switching. Conversely, regulatory T cells and tolerogenic antigen‐presenting cells release anti‐inflammatory mediators such as interleukin-10 and transforming growth factor β to restrain pathological remodelling and foster vessel repair. At the molecular level, chemokines, adhesion molecules and growth factors create spatial gradients that guide immune cell trafficking and matrix deposition. Novel insights into the crosstalk between metabolic pathways, redox signalling and immune checkpoints reveal additional layers of control over vessel wall integrity. Understanding these immunomodulatory networks is central to developing targeted therapies—ranging from drug‐eluting devices and small molecules to biomimetic nanoparticles—that aim to mitigate vascular disease while preserving essential host defence.
