Pathophysiology of Vascular Remodeling in Hypertension

Vascular remodeling refers to alterations in the structure of resistance vessels contributing to elevated systemic vascular resistance in hypertension. We start with some historical aspects, underscoring the importance of Glagov's contribution. We then move to some basic concepts on the biomechanics of blood vessels and explain the definitions proposed by Mulvany for specific forms of

Endothelial Repair and Regeneration Following Intimal

The balance between endothelial damage and repair is critical for the maintenance of intimal integrity, function, and prevention of thrombotic complications. This review will discuss on the aftereffects of intravascular device implants on endothelial injury and the pathways involved in endothelial repair and regeneration with an emphasis on endothelial progenitor cells.

Apoptosis mechanisms and clinical implications Kam

Briefly, the cell shrinks and detaches from neighbouring cells and the nucleus is broken down. The nuclear fragments and organelles condense and are ultimately packaged in membrane‐bound vesicles, exocytosed and ingested by surrounding cells. Membrane integrity is preserved and dyes are only taken up late in the process. The absence of inflammation differentiates apoptosis

Chronic obstructive pulmonary disease (COPD) is commonly associated with vascular changes in the pulmonary and systemic circulations. Pulmonary muscular arteries characteristically show intimal hyperplasia, which is produced in part by the proliferation of poorly differentiated smooth muscle cells. The origin of these cells has not been determined.

T lymphocytes inhibit the vascular response to pnas

The proliferation of vascular smooth muscle cells is controlled by specific growth factors and cytokines acting in paracrine networks. Macrophage products such as the platelet-derived growth factor and interleukin 1 promote smooth muscle proliferation and are released in the arterial wall during atherosclerosis and repair processes. T lymphocytes are also present in vascular tissue,
