The blood-brain barrier is a crucial protection mechanism: It is a highly selective physical barrier that prevents pathogens and toxins in the circulatory system from entering the central nervous system where they could create ...

Arteriogenesis is a critical event - not only during development but also in adult life. Cardiovascular life-threatening events, triggered by disease, could be overcome by alternatives to existing therapies, for example by ...

By studying the effects of immune cells that surround blood vessels in the brain, Weill Cornell Medicine researchers have discovered a new pathway involving these cells that may contribute to the cause of Alzheimer's disease.

Osaka University researchers show endothelial cells are vulnerable to bacterial infection because they lack certain immune machinery common in other cells.

Vasoconstriction must be balanced with vasodilation, particularly in the arterioles that supply tissues with blood. Endothelial cells protrude through holes in the internal elastic lamina in arterioles to make contact with ...

The endothelial cells that comprise blood vessels are uniquely responsive to cues from other organs, since their role is to integrate intimately into tissues and provide a means for delivery of oxygen and nutrients and waste ...

While it's widely held that tumors can produce blood vessels to support their growth, scientists now have evidence that cells key to blood vessel formation can also produce tumors and enable their spread.

Approximately 80% of all sensory input is received via the eyes, so suffering from chronic retinal diseases that lead to blindness causes a significant decrease in the quality of life (QOL). And because retinal diseases are ...

Delivering drugs to the brain is no easy task. The blood-brain barrier -a protective sheath of tissue that shields the brain from harmful chemicals and invaders - cannot be penetrated by most therapeutics that are injected ...

The endothelium is the thin layer of cells that line the interior surface of blood vessels, forming an interface between circulating blood in the lumen and the rest of the vessel wall. Endothelial cells line the entire circulatory system, from the heart to the smallest capillary. These cells reduce turbulence of the flow of blood allowing the fluid to be pumped farther.
Endothelial tissue is a specialized type of epithelium tissue (one of the four types of biological tissue in animals). More specifically, it is simple squamous epithelium.
