blood vessels

A recent study shows that a loss of antioxidants in the endothelial cells that line blood vessels in the lungs contributes to the loss of vasodilator effects and, ultimately, to the development of pulmonary hypertension.

The findings appear in Clinical and Translational Science.

(University of York) Scientists at the University of York have helped to reveal more about the way bacteria can attach to human tissues.

The researchers studied the way a protein found on the surface of the bacteria Staphylococcus aureus binds to a human protein called fibronectin.

Their discovery is an important step in understanding how bacteria attach to the surface of blood vessels during infection.

Researchers have found markers that indicate endothelial dysfunction (changes in the cells which line the blood vessels) and sub-clinical systemic inflammation can also help identify a far greater number of people at high risk for future development of type 2 diabetes.

Researchers have discovered new targets for cancer treatment aimed at blocking a key step in tumor progression. This step -- the creation of new blood vessels -- enables tumors to grow out of control and ultimately spread cancer to other parts of the body.

Hormone therapy may have different effects on blood vessels if it is started early in menopause as opposed to later, researchers suggest.

Tumors use the body's blood system for their own purposes: They stimulate the growth of blood vessels that supply the tumor.

Medical treatment blocks this process in order to restrain tumors. Scientists have now developed a method for producing a complex human vascular system in mice.

Researchers have discovered that blood vessels in the head can guide growing facial nerve cells with blood pressure controlling proteins.

The findings suggest that blood vessels throughout the body might have the same power of persuasion over many nerves.

The production of complex, multicellular tissues such as skin or blood vessels can now be envisaged, due to the development of a bioreactor with a "decoy effect." This novel, patented bioreactor enabling the culture and co-culture of cells of different types is a world first.

Researchers have discovered a way to control the growth rate of replacement tissue and the formation of new blood vessels, which solves one of the vexing problems of growing replacement tissue to treat injuries and trauma in humans.

Arsenic linked to a drug that binds to the blood vessels of cancerous tumors provides a powerful imaging agent that could one day allow physicians to detect hard-to-find tumors and more closely monitor cancer's response to therapy, researchers at UT Southwestern Medical Center have found.
