Intussusceptive angiogenesis contributes to growth of daughter tumors in malignant melanoma

For the first time, researchers at the University of Gothenburg have shown that metastases in patients with malignant melanoma gain access to the circulatory system not only through the outgrowth of new blood vessel branches, but also an alternative process in which one blood vessel divide into two parallel vessels bylongitudinal splitting.

Novel research reveals a vital but previously unknown role for microglia

University of Virginia School of Medicine researchers have revealed a vital but previously unknown role for immune cells that protect the brain from disease and injury: The cells, known as microglia, also help regulate blood flow and maintain the brain's critical blood vessels.

Researchers use photosynthetic microbes as an oxygen source for nerve cells

Each second, the nerve cells in the brain process numerous signals. And the energy needed to carry out these tasks is mostly generated by aerobic metabolism—the reason why the brain needs a constant supply of oxygen.

Scientists provide insights on immune evasion of metastatic cancer cells in lymph nodes

Lymph nodes are critical to the body's immune response against tumors but paradoxically, cancer cells that spread, or metastasize, to lymph nodes can often avoid being eliminated by immune cells.

Study reveals the basis of oxygenation fluctuations in brain

The brain is supplied with sufficient nutrients and oxygen due to the blood flow; however, the oxygenation is likely to fluctuate distinctly and uniformly.
