Blood plasma protein fibrinogen interacts directly with nerve cells to cause brain inflammation

Neuroinflammatory diseases, including Alzheimer’s disease and traumatic brain injury, have been linked to deposits of a tough protein known as fibrin, derived from the blood clotting factor fibrinogen. These mesh-like fibrin deposits occur outside blood vessels in the brain, contributing to the death of certain central nervous system cells (neurons) that eventually leads to impaired

Metastases use divided blood vessels to grow

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 divides into two parallel vessels by longitudinal splitting. The finding

New eco-friendly solution to fight against malaria

Mosquitoes can and do feed on HMBPP-supplemented beetroot juice. This is the findings of a study at Stockholm University. HMBPP is a metabolite which is produced by Malaria parasite, Plasmodium. The researchers have shown that it is possible to mimic a blood meal so closely that mosquitoes naturally prefer this artificial solution by using HMBPP

New method visualizes blood flow in the brain down to one blood cell

Researchers from the Skolkovo Institute of Science and Technology and Saratov State University have come up with an inexpensive method for visualizing blood flow in the brain. The new technique is so precise it discerns the motions of individual red blood cells—all without the use of toxic dyeing agents or expensive genetic engineering. The study

Researcher receives $2.5 million award to curb HIV infection among people who inject drugs

International organizations and countries around the world are working to eliminate HIV/AIDS by 2030. To reach this goal, new approaches are needed–particularly among difficult-to-reach groups such as people who inject drugs (PWID), who are 30 times more likely to contract HIV/AIDS compared with the general population. Matthew Akiyama, M.D., assistant professor of medicine at Albert

Researchers unravel new mechanism that enables cancer development

Researchers at the University of North Carolina at Chapel Hill and the UNC Lineberger Comprehensive Cancer Center have uncovered a new mechanism that activates specific genes, leading to the development of cancers. They showed that a mutation that fuses two unrelated genes can promote a process similar to that observed when oil and water are
