by Columbia University Irving Medical Center Children and adults produce different types and amounts of antibodies in response to infection with the new coronavirus, SARS-CoV-2, a new study from researchers at Columbia University Vagelos College of Physicians and Surgeons has found. The differences in antibodies suggest the course of the infection and immune response is distinct in children and most...
By Sally Robertson, B.Sc.,Nov 4 2020 A new study has shown that the extent to which social distancing restrictions and face mask usage could be relaxed in the United States during the coronavirus disease 2019 (COVID-19) pandemic would greatly depend on how effective a vaccine is and the proportion of the population it covered. The...
Changing makeup of a specific protein has the potential to neutralize the virus. Researchers from McGill University are part of an international team led by the University of Buffalo, which has discovered a technique that could help increase the effectiveness of vaccines against SARS-CoV-2, the virus that causes COVID-19. The group’s study was published recently online...
IDIBELL-BELLVITGE BIOMEDICAL RESEARCH INSTITUTE IMAGE: CASANOVAS TEAM Angiogenesis is the process by which tumors create new blood vessels that will provide them the nutrients to continue growing. Antiangiogenic drugs specifically block this process. This type of therapy usually has good short-term results, reducing tumor growth. However, several studies suggest that these treatments increase the invasiveness of tumors,...
by Max Planck Society Oligodendrocytes wrap around the axon of a nerve cell. In this way, they form an electrical insulation layer around the axon and thus increase the conduction speed. The oligodendrocytes also supply the neuron with energy. In a conversation, we can easily understand and distinguish individual words. In the brain, the temporal structure...
UNIVERSITY OF COLORADO AT BOULDER A new University of Colorado Boulder-led study sheds light on a protein key to controlling how cells grow, proliferate and function and long implicated in tumor development. The findings, published this week in the journal Genes and Development, could lead not only to new therapies for hard-to-treat cancers, but also inform...
MAX DELBRÜCK CENTER FOR MOLECULAR MEDICINE IN THE HELMHOLTZ ASSOCIATION IMAGE: A 3D VIEW OF THE BRAIN VENTRICLES OF A STUDY PARTICIPANT. It is not only the heart that has chambers – the brain does, too. Its four ventricles are connected to the spinal canal and filled with a clear liquid called cerebrospinal fluid, which...
UNIVERSITY OF CAMBRIDGE Scientists have used gene therapy to regenerate damaged nerve fibres in the eye, in a discovery that could aid the development of new treatments for glaucoma, one of the leading causes of blindness worldwide. Axons – nerve fibres – in the adult central nervous system (CNS) do not normally regenerate after injury...
by Thomas Jefferson University The purified oligodendrocyte extracellular vesicles under an electron microscope. Multiple sclerosis (MS) is an autoimmune disorder that develops as the body’s immune system attacks the central nervous system. Specifically, it attacks the protective layer surrounding nerve cells, called the myelin sheath. Current MS therapies aim to counter this inflammatory response by suppressing...
by Johns Hopkins University School of Medicine In a small study of adults with major depression, Johns Hopkins Medicine researchers report that two doses of the psychedelic substance psilocybin, given with supportive psychotherapy, produced rapid and large reductions in depressive symptoms, with most participants showing improvement and half of study participants achieving remission through the four-week follow-up. A...
