(Ivanhoe Newswire) — A hopeful new way to block tumor growth!  According to a study, the key mechanism that causes the spread of cancer has been identified and can lead to blocking tumor findings. Lead researcher, David Waisman, Ph.D, professor in the Departments of Biochemistry and Molecular Biology and Pathology, and Canada Research Chair in Cancer Research at Dalhousie University, have detailed the key role the macrophage cell, white blood cells in tissue, specific surface...

Vision scientists have identified a key player in macular degeneration (MD), raising hope for a treatment for the currently incurable blinding disease. The studies reveal how light-damaged eyes invoke an out-of-control immune response, resulting in white blood cells invading the retina and leaving behind proteins that kill the light sensitive vision cells. This type of immune attack is seen in macular degeneration, which accounts for half of the vision loss cases in Australia, costing the...

Targeting the neuroinflammatory causes of Parkinson's disease with a naturally present brain chemical signal could offer a better understanding of the clinical mechanisms of the disease and open a future therapeutic window, reports a team of researchers from the University of South Florida Department Neurosurgery and Brain Repair and the James A. Haley Veterans' Administration Hospital, Tampa. Their findings are published online in the Journal of Neuroinflammation...

USF researchers find CD45 blocks early AD developmental step in mouse model A new target for the prevention of adverse immune responses identified as factors in the development of Alzheimer's disease (AD) has been discovered by researchers at the University of South Florida's Department of Psychiatry and the Center of Excellence for Aging and Brain Repair. Their findings are published online in the Journal of Neuroscience (http://www.jneurosci.org/). The CD45 molecule is a receptor on the...

A gene from the measles virus plays a key role in the development of Paget's disease of bone, according to a team of researchers led by the University of Pittsburgh School of Medicine. Their findings, recently published in Cell Metabolism, confirm a long-held speculation that the childhood infection is an environmental trigger for the disease and reveal how the viral gene contributes to the development of its characteristic bone lesions. "Our earlier work showed that bone cells called...

A paper published online on January 10 in the Journal of Experimental Medicine reports that retinal ganglion cells"”neurons in the eye"”are rescued by immune cells that infiltrate the mouse retina after eye injury. A group led by Michal Schwartz at the Weizmann Institute detected immune cells called macrophages in the retinas of mice that sustained eye injuries a few days prior. Thanks to their expression of an anti-inflammatory protein, these macrophages dampened injury-induced...

Most cancer tissues are invaded by inflammatory cells that either stimulate or inhibit the growth of the tumor, depending on what immune cells are involved. Now a Swedish-Belgian research team has shown that a protein that naturally occurs in the body, HRG, inhibits tumor growth and metastasis into secondary organs by activating specific immune cells. The study is being published today in the Net edition of the prestigious journal Cancer Cell. - Our study shows that the regulation of...

For the first time, scientists have described not only the identities and quantities of fat species in a living mammalian cell "“ in this case, a mouse macrophage or white blood cell "“ but they also report how these lipids react and change over time to a bacterial stimulus triggering the cell's immune response. Writing in the December 17 issue of the Journal of Biological Chemistry, lead author Edward A. Dennis, PhD, distinguished professor of pharmacology, chemistry and...

Immune cells known as microglia, long thought to be activated in the brain only when fighting infection or injury, are constantly active and likely play a central role in one of the most basic, central phenomena in the brain "“ the creation and elimination of synapses. The findings, publishing next week in the online, open access journal PLoS Biology, catapult the humble microglia cell from its well-recognized duty of protecting the brain to direct involvement in creating the cellular...

Once, scientists and doctors thought we were born with a certain number of neurons and those had to last us throughout our lifespan. Today, neurologists know that new neurons can be produced in adulthood. These adult hippocampal newborn neurons arise in the hippocampus, an area of the brain responsible for learning and memory. Understanding how these neurons live and die could answer questions about diseases that affect learning and memory said Dr. Amanda Sierra Saavedra, a postdoctoral...
