Scientists at The Vision Centre have found new evidence that the common blinding disease macular degeneration (MD) may result from poorly regulated immune responses similar to those linked to Alzheimer's disease or cerebral haemorrhages. The leading cause of vision loss and blindness in Australia, macular degeneration often occurs as a result of the immune system going into overdrive and killing more vision cells than it should, according to new evidence found by PhD student Matt Rutar from...

Gladstone investigators solve long-standing HIV mystery Scientists at Gladstone Institute of Virology and Immunology have solved a long-standing mystery about HIV infection"“namely how HIV promotes the death of CD4 T cells. It is the loss of this critical subset of immune cells that leads to the development of AIDS. Most immune cells that die during HIV infection are seemingly not infected, a phenomenon formerly described as "bystander cell killing." Now the Gladstone scientists report...

White blood cells called neutrophils are part of the body's first line of defense against bacterial infection. Neutrophils are recruited from the bloodstream to infected tissues where they release powerful chemicals that kill bacteria and amplify the immune response. These cells function as first responders at the scene of infection and often have a short life span. As a result, new neutrophils are produced continuously from stem cells in the bone marrow. Previous research has suggested that...

Scientist also successfully visualises, in a living cell culture, how the immune cells colonise the brain Findings could lead to new strategies to treat various brain disorders 1. A team of international scientists led by Dr Florent Ginhoux of the Singapore Immunology Network (SIgN) of Singapore's Agency of Science, Technology and Research (A*STAR), have made a breakthrough that could lead to a better understanding of many neurodegenerative and inflammatory brain disorders. Their work,...

A new study reveals that two enzymes help immune cells deploy pathogen-killing traps by unraveling and using the chromatin (DNA and its associated proteins) contained in the cells' nuclei to form defensive webs. The study appears online on October 25 in The Journal of Cell Biology (www.jcb.org). Neutrophils, the most common type of white blood cells, are difficult to study because they live for only about six hours. So Arturo Zychlinsky and colleagues, from the Max Planck Institute for...

research published in Science Researchers at the University of Calgary Faculty of Medicine are using an innovative new imaging technique to study how white blood cells (called neutrophils) respond to inflammation, and have revealed new targets to inhibit the response. When the body is invaded by infection, the immune system counters by generating inflammation with deployment of white blood cells to the site of danger to kill invading bacteria. However, inappropriate inflammation occurs in the...

Cigarette smoke shuts off a key enzyme in airways that regulates the body's response to inflammation, according to findings from the University of Alabama at Birmingham published online today at Science Express. The UAB researchers say smoke inhibits the enzyme, called Leukotriene A4 Hydrolase (LTA4H), causing it to fail in its job of shutting down white blood cells following a successful response to inflammation. The team says the research study identified a previously unknown substrate of...

Mushrooms are among the many foods thought to play an important role in keeping the immune system healthy. Now, Agricultural Research Service (ARS)-funded scientists have conducted an animal-model and cell-culture study showing that white button mushrooms enhanced the activity of critical cells in the body's immune system. In the United States, white button mushrooms represent 90 percent of the total mushrooms consumed. The study was conducted at the Jean Mayer USDA Human Nutrition Research...

Scientists at the Virginia Bioinformatics Institute (VBI) at Virginia Tech have constructed a mathematical and computational model of inflammatory bowel disease that allows researchers to simulate the cellular and molecular changes underlying chronic inflammation in humans. The model allows scientists to explore different interactions of cells in the immune system, check how these cells are linked to inflammation in the colon, and identify intervention points to perhaps stop the disease in...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
