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...

Immune system cells called macrophages spring into action to surround and destroy threats such as viruses or cancer cells. But sometimes the would-be protective response leads to persistent inflammation, which, in turn, can cause disease. Scientists don't know exactly how macrophages cross the line from being good cops to bad cops, but researchers at the University of Florida recently unearthed several clues about the mechanisms involved. Through the lens of two inflammation-related diseases,...

New research published in the Journal of Leukocyte Biology suggests bortezomib induces cell death in activated and proliferating T cells, leaving resting T cells untouched, offering hope for reducing or eliminating dangerous inflammation Those looking for a new treatment for a range of inflammatory diseases like arthritis, multiple sclerosis, inflammatory bowel disease, and lupus may need to look no further than a drug already available for treating cancer. In a research report published in...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
