Scientists at the University Medical Center in Mainz prove multiple DNA repair defect in monocytes Scientists working with Professor Bernd Kaina of the Institute of Toxicology at the Medical Center of Johannes Gutenberg University Mainz have demonstrated for the first time that certain cells circulating in human blood — so-called monocytes — are extremely sensitive to reactive oxygen species (ROS). They were also able to clarify the reason for this: ROS are aggressive forms of...

New research published in the Journal of Leukocyte Biology suggests that certain strains of Pseudomonas aeruginosa cause white blood cells to produce high levels of histamine, which worsens the severity of inflammation and infection Could some cases of asthma actually be caused by an allergic reaction to a common environmental bacteria? New research findings published in the Journal of Leukocyte Biology (https://www.jleukbio.org) suggests that this idea may not be as far-fetched as it...

Leukemic cutaneous T-cell lymphoma (L-CTCL) is a leukemia arising from T-cells, a type of white blood cell. This cancer can involve the skin and other organs, and patients often die within three years. Rachael A. Clark, MD, PhD, BWH assistant professor of dermatology and associate dermatologist and Thomas Kupper, MD, BWH Department of Dermatology chairman and their colleagues now report a new study that low-dose Campath (alemtuzumab) not only treats patients with L-CTCL but does so without...

New research published in the Journal of Leukocyte Biology suggests that high levels of estradiol present prior to ovulation decreases immune system effectiveness resulting in growth and promotion of infection A new research report in the Journal of Leukocyte Biology (http://www.jleukbio.org) suggests that a woman's ovarian cycle plays an important role in her susceptibility to infection. Specifically, researchers from Spain and Austria found that women are most susceptible to infection,...

Chronic infections by viruses such as HIV or hepatitis C eventually take hold because they wear the immune system out, a phenomenon immunologists describe as exhaustion. Yet exhausted immune cells can be revived after the introduction of fresh cells that act like coaches giving a pep talk, researchers at Emory Vaccine Center have found. Their findings provide support for an emerging strategy for treating chronic infections: infusing immune cells back into patients after a period of...

Researchers at the University of Toronto have found an explanation for how the intestinal tract influences a key component of the immune system to prevent infection, offering a potential clue to the cause of autoimmune disorders like rheumatoid arthritis and multiple sclerosis. "The findings shed light on the complex balance between beneficial and harmful bacteria in the gut," said Prof. Jennifer Gommerman, an Associate Professor in the Department of Immunology at U of T, whose findings...

Hydrogen peroxide isn't just that bottled colorless liquid in the back of the medicine cabinet that's used occasionally for cleaning scraped knees and cut fingers. It's also a natural chemical in the body that rallies at wound sites, jump-starting immune cells into a series of events. A burst of hydrogen peroxide causes neutrophils, the immune system's first responders, to rush to the wound to fight microorganisms, remove damaged tissue and then start the inflammation process....

The stealth art of infectious agents: Researchers uncover why the body can't defend against tuberculosis Tuberculosis, which kills over 2 million people each year, is caused primarily by infectious bacteria known as Mycobacterium tuberculosis — or Mtb. Mtb targets human immune cells as part of its strategy to avoid detection, effectively neutralizing the body's immune response. Up until now, scientists had a general understanding of the process, but researchers in the Immunity and...

New research published in the Journal of Leukocyte Biology demonstrates that elevated body temperature plays a vital role on the generation of effective T-cell mediated immune response With cold and flu season almost here, the next time you're sick, think twice before taking something for your fever. That's because scientists have found more evidence that elevated body temperature helps certain types of immune cells to work better. This research is reported in the November 2011 issue of...

How our skin says, 'Don't worry, these are good guys,' revealed today in PNAS There are more bacteria living on our skin and in our gut than cells in our body. We need them. But until now no-one knew how the immune system could tell that these bacteria are harmless. Centenary Institute researchers in Sydney have discovered a set of peacekeepers–immune cells in the outer layers of our skin that stop us from attacking friendly bacteria. The work will open the way to new...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
