Listeria, one of the most deadly causes of bacterial food poisoning, subverts a normally protective immune response to spread its infection more effectively, according to new research at National Jewish Health. Immunologists Laurel Lenz, PhD, Peter Henson, PhD, and their colleagues report online April 26, 2012, in the journal Immunity that production of nitric oxide (NO) by activated macrophages, which is normally thought of as an infection-fighting response, actually helps Listeria...

BBSRC-funded researchers at Cambridge University have shed new light on a common food poisoning bug. Using real-time video microscopy, coupled with mathematical modeling, they have changed our assumptions about Salmonella and how it infects human cells. The research was published in Interface. Salmonella is an important bacterium to study as it causes a range of diseases in humans and animals. It is capable of growing and reproducing inside macrophages - a type of white blood cell that...

The characterisation of a rare immune cell´s involvement in antibody production and ability to ℠remember´ infectious agents could help to improve vaccination and lead to new treatments for immune disorders, say researchers from the Walter and Eliza Hall Institute. The cells, called T follicular helper cells, represent less than half of one per cent of all immune cells, but play a critical role in antibody production and developing long-lasting immunity. However, the cells...

Finding may help develop new treatments for infectious diseases, cancer UCLA researchers pinpointed a new mechanism that potently activates T-cells, the group of white blood cells that play a major role in fighting infections. Published March 25 online in Nature Medicine, the team specifically studied how dendritic cells, immune cells located at the site of infection, become more specialized to fight the leprosy pathogen known as Mycobacterium leprae. Dendritic cells, like scouts in the...

An inexpensive new medical sensor has the potential to simplify the diagnosis of diseases ranging from life-threatening immune deficiencies to the common cold, according to its inventors at the Stanford University School of Medicine. Their device, called an integrated microfluidics-waveguide sensor, sorts and counts cells in small samples of blood and other body fluids. The developers say the sensor provides an easy way to measure different types of white blood cells, a key component of...

Very recently, researchers discovered an important population of immune cells called memory T cells living in parts of the body that are in contact with the environment (e.g., skin, lung, GI tract). How these "resident" memory T cells are generated was unknown, and their importance with regard to how our immune system remembers infection and how it prevents against re-infection is being studied intensively. Now, a study by a Brigham and Women's Hospital (BWH) research team led by Xiaodong...

University of Texas Medical Branch at Galveston researchers have discovered previously unsuspected aspects of the guidance system used by the body's first line of defense against infection. The new work focuses on the regulation of immune response by two forms of the signaling molecule IL-8, as well as IL-8's interaction with cell-surface molecules called glycosaminoglycans (or GAGs for short). Infected or injured tissues release IL-8 to attract bacteria- and virus-killing white blood...

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...
