New research may guide creation of targeted, more effective vaccines A new understanding of a certain cell in the immune system may help guide scientists in creating better flu vaccines, report researchers from the Program in Cellular and Molecular Medicine and the Immune Disease Institute at Children's Hospital Boston (PCMM/IDI). Reporting online March 21 in Nature Immunology, they show, for the first time, that white blood cells known as resident dendritic cells (DCs) capture flu viruses...

As much as half the world's population has less than adequate immune systems where their killer T cells cannot fight infection properly, and scientists find that vitamin D is a vital key to keeping their defenses up. Danish researchers have found that vitamin D could help with the fight against infectious diseases and worldwide epidemics, and could be very useful in finding new vaccines, they said. The researchers found that T cells in people's immune systems rely on vitamin D to become...

Innovative strategy could be effective against other chronic viral diseases Researchers from the UCLA AIDS Institute and colleagues have for the first time demonstrated that human blood stem cells can be engineered into cells that can target and kill HIV-infected cells "” a process that potentially could be used against a range of chronic viral diseases. The study, published Dec. 7 in the-peer reviewed online journal PLoS ONE, provides proof-of-principle "” that is, a...

The right kind of stress response in the operating room could lead to quicker recovery for patients after knee surgery, according to a new study led by Stanford University School of Medicine researchers. The results could be used to develop methods for predicting how well patients will fare after they leave the hospital. The study, conducted with colleagues at Yale University and to be published Dec. 1 in the Journal of Bone and Joint Surgery, found that patients whose immune systems...

Fox Chase researchers uncover process that determines the fate of white blood cells Like an unusually forceful career counselor, the Id3 protein decides the fate of a given white blood cell precursor, according to researchers at Fox Chase Cancer Center. Their findings, published today in the journal Immunity, describe how Id3 directs blood cell progenitors to become gamma-delta T cells. Gamma-delta T cells are unique in that they possess attributes of both the adaptive arm of the immune...

Specific cells within the immune system could help explain why younger people are more susceptible to variant CJD, scientists believe Specific cells within the immune system could help explain why younger people are more susceptible to variant CJD, scientists believe. Patients diagnosed with variant CJD are, on average, 28 years old but it has been unclear why older people are not as affected by the disease. Research at The Roslin Institute of the University of Edinburgh has identified...

Researchers from Brown University and McGill University have discovered that the natural killer, or NK cells, help prevent T cells from over-responding when a virus hits. This balance helps prevent T cells, which ordinarily serve the immune system, from causing harm. Details are in the September issue of The Journal of Experimental Medicine. Natural killer, or NK cells, are part of our innate immune system. A healthy body produces them to respond early during infection. They are activated and...

After more than 50 experiments in mice, medical scientists at Johns Hopkins have mapped out the basic steps taken by a particular set of white blood cells in setting the pace of recovery after serious lung injury. The white blood cells are called regulatory T cells, or Tregs for short, and their best known function is to keep the body's immune system from attacking its own healthy tissues. "Our study results are the critical first leads in finding treatments for a clinical condition that...

Disease mechanism in HIV infection decoded / Heidelberg virologists publish in "Cell Host & Microbe" In order to be able to ward off disease pathogens, immune cells must be mobile and be able to establish contact with each other. The working group around Professor Dr. Oliver Fackler in the Virology Department of the Hygiene Institute of the Heidelberg University Hospital has discovered a mechanism in an animal model revealing how HIV, the AIDS pathogen, cripples immune cells: Cell...

X-linked lymphoproliferative disease (XLP) is a rare inherited immunodeficiency most commonly caused by deficiency in the protein SAP. Following infection with the common virus that causes infectious mononucleosis (also known as mono or glandular fever), boys with XLP often develop an extreme, usually fatal, accumulation of activated immune cells known as cytotoxic T lymphocytes; but the mechanistic link between this and SAP deficiency has not been determined. However, Michael Lenardo and...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
