New research has identified a small subset of normal white blood cells in the body that gives rise to a rare incurable form of leukemia. The study, led by investigators at The Ohio State University Comprehensive Cancer Center "“ Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC "“ James), shows that large granular lymphocyte leukemia can occur in a small subset of white blood cells called NKT cells. NKT cells share features of immune cells called T...

New research published in the Journal of Leukocyte Biology suggests that histamine plays an important role as an immune modulator, which could be a significant finding for multiple sclerosis research If you think histamines are your nemesis during allergy season, here's something that might change your perspective. New research published in the Journal of Leukocyte Biology (http://www.jleukbio.org) shows that histamine could be an important molecule to developing new treatments for multiple...

HIV's Trickery within the Macrophage Revealed HIV adapts in a surprising way to survive and thrive in its hiding spot within the human immune system, scientists have learned. While the finding helps explain why HIV remains such a formidable foe after three decades of research "“ more than 30 million people worldwide are infected with HIV "“ it also offers scientists a new, unexpected way to try to stop the virus. The work by researchers at the University of Rochester Medical...

(Ivanhoe Newswire) -- For the first time ever it is shown that human fetal immune system arises from a completely different source than the adult immune system, and is more likely to tolerate than fight foreign substances in its environment. This finding could lead to a better understanding of how newborns respond to infections and vaccines, and may explain some mysteries as to why many infants of HIV-positive mothers are not infected with the disease before birth. In addition, it could help...

Fast-moving objects create blurry images in photography, and the same challenge exists when scientists observe cellular interactions within tissues constantly in motion, such as the breathing lung.  In a recent UCSF-led study in mice, researchers developed a method to stabilize living lung tissue for imaging without disrupting the normal function of the organ. The method allowed the team to observe, for the first time, both the live interaction of living cells in the context of their...

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...
