Dendritic cells spark smoldering inflammation in smokers' lungs
What sparks that smoldering destruction remained a mystery until a consortium of researchers led by Baylor College of Medicine found that certain dendritic cells in the lung – the cells that "pre...

Read moreLarge-scale study probes how cells fight pathogens
Scientists have deciphered a key molecular circuit that enables the body to distinguish viruses from bacteria and other microbes, providing a deep view of how immune cells in mammals fend off differen...
Life Sciences | Read morePromising new target emerges for autoimmune diseases
University of Michigan scientists say they have uncovered a fundamentally new mechanism that holds in check aggressive immune cells that can attack the body’s own cells. The findings open a new avenue...
Life Sciences | Read moreTraffic jam in brain causes schizophrenia symptoms
Schizophrenia waits silently until a seemingly normal child becomes a teenager or young adult. Then it swoops down and derails a young life.Scientists have not understood what causes the sever...
Health and Medicine | Read moreScientists make multiple types of white blood cells directly from embryonic and adult stem cells
While clinical use is some years away, the new technique could produce cells with enormous potential for studying the development and treatment of disease. The technique works equally well with stem c...

It takes a spleen to mend a broken heart – that's the conclusion of a surprising new report from researchers at the Massachusetts General Hospital (MGH) Center for Systems Biology, directed by Ra...
Life Sciences | Read moreStudy may explain why HIV progresses faster in women than in men with same viral load
One of the continuing mysteries of the HIV/AIDS epidemic is why women usually develop lower viral levels than men following acute HIV-1 infection but progress faster to AIDS than men with similar vira...
Studies and Analyses | Read moreNatural suppressors of a treatment-induced disease
Researchers in Japan have shown that mouse dendritic cells (DCs), which can promote or inhibit inflammation depending on the proteins displayed on their surface, include a subpopulation that exerts be...
Life Sciences | Read moreStudy identifies biomarker that safely monitors tumor response to new brain cancer treatment
The finding, reported in the July 1 issue of Clinical Cancer Research, paves the way for a Phase 1 clinical trial expected to begin in late 2009. The gene therapy is a two-pronged strategy dev...
Life Sciences | Read moreNew fuel cell catalyst uses 2 metals
Material scientists at Washington University in St. Louis have developed a technique for a bimetallic fuel cell catalyst that is efficient, robust and two to five times more effective than commercial ...

“There’s no little man sitting there, putting the protein in the right place,” said Don Arnold, a molecular and computational biologist at USC College.“Proteins have to have in them encoded in...
Life Sciences | Read moreDendritic cells ensure immune tolerance
The only way to protect against these afflictions is to destroy all immune factors that turn against the body’s own tissue – in other words: immune tolerance. A team working with LMU researche...
Life Sciences | Read moreTB breakthrough could lead to stronger vaccine
Bacille Calmette-Guérin (BCG) provides only partial protection against tuberculosis (TB) in children and is ineffective in adults. As a result, tuberculosis still kills almost 2 million people a year ...
Health and Medicine | Read moreIncreased understanding of immune system activation
To understand how different materials are taken up and what happens within the cells can for example facilitate the development of new vaccines."The immune system is a large and important...
Life Sciences | Read moreNew origin found for a critical immune response
"This finding will have important implications in vaccine science and autoimmune disease therapy development," said Michael Gunn, M.D., an immunologist and cardiologist at Duke and senior au...
