DNA component can stimulate and suppress the immune response
A component of DNA that can both stimulate and suppress the immune system, depending on the dosage, may hold hope for treating cancer and infection, Medical College of Georgia researchers say. view more (2009-01-28)
Scientists develop fungus-fighting vaccine
group of scientists in Italy have developed a vaccine with the potential to protect against fungal pathogens that commonly infect humans, according to a study by Torosantucci and colleagues in the September 5 issue of The Journal of Experimental Medicine. view more (2005-09-06)
Keeping herpes infection in check: Pitt researchers describe immune system strategies
Herpes simplex virus type I can cause bouts of cold sores, blindness and potentially lethal encephalitis when it reawakens from a quiescent state in the nerve cells it infects. view more (2008-10-10)
Failed HIV Drug Gets Second Chance with Addition of Gold Nanoparticles
Researchers at North Carolina State University have discovered that adding tiny bits of gold to a failed HIV drug rekindle the drug's ability to stop the virus from invading the body's immune system. view more (2008-05-27)
Type 1 diabetes triggered by 'lazy' regulatory T-cells: McGill researchers
A research team led by Dr. Ciriaco A. Piccirillo of McGill University's Department of Microbiology and Immunology has discovered that in some individuals, the specialized immunoregulatory T-cells that regulate the body's autoimmune reactions may lose their effectiveness and become "lazy" over time, leading to the onset of type 1 diabetes. view more (2008-01-16)
Immunologists identify biochemical signals that help immune cells remember how to fight infection
Immunology researchers at UT Southwestern Medical Center have discovered how two biochemical signals play unique roles in promoting the development of a group of immune cells employed as tactical assassins. view more (2009-05-28)
Viral recombination another way HIV fools the immune system
When individuals infected with HIV become infected with a second strain of the virus, the two viral strains can exchange genetic information, creating a third, recombinant strain of the virus. It is known that the presence of multiple viral strains, called superinfection, frequently leads to a loss of immune control of viral levels. view more (2008-07-22)
Study gives clues about how deadly bacterium gains foothold
How a potentially deadly bacterium that could be used as a bioterrorist tool eludes being killed by the human immune system is now better understood. view more (2006-12-20)
New vaccine stimulates colorectal cancer patient's immune systems to fight cancerous cells
British researchers have developed a vaccine that stimulates colorectal cancer patients' immune systems to fight cancerous cells. view more (2006-11-15)
Thale cress goes on the defensive
Thale cress has a complicated defence technique against insects and microorganisms that use the plant as a source of food. view more (2007-05-15)
Indiana U scientists uncover potential key to better drugs to fight toxoplasmosis parasite
Discoveries by Indiana University School of Medicine scientists have opened a promising door to new drugs for toxoplasmosis and other parasites that now can evade treatments by turning dormant in the body. view more (2008-06-19)
Malaria parasite impairs key immune system cells
Plasmodium, the parasite responsible for malaria, impairs the ability of key cells of the immune system to trigger an efficient immune response. view more (2006-04-12)
IL-21 receptor plays an essential role in the Th2 immune response
During the immune response cells known as Th2 cells express a variety of cytokines (e.g. interleukin-4, -5, and -13), many of which stimulate B cells to proliferate and produce antibodies. view more (2006-06-16)
JDRF funded study links 'hygiene hypothesis' to diabetes prevention
A research study funded by JDRF suggests that a common intestinal bacteria may provide some protection from developing type 1 diabetes. The findings provide an important step towards understanding how and why type 1 diabetes develops in people, and may lead to potential cures. view more (2008-10-07)
Mayo Clinic boosts immune system
Mayo Clinic researchers have discovered a way to dramatically boost the output of immune system cells from the thymus, which may lead to improved cancer vaccines, as well as to ways to otherwise strengthen immune responses. view more (2005-09-23)
Research uncovers signaling pathways related to brain-immune system links
New research on signaling pathways in immune cells bolsters evidence of connections between the central nervous system and the immune system. view more (2006-05-16)
HIV pays a price for invisibility
Mutations that help HIV hide from the immune system undermine the virus's ability to replicate, show an international team of researchers in the April 13 issue of the Journal of Experimental Medicine. view more (2009-04-13)
Live From The Lymph Node
Scientists at the German Research Centre for Biotechnology (GBF) in Braunschweig have successfully filmed individual cells migrating within a functioning lymph node. "We are the first in Europe to have taken such pictures," explains GBF researcher Dr. Matthias Gunzer. The new findings gleaned from observing immune cells in action in a living... view more...

Mechanisms Involved with Tumor Relapse Identified
Researchers at Virginia Commonwealth University's Massey Cancer Center studying the interaction between the immune system and cancer cells have identified interferon gamma as one of the signaling proteins involved with tumor relapse. view more (2007-03-14)
Herpes: Scientists find cellular process that fights virus
Scientists have discovered a new way for our immune system to combat the elusive virus responsible for cold sores: Type 1 herpes simplex (HSV-1). As reported in the advance online edition of Nature Immunology, a group of virus hunters from the Université de Montréal, in collaboration with American colleagues, have identified a... view more...
