New lab mice pave way for novel studies of human infection
A new type of laboratory mouse developed at UT Southwestern Medical Center can fight certain infections the same way humans do, making the rodents very useful for novel studies of human-pathogen interaction and developing disease therapies. view more (2006-10-23)
Using insects to test for drug safety
Insects, such as some moths and fruit flies, react to microbial infection in the same way as mammals and so can be used to test the efficiency of new drugs, thereby reducing the need for animal testing. view more (2009-09-08)
DNA of good bacteria drives intestinal response to infection
A new study shows that the DNA of so-called "good bacteria" that normally live in the intestines may help defend the body against infection. view more (2008-10-03)
Bacteria 'launch a shield' to resist attack
Researchers from the University of Copenhagen and the Technical University of Denmark along with other collaborators in Denmark and the US found that the bacterium Pseudomonas aeruginosa can 'switch on' production of molecules that kill white blood cells - preventing the bacteria being eliminated by the body's immune system. view more (2009-11-02)
Penn study finds a new role for RNA in human immune response
Researchers at the University of Pennsylvania School of Medicine have published the first study to test the role of RNA chemical modifications on immunity. view more (2005-08-24)
UT Knoxville research may lead to better flu vaccine
New research from a scientist at the University of Tennessee, Knoxville, has uncovered information that may someday lead to a better flu vaccine. view more (2008-02-28)
Implants mimic infection to rally immune system against tumors
Bioengineers at Harvard University have shown that small plastic disks impregnated with tumor-specific antigens and implanted under the skin can reprogram the mammalian immune system to attack tumors. view more (2009-01-23)
Natural immune-control system may aid treatment of autoimmune disease and tissue rejection
The immune system's ability to police itself may offer a new method of arresting the cells responsible for autoimmune diseases such as multiple sclerosis and for the rejection of transplanted organs and tissues. view more (2007-05-18)
What is the function of lymph nodes?
If we imagine our immune system to be a police force for our bodies, then previous work has suggested that the Lymph nodes would be the best candidate structures within the body to act as police stations - the regions in which the immune response is organised. view more (2009-05-26)
How HIV vaccine might have increased odds of infection
In September 2007, a phase II HIV-1 vaccine trial was abruptly halted when researchers found that the vaccine may have promoted, rather than prevented, HIV infection. view more (2008-11-03)
Weight loss after gastric bypass surgery may protect against infection and cancer
Another health benefit of bariatric weight-loss surgery may be a heightened immune defense against cancer and infections, a new study suggests. The results will be presented at The Endocrine Society's 90th Annual Meeting in San Francisco. view more (2008-06-18)
Gene therapy protocol at UCSD activates immune system in patients with leukemia
A research team at the Moores Cancer Center at University of California, San Diego (UCSD) reports that patients with chronic lymphocytic leukemia (CLL) who were treated with a gene therapy protocol began making antibodies that reacted against their own leukemia cells. view more (2008-02-12)
Previously unknown immune cell may help those with Crohn's and colitis
The tonsils and lymphoid tissues in the intestinal tract that help protect the body from external pathogens are the home base of a rare immune cell newly identified by researchers at Washington University School of Medicine in St. Louis. view more (2008-11-04)
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)
Potential autoimmunity-inducing cells found in healthy adults
It's not just patients with autoimmune diseases like lupus and rheumatoid arthritis (RA) that have self-attacking immune cells-healthy people have them too, according to a new report in the Journal of Experimental Medicine. view more (2008-12-22)
UGA researchers one step closer to cancer vaccine
When cells become cancerous, the sugars on their surfaces undergo distinct changes that set them apart from healthy cells. For decades, scientists have tried to exploit these differences by training the immune system to attack cancerous cells before they can spread and ravage the body. view more (2007-10-30)
Study shows how herpes infects cornea, evades immune cells
Herpes virus has an unusual strategy for infecting cornea cells that may also explain how it evades the immune system, according to a study by researchers at the University of Illinois at Chicago College of Medicine. view more (2006-09-26)
Commonly used antidepressants may also affect human immune system
Drugs that treat depression by manipulating the neurotransmitter serotonin in the brain may also affect the user's immune system in ways that are not yet understood, say scientists from Georgetown University Medical Center and a Canadian research institute. view more (2006-01-20)
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)
HIV infection requires an accomplice: B cells with special protein direct HIV to T cells
HIV infection of T cells requires activation of a molecule on the surface of B cells, a finding that reveals yet another pathway the virus uses in its insidious attack on the immune system. view more (2006-08-14)
