Breakthrough offers new hope in fight against global pandemic Scientists at the Gladstone Institutes have discovered new protein fragments in semen that enhance the ability of HIV, the virus that causes AIDS, to infect new cells–a discovery that one day could help curb the global spread of this deadly pathogen. HIV/AIDS has killed more than 25 million people around the world since first being identified some 30 years ago. In the United States alone, more than one million people...

Chronic infections by viruses such as HIV or hepatitis C eventually take hold because they wear the immune system out, a phenomenon immunologists describe as exhaustion. Yet exhausted immune cells can be revived after the introduction of fresh cells that act like coaches giving a pep talk, researchers at Emory Vaccine Center have found. Their findings provide support for an emerging strategy for treating chronic infections: infusing immune cells back into patients after a period of...

Research describes advantages of new vaccine adjuvant New research from the laboratory of Dr. Elizabeth Leadbetter at the Trudeau Institute may lead to a whole new class of vaccines. Dr. Leadbetter's lab has discovered new properties of a potential vaccine adjuvant that suggest it could be useful for enhancing protection against a number of different infections. This new data will be published in the January 2012 issue of the journal Nature Immunology (Vol. 13, pp. 44-50). The paper, "iNKT...

The findings could point the way to a new approach for treating malaria that does not rely on vaccination and is not susceptible to the parasite's notorious ability to develop drug resistance University of Iowa researchers and colleagues have discovered how malaria manipulates the immune system to allow the parasite to persist in the bloodstream. By rescuing this immune system pathway, the research team was able to cure mice of bloodstream malaria infections. The findings, which were...

Treatment with patients' own cells may prevent infections commonly seen following treatment and prolong remission A new treatment using leukemia patients' own infection-fighting cells appears to protect them from infections and cancer recurrence following treatment with fludarabine-based chemotherapy, according to new research from the Perelman School of Medicine at the University of Pennsylvania. The new process is a step toward eliminating the harsh side effects that result from the...

Traumatic brain injury is associated with a profound suppression of the patient's ability to fight infection. At the same time the patient also often suffers hyper-inflammation, due to the brain releasing glucocorticoids in response to the injury. New research published in BioMed Central's open access journal Critical Care shows that including probiotics with nutrients, supplied via the patient's feeding tube, increased interferon levels, reduced the number of infections, and even reduced the...

(Ivanhoe Newswire) — A rare type of HIV-infection -- group N -- has been diagnosed in a man in France who recently travelled to Togo, meaning that it has been detected outside Cameroon for the first time. This type of HIV infection is much more similar to the virus type found in chimpanzees than it is to other types circulating in humans. HIV in humans is usually group M, or less common, group O.  Since 1998 only 12 cases of group N, including two couples infected by the same...

Unexpected discovery of a new molecular signature for a destructive and often lethal pediatric liver disease may lead to a new therapeutic target for the hard-to-treat condition. In a study that included human livers and a mouse model of biliary atresia, researchers report in the November Journal of Clinical Investigation that not all children with biliary atresia share the same disease process. Some patients have a second molecular conductor of disease called Th2 (T helper cell 2) immune...
