A new study turns the well established theory that antibodies are required for antiviral immunity upside down and reveals that an unexpected partnership between the specific and non-specific divisions of the immune system is critical for fighting some types of viral infections. The research, published online on March 1st in the journal Immunity by Cell Press, may lead to a new understanding of the best way to help protect those exposed to potentially lethal viruses, such as the rabies virus....

These new data are an essential step towards understanding the operation of these key cells in the immune system, and they could provide a new therapeutic approach to fighting infection. They also suggest that the operation of NK cells must be precisely regulated to guarantee an optimum immune reaction. Details of this work are published in the 20 January 2012 issue of the journal Science. Our bodies are subject to attack by many different infectious particles (bacteria, viruses, etc.),...

A central element of the immune system has remained constant through more than 400 million years of evolution, according to new research at National Jewish Health. In the September 29, 2011, online version of the journal Immunity, the researchers report that T-cell receptors from mice continue to function even when pieces of shark, frog and trout receptors are substituted in. The function of the chimeric receptors depends on a few crucial amino acids, found also in humans, that help the...

Researchers at Johns Hopkins have modified HIV in a way that makes it no longer able to suppress the immune system. Their work, they say in a report published online September 19 in the journal Blood, could remove a major hurdle in HIV vaccine development and lead to new treatments. "Something about the HIV virus turns down the immune response, rather than triggering it, making it a tough target for vaccine development," says David Graham, Ph.D., assistant professor of molecular and...

St. Jude Children's Research Hospital scientists provide insight into immune system biology and identify the mechanism that keeps white blood cell activity at a minimum until the specific immune response is needed St. Jude Children's Research Hospital scientists have identified a key immune system regulator, a protein that serves as a gatekeeper in the white blood cells that produce the "troops" to battle specific infections. Researchers demonstrated the protein, Tsc1, is pivotal for...
