Third Wave scientists publish advance in gene expression monitoring with revolutionary RNA Invader Assay
...ithin a sample of closely related RNAs. RNA is the bodys
medium for translating an individuals genetic blueprint, found in ones DNA, into all the proteins in the body, including those that fight disease, metabolize drugs and perform a host of other critical functions. Many gene families, like the importan...

immune system to better fight leukemia. Taming c...e "graft vs. leukemia effect," IL-2 stimulates the bodys
natural killer cells to attack leukemia cells and drive the disease into remission. The pediatric...
Epimmune scientists report positive pre-clinical data on vaccine designed to combat HIV's ability to mutate
...ells (HTLs). Together, CTLs and HTLs comprise the bodys
natural defense against HIV in which CTLs are capable of directly destroying virus-infected cells but require HTLs, which produce immune-boosting chemicals, for proper functioning. Epimmune has designed its vaccine to provide immunity against many ...

Penn receives $1.2 million grant for further development of Compstatin, a drug to halt an overzealous immune system
(Philadelphia, PA) In some ways, the bodys
first line of defense can also be its worst enemy. The complement system is a series of biochemical reactions that activate in response to foreign molecules and is an important part of the immune system. Unfortunately, when it is activated at the wro...

Turning blood into brain: new studies suggest bone marrow stem cells can develop into neurons in living animals
...m a patients own body would not be rejected by the bodys
immune system. While the results are very promising, researchers need to answer many remaining questions before marrow-derived neural cell therapies can be tested in humans. A key question is what growth factors and other signals prompt the bone ...
ZymoGenetics researchers identify novel Interleukin that plays key role in immune system regulation
...oteins that appear to play a key role in the human bodys
ability to fight disease. These proteins, designated Interleukin 21 (IL-21) and Interleukin 21 receptor (IL-21R), are members of an important class of naturally-occurring cytokine ligand-receptor pairs that are involved in the growth and activation ...
