Dragonfly's metabolic disease provides clues about human obesity

... high-performance flight. "These guys are the jet fighters of the insect world," said Marden. Flight muscle makes up 60 percent of their body mass. The large variation in muscle output was intriguing because natural selection, over time, would weed out the submissive, poor flyers if the trait were genetica...

Science researchers genetically transform immune cells into tumor fighters

...is in mind, Rosenberg and colleagues created tumor fighters by removing normal T cells from people with advanced metastatic melanoma, genetically engineering these normal cells to carry the receptor that recognizes melanoma cells and returning these "re-armed" cells to rebuild the patients' immune systems. ...

White blood cells of cancer-resistant mice overwhelm natural defenses of cancer cells

...ls of so many different types. The dogma of cancer fighters has always postulated that there are many different cancers. "This new research in mice suggests that there may be some things that most cancers have in common," said Willingham, a pathologist and head of the Section on Tumor Biology. ...

Cracking open the black box of autoimmune disease

...of the regulatory T cells to control the frontline fighters leads to autoimmune disease. Scientists previously discovered that regulatory T cells are themselves controlled by a master gene regulator called Foxp3. Master gene regulators bind to specific genes and control their level of activity, which in t...

Molecule that destroys bone also protects it, new research shows

...r cells in the vicinity to recruit these infection fighters to the infection site," Gaffen said. IL-17 is a cytokine, a protein hormone made by "T helper" cells of the immune system that stimulate immunity. Gaffen noted that until recently, immunologists believed there were only two major types of "T helpe...
