High-resolution real-time images show in mice how nerves may be damaged during the earliest stages of multiple sclerosis. The results suggest that the critical step happens when fibrinogen, a blood-clotting protein, leaks into the central nervous system and activates immune cells called microglia.

The intensive glucose treatment was […]...
  3. Scientists find approach to enhance and prolong immune attack against tumor cells Investigators have identified a new class of human immune cells that behave like stem cells. These cells, a subtype of T lymphocytes, which comprise a small fraction of white blood cells, may prove more effective than any previously reported type of T cell for treating tumors. The study, by scientists at the National Cancer Institute […]...

Researchers design a light therapy that targets and destroys cancer cells in mice Researchers have designed a light-based therapy that allows the selective destruction of tumor cells in mice without harming surrounding normal tissue. This method of cancer therapy could theoretically work against tumors in humans, such as those of the breast, lung, prostate, as well as cancer cells in the blood such as leukemias, say scientists from […]...

MedicareCard.com, Experimental Immune, Boosting Drug Worsens TB in Mice An experimental drug that boosts production of the immune system protein interferon worsens tuberculosis (TB) in mice, according to scientists from the National Institutes of Health. The drug acts indirectly by drawing certain immune cells, in which Mycobacterium tuberculosis (M.tb) bacteria thrive, to the lungs. The findings may have potential implications for the care of people infected with TB, the authors note. The research is reported in the May 3 issue of Journal of Clinical Investigation, now available online....

Researchers develop mouse with ‘off switch’ in key brain cell population NIH-funded scientists have developed a strain of mice with a built-in off switch that can selectively shut down the animals’ serotonin-producing cells, which make up a brain network controlling breathing, temperature regulation, and mood. The switch controls only the serotonin-producing cells, and does not affect any other cells in the animal’s brains or bodies....
