Researchers find molecule that inhibits regrowth of spinal nerve cells

...lps the body's motor nerve cells grow along proper paths during embryonic development also plays a major role in inhibiting spinal-cord neurons from regenerating after injury, researchers at UT Southwestern Medical Center have found. In cultured cells, the researchers found that a component of myelin ?a su...

Bacteria are key to 'green' plastics, drugs

...one another. In fact, Bennett and San designed the paths to be complimentary, but even so, they were gratified to see how well the process worked once both paths were put in place. "Our experiments in the laboratory have produced near-maximum yields, with almos...

Can our genes tell the story of our divergence?

...umans and chimpanzees forged separate evolutionary paths some 5 million to 6 million years ago, we shed our hirsute coat and heavy brow, mastered bipedal locomotion, and acquired a knack for abstract thought while our next of kin learned to use tools, and developed the skills to construct tree-bound nests ...

Scientists identify new model Of NK cell development

...itor cells in the bone marrow ?they take different paths in developing into full-fighters in the immune system. For example, cells destined to become T cells, sophisticated and highly focused killer cells, are released into the bloodstream and migrate to the thymus where they learn their role. In contrast,...

Molecular machine may lead to new drugs to combat human diseases

...d paste genetic material is revealing possible new paths for treating diseases such as some forms of cancer and opportunistic infections that plague HIV patients. Purdue University researchers froze one of these molecular machines, which are chemical complexes known as a Group I intron, at mid-point in it...
