Cerebral navigation: How do nerve fibers know what direction to grow in?

Nervous system development requires billions of neurons to migrate to the appropriate locations in the brain and grow nerve fibers (axons) that connect to other nerve cells in an intricate network. Growth cones, structures in the tips of growing axons, are responsible for steering axons in the right direction, guided by a complex set of signals from cells they encounter along the way. Some signal...

Navigating the brain for sense of direction as paradigm for higher cognitive functions

No matter how healthy a life one leads, no person has managed to live much longer than a century. Even though the advances of the modern age may have extended the average human life span, it is clear there are genetic limits to longevity. One prominent theory of aging lays the blame on the accumulation of damage done to DNA and proteins by “free radicals,?highly reactive molecules produced by the...

Protein's role in regulating cell death sets direction for cancer research

A protein called calpain can be the key either preventing or promoting the cell death, a Queen's University study has found. "This work provides proof in principle that pharmacological inhibition of calpain may be used to block cell death in situations where this is not desirable, such as in neuronal cells of Alzheimer's or Parkinson's patients, but to promote cell death in cancer cells w...
