Neurobiologist Rodal wins New Innovator award
Date:9/14/2012

Chances are you didn't spend much time this morning getting your shoes on or thinking about which route you would take to work. But for people suffering with debilitating diseases such as ALS (Lou Gehrig's disease) or Alzheimer's, such simple functions -- and even activities like breathing and eating -- can be a struggle.

They are the people that Avital Rodal, assistant professor of biology, hopes to help through research that has just been funded by the National Institutes of Health. She hopes her work, which asks how neuronal firing affects transport of materials within neurons, will someday provide not only answers, but lead to solutions.

Rodal is one of the 51 NIH Director's New Innovator award recipients for 2012. The awards are given to researchers to pursue visionary science that exhibits the potential to transform scientific fields and speed the translation of research into improved health. The High Risk High Reward program is supported by the National Institutes of Health Common Fund. Rodal's lab will receive $300,000 per year for five years, plus additional research support costs for the university.

Rodal's lab works on how packets containing growth and survival signals are transported inside cells in membrane compartments. That is crucial for neurons, she says, as nerve cells can reach from the spinal cord all the way down to the toes.

"If you're a blue whale, that can be over 20 meters," says Rodal. " There is a whole highway system that packages these growth signals into little taxis that can then move along tracks that can bring them to another part of the neuron."

The body has multiple neurons that are in a relay from your brain to your spinal cord, then from your spinal cord to, say, your finger. Says Rodal, your finger is secreting growth factors, which stick to receptors on the membrane. Those receptors communicate back to the neuron by pinching in, so the membrane actually makes a little vesi
