A structure called "the microtubule network" is a crucial part of our nervous system. It acts as a transportation system within nerve cells, carrying essential proteins and enabling cell-to-cell communications. But in neurodegenerative diseases like Alzheimer's, ALS, and Parkinson's, this network breaks down, hindering motor abilities and cognitive function.
Now Prof. Illana Gozes of Tel Aviv University's Sackler Faculty of Medicine has developed a new peptide in her lab, called NAP or Davunetide, that has the capacity to both protect and restore microtubule function. The peptide is a compound derived from the protein ADNP, which regulates more than 400 genes and is essential for brain formation, memory, and behavior.
Prof. Gozes and her team of researchers, including Dr. Yan Jouroukhin and graduate student Regin Ostritsky of TAU, observed that in animal models with microtubule damage, NAP was able to maintain or revive the transport of proteins and other materials in cells, ameliorating symptoms associated with neurodegeneration. These findings, which were reported in the journal Neurobiology of Disease, indicate that NAP could be an effective tool in fighting some of the most debilitating effects of neurodegenerative diseases.
Prof. Gozes is the director of TAU's Adams Super Center for Brain Studies and holds the Lily and Avraham Gildor Chair for the Investigation of Growth Factors.
Securing passage through the brain
In their investigation, the researchers used two different animal models with microtubule damage. The first group was made up of normal mice whose microtubule system was broken down through the use of a compound. The second group were genetically-engineered mouse models of ALS, in which the microtubule system was chronically damaged. In both groups, half the mice were given a single NAP injection, while the control half were not.
