    mice [17]. These data suggest a functional link between MT acetyla-tion patterns and brain aging, evidencing how the regulation of MT stability is critical during normal neuronal aging and supporting the concept that its failure may be a reliable candidate in causing neu-rodegenerative processes. Indeed, during the last years, an increasing. Is the Regulation of Microtubule Stability at the Crossroad Between Aging and Disease of Dopaminergic neurons? Over the time, it is becoming clear that microtubule system plays a fundamental role not only during the development of central nervous system but also during brain aging and neuronal death. In particular, the fine modulation of microtubule stability and tubulin .

This study showed protection of dopaminergic innervation of the striatum, improved motor performance, and gene expression for 8 menards.club by: The nigrostriatal pathway or nigrostriatal system transmits dopamine from the substantia nigra to the neostriatum. This is achieved by neurons that have their soma in the substantia nigra projecting axons out to the caudate nucleus and the putamen. It is involved in movement in a system called the Basal ganglia motor loop.
