Research

"Reserve your right to think, for even to think wrongly is better than not to think at all" - Hypatia of Alexandria, mathematician and philosopher (370 AD - 415 AD)

Neurons possess extensive tubulin post-translational modifications (PTMs) that are associated with microtubule (MT) longevity, and analyses of mammalian brain and cultured neurons demonstrate enrichment of detyrosinated, acetylated, poly-glutamylated and D2-tubulin subunits. These tubulin PTMs are implicated in the regulation of MT associated proteins (known as MAPs), MT severing enzymes, and binding to motors. Synaptic activation also locally regulates tubulin PTMs associated with MT stability. In addition to stable MTs, emerging studies indicate that dynamic MTs, typically deprived of tubulin PTMs, play key roles in neuronal function. Dynamic MTs polymerize from dendritic shafts into spines, and signaling through neurotransmitter receptors and local calcium entry regulate this process. Invasion of dendritic spines by dynamic MTs can in return affect spine morphology and function by regulating myosin- and kinesin-paired cargo dynamics. Furthermore, presynaptic dynamic MTs are necessary for the delivery of synaptic vesicles to their appropriate sites, and may mediate storage and/or docking /fusion of vesicles at the active zone. Thus, aside from their more conventional role in offering structural support to the neuron, MTs are fine regulators of neuronal homeostasis and synaptic function, and unwanted changes in MT dynamics, stability and/or tubulin PTMs may be involved in the onset of neurodegenerative and neuropathic disease by: ) impairing MT-dependent axonal and dendritic trafficking; 2) disrupting synaptic transmission; 3) interfering with the binding of MT severing enzymes and MAPs. My laboratory studies whether disruption of MT dynamicity and induction of tubulin PTMs is a general property of various neurodegenerative and neuropathic stimuli. In addition, we are particularly interested in the role of formins, a class of proteins with independent functions on the actin and MT cytoskeletons in regulating MT behavior downstream of neuropathogenic pathways. To tackle these questions, we employ biochemical and cell-biological approaches using immortalized non-neuronal cells, primary neuronal cultures and animal models of disease.
