The Role Of Protease-Activated Receptor-1 In Synaptic Plasticity And Memory, Antoine Gabriel Almonte
The Role Of Protease-Activated Receptor-1 In Synaptic Plasticity And Memory, Antoine Gabriel Almonte
All ETDs from UAB
Protease-activated receptor-1 (PAR1) is an unusual G-protein coupled receptor (GPCR) that is activated through proteolytic cleavage by extracellular serine proteases. While previous work has shown that inhibiting PAR1 activation is neuroprotective in models of ischemia, traumatic injury, and neurotoxicity, surprisingly little is known about PAR1's contribution to normal brain function. In the central nervous system (CNS), PAR1 is expressed in glial cells in the hippocampus, a brain region critical for memory formation. I am particularly interested in PAR1 because its activation enhances the function of N-methyl-D-aspartate receptors (NMDARs), which are required for some forms of behavioral learning and synaptic plasticity. …
Torsina And The Pathophysiology Of Dyt1 Dystonia, Yu Zhao
Torsina And The Pathophysiology Of Dyt1 Dystonia, Yu Zhao
Theses and Dissertations (ETD)
The goal of my dissertation work was to examine the systems biology of torsinA, a DYT1 dystonia-associated protein, by using rodent model systems. TorsinA is a putative ATPase associated with a variety of cellular activities (AAA+). Deletion of glutamic acid residue 302/303 in TOR1A is causally associated with many cases of early-onset primary dystonia.
In our work, transient forebrain ischemia and sciatic nerve transection were used as central and peripheral neural perturbations, respectively, to gain insight into the in vivo role(s) of torsinA. Moreover, transgenic mouse models that overexpress either human mutant torsinA (hMT) or wild-type torsinA (hWT) were used …
