Reconstitution Of Gabaergic Postsynapses In Host Cells, Karthik Kanamalla
Honors Scholar Theses
Type A GABA receptors (GABAARs) can be found embedded in postsynaptic membranes or in a variety of extrasynaptic locations. Receptors with synaptic function are recruited to the postsynapse by submembranous scaffolds composed of gephyrin and collybistin (CB). This study was aimed at assessing whether the ability to interact with the scaffold differentiates synaptic from non-synaptic receptors. Using HEK293 cells as an expression system, and indirect immunofluorescence (IF), co-localization of extrasynaptic receptors α1β3δ and α4β3δ with the CB-gephyrin scaffold was assessed and compared with that of the synaptic receptor α1β3γ2. Results indicated that both extrasynaptic receptors were able to colocalize with …

Direct Reprogramming Of Mouse Embryonic Fibroblasts Into Gabaergic Neurons, Nicholas J. Wasko
Honors Scholar Theses
Recent studies in which mouse and human fibroblasts were directly reprogrammed into functional neurons have demonstrated that lineage-specific transcription factors can override differentiation processes previously thought to be irreversible. Notably, three factors have been shown to be required for the induction of neural cell fate. Subsequent experiments have identified additional factors capable of generating specific neuronal subtypes, including motor neurons and dopaminergic neurons, but the factors necessary for inducing GABAergic neuronal fate have yet to be elucidated. Here, factors linked to GABAergic fate were transfected into mouse fibroblasts in order to identify candidate factors for inhibitory interneuron direct reprogramming. Results …
