The Regulation Of Chemokinesis By The Soil Amoeba, Dictyostelium Discoideum, Julia Horan
The Regulation Of Chemokinesis By The Soil Amoeba, Dictyostelium Discoideum, Julia Horan

Many types of cells crawl on solid surfaces by amoeboid locomotion. Membrane protrusions, such as pseudopods, are generated by outward directed forces and the cell body retracts to allow the cell to migrate on the surface. The movement can be random, or can be directional in response to diffusible (chemotaxis) or surface associated signals (haptotaxis). It has been known for some time that chemotactic signals also lead to an increase in overall cell speed (chemokinesis), however the mechanism of this speed increase is unknown. This project investigates the cellular signaling pathways involved in the regulation of cell speed by ligands …
Reconstitution Of Gabaergic Postsynapses In Host Cells, Karthik Kanamalla
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 …
The Effect Of Repeated Mild Traumatic Brain Injury On Ventricular Volume And Microglial Activation, Lillian Rose Talbot
The Effect Of Repeated Mild Traumatic Brain Injury On Ventricular Volume And Microglial Activation, Lillian Rose Talbot
Honors Scholar Theses
As the leading cause of death and disability in individuals under the age of 45-years-old, Traumatic Brain Injury (TBI) is a public health crisis that demands the attention of the scientific and medical community [28]. The majority of all TBIs that occur in the United States each year are a non-deadly yet detrimental form of closed brain injury known as mild TBI (mTBI) or concussion [6]. Athletes, young people and military personnel all face a high risk of acquiring mTBI as a result of their environments. In our study we have chosen to model repeated mTBI (rmTBI) in the mouse …
