#7 - The Role Of Rnf216/Triad3 In Neuroinflammation Through Interactions With Toll-Like-Receptors, Dustin Grossman

Georgia Undergraduate Research Conference (GURC)

Ubiquitin E3 ligases are enzymes that mark certain substrates with ubiquitin proteins which leads to different cellular fates. Ring finger protein 216 (RNF216) is a ubiquitin E3 ligase that is involved in synaptic plasticity, inhibiting cellular autophagy, and the immune response in the peripheral nervous system. Previous literature has demonstrated that RNF216 participates in various aspects of inflammation by regulating ubiquitination and proteasomal degradation of receptor-interacting serine-threonine kinase 1 (RIPK1), toll-interleukin 1 receptor domain containing adaptor protein (TIRAP), and TIR-domain-containing adapter-inducing interferon-β (TRIF), targeting TNF receptor associated factor 3 (TRAF3) for degradation. TLRs initiate signal transduction pathways which can lead ...

Altered sensory processing in response to novel DREADD-induced inactivation of GABA in pedunculopontine tegmental nucleus

Background: Sensory processing deficits are associated with certain psychiatric illnesses, such as schizophrenia and autism spectrum disorder (ASD). Sensory filtering and sensorimotor gating are evolutionarily conserved preattentive responses that filter and block redundant sensory stimuli that would otherwise overwhelm our brains. To date, underlying mechanisms of these deficits are undefined. Prepulse inhibition (PPI) of the ...


Analysis Of Mitochondrial Turnover In Neuromuscular Junctions Of Parkin Mutants, Kenny Nguyen, Hyun Sung, Peter J. Hollenbeck Aug 2015

Analysis Of Mitochondrial Turnover In Neuromuscular Junctions Of Parkin Mutants, Kenny Nguyen, Hyun Sung, Peter J. Hollenbeck

The Summer Undergraduate Research Fellowship (SURF) Symposium

The accumulation of dysfunctional or damaged mitochondria in neurons has been linked to the pathogenesis of many neurodegenerative diseases, such as Parkinson’s disease. It has been proposed that proteins PINK1 and Parkin regulate mitochondrial quality control by selectively targeting depolarized mitochondria for autophagic degradation, a process known as mitophagy. Though previously analyzed in the cell bodies and axons of neurons, the role of the PINK1/Parkin pathway in the synapse is unclear, and it is not known whether mitochondrial turnover occurs in the neuromuscular junctions (NMJs). To study this, intact Drosophila nervous systems were analyzed in vivo by performing ...
