Regulatory Roles Of Mical-L1 And Ehd1 In Cell Signaling And Mitosis, James B. Reinecke Dec 2015

Regulatory Roles Of Mical-L1 And Ehd1 In Cell Signaling And Mitosis, James B. Reinecke

Theses & Dissertations

Membrane trafficking is a basic cell biological process that controls the distribution of proteins and lipids. Our lab is particularly interested in delineating the cellular functions as well as the molecular mechanisms that regulate the C-terminal Eps15 Homology Domain (EHD) protein family of adenosine-5’-triphosphatases in mammalian cells. EHD1-4 are ubiquitously expressed in mammalian tissues and serve partially overlapping but also distinct functions in regulating membrane shaping and fission along the endocytic pathway. Specifically, EHD1 is recruited to tubular recycling endosomes (TREs) by Molecule Interacting with CasL Like-1 (MICAL-L1) and facilitates TRE fission and release of cargo from the perinuclear endocytic …


The Role Of Glutaminase 1 In Hiv-1 Associated Neurocognitive Disorders And In Brain Development, Yi Wang Aug 2015

The Role Of Glutaminase 1 In Hiv-1 Associated Neurocognitive Disorders And In Brain Development, Yi Wang

Theses & Dissertations

Glutaminase is the enzyme that converts glutamine into glutamate, which serves as a key excitatory neurotransmitter and one of the energy providers for cellular metabolism. Glutamate is essential for proper brain functioning but at excess levels, it is neurotoxic and has a key role in the pathogenesis of various neurodegenerative diseases, including HIV-1 associated neurocognitive disorders (HAND). However, the detailed mechanism of glutamate-mediated neurotoxicity remains unclear. In part I, we identified the regulation of glutaminase 1 (GLS1) in the central nervous system (CNS) of HAND animal models including HIV-Tat transgenic (Tg) mouse and HIVE-SCID mouse, since GLS1 is the dominant …
