In astrocytes and microglia, MPEP depletes ATP. These ﬁndings seem to be self-contradictory, since ATP depletion is a fundamental stressor in ischemia. This study attempted to reconstruct the mechanism of MPEP-mediated ATP depletion and the consequences of ATP depletion on protection against ischemic injury. We compared the effects of MPEP and other mGluR5 negative modulators on ATP concentration when measured in rat hepatocytes and acellular solutions. We also evaluated the effects of mGluR5 blockade on viability in rat hepatocytes exposed to hypoxia. Furthermore, we studied the effects of MPEP treatment on mouse livers subjected to cold ischemia and warm ischemia reperfusion.

Metabotropic Glutamate Receptors
mGluR Metabotropic glutamate receptors mGluR (metabotropic glutamate receptor) is a type of glutamate receptor that are active through an indirect metabotropic process. They are members of thegroup C family of G-protein-coupled receptors, or GPCRs. Like all glutamate receptors, mGluRs bind with glutamate, an amino acid that functions as an excitatoryneurotransmitter. The mGluRs perform a variety of functions in the central and peripheral nervous systems: mGluRs are involved in learning, memory, anxiety, and the perception of pain. mGluRs are found in pre- and postsynaptic neurons in synapses of the hippocampus, cerebellum, and the cerebral cortex, as well as other parts of the brain and in peripheral tissues. Eight different types of mGluRs, labeled mGluR1 to mGluR8, are divided into groups I, II, and III. Receptor types are grouped based on receptor structure and physiological activity. www.MedChemExpress.com 1 mGluR Agonists, Antagonists, Inhibitors, Modulators & Activators (-)-Camphoric acid (1R,2S)-VU0155041 Cat.

Combining in vitro and in vivo 29 activation of mGluR5 in rats, we identify specific changes in intrinsic excitability and 30 synaptic plasticity in basolateral amygdala neurons that give rise to temporally distinct 31 and mutually exclusive effects on fear-related behaviors. The immediate impact of 32 mGluR5 activation is to produce anxiety manifested as indiscriminate fear of both tone 33 and context. Surprisingly, this state does not interfere with the proper encoding of tone- 34 shock associations that eventually lead to enhanced cue-specific fear. These results 35 provide a new framework for dissecting the functional impact of amygdalar mGluR- 36 plasticity on fear versus anxiety in health and disease.

Abstract Crosstalk between both pre- and post-synaptic components of glutamatergic neurotransmission plays a crucial role in orchestrating a multitude of brain functions including synaptic plasticity and motor planning. Metabotropic glutamate receptor 5 (mGluR5) exhibits a promising therapeutic potential for many neurodevelopmental and neurodegenerative disorders, as the consequence of its modulatory control over diverse neuronal networks required for memory, motor coordination, neuronal survival and differentiation.

Proteostasis of Glial Intermediate Filaments: Disease Models, Tools, and Mechanisms
PROTEOSTASIS OF GLIAL INTERMEDIATE FILAMENTS: DISEASE MODELS, TOOLS, AND MECHANISMS Rachel Anne Battaglia A dissertation submitted to the faculty at the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Cell Biology and Physiology in the School of Medicine. Chapel Hill 2021 Approved by: Natasha T. Snider Carol Otey Keith Burridge Douglas Cyr Mohanish Deshmukh Damaris Lorenzo i © 2021 Rachel Anne Battaglia ALL RIGHTS RESERVED ii ABSTRACT Rachel Anne Battaglia: Proteostasis of Glial Intermediate Filaments: Disease Models, Tools, and Mechanisms (Under the direction of Natasha T. Snider) Astrocytes are a major glial cell type that is crucial for the health and maintenance of the Central Nervous System (CNS). They fulfill diverse functions, including synapse formation, neurogenesis, ion homeostasis, and blood brain barrier formation. Intermediate filaments (IFs) are components of the astrocyte cytoskeleton that support many of these functions in healthy individuals. However, upon cellular stress or genetic mutations, IF proteins are prone to accumulation and aggregation. These processes are thought to contribute to disease pathogenesis of different tissue-specific disorders, but therapeutic targeting of IFs is hindered by a lack of pharmacological tools to modulate their assembly and disassembly states. Moreover, the mechanisms that govern the formation and dissolution of IF aggregates are poorly defined. In this dissertation, I investigate IF aggregates called Rosenthal fibers (RFs), which form in astrocytes of patients with two pediatric neurodegenerative diseases, Alexander disease (AxD) and Giant Axonal Neuropathy (GAN). My aim was to gain a better understanding of the mechanisms of how astrocyte IF protein aggregates form and interrogate the role of post- translational modifications (PTMs) in this process.
