Protein Glutamylation: From Cytoskeleton to Signaling

Med Research, EarlyView.
Tubulin glutamylation, γ‐glutamylation, and nontubulin glutamylation are distinct yet interconnected post‐translational modifications that regulate diverse physiological and pathological processes, including cytoskeletal organization, cell cycle progression, immunity, metabolism, and disease development.

The Plasma Membrane Ca2+-ATPase2 (PMCA2) Is Involved in the Regulation of Purkinje Cell Dendritic Growth in Cerebellar Organotypic Slice Cultures

Neural Plasticity, 2013
Purkinje cells are the principal neurons of the cerebellar cortex and have an extensive and elaborate dendritic tree. Chronic activation of type I metabotropic glutamate receptors inhibits Purkinje cell dendritic growth in organotypic cerebellar slice ...

Eph/ephrin Function Contributes to the Patterning of Spinocerebellar Mossy Fibers Into Parasagittal Zones

Frontiers in Systems Neuroscience, 2020
Purkinje cell microcircuits perform diverse functions using widespread inputs from the brain and spinal cord. The formation of these functional circuits depends on developmental programs and molecular pathways that organize mossy fiber afferents from ...

Early Longitudinal Brain Network Changes in Huntington's Disease Before Clinical Motor Onset

Movement Disorders, EarlyView.
Abstract Background Longitudinal studies of seed‐based functional connectivity (SBFC) in young adult Huntington's disease gene‐expanded (HDGE) individuals are rare, and none, to our knowledge, have examined adult cohorts decades from predicted clinical motor diagnosis.

Expanded ATXN3 CAG Repeat is Stable in Human Purkinje Cells

Movement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia type 3 (SCA3) is a neurodegenerative disorder caused by an abnormally long polyglutamine‐encoding CAG repeat in the ATXN3 gene. Objectives We aimed to determine whether somatic expansion of the mutant ATXN3 (mATXN3) CAG repeat is present in the output cell of the cerebellar cortex, the Purkinje cell (PC), in ...

Structural Brain and Spinal Cord Signature of Spinocerebellar Ataxia 27B: A Multisite MRI‐Based Study

Movement Disorders, EarlyView.
Abstract Background SCA27B is a recently described ataxia, the precise anatomical basis of which remains unclear. Objective The goal was to characterize the structural brain and spinal cord magnetic resonance imaging (MRI) signature of spinocerebellar ataxia 27B (SCA27B) using multimodal quantitative imaging.

Regularity, variabilty and bi-stability in the activity of cerebellar Purkinje cells

Frontiers in Cellular Neuroscience, 2009
Recent studies have demonstrated that the membrane potential of Purkinje cells is bi-stable and that this phenomenon underlies bi-modal simple spike firing.

Deletion of the GluR delta 2 Receptor in the Hotfoot Mouse Mutant Causes Granule Cell Loss, Delayed Purkinje Cell Death, and Reductions in Purkinje Cell Dendritic Tree Area

, 2016
International audienceRecent studies have found that in the cerebellum, the delta 2 glutamate receptor (GluR delta 2) plays a key role in regulating the differentiation of parallel fiber-Purkinje synapses and mediating key physiological functions in the ...

Distinctly altered TRPC3 and TRPC6 expression patterns in human Alzheimer's disease cortex and hippocampus

Brain Pathology, EarlyView.
Divergent remodeling of TRPC channels occurs in Alzheimer's disease, with TRPC3 increased in neurons and reactive astrocytes and TRPC6 reduced in pyramidal neurons. These alterations may contribute to calcium dysregulation, neuroinflammation, and synaptic dysfunction during AD progression.
