Epileptic Mechanisms Shared by Alzheimer's Disease
International Journal of Molecular Sciences Review Epileptic Mechanisms Shared by Alzheimer’s Disease: Viewed via the Unique Lens of Genetic Epilepsy Jing-Qiong Kang 1,2 1 Department of Neurology & Pharmacology, Vanderbilt University Medical Center, Nashville, TN 37232-8552, USA; [email protected]; Tel.: +1-615-936-8399; Fax: +1-615-322-5517 2 Vanderbilt Kennedy Center of Human Development, Vanderbilt Brain Institute, Vanderbilt University, Nashville, TN 37232-8522, USA Abstract: Our recent work on genetic epilepsy (GE) has identified common mechanisms between GE and neurodegenerative diseases including Alzheimer’s disease (AD). Although both disorders are seemingly unrelated and occur at opposite ends of the age spectrum, it is likely there are shared mechanisms and studies on GE could provide unique insights into AD pathogenesis. Neurodegen- erative diseases are typically late-onset disorders, but the underlying pathology may have already occurred long before the clinical symptoms emerge. Pathophysiology in the early phase of these diseases is understudied but critical for developing mechanism-based treatment. In AD, increased seizure susceptibility and silent epileptiform activity due to disrupted excitatory/inhibitory (E/I) balance has been identified much earlier than cognition deficit. Increased epileptiform activity is likely a main pathology in the early phase that directly contributes to impaired cognition. It is an enormous challenge to model the early phase of pathology with conventional AD mouse models due to the chronic disease course, let alone the complex interplay between subclinical nonconvulsive epileptiform activity, AD pathology, and cognition deficit. We have extensively studied GE, especially with gene mutations that affect the GABA pathway such as mutations in GABAA receptors and GABA transporter Citation: Kang, J.-Q. -
(PRRT2) Regulates the Actin Cytoskeleton During Synaptogenesis
Savino et al. Cell Death and Disease (2020) 11:856 https://doi.org/10.1038/s41419-020-03073-w Cell Death & Disease ARTICLE Open Access Proline-rich transmembrane protein 2 (PRRT2) regulates the actin cytoskeleton during synaptogenesis Elisa Savino1,2, Romina Inès Cervigni1,2, Miriana Povolo1,2, Alessandra Stefanetti2, Daniele Ferrante3, Pierluigi Valente3,4, Anna Corradi3,4, Fabio Benfenati 4,5, Fabrizia Claudia Guarnieri1,2 and Flavia Valtorta 1,2 Abstract Mutations in proline-rich transmembrane protein 2 (PRRT2) have been recently identified as the leading cause of a clinically heterogeneous group of neurological disorders sharing a paroxysmal nature, including paroxysmal kinesigenic dyskinesia and benign familial infantile seizures. To date, studies aimed at understanding its physiological functions in neurons have mainly focused on its ability to regulate neurotransmitter release and neuronal excitability. Here, we show that PRRT2 expression in non-neuronal cell lines inhibits cell motility and focal adhesion turnover, increases cell aggregation propensity, and promotes the protrusion of filopodia, all processes impinging on the actin cytoskeleton. In primary hippocampal neurons, PRRT2 silencing affects the synaptic content of filamentous actin and perturbs actin dynamics. This is accompanied by defects in the density and maturation of dendritic spines. We identified cofilin, an actin-binding protein abundantly expressed at the synaptic level, as the ultimate effector of PRRT2. Indeed, PRRT2 silencing unbalances cofilin activity leading to the formation of cofilin-actin rods along neurites. The expression of a cofilin phospho-mimetic mutant (cof-S3E) is able to rescue PRRT2-dependent defects in synapse 1234567890():,; 1234567890():,; 1234567890():,; 1234567890():,; density, spine number and morphology, but not the alterations observed in neurotransmitter release. -

Glomerular development has been analyzed mainly in mice, whereas analysis of human kidney development has been minimal because of limited access to embryonic kidneys. We previously reported the induction of three-dimensional primordial glomeruli from human induced pluripotent stem (iPS) cells. Here, using transcription activator–like effector nuclease-mediated homologous recombination, we generated human iPS cell lines that express green fluorescent protein (GFP) in the NPHS1 locus, which encodes nephrin, and we show that GFP expression facilitated accurate visualization of nephrin-positive podocyte formation in -
The Prion Protein Regulates Synaptic Transmission by Controlling the Expression of Proteins Key to Synaptic Vesicle Recycling and Exocytosis

To explore possible molecular contributions of PrPC to synaptic transmission, we utilized a mass spectrometry approach to quantify the release of glutamate from primary cerebellar granule neurons (CGN) expressing, or deprived of (PrP-KO), PrPC, following a depolarizing stimulus. Under the same conditions, we also tracked recycling of synaptic vesicles (SVs) in the two neuronal populations. We found that in PrP-KO CGN these processes decreased by 40 and 60%, respectively, compared to PrPC-expressing neurons. Unbiased quantitative mass spectrometry was then employed to compare the whole proteome of CGN with the two PrP genotypes. This approach allowed us to assess that, relative to the PrPC-expressing counterpart, the absence of PrPC modified the protein expression profile, including diminution of some components of SV recycling and fusion machinery. Subsequent quantitative RT-PCR closely reproduced proteomic data, indicating that PrPC is committed to ensuring optimal synaptic transmission by regulating genes involved in SV dynamics and neurotransmitter release. -
