Mechanism of mitochondrial complex I damage in brain ischemia/reperfusion injury. A hypothesis
Publication date: Available online 5 September 2019Source: Molecular and Cellular NeuroscienceAuthor(s): Vadim Ten, Alexander GalkinAbstractThe purpose of this review is to integrate available data on the effect of brain ischemia/reperfusion (I/R) on mitochondrial complex I. Complex I is a key component of the mitochondrial respiratory chain and it is the only enzyme responsible for regenerating NAD+ for the maintenance of energy metabolism. The vulnerability of brain complex I to I/R injury has been observed in multiple animal models, but the mechanisms of enzyme damage have not been studied. This review summarizes old an...

A disintegrin and metalloproteinase with thrombospondin motifs 2 cleaves and inactivates Reelin in the postnatal cerebral cortex and hippocampus, but not in the cerebellum
Publication date: Available online 3 September 2019Source: Molecular and Cellular NeuroscienceAuthor(s): Yuko Yamakage, Michinao Kato, Aya Hongo, Himari Ogino, Keisuke Ishii, Takumi Ishizuka, Takana Kamei, Hitomi Tsuiji, Tomomi Miyamoto, Hisashi Oishi, Takao Kohno, Mitsuharu HattoriAbstractReelin plays important roles in regulating neuronal development, modulating synaptic function, and counteracting amyloid β toxicity. A specific proteolytic cleavage (N-t cleavage) of Reelin abolishes its biological activity. We recently identified ADAMTS-3 (a disintegrin and metalloproteinase with thrombospondin motifs 3) as the major N...

Role of fast inhibitory synaptic transmission in neonatal respiratory rhythmogenesis and pattern formation
Publication date: Available online 28 August 2019Source: Molecular and Cellular NeuroscienceAuthor(s): Michael George Zaki Ghali, Sarah BeshayAbstractSeveral studies have investigated the general role of chloride-based neurotransmission (GABAA and glycinergic signaling) in respiratory rhythmogenesis and pattern formation. In several brain regions, developmental alterations in these signaling pathways have been shown to be mediated by changes in cation-chloride cotransporter (CC) expression. For instance, CC expression changes over the neonatal period in medullary respiratory nuclei and other brain/spinal cord regions in a ...

PlexinD1 and Sema3E determine laminar positioning of heterotopically projecting callosal neurons
In this study, we showed that the axon guidance receptor PlexinD1 is expressed by a large proportion of heterotopically projecting CPNs in layer 5A of the primary somatosensory (S1) and motor (M1) areas. Retrograde tracing of M1 CPNs projecting to the contralateral striatum revealed the presence of ectopic neurons aberrantly located in layers 2/3 of Plxnd1 and Sema3e mutant cortices. These results showed that Sema3E/PlexinD1 signalling controls the laminar distribution of heterotopically projecting CPNs. (Source: Molecular and Cellular Neuroscience)

TDP-43 proteinopathy and mitochondrial abnormalities in neurodegeneration
Publication date: Available online 21 August 2019Source: Molecular and Cellular NeuroscienceAuthor(s): Ju Gao, Luwen Wang, Tingxiang Yan, George Perry, Xinglong WangAbstractGenetic mutations in TAR DNA-binding protein 43 (TDP-43) cause amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Importantly, TDP-43 proteinopathy, characterized by aberrant phosphorylation, ubiquitination, cleavage or nuclear depletion of TDP-43 in neurons and glial cells, is a common prominent pathological feature of various major neurodegenerative diseases including ALS, FTD, and Alzheimer's disease (AD). Although the pathomechan...

Gamma secretase modulators and BACE inhibitors reduce Aβ production without altering gene expression in Alzheimer's disease iPSC-derived neurons and mice
Publication date: Available online 2 August 2019Source: Molecular and Cellular NeuroscienceAuthor(s): Carlo Cusulin, Isabelle Wells, Solveig Badillo, Gonzalo Christian Duran Pacheco, Karlheinz Baumann, Christoph PatschAbstractIn drug discovery, as well as in the study of disease biology, it is fundamental to develop models that recapitulate aspects of a disorder, in order to understand the pathology and test therapeutic approaches. Patient-derived induced pluripotent stem cells (iPSCs) offer the potential of obtaining tissue-specific cells with a given human genotype. Here we derived neural cultures from Alzheimer's diseas...

PLD1 promotes dendritic spine morphogenesis via activating PKD1
Publication date: Available online 26 July 2019Source: Molecular and Cellular NeuroscienceAuthor(s): Wen-Qi Li, Li-Da Luo, Zhi-Wen Hu, Tian-Jie Lyu, Cheng Cen, Yun WangAbstractDendritic spines on the dendrites of pyramidal neurons are one of the most important components for excitatory synapses, where excitatory information exchanges and integrates. The defects of dendritic spine development have been closely connected with many nervous system diseases including autism, intellectual disability and so forth. Based on our previous studies, we here report a new functional signaling link between phospholipase D1 (PLD1) and pro...
