[PDF][PDF] Neuroligin 2 drives postsynaptic assembly at perisomatic inhibitory synapses through gephyrin and collybistin

A Poulopoulos, G Aramuni, G Meyer, T Soykan… - Neuron, 2009 - cell.com
In the mammalian CNS, each neuron typically receives thousands of synaptic inputs from
diverse classes of neurons. Synaptic transmission to the postsynaptic neuron relies on …

Subcellular transcriptomes and proteomes of developing axon projections in the cerebral cortex

A Poulopoulos, AJ Murphy, A Ozkan, P Davis, J Hatch… - Nature, 2019 - nature.com
The development of neural circuits relies on axon projections establishing diverse, yet well-defined,
connections between areas of the nervous system. Each projection is formed by …

[HTML][HTML] BRI2 interacts with amyloid precursor protein (APP) and regulates amyloid β (Aβ) production

…, M Tsachaki, M Vlavaki, A Poulopoulos… - Journal of Biological …, 2005 - ASBMB
Transmembrane proteins BRI2 and amyloid precursor protein (APP) co-localize with amyloid
β (Aβ) lesions in sporadic Alzheimer disease and mutations in both precursor proteins are …

Increased dentate gyrus excitability in neuroligin-2-deficient mice in vivo

…, A Vlachos, R Winkels, A Poulopoulos… - Cerebral …, 2011 - academic.oup.com
The postsynaptic adhesion protein neuroligin-2 (NL2) is selectively localized at inhibitory
synapses. Here, we studied network activity in the dentate gyrus of NL2-deficient mice …

A conformational switch in collybistin determines the differentiation of inhibitory postsynapses

…, N Bader, D Svergun, I Tessmer, A Poulopoulos… - The EMBO …, 2014 - embopress.org
The formation of neuronal synapses and the dynamic regulation of their efficacy depend on
the assembly of the postsynaptic neurotransmitter receptor apparatus. Receptor recruitment …

Homodimerization and isoform-specific heterodimerization of neuroligins

A Poulopoulos, T Soykan, LP Tuffy… - Biochemical …, 2012 - portlandpress.com
Neuroligins are postsynaptic adhesion proteins involved in the establishment of functional
synapses in the central nervous system. In rodents, four genes give rise to neuroligins that …

[HTML][HTML] The brain's dark transcriptome: Sequencing RNA in distal compartments of neurons and glia

SA Ament, A Poulopoulos - Current opinion in neurobiology, 2023 - Elsevier
Transcriptomic approaches are powerful strategies to map the molecular diversity of cells in
the brain. Single-cell genomic atlases have now been compiled for entire mammalian brains…

[HTML][HTML] Structural connectivity of the anterior cingulate cortex, claustrum, and the anterior insula of the mouse

H Qadir, SR Krimmel, C Mu, A Poulopoulos… - Frontiers in …, 2018 - frontiersin.org
The claustrum is a narrow subcortical brain structure that resides between the striatum and
insular cortex. The function of the claustrum is not fully described, and while our previous …

Neuronal subtype-specific growth cone and soma purification from mammalian CNS via fractionation and fluorescent sorting for subcellular analyses and spatial …

…, P Veeraraghavan, A Ozkan, A Poulopoulos… - Nature protocols, 2022 - nature.com
During neuronal development, growth cones (GCs) of projection neurons navigate complex
extracellular environments to reach distant targets, thereby generating extraordinarily …

Enhancing Precision and Efficiency of Cas9-Mediated Knockin Through Combinatorial Fusions of DNA Repair Proteins

…, J Inen, B Altas, A Poulopoulos - The CRISPR …, 2023 - liebertpub.com
Cas9 targets genomic loci with high specificity. For knockin with double-strand break repair,
however, Cas9 often leads to unintended on-target knockout rather than intended edits. This …
