[HTML][HTML] A time course analysis of the electrophysiological properties of neurons differentiated from human induced pluripotent stem cells (iPSCs)

…, MW Nestor, AA Sproul, S Jacob, P Koppensteiner… - PloS one, 2014 - journals.plos.org
Many protocols have been designed to differentiate human embryonic stem cells (ESCs)
and human induced pluripotent stem cells (iPSCs) into neurons. Despite the relevance of …

GABAB receptors induce phasic release from medial habenula terminals through activity-dependent recruitment of release-ready vesicles

P Koppensteiner, P Bhandari, C Önal… - Proceedings of the …, 2024 - National Acad Sciences
GABA B receptor (GBR) activation inhibits neurotransmitter release in axon terminals in the
brain, except in medial habenula (MHb) terminals, which show robust potentiation. However, …

[PDF][PDF] Ventro-dorsal hippocampal pathway gates novelty-induced contextual memory formation

F Fredes, MA Silva, P Koppensteiner, K Kobayashi… - Current Biology, 2021 - cell.com
Novelty facilitates memory formation and is detected by both the dorsal and ventral hippocampus.
Although dentate granule cells (GCs) in the dorsal hippocampus are known to mediate …

[HTML][HTML] Time-dependent reversal of synaptic plasticity induced by physiological concentrations of oligomeric Aβ42: an early index of Alzheimer's disease

P Koppensteiner, F Trinchese, M Fŕ, D Puzzo… - Scientific reports, 2016 - nature.com
The oligomeric amyloid-β (Aβ) peptide is thought to contribute to the subtle amnesic changes
in Alzheimer’s disease (AD) by causing synaptic dysfunction. Here, we examined the time …

[PDF][PDF] Multipotent progenitors instruct ontogeny of the superior colliculus

G Cheung, FM Pauler, P Koppensteiner, T Krausgruber… - Neuron, 2024 - cell.com
The superior colliculus (SC) in the mammalian midbrain is essential for multisensory
integration and is composed of a rich diversity of excitatory and inhibitory neurons and glia. …

[HTML][HTML] RIM-Binding Protein 2 organizes Ca2+ channel topography and regulates release probability and vesicle replenishment at a fast central synapse

…, T Alvanos, A Hintze, P Koppensteiner… - Journal of …, 2021 - Soc Neuroscience
Rab-interacting molecule (RIM)-binding protein 2 (BP2) is a multidomain protein of the
presynaptic active zone (AZ). By binding to RIM, bassoon (Bsn), and voltage-gated Ca 2+ …

[HTML][HTML] Modulation of fear memory by dietary polyunsaturated fatty acids via cannabinoid receptors

D Yamada, J Takeo, P Koppensteiner… - …, 2014 - nature.com

benefits of n-3 long-chain polyunsaturated fatty acid (PUFA) for patients with anxiety disorders. …

Diminished fear extinction in adolescents is associated with an altered somatostatin interneuron–mediated inhibition in the infralimbic cortex

P Koppensteiner, R Von Itter, R Melani, C Galvin… - Biological …, 2019 - Elsevier
Background Rodents and humans show an attenuation of fear extinction during adolescence,
which coincides with the onset of several psychiatric disorders. Although the ethological …

GABAB receptor auxiliary subunits modulate Cav2.3-mediated release from medial habenula terminals

…, A Kulik, B Bettler, R Shigemoto, P Koppensteiner - Elife, 2021 - elifesciences.org
The synaptic connection from medial habenula (MHb) to interpeduncular nucleus (IPN) is
critical for emotion-related behaviors and uniquely expresses R-type Ca 2+ channels (Cav2.3) …

[PDF][PDF] A cooperative mechanism involving Ca2+-permeable AMPA receptors and retrograde activation of GABAB receptors in interpeduncular nucleus plasticity

P Koppensteiner, R Melani, I Ninan - Cell reports, 2017 - cell.com
The medial habenula-interpeduncular nucleus (MHb-IPN) pathway, which connects the
limbic forebrain to the midbrain, has recently been implicated in aversive behaviors. The MHb-…
