Theoretical analysis of divalent cation effects on aptamer recognition of neurotransmitter targets
Nako Nakatsuka, Dmitry Momotenko, Annina Stuber
Aptamer-based sensing of small molecules such as dopamine and serotonin in the brain, requires characterization of the specific aptamer sequences in solutions mimicking the in vivo environment with physiological ionic concentrations. In particular, divalen ...
2023Dopamine Transporter, PhosphoSerine129 alpha-Synuclein and alpha-Synuclein Levels in Aged LRRK2 G2019S Knock-In and Knock-Out Mice
Salvatore Novello, Chiara Domenicale
The G2019S mutation in leucine rich-repeat kinase 2 (LRRK2) is a major cause of familial Parkinson's disease. We previously reported that G2019S knock-in mice manifest dopamine transporter dysfunction and phosphoSerine129 alpha-synuclein (pSer129 alpha-syn ...
MDPI2022Aptamer-modified biosensors to visualize neurotransmitter flux
Nako Nakatsuka, Emilie Vuille-Dit-Bille
Chemical biosensors with the capacity to continuously monitor various neurotransmitter dynamics can be powerful tools to understand complex signaling pathways in the brain. However, in vivo detection of neurochemicals is challenging for many reasons such a ...
2022Implantable aptamer–field-effect transistor neuroprobes for in vivo neurotransmitter monitoring
While tools for monitoring in vivo electrophysiology have been extensively developed, neurochemical recording technologies remain limited. Nevertheless, chemical communication via neurotransmitters plays central roles in brain information processing. We de ...
2021Cell-type-specific nicotinic input disinhibits mouse barrel cortex during active sensing
Carl Petersen, Sylvain Crochet, Célia Roxane Gasselin, Benoît Hohl
Fast synaptic transmission relies upon the activation of ionotropic receptors by neurotransmitter release to evoke postsynaptic potentials. Glutamate and GABA play dominant roles in driving highly dynamic activity in synaptically connected neuronal circuit ...
CELL PRESS2021Dysfunction of homeostatic control of dopamine by astrocytes in the developing prefrontal cortex leads to cognitive impairments
Graham Knott, Corrado Cali, Nicole Déglon, Tamara Zehnder, Luca Pucci, Andrea Chicca
Astrocytes orchestrate neural development by powerfully coordinating synapse formation and function and, as such, may be critically involved in the pathogenesis of neurodevelopmental abnormalities and cognitive deficits commonly observed in psychiatric dis ...
2020Glutaredoxin 1 Downregulation in the Substantia Nigra Leads to Dopaminergic Degeneration in Mice
Background Parkinson's disease (PD) is characterized by a severe loss of the dopaminergic (DA) neurons in the substantia nigra pars compacta (SNpc). Perturbation of protein thiol redox homeostasis has been shown to play a role in the dysregulation of cell ...
2020Templating colloidal sieves for tuning nanotube surface interactions and optical sensor responses
Ardemis Anoush Boghossian, Benjamin Paul Johanès Gabriel Lambert, Daniel Jerôme Siefman, Alice Judith Gillen, Shang-Jung Wu
Surfactants offer a tunable approach for modulating the exposed surface area of a nanoparticle. They further present a scalable and cost-effective means for suspending single-walled carbon nanotubes (SWCNTs), which have demonstrated practical use as fluore ...
2019Estimating the Readily-Releasable Vesicle Pool Size at Synaptic Connections in the Neocortex
Henry Markram, Eilif Benjamin Muller, Srikanth Ramaswamy, Rodrigo de Campos Perin, Natali Barros Zulaica, Giuseppe Chindemi
Previous studies based on the 'Quantal Model' for synaptic transmission suggest that neurotransmitter release is mediated by a single release site at individual synaptic contacts in the neocortex. However, recent studies seem to contradict this hypothesis ...
2019The metabolite BH4 controls T cell proliferation in autoimmunity and cancer
Genetic regulators and environmental stimuli modulate T cell activation in autoimmunity and cancer. The enzyme co-factor tetrahydrobiopterin (BH4) is involved in the production of monoamine neurotransmitters, the generation of nitric oxide, and pain(1,2). ...
