Mechanical Forces Guide Axon Growth through the Nigrostriatal Pathway in an Organotypic Model

Advanced Science, EarlyView.
Nano‐pulling is a magnetic nanoparticle‐based technology for guiding and promoting the axon growth of induced pluripotent stem cell‐derived dopaminergic neurospheres in vitro or neural progenitors transplanted in the brain tissue. Fine control of axon guidance is essential for reconstructing neural networks and restoring functional connectivity in the ...

Optical dopamine monitoring with dLight1 reveals mesolimbic phenotypes in a mouse model of neurofibromatosis type 1

eLife, 2019
Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder whose neurodevelopmental symptoms include impaired executive function, attention, and spatial learning and could be due to perturbed mesolimbic dopaminergic circuitry.

Generation of Neural Organoids and Their Application in Disease Modeling and Regenerative Medicine

Advanced Science, EarlyView.
Neural organoids provide a versatile platform for neurological research. Advances in organoid technology have partially achieved human neural tissue complexity in terms of tissue structure, cell diversity, and neural signaling, offering insights into neural disorders and regenerative strategies. Technology advances from biomaterials, bio‐manufacturing,

Zeb2 is a negative regulator of midbrain dopaminergic axon growth and target innervation

Scientific Reports, 2017
Neural connectivity requires neuronal differentiation, axon growth, and precise target innervation. Midbrain dopaminergic neurons project via the nigrostriatal pathway to the striatum to regulate voluntary movement.

Analysis of pacemaker activity in a two-component model of some brainstem neurons [PDF]

arXiv, 2017
Serotonergic, noradrenergic and dopaminergic brainstem (including midbrain) neurons, often exhibit spontaneous and fairly regular spiking with frequencies of order a few Hz, though dopaminergic and noradrenergic neurons only exhibit such pacemaker-type activity in vitro or in vivo under special conditions.

Neuronal FGF13 Inhibits Mitochondria‐Derived Damage Signals to Prevent Neuroinflammation and Neurodegeneration in a Mouse Model of Parkinson's Disease

Advanced Science, EarlyView.
This study elucidates a novel role of FGF13 in manipulating neuronal fate via mitochondrial transfer. FGF13 is identified as a mitochondria‐stabilizing protein by interacting with mitochondrial proteins. Under stress, the decrease of neuronal FGF13 fails to retain mitochondria within the cytoplasm, leading to the release of damaged mitochondria to ...

The BE (2)-M17 cell line has a better dopaminergic phenotype than the traditionally used for Parkinson´s research SH-SY5Y, which is mostly serotonergic

IBRO Neuroscience Reports, 2022
SH-SY5Y is a cell line derived from human neuroblastoma. It is one of the most widely used in vitro models to study Parkinson’s disease. Surprisingly, it has been found that it does not develop a dopaminergic phenotype after differentiation, questioning ...

A neuroeconomic theory of rational addiction and nonlinear time-perception [PDF]

Neuro Endocrinol Lett. 2011;32(3):221-225, 2011
Neuroeconomic conditions for "rational addiction" (Becker and Murphy, 1988) have been unknown. This paper derived the conditions for "rational addiction" by utilizing a nonlinear time-perception theory of "hyperbolic" discounting, which is mathematically equivalent to the q-exponential intertemporal choice model based on Tsallis' statistics.

Prokineticin-2 upregulation during neuronal injury mediates a compensatory protective response against dopaminergic neuronal degeneration

Nature Communications, 2016
Prokineticin-2 (PK2), a recently discovered secreted protein, regulates important physiological functions including olfactory biogenesis and circadian rhythms in the CNS.

The Locus Coeruleus‐Periaqueductal Gray GABAergic Projection Regulates Comorbid Pain and Depression

Advanced Science, EarlyView.
LC‐GABA neurons exhibit elevated activity to noxious and aversive stimuli in chronic pain, and their activation alleviates pain‐ and depression‐like behaviors. While LC‐GABA neurons target LC‐NA neurons and GABA and Glu neurons in the vlPAG, they modulate the pain responses of LC‐NA neurons but regulate pain‐ and depression‐like behaviors through their
