Somatic cell reprogramming for Parkinson's disease treatment

open access: yesIbrain, Volume 11, Issue 1, Page 59-73, Spring 2025.
The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option

Beyond “you are what you eat”: Unlocking gut microbiota‐mediated biotransformation of dietary phytochemicals

open access: yesiMetaOmics, EarlyView.
The “efficacy paradox” of phytochemicals, low bioavailability yet significant health benefits, is associated with gut microbiota, which biotransforms dietary precursors into bioactive metabolites, enabling systemic effects. Thus, health outcomes of diet depend not just on intake “the rainbow”, but on gut microbial metabolism, redefining “you are what ...

3,4-Dihydroxyphenylalanine Reverses the Motor Deficits in Pitx3-Deficient Aphakia Mice: Behavioral Characterization of a Novel Genetic Model of Parkinson's Disease

open access: yesJournal of Neuroscience, 2005
Parkinson's disease (PD) is a neurodegenerative disease characterized by a loss of dopaminergic neurons in the substantia nigra. There is a need for genetic animal models of PD for screening and in vivo testing of novel restorative therapeutic agents ...

White Matter Dysfunction and Neurotransmitter Basis Underlying the Freezing of Gait in Parkinson's Disease

open access: yesiNew Medicine, EarlyView.
In the freezing of gait in Parkinson's disease, white matter shows decreased local activity but increased functional connectivity. These distinct dysfunctions are uniquely associated with specific neurotransmitter systems (GABA, dopamine, etc.), mapping a new neurochemical basis for this debilitating symptom. ABSTRACT Freezing of gait (FOG) is a severe

Deep Brain Stimulation of Caudal Zona Incerta for Parkinson's Disease: One‐Year Follow‐Up and Electric Field Simulations

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objective To evaluate the effects of bilateral caudal zona incerta (cZi) deep brain stimulation (DBS) for Parkinson's disease (PD) one year after surgery and to create anatomical improvement maps based on patient‐specific simulation of the electric field.

Insights on cytotoxic cells of the colonial ascidian Botryllus schlosseri [PDF]

open access: yes, 2015
Morula cells (MCs) represent the most abundant circulating hemocyte of the compound ascidian Botryllus schlosseri. They are cytotoxic cells involved in the rejection reaction between contacting, genetically incompatible colonies.

Hypervision Proton Surgery: The Future Direction of Proton Therapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Local Field Potential‐Based Programming: A Proof‐of‐Concept Pilot Study

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Programming deep brain stimulation (DBS) is still based on a trial‐and‐error approach, often becoming a time‐consuming process for both treating physicians and patients. Several strategies have been proposed to streamline DBS programming, most of which are preliminary and mainly address Parkinson's disease, a condition readily ...
