Action potential solitons and waves in axons [PDF]

arXiv, 2022
We show that the action potential signals generated inside axons are reaction-diffusion solitons or reaction-diffusion waves, refuting the Hodgkin and Huxley hypothesis that action potentials propagate along axons with an elastic wave mechanism. Reaction-diffusion action potential wavefronts and solitons annihilate at collision and boundaries of axons,

Phase 1, First‐In‐Human, Single‐/Multiple‐Ascending Dose Study of Iluzanebart in Healthy Volunteers

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of iluzanebart, a fully human monoclonal antibody TREM2 (triggering receptor expressed on myeloid cells 2) agonist, after single‐ (SAD) and multiple‐ascending‐dose (MAD) administration.

Epitope Mapping of Anti‐Neurofascin 155 Antibody in a Large Cohort of Autoimmune Nodopathy Patients

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Autoimmune nodopathy (AN), a newly recognized disease entity, is an immune‐mediated polyneuropathy involving autoantibodies against cell adhesion molecules located in nodes of Ranvier and paranodal regions, such as neurofascin 186 (NF186) and neurofascin 155 (NF155). The present study aimed to identify the epitopes for autoantibodies

The axonal transport of mitochondria [PDF]

Journal of Cell Science, 2005
Organelle transport is vital for the development and maintenance of axons, in which the distances between sites of organelle biogenesis, function, and recycling or degradation can be vast. Movement of mitochondria in axons can serve as a general model for how all organelles move: mitochondria are easy to identify, they move along both microtubule and ...

Branching Law for Axons [PDF]

arXiv, 2003
What determines the caliber of axonal branches? We pursue the hypothesis that the axonal caliber has evolved to minimize signal propagation delays, while keeping arbor volume to a minimum. We show that for a general cost function the optimal diameters of mother ($d_0$) and daughter ($d_1$, $d_2$) branches at a bifurcation obey a branching law: $d_{0}^{\

A Stochastic Multiscale Model that Explains the Segregation of Axonal Microtubules and Neurofilaments in Neurological Diseases [PDF]

, 2015
The organization of the axonal cytoskeleton is a key determinant of the normal function of an axon, which is a long thin projection away from a neuron. Under normal conditions two axonal cytoskeletal polymers microtubules and neurofilaments align longitudinally in axons and are interspersed in axonal cross-sections.

Reconstitution of CXCR3+ CCR6+ Th17.1‐Like T Cells in Response to Ofatumumab Therapy in Patients With Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Ofatumumab, a fully human anti‐CD20 monoclonal antibody, is effective in reducing relapses and disability progression in patients with multiple sclerosis. This study aimed to examine immune profile changes associated with ofatumumab in a prospective cohort of Chinese patients with relapsing–remitting multiple ...

Fluorescent identification of axons, dendrites and soma of neuronal retinal ganglion cells with a genetic marker as a tool for facilitating the study of neurodegeneration

FASEB BioAdvances
This study characterizes a fluorescent Slc17a6‐tdTomato neuronal reporter mouse line with strong labeling of axons throughout the optic nerve, of retinal ganglion cell (RGC) soma in the ganglion cell layer (GCL), and of RGC dendrites in the inner ...

Axial and radial axonal diffusivities from single encoding strongly diffusion-weighted MRI [PDF]

arXiv, 2022
We enable the estimation of the per-axon axial diffusivity from single encoding, strongly diffusion-weighted, pulsed gradient spin echo data. Additionally, we improve the estimation of the per-axon radial diffusivity compared to estimates based on spherical averaging.

CSF Tau Is a Biomarker of Hippocampal Injury in Cryptogenic New‐Onset Refractory Status Epilepticus

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cryptogenic new‐onset refractory status epilepticus (cNORSE) is a devastating condition characterized by the de novo onset of status epilepticus with unclear etiology. The identification of relevant early biomarkers in cNORSE is important to elucidate pathophysiology, aid clinical decision‐making, and prognosticate outcomes in cNORSE.
