Abstract

Insights

Genetic discoveries have identified over 10 genes causing axonal Charcot-Marie-Tooth disease (CMT), offering insights into neuronal degeneration mechanisms and potential therapies for this inherited neuropathy.

Area of Science:

  • Genetics
  • Neuroscience
  • Molecular Biology

Background:

  • Charcot-Marie-Tooth disease (CMT) encompasses a group of inherited peripheral neuropathies.
  • Axonal forms of CMT are characterized by degeneration of the longest axons in the peripheral nervous system.

Purpose of the Study:

  • To identify the genetic underpinnings of dominantly and recessively inherited axonal Charcot-Marie-Tooth disease.
  • To review the biological mechanisms contributing to these neurological disorders.

Main Methods:

  • Review of genetic studies identifying causative genes for axonal CMT.
  • Analysis of protein expression patterns and functional roles of identified genes.
  • Examination of established cellular and animal models for studying disease mechanisms.

Main Results:

  • Over 10 genes responsible for axonal CMT have been discovered in the last decade.
  • Many identified genes encode ubiquitously expressed proteins, suggesting widespread cellular roles.
  • Clinical phenotypes are being characterized, and relevant disease models are under development.

Conclusions:

  • New genetic findings illuminate neuronal degeneration pathways relevant beyond axonal CMT.
  • Understanding genetic causes aids patients, families, and scientific research.
  • Insights pave the way for therapeutic strategies for axonal CMT and related motor neuron disorders.

Cross-bridge Cycle01:26

Cross-bridge Cycle

As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

Myasthenia Gravis ll: Pathophysiology

The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...
Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...

Multiple Sclerosis l: Introduction

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
Chemical Synapses01:26

Chemical Synapses

Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
