Insights

Huntington's disease (HD) is an inherited neurodegenerative disorder caused by a toxic expansion of polyglutamine in the huntingtin protein. Strategies to reduce protein misfolding and improve clearance slow disease progression in HD models.

Area of Science:

  • Neurodegenerative diseases
  • Genetics
  • Protein conformational diseases

Background:

  • Huntington's disease (HD) is a common inherited neurodegenerative disorder.
  • It is characterized by motor, cognitive, and emotional deficits.
  • A mutation causing polyglutamine (polyQ) expansion in the huntingtin (Htt) protein is responsible for HD, leading to toxic functions and neurodegeneration.

Purpose of the Study:

  • To explore Huntington's disease (HD).
  • To present evidence supporting HD as a conformational disease.

Main Methods:

  • Review of existing literature on Huntington's disease.
  • Analysis of the role of protein misfolding and aggregation in HD pathogenesis.

Main Results:

  • The polyglutamine expansion in huntingtin protein leads to aggregation and accumulation.
  • Mitigating protein misfolding and enhancing clearance of misfolded proteins show promise in slowing HD progression in models.

Conclusions:

  • Huntington's disease is fundamentally a conformational disease.
  • Targeting protein misfolding and aggregation pathways offers therapeutic potential for HD.

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,...

Parkinson's Disease: Overview

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is to...

Parkinson Disease l: Introduction

Parkinson’s disease is a chronic, progressive neurodegenerative disorder that primarily affects movement. It is characterized by motor symptoms such as resting tremors, muscle rigidity, bradykinesia (slowness of movement), and postural instability. Patients may notice hand tremors at rest, stiffness during movement, or a shuffling gait. In addition to motor features, non-motor symptoms include sleep disturbances, mood and behavioral changes, constipation, and cognitive impairment, all of which...

Parkinson Disease ll: Pathophysiology

Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
Alzheimer Disease l: Introduction01:29

Alzheimer Disease l: Introduction

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

Disorders of the Nervous Tissue

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...
