Insights

Two studies in Neuron identify the LRRK2 gene as a cause of familial parkinsonism. Mutations in LRRK2 are linked to alpha-synuclein and tau protein deposits in affected families.

Area of Science:

  • Neuroscience
  • Genetics

Background:

  • Familial parkinsonism is a neurodegenerative disorder with complex genetic underpinnings.
  • Previous research has explored various genetic factors contributing to Parkinson's disease.

Discussion:

  • Two recent papers pinpoint the Leucine-Rich Repeat Kinase 2 (LRRK2) gene as a causative factor in familial parkinsonism.
  • Dominantly inherited missense mutations within the LRRK2 gene are associated with a wide range of neuropathological findings.

Key Insights:

  • The identified LRRK2 mutations lead to neuropathological features characteristic of Parkinson's disease, including alpha-synuclein and tau protein aggregation.
  • The LRRK2 gene encodes a large protein with predicted functional domains including leucine-rich repeats and Ras/GTPase, tyrosine kinase-like, and WD40 domains.

Outlook:

  • Further research into LRRK2 function and its role in protein aggregation may reveal novel therapeutic targets for Parkinson's disease.
  • Understanding the specific mechanisms by which LRRK2 mutations cause parkinsonism is crucial for developing effective treatments.

Protein Kinases and Phosphatases

Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.
Protein kinases
Many proteins in the cell are regulated by phosphorylation, the addition of a phosphate group. A family of enzymes called kinases...

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

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's Disease: Treatment

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of its...

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...
