Insights

This review explores the link between endolysosomal defects and Parkinson's disease (PD). It highlights the role of Rab GTPases and their interaction with leucine-rich repeat kinase 2 (LRRK2) in PD pathogenesis.

Area of Science:

  • Neurobiology
  • Cell Biology
  • Pathology

Background:

  • Neurodegenerative disease research has advanced, identifying new pathobiology mechanisms.
  • Parkinson's disease (PD) research increasingly points to endolysosomal system defects.
  • The endolysosomal system regulates vesicle trafficking, crucial for cellular homeostasis.

Purpose of the Study:

  • To review recent findings on leucine-rich repeat kinase 2 (LRRK2) and Rab GTPases in PD.
  • To elucidate the interactions between LRRK2 and Rab GTPases.
  • To understand the contribution of these interactions to Parkinson's disease pathogenesis.

Main Methods:

  • Literature review of recent studies on LRRK2, Rab GTPases, and PD.
  • Analysis of the functional interplay between LRRK2 and various Rab GTPases.
  • Synthesis of current knowledge on endolysosomal pathway involvement in PD.

Main Results:

  • Recent studies implicate endolysosomal defects in Parkinson's disease.
  • Rab GTPases are key regulators of the endolysosomal system.
  • The interaction between LRRK2 and specific Rab GTPases is a significant area of PD research.

Conclusions:

  • Understanding LRRK2-Rab GTPase interactions is critical for PD pathobiology.
  • Defects in the endolysosomal system, modulated by LRRK2 and Rab GTPases, are central to PD.
  • Further research into these interactions may reveal novel therapeutic targets for Parkinson's disease.

Rab Proteins01:14

Rab Proteins

Rab proteins constitute the largest family of monomeric GTPases, of which 70 members are present in humans. Rab proteins and their effectors regulate consecutive stages of vesicle transport such as vesicle transport, docking, and fusion to the correct recipient membrane.
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...

Rab Cascades01:25

Rab Cascades

Rab GTPases act in a regulated cascade during membrane fusion, helping the lipid bilayers mix. The Rab family of proteins are active when bound to GTP, and inactive when bound to GDP. Hence, they act as guanine nucleotide-dependent molecular switches. Rab-GTP recognizes and binds to long or short-range tethering proteins to capture the target vesicle. These tethers coordinate with SNAREs on the vesicle and the target membrane to assemble the trans SNARE complex that locks the mixing bilayers.

Parkinson's Disease: Overview01:15

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...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:

Parkinson's Disease: Treatment01:24

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...
