Insights

Leucine-rich repeat kinase 2 (LRRK2) may control diverse functions by forming different protein complexes. This review explores LRRK2’s role in macroautophagy and the endolysosomal system, particularly in Parkinson's disease.

Area of Science:

  • Cell Biology
  • Neuroscience
  • Biochemistry

Background:

  • Leucine-rich repeat kinase 2 (LRRK2) is implicated in various cellular functions.
  • LRRK2 interacts with a diverse range of proteins.
  • Dysregulation of LRRK2 is linked to neurodegenerative diseases, notably Parkinson's disease.

Purpose of the Study:

  • To explore the hypothesis that LRRK2's function is context-dependent, varying with protein complex formation.
  • To focus on the role of LRRK2 in macroautophagy within the endolysosomal system.
  • To review the association between LRRK2, autophagy, and the endolysosomal pathway in the context of Parkinson's disease.

Main Methods:

  • Literature review and synthesis.
  • Analysis of existing research on LRRK2 interactors and functions.
  • Evaluation of the relevance of autophagy in Parkinson's disease genetics.

Main Results:

  • LRRK2's ability to form distinct protein complexes suggests context-specific functional regulation.
  • Evidence supports a significant association between LRRK2 and macroautophagy.
  • LRRK2 plays a role in the endolysosomal pathway, which is relevant to Parkinson's disease.

Conclusions:

  • LRRK2's diverse functions are likely mediated by its dynamic interactions and complex formation.
  • LRRK2 is a key player in the interplay between macroautophagy, the endolysosomal system, and Parkinson's disease pathogenesis.

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,...

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...

Delivery Pathways to the Lysosome01:36

Delivery Pathways to the Lysosome

Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

Autophagy01:27

Autophagy

Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

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...
