Insights

Deubiquitinating enzymes (DUBs) are key regulators in multiple sclerosis (MS) pathogenesis. Targeting these enzymes shows promise for developing new MS therapies.

Area of Science:

  • Neuroimmunology
  • Molecular Biology
  • Genetics

Background:

  • Multiple sclerosis (MS) is a prevalent autoimmune disorder of the central nervous system (CNS) with complex etiology involving genetic and environmental factors.
  • Ubiquitination, regulated by deubiquitinating enzymes (DUBs), plays a critical role in immune signaling and responses.
  • Genetic studies have linked polymorphisms in DUB genes TNFAIP3 and USP18 to increased MS susceptibility.

Purpose of the Study:

  • To explore the role of DUBs in the pathogenesis of MS and its animal model, experimental autoimmune encephalomyelitis (EAE).
  • To investigate DUBs as potential therapeutic targets for MS treatment.

Main Methods:

  • Review of genetic association studies (GWAS) identifying DUB gene polymorphisms related to MS.
  • Analysis of experimental autoimmune encephalomyelitis (EAE) studies investigating DUB function in disease models.
  • Examination of DUB involvement in controlling distinct immune cell populations in EAE.

Main Results:

  • GWAS identified associations between DUB genes (TNFAIP3, USP18) and MS susceptibility.
  • EAE studies provide biological evidence for the role of these DUBs in MS-like pathology.
  • Other DUBs have been shown to influence specific cell populations in EAE.

Conclusions:

  • Deubiquitinating enzymes (DUBs) are emerging as critical regulators in MS and EAE.
  • DUBs represent promising therapeutic targets for the clinical management of multiple sclerosis.

The Proteasome01:13

The Proteasome

Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Regulated Protein Degradation02:58

Regulated Protein Degradation

It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Export of Misfolded Proteins out of the ER01:32

Export of Misfolded Proteins out of the ER

After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...
