Abstract:
Multiple sclerosis (MS) is the most common autoimmune disease of the CNS. The etiology of MS is still unclear but it is widely recognized that both genetic and environmental factors contribute to its pathogenesis. Immune signaling and responses are critically regulated by ubiquitination, a posttranslational modification that is promoted by ubiquitinating enzymes and inhibited by deubiquitinating enzymes (DUBs). Genome-wide association studies (GWASs) identified that polymorphisms in or in the vicinity of two human DUB genes TNFAIP3 and USP18 were associated with MS susceptibility. Studies with experimental autoimmune encephalomyelitis (EAE), an animal model of MS, have provided biological rationale for the correlation between these DUBs and MS. Additional studies have shown that other DUBs are also involved in EAE by controlling distinct cell populations. Therefore, DUBs are emerging as crucial regulators of MS/EAE and might become potential therapeutic targets for the clinical treatment of MS.
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.
