Molecular Interplay of ISG15/ISGylation in Neuropathologies

Area of Science:

• Neuroscience
• Molecular Biology
• Biochemistry

Background:

• ISG15 is a ubiquitin-like protein mediating ISGylation.
• ISGylation involves covalent attachment to target proteins via enzymatic processes.
• Emerging research links ISG15 to neuroprotection and neurodegeneration.

Purpose of the Study:

• To review the role of ISG15/ISGylation in various neuropathies.
• To explore ISG15's implications in brain tumors and neurodegenerative diseases.
• To elucidate the dual function of ISG15 in acute versus chronic neurological damage.

Main Methods:

• Literature review of existing studies on ISG15 and neuropathies.
• Analysis of research on ISGylation's impact on glioblastoma progression.
• Synthesis of findings regarding ISG15's role in Alzheimer's, Parkinson's, MS, and ALS.

Main Results:

• ISG15/ISGylation promotes the progression of brain tumors like glioblastoma.
• ISG15/ISGylation exhibits a neuroprotective effect in acute brain injury.
• ISG15/ISGylation is linked to diminished neuroprotection in chronic neurodegenerative diseases.

Conclusions:

• ISG15/ISGylation plays a significant, context-dependent role in neurological disorders.
• Understanding ISG15's dual function is crucial for developing therapeutic strategies.
• Further research is needed to fully elucidate ISG15's mechanisms in neuropathies.
