[iPS cell technologies toward overcoming neurological diseases]

Area of Science:

• Neuroscience
• Stem Cell Biology
• Genetics

Background:

• Neurological diseases significantly impair quality of life, yet their mechanisms remain poorly understood due to limitations in existing disease models.
• Traditional cell lines and animal models often fail to accurately replicate complex neurological disease phenotypes, especially for multifactorial or sporadic conditions.
• Induced pluripotent stem cells (iPSCs) hold promise for overcoming these limitations by retaining patient-specific genetic information.

Approach:

• This review details iPSC technologies for generating diverse neuronal types and brain organoids.
• It summarizes current advancements in iPSC-based neurological disease research.
• The review also discusses the application of iPSCs in modeling genetic variants and single nucleotide polymorphisms (SNPs) linked to disease risk.

Key Points:

• iPSCs provide an expandable source of patient-derived neurons and glial cells for disease modeling.
• iPSC technology enables the study of genetic factors influencing neurological disease risk.
• Applications extend to drug discovery and regenerative medicine for brain disorders.

Conclusions:

• iPSC technology is transforming neurological disease research, offering unprecedented opportunities for understanding and treating brain disorders.
• Despite advancements, challenges remain in fully leveraging iPSC potential for comprehensive brain disorder research and therapeutic development.
