Keratinocyte gene transfer and gene therapy

Area of Science:

• Biotechnology
• Molecular Biology
• Dermatology

Background:

• Gene therapy aims to treat inherited and acquired diseases by delivering therapeutic genes.
• Efficient gene delivery, prolonged expression, and host safety are critical for successful gene therapy.
• Current challenges include limited cell survival, transient gene expression, and stem cell targeting difficulties.

Purpose of the Study:

• To explore the potential of epidermal and oral keratinocytes as vehicles for gene therapy.
• To identify strategies for overcoming current gene therapy limitations using keratinocytes.
• To discuss the application of keratinocyte-based gene therapy for various diseases.

Main Methods:

• Utilizing the inherent properties of keratinocytes, including stem cell presence, regulated gene expression, tissue accessibility, and secretory capacity.
• Employing ex vivo and in vivo gene transfer strategies.
• Developing keratinocyte-specific promoters for sustained transgene expression.

Main Results:

• Keratinocytes offer a promising platform for gene therapy due to their unique biological characteristics.
• Strategies are being developed for stem cell targeting, persistent gene expression, and therapeutic product secretion.
• Gene therapy in keratinocytes can facilitate local or systemic delivery of therapeutic agents.

Conclusions:

• Epidermal and oral keratinocytes present a viable strategy for advancing gene therapy applications.
• Further research and optimization of gene therapy techniques in keratinocytes hold great promise for treating a wide range of diseases.
• Gene therapy using keratinocytes offers potential for both local and systemic treatment of genetic and acquired conditions.
