Noninvasive approach for enhancing small interfering RNA delivery percutaneously

Area of Science:

• Dermatology
• Gene Therapy
• Nanomedicine

Background:

• Topical small interfering RNA (siRNA) shows promise for treating skin disorders.
• Noninvasive strategies offer safe and effective methods for enhancing siRNA skin permeation.
• Advantages include improved storage stability, targeted delivery, enhanced permeability, and bioavailability.

Purpose of the Study:

• To review recent advancements in noninvasive approaches for enhancing topical siRNA absorption.
• To systematically introduce concepts and mechanisms of these enhancement techniques.
• To highlight their potential for increasing cutaneous gene delivery.

Main Methods:

• Review of noninvasive techniques for siRNA absorption enhancement.
• Discussion of nanomedicine, penetration enhancers, matrix-based delivery, microneedles, iontophoresis, electroporation, and lasers.
• Analysis of enhancement mechanisms and applications in treating skin conditions.

Main Results:

• Noninvasive methods significantly enhance siRNA permeation for diverse skin applications.
• Techniques discussed are applicable to treating skin cancers, gene-related diseases, immune disorders, and wounds.
• These approaches offer potential for improved topical siRNA therapy.

Conclusions:

• Noninvasive techniques present a novel and effective treatment modality for topical siRNA application.
• Further clinical studies in humans are necessary to validate findings from animal research.
• Potential adverse effects and skin irritation associated with these methods require careful consideration.
