Cutaneous gene therapy. Principles and prospects

As investigators continue to close the gap between basic research and clinical science, gene therapy is becoming of increasing interest to the dermatologist. Most notably, recent advances in gene-based cancer therapy, DNA vaccination, and molecular pharmacology have opened new avenues for investigation beyond those of the traditional gene replacement applications. Different gene delivery systems are currently being tested, each with specific advantages and disadvantages. This article summarizes some of the principles of gene therapy and its applications to cutaneous diseases.
