Researchers develop a minimally invasive biodegradable microneedle patch as a novel delivery mode for gene therapy applications
(LOS ANGELES) - There is great potential in gene therapy for treating certain types of cancer and genetic defects, immunological diseases, wounds and infections. The therapies work by delivering genes into the patients' cells, which then produce therapeutic proteins to treat the affliction.
When determining the method of delivery for these genes, there are advantages to choosing a local, rather than systemic delivery of the genetic material. With systemic delivery, there is the possibility of unwanted tissue accumulation or of the genetic material becoming unstable. It is also advantageous to target the skin as a site for local delivery, as it is easily accessible and contains fluid and lymph vessels, as well as immune cells upon which the genetic material can act to initiate treatment.
