Fidgetin-like 2 (FL2) is a human enzyme that slows the rate at which skin cells migrate to wounds to heal them. If this enzyme is suppressed/absent, skin cells move faster, speeding the healing process. [1]
Delivery
Molecules of silencing RNA ( siRNA) that bind to a gene's messenger RNA (mRNA) can inhibit the production of FL2, but siRNAs require protection from degradation in order to reach a wound site. [2]
In 2015, researchers disclosed the successful use of nanoparticles to ferry siRNA molecules to their intended targets, reducing healing times in mice with skin excisions or burns. The result was normal, well-orchestrated tissue, including hair follicles and supportive collagen network. [1] [2]
