Summary
Biologically Engineered Vectors (BEVs) offer a novel platform for topical messenger RNA (mRNA) delivery to skin. These engineered particles effectively deliver mRNA for transient protein expression and enhance skin regeneration, outperforming lipid nanoparticles.
Area of Science:
- Biotechnology
- Regenerative Medicine
- Dermatology
Background:
- Messenger RNA (mRNA) therapeutics provide transient protein expression without genomic alteration, ideal for regenerative medicine.
- Efficient and safe delivery of mRNA to skin is a significant hurdle.
- Lipid nanoparticles (LNPs) face limitations in skin delivery due to accessibility, formulation, and local tissue responses.
Purpose of the Study:
- To develop and characterize Biologically Engineered Vectors (BEVs) as a novel platform for topical mRNA delivery.
- To evaluate the efficacy of RNA-BEVs for mRNA delivery to skin cells and assess their impact on skin regeneration.
Main Methods:
- Defined Biologically Engineered Vectors (BEVs) as biologically assembled particles for nucleic acid transport.
- Developed RNA-BEVs for topical mRNA delivery.
- Tested RNA-BEVs in reconstructed epidermis and a diabetic rat wound model.
Main Results:
- RNA-BEVs efficiently delivered functional mRNA to keratinocytes.
- Topical administration of RNA-BEVs induced transient protein expression in reconstructed epidermis.
- RNA-BEVs improved the histological quality of skin repair compared to mRNA-loaded LNPs in a diabetic rat wound model.
Conclusions:
- RNA-BEVs represent a promising biologically assembled platform for localized, transient RNA delivery.
- This platform facilitates skin regeneration through topical mRNA application.
- RNA-BEVs overcome some limitations of traditional LNP delivery systems in skin.

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
01:19Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
00:59Gene Therapy
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be inserted. The...
