Area of Science:

  • Gene therapy
  • Virology
  • Dermatology

Background:

  • Lentiviral vectors pseudotyped with viral envelope glycoproteins can modify tropism for gene delivery.
  • Targeting human skin with gene therapy holds potential for treating genetic anomalies.

Purpose of the Study:

  • To evaluate the efficiency of different pseudotyped human immunodeficiency virus (HIV)-based vectors for gene transfer in human skin xenografts.
  • To identify the most effective viral glycoprotein for cutaneous gene delivery.

Main Methods:

  • Pseudotyping HIV vectors with envelope glycoproteins from vesicular stomatitis virus (VSV-G), Zaire Ebola (EboZ) virus, murine leukemia virus (MuLV), lymphocytic choriomeningitis virus (LCMV), Rabies, or Mokola virus.
  • Qualitative and quantitative assessment of transgene expression (LacZ reporter gene) in human skin xenografts.
  • Double-labeling immunofluorescence for beta-galactosidase, involucrin, and integrin beta1.
  • TaqMan PCR to determine genome copy number.

Main Results:

  • High transgene expression was observed in dermal fibroblasts transduced with VSV-G, EboZ, or MuLV pseudotyped vectors.
  • VSV-G, EboZ, and MuLV pseudotyped vectors effectively targeted quiescent epidermal stem cells, leading to transgene expression in differentiated progeny.
  • VSV-G pseudotyped vector demonstrated the highest efficiency for cutaneous transduction, indicated by superior beta-galactosidase expression and genome copy number.

Conclusions:

  • Pseudotyping lentiviral vectors with specific viral glycoproteins can achieve efficient gene transfer into human skin.
  • VSV-G is the most potent viral glycoprotein for pseudotyping HIV-based vectors for effective gene delivery to epidermal stem cells in the skin.
