Delivery of gene products by intestinal cell expression

   
   

Intestinal epithelial cells of a mammalian subject are genetically altered to operatively incorporate a gene which expresses a protein which has a desired effect. The method of the invention comprises administration of a formulation containing DNA to the gastrointestinal tract, preferably by an oral route. The expressed recombinant protein is secreted directly into the bloodstream. Of particular interest is the use of the method of the invention to provide for short term delivery of gene products to the bloodstream.

Las células epiteliales intestinales de un tema mamífero genético se alteran para incorporar operativo un gene que exprese una proteína que tenga un efecto deseado. El método de la invención abarca la administración de una formulación que contiene la DNA al aparato gastrointestinal, preferiblemente por una ruta oral. La proteína recombinant expresada se secreta directamente en la circulación sanguínea. De interés particular está el uso del método de la invención de prever la entrega a corto plazo de los productos del gene a la circulación sanguínea.
