Disclosed is a method of expressing an exogenous gene in a mammalian cell, involving infecting the cell with a non-mammalian virus, such as a baculovirus, whose genome carries an exogenous gene, and growing the cell under conditions such that the gene is expressed. Exogenous genes are delivered to mammalian cells by use of a transfer vector such as that described in the figure. Also disclosed is a method of treating a gene deficiency disorder in a mammal by providing to a cell a therapeutically effective amount of a virus whose genome carries an exogenous gene and growing the cell under conditions such that the exogenous gene is expressed in the mammal.

L'invention a pour objet un procédé d'expression d'un gène exogène dans une cellule mammalienne. Le procédé consiste à infecter la cellule à l'aide d'un virus non mammalien (par exemple un baculovirus) dont le génome est porteur d'un gène exogène, et à cultiver la cellule dans des conditions permettant l'expression du gène. Les gènes exogènes sont introduits dans les cellules mammaliennes à l'aide d'un vecteur de transfert tel que celui représenté dans la figure. L'invention concerne également un procédé permettant de traiter un trouble lié à une carence génique chez un mammifère. On introduit dans une cellule une quantité thérapeutique efficace d'un virus dont le génome est porteur d'un gène exogène, et on cultive ladite cellule dans des conditions permettant l'expression du gène exogène chez un mammifère.
