Abstract

A vector capable of transducing non-dividing and/or slowly dividing cells is provided, wherein the vector is a lentiviral LTR-deleted vector. Also provided is a method for producing a protein of interest in a non-dividing or slowly dividing cell by transducing the cell with a lentiviral LTR-deleted vector and expressing the protein of interest in the cell. In addition, target cells containing the lentiviral LTR-deleted vector are provided.

Claims

1. A lentiviral vector capable of transducing a non-dividing or slowly-dividing cell, said vector comprising a lentiviral LTR-deleted vector.

2. The vector according to claim 1, further comprising a nucleotide sequence encoding a protein of interest.

3. A method for producing a protein of interest in a non-dividing or slowly-dividing cell, comprising the steps of:

a) transducing the cell with the vector according to claim 2;

and

b) expressing the protein of interest in the cell.

4. The method according to claim 3, wherein the non-dividing cell is a neuron.

5. A target cell in vitro comprising the vector of claim 1.

6. A target cell in vitro comprising the vector of claim 2.

7. A method of performing gene delivery on a target cell comprising the steps of:

a) transducing the target cell with the vector according to claim 2;

and

b) delivering the nucleotide sequence to the target cell.
