Lentiviral LTR-deleted vector
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.
1. A lentiviral vector particle capable of transducing a non-dividing or slowly-dividing cell, said vector particle comprising a lentiviral LTR-deleted (LCD) vector, wherein the LLD vector comprises sequences sufficient for reverse transcription and integration, and wherein, upon transduction, the LLD vector comprises a non-functional lentiviral 5′ LTR promoter.
2. The vector particle according to claim 1 , further comprising a nucleotide sequence of interest (NOI).
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 particle according to claim 2 , wherein the NOI encodes a protein of interest; 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 particle of claim 1 .
6. A target cell in vitro comprising the vector particle of claim 2 .
