摘要：
In one aspect, the invention provides methods and compositions for the expression of small RNA molecules within a cell using a retroviral vector (FIG. 1A). Small interfering RNA (siRNA) can be expressed using the methods of the invention within a cell. In a further aspect, the invention provides methods for producing siRNA encoding lentivirus where the siRNA activity may interfere with the lentiviral life cycle. In yet a further aspect, the invention provides methods for expression of a small RNA molecule within a cell, such as an siRNA capable of downregulating CCR5, wherein expression of the small RNA molecule is relatively non-cytotoxic to the cell. The invention also includes small RNA molecules, such as an siRNA capable of downregulating CCR5, that are relatively non-cytotoxic to cells.
