A retrovirus is a virus that uses RNA as its genetic material. When a retrovirus infects a cell, it makes a DNA copy of its genome that is inserted into the DNA of the host cell. There are a variety of different retroviruses that cause human diseases such as some forms of cancer and AIDS. Retroviral vectors are genetically engineered retroviruses. They have been used for the transfer of genes into the mammalian host cells for over 20 years. The retroviral vectors derived from the Moloney murine leukaemia virus are the most common retrovirus. They can efficiently integrate and replicate inside the genome of the host digitales.com.auted Reading Time: 4 mins. retroviral vector ret·ro·vi·ral vec·tor a specially constructed retrovirus containing one or more genes to correct certain genetic disorders.

In the future, it might be that powerful hybrid delivery systems that utilise the desirable properties of different vectors can be synthesised according to individual laboratory and clinical requirements.
