Targeting CD4-positive cells for anti-HIV gene therapy

Treatment of HIV early following infection is thought to be important for maximising the quality of life of patients. Conventional therapy has had some success in early intervention but resistance invariably develops. This application proposes to develop a gene therapy approach to elimiate HIV infected cells by introducing a suicide gene into those cells that harbor the virus. The advantage of this approach is the limited toxicity that is associated with gene therapies as well as the ability to target specific cell-types. It is proposed to genetically modify a strain of adenovirus to introduce a gene that will kill cells that it infects that also contain HIV. This is a novel approach and potentially may be an important treatment in the future. Anti-HIV gene therapy may also be useful in addition to the more conventional treatments.
