Prevention, Treatment and Control of HIV Infection

Novel methods are under investigation:

Soluble form of CD4 has been made by recombinant DNA techniques and is being studied as a viral blocking agent. As CD4 is the HIV receptor on cells, soluble CD4 may inhibit HIV from infecting cells; may block gp120-mediated events, such as cell fusions and may serve as a targeting signal to direct cytotoxic agents to HIV-infected cells.

Gene therapy approach are being developed that are designed to achieve "intracellular immunization," ie., genetically alter target cells to make them resistant to HIV.
