Small cyclic peptide drugs to block HIV's Nef protein and help clear hidden virus

Developing Cyclopeptide Nef Inhibitors to Facilitate HIV-1 Eradication

NIH-funded research Florida State University · NIH-11131272

Researchers are developing small cyclic peptide drugs to block HIV's Nef protein so immune cells could find and kill hidden virus in people living with HIV.

What this research studies

Many people on antiretroviral therapy still have hidden HIV that the immune system cannot find. This project focuses on a viral protein called Nef that helps infected cells hide by lowering important immune markers on the cell surface. Scientists are designing and testing cyclopeptide molecules that bind Nef and stop it from hiding infected cells, using structural studies and laboratory models to guide drug design. If promising, these compounds would move from lab tests toward studies that could involve people in the future.

Who could benefit from this research

Good fit: Ideal candidates for future clinical testing would be adults living with HIV who are on suppressive antiretroviral therapy and are interested in cure-focused treatments.

Not a fit: People without HIV and those expecting immediate personal benefit should know this is preclinical work and is unlikely to help them directly right now.

Why it matters

Potential benefit: If successful, these drugs could help the immune system reveal and destroy cells harboring hidden HIV, moving the field closer to a lasting cure.

How similar studies have performed: Targeting Nef is a promising but largely preclinical approach with some laboratory evidence that blocking Nef can restore immune killing, though no proven clinical cures exist yet.
