Broadly neutralizing antibodies (bNAbs) target conserved HIV envelope regions to neutralize diverse strains, eliminate infected cells and reduce viral reservoirs, complementing antiretroviral therapy and supporting prevention and functional cure strategies.
The use of DNA scaffolds could mark a turning point in HIV vaccine design. Scientists at Scripps Research and the Massachusetts Institute of Technology (MIT) have created a new vaccine platform based on DNA origami, a material that the immune system does not recognize as a threat, avoiding unwanted responses.
In vaccine development, one might think that targeting multiple epitopes increases the likelihood of improving outcomes. However, when several immunogens are administered together, the immune system does not always generate antibodies against all of them. Two parallel studies have overcome this challenge by using multiple simultaneous immunogens against HIV, effectively triggering various types of broadly neutralizing antibody (bnAb) precursors in two different preclinical animal models.
Taimed Biologics Inc.’s TMB-365/TMB-380 long-acting combination of broadly neutralizing antibodies regimen for HIV maintenance could reshape HIV treatment management, offering a viable alternative to daily combination antiretroviral therapy (cART), the Taipei-based company said after reporting on phase IIa results.

At the 2025 meeting of the Conference on Retroviruses and Opportunistic Infections (CROI) it was the best of times, it was the worst of times. On the first full day of the conference, reports from the first HIV cure trial conducted in Africa, the RIO trial and others showed that perhaps, a broadly useful cure is on the horizon.

Scientists at the University of Pittsburgh have tested a broadly neutralizing antibody that binds the stem of a protein against H5N1 avian influenza, which prevented severe disease in nonhuman primates and was effective for at least 8 weeks. The scientists remark on the potential of the design developed by Astrazeneca plc against a possible outbreak of the influenza A virus.
The 2024 meeting of the International AIDS Society (IAS), which is being held in Munich this week, began with the announcement of another curative bone marrow transplant. The new case brings the total number of patients cured of HIV via a bone marrow transplant up to 7 since “Berlin patient” Timothy Ray Brown became the first such person in 2007.
In a paper published in the May 17, 2024, online issue of Cell, investigators from the Duke Human Vaccine Institute reported that a sequence of three immunizations in the HVTN-133 trial was sufficient for the development of heterologous or broadly neutralizing antibodies that protected against several strains of HIV.
