A potential step toward an HIV cure has emerged from Melbourne’s Peter Doherty Institute for Infection and
Immunity. Scientists have developed a novel method using mRNA technology to force the virus out of its hiding
places within human cells, a long-standing obstacle in HIV cure research.
This breakthrough could pave the way for complete viral clearance from the body.
The virus’s ability to conceal itself within white blood cells creates a reservoir that evades both the immune
system and drug interventions. The new approach employs mRNA, similar to that used in Moderna and
Pfizer/BioNTech COVID-19 vaccines, to make the virus visible.
Published in Nature communications, the study details how mRNA, encased in specially designed lipid
nanoparticles (LNPs), can be delivered to cells harboring HIV. The mRNA then instructs these cells to reveal
the virus. Globally,nearly 40 million people live with HIV,requiring lifelong medication to suppress the
virus. According to UNAids, one person died from HIV every minute in 2023.
Dr. Paula Cevaal,research fellow at the Doherty Institute and co-frist author,noted that delivering mRNA to
these specific white blood cells was “previously thought impractical” due to their resistance to standard LNPs.
The team’s new LNP, called LNP X, overcomes this barrier. “Our hope is that this new nanoparticle design could
be a new pathway to an HIV cure,” she said.
“We where overwhelmed by how [much of a] night and day difference it was – from not working before, and then
all of a sudden it was working. and all of us were just sitting gasping like, ‘wow’.”
According to Cevaal, initial test results were so promising they seemed unbelievable, requiring repeated
confirmation.
Further studies are needed to determine if revealing the virus is sufficient for the immune system to eliminate
it, or if combination therapies will be necessary. The current research is laboratory-based, using cells from
HIV patients. Clinical request will require extensive animal testing and human safety trials, a process
likely spanning years.
While acknowledging the challenges of translating biomedical research into clinical practice, Cevaal emphasized
the unprecedented effectiveness of this new approach in revealing the virus.Dr. michael Roche of the
University of Melbourne, co-senior author, suggested the discovery could extend beyond HIV, impacting research
into cancers and other diseases involving similar white blood cells.
Dr. Jonathan Stoye, a retrovirologist at the Francis Crick Institute, called the approach a major advance but
emphasized the need for further research on how to effectively kill the exposed virus.
What’s next
The researchers plan to conduct animal studies to assess the effectiveness of LNP X in vivo. If accomplished,
they hope to move to human trials to evaluate the safety and efficacy of this new approach in HIV treatment.
