Hiding behind quite a few disguises, HIV has been evading researchers for years, leaving the seek for a vaccine as elusive because the virus itself.
As soon as believed to exist as pure strains or subtypes, new analysis reveals the virus evolves continuously, combining harmful parts that complicate remedy.
As a part of its evasive methods, the virus can lie dormant in cells, avoiding therapies and the physique’s personal immune system. In the meantime, the virus continues to precise a heavy international toll. The World Well being Group (WHO) estimates that, as of 2023, roughly 40 million folks globally live with HIV, 65% of them within the WHO’s African Area.
Schulich Medication & Dentistry researcher and bioinformatician Abayomi Olabode is utilizing knowledge science and community evaluation instruments to deal with these challenges.
“Accurately defining HIV subtypes is key to developing effective vaccines,” stated Olabode, who’s engaged on an algorithm to assist researchers higher classify the virus’s continuously altering strains.
“For years, vaccine development has been based on the idea the virus consists of pure strains. However, recent research shows that many of these strains are actually a mix of different ones. This recombination of strains can lead to new variants that become drug-resistant, making them harder to treat.”
Olabode is working alongside a number of the world’s high scientists within the fields of HIV remedy, drug resistance and precision medication at Schulich Medication & Dentistry, together with Artwork Poon, Eric Arts, Richard Gibson and Miguel E. Quiñones-Mateu.
Exploiting the social lifetime of HIV
Olabode gained worldwide recognition by his analysis revealed within the Proceedings of the Nationwide Academy of Sciences in 2022, the place he introduced machine studying methods and social networking to the research of HIV genomes.
Social networks, initially developed within the social sciences to check human connections and affect, are actually serving to researchers decode the virus’s advanced interactions—providing new hope within the battle towards HIV.
“Understanding these patterns could provide insights into designing a more effective vaccine,” stated Olabode, who combines an MSc in medical molecular biology with genetics, a grasp’s in public well being with a Ph.D. in bioinformatics.
Olabode and Arts are exploring strategies to “wake up” dormant viruses inside cells, making them susceptible to the immune system and coverings. Olabode’s algorithm compares genetic sequences from HIV-infected people with an unlimited database to pinpoint widespread epitopes—viral fragments that set off immune responses.
“Finding the most prevalent epitopes is key to developing an effective, affordable vaccine,” he stated.
Whereas customized therapies stay pricey, Olabode’s evaluation goals to determine broad options that may very well be utilized throughout various populations, finally making HIV remedy and prevention extra accessible.
“Until precision medicine becomes more affordable, we need general approaches that work for most people,” he stated. “The goal is to eventually tailor treatments by combining an individual’s genetic and immunologic information with the infecting virus’s genetic profile.”
Born in Nigeria, Olabode was launched to the world of infectious ailments at an early age by his father, a virologist and vaccinologist, who turned each an inspiration and driving power in his profession.
“My passion to study HIV came from being around a huge number of people who were suffering from the disease,” Olabode stated. “Until drugs became cheaper and available, many died.”
Drawn to the analytics facet of the analysis throughout his molecular biology program, Olabode did his Ph.D. in bioinformatics, the place he centered on drug resistance in HIV and evolution of viruses of public well being significance. Dropped at Western by Poon, who additionally mentors him, Olabode goals to contribute to analysis that advances our understanding of the virus and brings us nearer to a remedy.
“Knowing that we’re making progress toward a cure, or more effective treatments, is incredibly exciting. Every step brings us closer to improving the lives of those affected by HIV.”
