Future of HIV treatment found in the sea?

Worldwide 36.7 million people globally are living with HIV, and of these 20.9 million people are accessing antiretroviral therapy according to recent estimates. Antiretroviral drugs are used in an attempt to control HIV infection, and there are several different ‘classes’ or kinds of them. As with a number of other prescription drugs, antiretroviral resistance is a serious problem, so discovering new ways of treating infections is essential if medicine is to stay ahead of the game.

SFU researchers from the Faculty of Health Sciences are intent on discovering new classes of drugs to help treat HIV infections. In a new study published in Antiviral Research, the research team, led by Ian Tietjen, Zabrina Brumme, and Mark Brockman, tested the antiviral activities of over 250 compounds isolated from marine invertebrates and microorganisms. The study found six new compounds with anti-HIV activity, including one called ‘bengamide A’ which was able to inhibit HIV replication at low concentrations similar to those of licensed antiretroviral drugs. Through a series of tests the research team was able to show that bengamide A acts on HIV by targeting the ‘NF-κB cell signaling pathway’, which results in a suppression of viral replication. Discovery of bengamide A, and other similar compounds will help with the design and development of future therapeutics to help combat HIV, and other viral diseases.

The study is dedicated to the memory of co-author Mark Wainberg, who was a leading Canadian HIV researcher, activist and colleague.

    SFU researcher to study role of racism on chronic disease among Indigenous people in Canada
    Indigenous people in Canada experience higher rates of chronic disease, such as heart disease, cancer and diabetes, than other Canadians – yet the role that racism plays in preventing and treating chronic disease is underexplored. Faculty of Health Sciences PhD candidate Krista Stelkia plans to change this with her research.

    Medical tourism research reveals health inequities facing local populations in Mexico
    Krystyna Adams, who convocates this month with a PhD in health sciences, spent three months living in Mexico to learn how medical tourism practices shape health-care delivery. The research, conducted for her thesis, illustrates how the medical tourism industry might exacerbate global health inequities if health-care resources are only used to provide care to those who can afford to pay.
