Tallie Kuang

Xiaomei (Tallie) Kuang, a Masters student from Simon Fraser University, is exploring how to eliminate a “sleeping virus”. In a person living with HIV, highly active anti-retroviral therapy (HAART) is able to keep the level of virus in the body to a minimum. However, complete removal of HIV has not been possible because of latent reservoirs that cannot be targeted with HAART. A source of virus always remains in the body that can reestablish infection if treatment is stopped. A new avenue of research is investigating how to awaken these latent cells intentionally using anti-latency agents. This would make the cells more prone to the immune system and to other therapeutic agents.

But there are hurdles in this line of treatment. “Right now, a major challenge is that these cells are hard to reactivate, and even after they are activated, the cytotoxic T-lymphocytes (CTLs) of the immune system might not be able to recognize or kill them,” explains Tallie. “One explanation for this is that these cells may not be efficient at presenting viral epitopes (viral proteins) on their surface, so CTLs don’t see them as being infected. It is also possible that anti-latency agents themselves alter epitope presentation.”

Currently, Tallie is developing an assay that will allow her to test these two theories. She will then measure the ability of reactivated cells to present HIV epitopes and determine whether exposure to anti-latency agents alters epitope presentation. With support from the CAHR Master’s Award, Tallie is able to purchase lab supplies to study HIV epitope presentation in response to different anti-latency drugs and travel to conferences to share her work with the HIV research community. Ultimately, she hopes that the results of her work can help to guide research towards the most effective anti-latency therapeutics, bringing us one step closer to a cure.

The Canadian Association for HIV Research is proud to support students like Tallie Kuang in their research through graduate research awards. Please visit https://www.cahr-acrv.ca/funding-opportunities/ to learn more.

About CAHR

With a membership of more than 1,000 researchers and others interested in HIV research, the Canadian Association for HIV Research (CAHR) is the leading organization of HIV/AIDS researchers in Canada. CAHR is the organizing body for the Annual Canadian Conference on HIV/AIDS Research (CAHR Conference).

CAHR encourages Canadian researchers to be leaders in knowledge translation and to effectively respond both to the Canadian and global HIV/AIDS epidemics. Since its founding in 1991, CAHR has promoted excellence in HIV research, including mentorship and career development of investigators entering the field.

CAHR fosters collaboration and co-operation among HIV research communities, including basic, clinical and social sciences, epidemiology and public health. CAHR also engages people living with HIV/AIDS and AIDS service organizations in ongoing dialogue and information exchange to ensure that HIV/AIDS research remains responsive to the epidemic and its stakeholders.

CAHR is a registered charity.
