Researchers at The University of Texas Rio Grande Valley’s Department of Health and Biomedical Sciences are working to develop a next generation of anti-HIV drugs that are more effective and have fewer side effects

To further support the study of human immunodeficiency virus 1 (HIV-1)—still one of the leading causes of death worldwide, predominantly in developing countries – the National Institutes of Health (NIH) recently awarded a grant to the UTRGV researchers for their project, called “Nano diamond Based Anti-HIV Drug Delivery Targeted Towards the Brain.”

The grant is for $432,729, starting July 1, 2018 and ending June 30, 2021. The principal investigator is Dr. Upal Roy, assistant professor at the UTRGV Department of Health and Biomedical Science. Collaborators are Dr. Shizue Mito, assistant professor in the UTRGV Department Chemistry, and Dr. Vadym Drozd, assistant professor in the Department of Mechanical and Materials Engineering at Florida International University.

The proposed research develops a molecule that will be conjugated with the microglia-specific antibody for targeted drug delivery to the brain. Microglia is a type of cell that is majorly found throughout the brain. The proposed nanodrug can be used to directly deliver an anti-HIV drug specifically to the inflammatory areas of the brain where most of the infected microglia and the virus are present.

Roy and his colleagues hypothesize that the nanodiamond-mediated drug delivery will be more efficient, safe and effective than conventional drugs.

“The patients will find these next-generation drugs less expensive, and with the simplified dosing schedule, they will stay in the treatment for a much longer period of time – which eventually will improve the quality of their lives,” he said.

The proposed research will help to stimulate the research environment at UTRGV, Roy said, and will expose current undergraduate and graduate students to the biomedical research environment.  READ MORE
