Akkina Lab

Dr. Akkina is a Professor of Virology. The Akkina laboratory focuses on vaccination and antiviral therapy strategies for HIV intervention using rodent models. Ongoing studies involve developing high efficiency gene transfer methods including viral pseudotype and ribozyme expressing vectors. Dr. Akkina’s laboratory is funded by multiple NIH grants and other extramural sources and is unique in developing and utilizing SCID-hu and RAG mice as novel models in which to study HIV and Dengue virus intervention. This work has lead to new models to assess topical mucosally applied drugs to prevent sexually transmitted HIV infection.

An Ultrasensitive In Vivo Latent HIV Outgrowth Assay Using Humanized Mice

The primary aim of our studies is to exploit this unique in vivo model for serial passage of chimpanzee SIVcpz and sooty mangabey SIVsm viral strains, the progenitors of HIV-1 and HIV-2, respectively, and determine the genetic and phenotypic changes responsible for the emergence of the HIV viral strains.

research project

Modeling the Molecular Evolution of SIV to HIV using Humanized Mice

To develop a complete cure to HIV, it is important that improved and more sensitive tests are developed that can verify if a patient is fully cured and free of the virus. We will use humanized mice that are susceptible to HIV infection to develop the hmVOA test. Results of these studies are expected to be of high importance to the HIV Cure field.
