The Klatt Lab

With more than 30 million individuals infected with HIV worldwide, the need for more effective prevention or intervention strategies is crucial. The Klatt lab focuses on mucosal immunology as well as understanding the microbiome relative factors important in HIV infection. We utilize both human samples as well as the non-human primate model of HIV, simian immunodeficiency virus (SIV) infection of macaques, for our studies. It is our mission to keep our research fluid and ever expanding, to always be contributing to the advancements in research.
