Dr. John David Farrar's lab at UT Southwestern Medical Center studies how the body's internal clocks, known as circadian rhythms, affect immune responses, particularly in T cells responding to influenza. The lab investigates the role of specific receptors that communicate signals from the nervous system to immune cells, aiming to better understand how timing influences the effectiveness of immunity. This research could lead to advancements in vaccine design and improve our insights into how time-related factors such as jet lag affect immune function during viral infections.

Dr. Ivan D'Orso's lab focuses on understanding how the HIV-1 virus remains hidden in the body and how it can be reactivated. They explore the role of transcription factors and viral enhancers in regulating HIV-1's activation, which could lead to new treatments or cures for HIV infections. By studying cellular models and samples from infected patients, the lab aims to reveal the mechanisms that control HIV's behavior in latent states, contributing to the global effort to end the HIV epidemic.

Dr. Julie K. Pfeiffer's lab studies how intestinal microbiota affect the infection of enteric viruses, like reoviruses. The research looks at how different strains of these viruses interact with gut bacteria and how those interactions can either enhance or inhibit viral replication. This work aims to uncover the complex relationships between viruses and the gut microbiome, which could lead to new insights into combating viral infections.

Dr. Neal Mathew Alto's lab focuses on understanding how pathogenic bacteria, particularly Salmonella Typhimurium, evade the host's immune systems. They investigate the roles of specific bacterial proteins that coordinate the bacteria's division and survival within host cells. By studying these interactions, the lab aims to identify new strategies for developing drugs to combat infections caused by these bacteria.

Dr. Tuoqi Wu's lab focuses on understanding how specific immune cells, called CD8 T cells, respond to chronic viral infections like HIV, HBV, and HCV. Their research aims to enhance the immune response against these viruses by investigating different types of CD8 T cells, particularly a special group that is more effective in fighting infections. By uncovering the mechanisms that allow these cells to maintain their functionality over time, they hope to develop new strategies to improve immunotherapies for chronic infections.
