A primary focus of the Sebzda laboratory is discovering new ways to manipulate adaptive immune responses to improve disease outcome in humans.
The adaptive immune system (i.e. T cells, B cells, and NK cells) eliminates cancer-forming cells and invading pathogens. If this system is too aggressive, a variety of autoimmune disorders can occur, including diabetes, multiple sclerosis, colitis and Crohn’s disease, rheumatoid arthritis, and lupus. On the other hand, acquired or genetic defects that imping on immunity can be devastating, as evidenced by AIDS (acquired immune deficiency syndrome) and SCID (severe combined immune deficiency) patients. Moreover, tumors co-opt regulatory components of the immune system to avoid detection and become malignant. Therefore, a balance must be achieved to allow for pathogen and tumor clearance while remaining tolerant towards self.
A primary focus of the Sebzda laboratory is discovering new ways to manipulate adaptive immune responses to improve disease outcome in humans. To do this, we utilize a variety of mouse models to identify “bottlenecks” in the immune system that can be targeted with drugs to augment (pathogen and tumor clearance) or diminish (autoimmunity) adaptive immunity. Importantly, we have verified that these systems are shared by humans and thus are a valid therapeutic target.
