Research Abstract
Although there is intense interest in improving vaccine design and efficacy, these efforts are hampered by a lack of knowledge about how human immune responses are coordinated and developed inside lymphoid tissues. The vaccine development process is traditionally empirical, expensive, labor-intensive, and slow, making it difficult to rapidly respond to pandemics and pathogens of global concern. Though blood-based assays are becoming increasingly sophisticated, these methods often fail to identify strong correlates of protection for many of the deadliest pathogens of our time as many important cell types that are responsible for developing adaptive immunity are not found in peripheral blood. One way to circumvent this problem is to use organoid technologies that recapitulate the major features of adaptive immunity in vitro for infection and vaccine testing.

Immune organoids can be produced from human tonsil tissues, spleen, and lymph nodes. These organoids respond appropriately to influenza vaccines and viruses and recapitulate many of the key features of the adaptive response, such as differentiation of B cells into plasmablasts, T cell activation, and specific antibody secretion. The major goals of the Wagar lab are to 1) expand this vaccine work to other infectious diseases such as SARS-CoV2, 2) unravel mechanisms involved in regulating human adaptive immunity, and 3) explain inter-individual variability in vaccine responsiveness. It is our hope that engineering strategies to help us dissect the mechanistic aspects of human immunity will accelerate and inform vaccine design.
Short Biography
Lisa Wagar is an Assistant Professor in the Department of Physiology and Biophysics at the University of California, Irvine where her lab studies human vaccine responses and develops tools to investigate human adaptive immunity. Lisa is passionate about translational human immunology and collaborative efforts to improve and accelerate vaccine design for infectious diseases of global concern. UC Irvine is uniquely situated for multidisciplinary and collaborative efforts in vaccine immunology, with abundant interactions between the Department of Physiology and Biophysics, Institute for Immunology, and the Vaccine R&D Center. The mission of the Wagar lab is to accelerate vaccine design and immunotherapies to ultimately understand, treat, and prevent human disease.

Dr. Wagar received her PhD in Immunology (2013) at the University of Toronto under the mentorship of Dr. Tania Watts. During her doctoral work, Lisa completed projects related to human T cell responses against influenza and proposed vaccination strategies to promote long-term protection against influenza disease. She then went on to a postdoctoral fellowship in Dr. Mark Davis’s lab at Stanford University, where she developed immune organoid technologies for studying human adaptive immune responses to influenza vaccination and infection in vitro.
