Research Interests

The ability to distinguish between physiological and pathogenic antigens and to make decisions about how to respond to particular pathogens or a disease condition signifies a properly functioning adaptive immune system. Dendritic cells (DCs), a diverse family of antigen-presenting cells, are required to explain how these specific responses are initiated and controlled. Our work on the immune system is focused on fundamental and translational aspects of dendritic cell biology in healthy tissue, and their aberrant functions and distribution in disease. Leveraging our broad and deep expertise in human immunology, we are addressing using human patient samples and disease models longstanding questions related to basis for the functional specialization of human DC subtypes including, the selective co-receptor and cytokine production during immune responses, T cell skewing, differentiation and involvement in disease. Our work has revealed the discovery of a new inflammatory dendritic cell type and mechanisms we have exploited to enhance immune-based treatment efficiency in cancer and autoimmunity, ultimately with the goal of harnessing these mechanisms for the development of new vaccines and immunotherapies for some of the challenging human diseases.
