Research Description

A new form of adjuvant, nanoemulsion (NE), is an oil-in-water emulsion prepared by high-speed homogenization of surfactants and solvents with an average droplet size of 200-600nm in diameter. In various animal models of disease, including hepatitis B, influenza, and RSV), it has been observed that intranasal administration of NE with antigen augmented humoral and cellular immune responsesconferring protection and attenuating disease. This makes NE a novel vaccine adjuvant that could potentiate adaptive immune responses for human vaccines. Broadly speaking, we hypothesize that NE induces cellular immunity by promoting cytokine expression, antigen presentation, and migration of APCs to draining lymph nodes to induce T cell proliferation and differentiation. However, the molecular and cellular targets of NE have yet to be fully understood. My studies aim to identify the innate pathways through which NE acts and compare these activities with those from other defined adjuvants to develop an understanding for how these adjuvants differ.
