Research Abstract:

Our laboratory investigates two areas of immunology, the biology of natural killer (NK) cells and immune defects in patients with autoimmunity. First, we are interested in the development of NK cell memory and the regulation of NK cell interferon-gamma (IFN-y) production. NK cells are innate immune lymphocytes capable of recognizing and killing target cells and producing immunoregulatory cytokines, especially interferon gamma IFN-y. NK cells are important for the initial control of a variety of pathogens, and defects in NK cells lead to fatal infections. One classical distinction between innate immune cells, including NK cells, and adaptive immune cells (i.e., T and B cells) is the restriction of immunologic memory to adaptive immunity. Immune memory has two primary features: (1) the ability to respond to specific antigens and (2) an amplified immune response upon subsequent antigen exposure. We have demonstrated that in contrast to our current understanding of innate immunity, NK cells exhibit properties of immunologic memory. Utilizing an adoptive transfer system, NK cells with a history of prior cytokine activation were found to maintain an NK-intrinsic enhanced capacity to produce IFN-y upon re-stimulation. This “"memory-like" property of NK cells is not antigen specific and is unique among innate immune cells.

The second focus of our laboratory is the investigation of immune defects in pediatric patients with autoimmunity. Specifically, we are utilizing whole exome sequencing to identify candidate genes and pathways that contribute to pediatric autoimmune disease.
