Research Biography

The long-term goals of my laboratory are to identify and exploit mechanisms of cell-cell recognition and adhesion for the development of new approaches for the prophylaxis and treatment of infectious disease as well as cancer cell metastasis. Our studies on infectious disease are focused on understanding the initial recognition, adhesion, and entry events that occur between the microbial agent and host cell during the earliest stages of host cell-pathogen interaction. We have developed in vitro assays for quantification of physiologically-relevant microbial adhesion as well as in vivo intestinal xenograft systems for testing the therapeutic efficacy of identified receptors or receptor analogues. Using this approach we identified a intestinal ganglioside receptor for porcine rotavirus and synthesized a neoglycolipid receptor mimetic that can function as a nutriceutical capable of blocking both virus binding and infectivity of host cells in vitro and virus shedding and diarrhea in vivo. We  also are involved in collaborative basic and translational research studies aimed at identifying and delivering naturally occurring or synthetic inhibitors of apicomplexan parasites, particularly Cryptosporidium, in efforts to provide new approaches for the treatment of enteric parasitic disease in animals and people that are not readily amenable to traditional vaccine approaches. Our studies on cancer cell metastasis are aimed at understanding the mechanism by which the mechanical microenviroment of the primary tumor regulates cancer cell-cell adhesion and metastasis. Cancer deaths are primarily caused by metastasis, not the primary tumor. Cancer cells sense, process, and respond to mechanical signals, such as the degree of softness of their surrounding tissue, by regulating cell adhesion molecules and associated signal transduction processes. In collaborative studies with the Department of Mechanical Science and Engineering, we have discovered HCT-8 colon cancer cells develop an in vitro metastasis-like phenotype only when exposed to substrates resembling the stiffness range of target organs such as the liver, but not when exposed to conventional tissue culture plastic surfaces. This new finding suggests the onset of metastasis may occur, in part, through mechanosensing regulation of cell adhesion receptors and provides a new paradigm for exploration of novel drugs for the treatment of metastatic cancer.
