Research Interests

My overarching research goal is to develop a better understanding of how the immune system contributes to cutaneous health and disease and to leverage these mechanistic insights to develop new avenues for therapy. My laboratory focuses on how immune cell populations integrate molecular and environmental signals from the cutaneous microenvironment to provide protection against cancer, infection, wounding, or autoimmune responses mistakenly trigger maladaptive immune responses during autoinflammatory/autoimmune skin diseases. This knowledge will lead to logically designed, effective therapeutic strategies to either strengthen antimicrobial and/or anti-cancer responses in the skin, enhance wound healing and/or skin regeneration, or diminish auto-inflammatory or autoimmune phenomena. My laboratory research program has three major directions:<

1. How do neural inputs modulate cutaneous immune responses? We are finding that neuroendocrine (glucocorticoids) and sympathetic (adrenergic) nervous system stimuli selectively inhibit distinct inflammatory stimuli, and endogenous glucocorticoids and beta-adrenergic stimuli suppress psoriasis in a mouse model. Our goal is to use transgenic models to better define the cell populations that utilize these neural inputs as rheostats on immune<

activation to develop more targeted therapies. We are also finding that signals from the sympathetic nervous system also are required for cutaneous regeneration after injury.<

2. How do we leverage cell to cell interactions within the cutaneous immune microenvironment to enhance wound healing, skin regeneration or cutaneous host defense? We have identified several ways to modulate cutaneous immunity in several different models. Specific projects include:<

– We have also found that a biomaterial that activates macrophages and lymphocytes type 2 immune immune responses in in the skin can directly trigger skin regeneration. What are the signals produced by these immune cells that can prevent fibrosis and activate skin regeneration.<

– We have found that cGAS-Sting activation subverts host defense against Staphylococcus aureus infection through type I IFN production, and type I IFN can also be modulated by changing lipid concentrations in the skin to enhance host resistance to bacterial toxins. We are now studying novel approaches to alter lipid composition to improve cellular defense strategies against skin pathogens.<

– We are finding that deletion of a key interferon regulatory pathway from the host microenvironment leads to enhanced growth of melanoma and other tumors implanted subcutaneously, but deletion of that interferon regulatory pathway from tumor cells themselves enhances anti-tumor immune responses. Understanding how immune factors affect tumor growth in a tumor cell-intrinsic vs tumor cell extrinsic manner will be used to improve cancer immunotherapies.<
