Research Interests

Dr. Good’s laboratory focuses on the cellular and molecular mechanisms involved in the development of necrotizing enterocolitis (NEC). Specifically, she is interested in the anti-inflammatory properties of breast milk and amniotic fluid on the neonatal intestinal epithelium in the pathogenesis of NEC. Utilizing a mouse model of NEC, she studies the mechanism by which breast milk and amniotic fluid prevent the disease. She has shown that amniotic fluid inhibits Toll-like receptor (TLR4)-mediated pro-inflammatory signaling in the fetal and neonatal intestine and prevents NEC via epidermal growth factor receptor signaling (PNAS, 2012). She has also developed a large animal model of NEC with premature piglets and has begun testing therapeutics in this model (AJP-GI and Liver, 2014). She is also particularly interested in understanding the anti-inflammatory properties of breast milk on the intestine and seeks to determine the mechanism that mediates the protection. She has shown that two ingredients found in breast milk, epidermal growth factor (Mucosal Immunology, 2015) and human milk oligosaccharide (British Journal of Nutrition, 2016) mediated protection against experimental NEC by inhibiting intestinal inflammation. By identifying the components of breast milk that are anti-inflammatory, she hopes to identify novel protective and treatment strategies for necrotizing enterocolitis. In addition to her basic science investigation, Dr. Good is the primary investigator on an IRB protocol entitled, “Identifying Premature Infants who are at High Risk for NEC.” The aim of this study is to evaluate the molecular signature and genetic susceptibility of premature infants with and without NEC. The long term goal of this study is to be able to intervene earlier in the disease process and prevent the development of this devastating disease altogether.

Current Projects

Our lab focuses on the intestinal mucosal immune response involved in the pathogenesis of necrotizing enterocolitis (NEC). Specifically, we are interested in:

– Determining the components of breast milk that are protective against NEC.

– Understanding the signaling pathways that are involved in NEC development.

– Predicting the infants at risk for NEC.
