Our Research

The Wynn laboratory is focused on the investigation of neonatal-specific innate immune cellular function and inflammatory signaling during sepsis as well as development of novel therapeutic immunomodulatory strategies aimed at improving sepsis outcomes.

We employ both preclinical mechanistic investigations in association with observational human studies to improve our understanding of the neonatal-specific host response to sepsis. We use a wide variety of molecular and genetic techniques to interrogate the immune response via in vivoex vivo, and in vitro approaches. Applications of our work include improving the accuracy of sepsis diagnostic methods, identification of prognostic and clinical stratification markers, and discovery of potential opportunities for translational interventions aimed at improving infection-related outcomes.

nSOFA Calculator

Guided by data, we developed and tested an objective, electronic health record (EHR)-automated, Neonatal Sequential Organ Failure Assessment (nSOFA) scoring system to predict mortality from LOS in premature, very low birth weight infants.

Human Studies

Our sepsis-targeted observational human neonatal studies have been performed in parallel with our mechanistic murine studies. We have three active, large-scale, human neonatal sepsis research projects:

Preclinical Studies

We developed and validated the gold standard of murine neonatal sepsis modeling: the cecal slurry model of generalized peritonitis.
