Contributions to Science
1. First to Describe the Inflammatory Cytokine Response to Severe Sepsis, Burns and Endotoxicosis. While working in the laboratories of Dr. Stephen Lowry and Anthony Cerami at Cornell Medical College and Rockefeller University between 1987-1994, Dr. Moldawer and his collaborators made significant contributions to our understanding of the ‘cytokine storm’. Dr. Moldawer and the laboratory were the first to describe the plasma appearance of IL-6, soluble TNF receptors, sIL-1RII, and IL-1ra, and were the first to show that soluble TNF receptors and IL-1ra could be used to block excessive TNF and IL-1 production during sepsis.

2. First to Describe the Role That Proinflammatory Cytokines Like IL-1, TNF and IL-6 Produced During Inflammation can Contribute to Cachexia. Dr. Moldawer’s Ph.D. thesis conducted with Kent Lundholm in Göteborg, Sweden, focused on the role of inflammatory cytokines in cancer cachexia. Since leaving Sweden and moving to New York and then Gainesville, Dr. Moldawer continued to pursue the investigation of how cytokines regulate skeletal muscle protein balance. Dr. Moldawer was the first to show that in acute models of inflammation, IL-1 and not TNF was responsible for the loss of skeletal muscle protein (Gershenwald, PNAS). Subsequent studies revealed that it was the IL-1-induced production of IL-6 that was responsible for both the skeletal muscle wasting and the hepatic acute phase protein response.

3. First to Describe the ‘Genomic Storm’ in Human Total and Enriched Leukocyte Populations After Trauma, Burns and Leukocytosis. In 2001, Dr. Moldawer joined the Inflammation and Host Response to Injury Consortium (Glue Grant) as a Steering Committee member and Core Director. The goal of the Program was to describe in its entirety the genome-wide response to trauma, burns and endotoxicosis, and to relate those changes to clinical outcomes. The concept then and now is that by understanding how the leukocyte (PMN, monocyte and lymphocyte) genomic response differs in patients who survive or expire from their trauma or burn could not only lead to novel diagnostics but also novel therapeutic approaches.

4. First to Describe the Expansion of MDSCs after Sepsis and their Contribution to the Development of a Persistent inflammatory/Immunosuppressive and Catabolic Syndrome (PICS). In 2012, Drs. Moldawer and Frederick A. Moore first proposed that with earlier diagnoses and more standardized supportive therapy, severe sepsis was no longer ending in MOF and early hospital death, but a new phenotype of post-sepsis patients is presenting with prolonged hospitalizations and chronic critical illness. We have more recently proposed that this chronic critical illness and PICS is secondary to the expansion of myeloid derived suppressor cells, a novel population of immature myeloid cells that we first described in 2007 which is responsible for both the chronic inflammation and immunosuppression.

5. Development of Novel Strategies to Prevent Sepsis in the Neonate. We have documented as has others that the two highest cohorts of patients at risk of developing sepsis, and have the highest mortality rates are the very old and the very young. Premature infants are at elevated risk of developing both early and late sepsis, as well as necrotizing enterocolitis.
