Rama Mallampalli, MD
- S. Robert Davis Chair of Medicine Professor and Chair, Department of Internal Medicine Director, ALI Center
The Acute Lung Injury (ALI) Center, directed by Rama Mallampalli, MD, is a specialized research center focused on understanding the basic lung biology of pulmonary inflammation and development of novel therapeutics. Through collaborative projects involving clinical faculty and experts in lung biology, the laboratory spans the spectrum of discovery including basic, translational and clinical research.
Dr. Mallampalli is an internationally recognized investigator in the area of lipid metabolism and ubiquitin-mediated proteolysis as it relates to inflammation lung injury and cell metabolism. His research program discovered a unique model for the molecular behavior of ubiquitin E3 ligase subunits that control inflammation. Dr. Mallampalli’s laboratory designed, synthesized and tested the first-in-class genus of ubiquitin E3 ligase (F box) inhibitors that modulate proteolysis thereby inhibiting inflammation in preclinical models of ALI and multi-organ failure. He currently leads an NIH Program Project grant (P01) in ALI and holds multiple NIH R01 grants to understand the basic pathobiology of inflammatory lung disease to develop drug therapies to combat injurious inflammation.

The laboratory research focuses on identifying the molecular mechanisms that regulate acute lung injury. We utilize biochemical and omics approaches to examine lung injury using in vitro and in vivo models with an emphasis on understanding post-translational modifications and the ubiquitin system. We then leverage these discoveries to develop novel therapeutics.
COVID-19 and ARDS (Project 1)
Utilizing human samples from COVID-19 patients, novel small animal models of COVID-19 ARDS (acute respiratory distress syndrome) and cell-based systems, we are studying the host response to COVID-19 and those factors that confer resiliency to SARS-CoV-2 infection.
Immunosuppression in Acute Lung Injury (Project 2)
A heterogenous disease, ARDS is characterized by an early inflammatory stage and a late immunosuppressed stage, whereby immune responses are dysregulated, and hosts are susceptible to secondary infection.
Ubiquitin E3 Ligases in ARDS (Project 3)
Ubiquitination is a post-translational modification that tags proteins for degradation or alternate cellular trafficking. Alterations in protein abundance or “proteostasis” plays an important role in numerous cell functions including response to external stimuli and regulation of inflammation. Through study of the molecular mechanisms by which E3 ligases regulate disease, we aim to identify therapeutic targets to combat ARDS.
Interferon Signaling in Viral Infection (Project 4)
Examination of the posttranslational modification of interferon receptors to alter interferon signaling and alleviate viral replication and pathogenesis.
