The Miceli lab is focused around two main research topics: T cell biology and Duchenne Muscular Dystrophy (DMD). DMD is a lethal genetic disease of childhood, caused by mutations in DMD, which encodes the dystrophin protein. Without functional dystrophin, defects in sarcolemma stabilization lead to progressive muscle damage, while inherent stem cell defects limit efficiency of regeneration. Immune cells infiltrate muscle in response to damage, coordinating muscle satellite cell activation and muscle regeneration. In the face of the chronic damage in DMD, inflammation also drives fibrosis, promoting scarring and further limiting muscle regeneration. Progressive muscle weakness leads to loss of virtually all muscle function, respiratory and cardiac failure, and death between ages 20-30. The Miceli lab works closely with the CDMD clinic, clinical trials population and industry partners to use DMD clinic and clinical trial tissue sample to model human DMD, screen for new drugs/targets, and assess therapeutic efficacy and mechanisms of action and immune consequences of dystrophin replacement and immune modulating therapies.
Because DMD patient biopsy tissue is of limited availability, we are developing and applying technology for robust assessment of single cell multi-parameter immune and muscle lineage cell surface marker and gene expression, including TCR/BCR cell V region usage from cryopreserved PBMC, and frozen muscle biopsy tissue. Additionally, we developed patient mutation specific DMD skeletal muscle and cardiac culture models. We have active collaborations with industry partners involved in dystrophin replacement/rescue and immune suppression in DMD, and access to remnant trial tissue and clinic samples for our studies. By examining the consequences of therapeutics on immunity, muscle regeneration, fibrosis and tissue tolerance in human DMD, we hope to identify therapeutic mechanism of action and efficacy, cell and molecular targets for drug discovery, and potential barriers to successful treatment. We hypothesize that these studies will identify novel immune and myogenic drivers of muscle regeneration, fibrosis and immune tolerance in human DMD.
Dr. Miceli is a professor in the Department of Microbiology Immunology and Molecular genetics. She received her BA from UCSD in Biochemistry and Cell Biology, her PhD from Duke University studying the role of T cells in human kidney allograft rejection (Olja Finn, mentor) and did postdoctoral work at Stanford elucidating molecular mechanisms of CD4, CD8, Lck and TCR coreceptor functions (Jane Parne’s laboratory). In her own laboratory her group has identified mechanisms and modulators of TCR signal specificity and T cell function, with broad application to signal transduction in general. In 2007, with colleagues, r. Miceli founded the Center for Duchenne Muscular Dystrophy (CDMD), which formed and catalyzed new DMD team science approaches to translational research, drug discovery, and clinical trial development on campus and nationwide. Combining her expertise in these areas she is now focused on dystrophin replacement therapies and immune drivers of regeneration, fibrosis and muscle tissue tolerance.
