Title: “Predicting the Effects of Engineering Immune Cells Using Systems Biology Modeling”

Abstract:

Systems biology approaches, including computational models, provide a framework to test biological hypotheses and optimize effective therapeutic strategies to treat human diseases. In this talk, I present recent work in modeling signaling in cancer-targeting immune cells, including CAR T cells at Natural Killer cells. Chimeric antigen receptors (CARs) are comprised of a variety of different activating domains and co-stimulatory domains that initiate signaling required for T cell activation. There is a lack of understanding of the mechanisms by which activation occurs. We apply mathematical modeling to investigate how CAR structure influences downstream T cell signaling and develop new hypotheses for the optimal design of CAR-engineered T cell systems. Natural Killer cells also provide a useful platform for targeting cancer cells. However, NK cells have been shown to exhibit reduced killing ability with prolonged stimulation by cancer cells. We use a combination of mechanistic model, optimal control theory and in silico synthetic biology to investigate strategies to enhance NK cell-mediated killing.

Title: “Patients, Providers and Data: How the EMR and Data Science are Changing Clinical Care”

Abstract:

The electronic health record (EHR) is a powerful application of Systems Engineering to healthcare. It is a byproduct of a host of pressures including cost, consolidation of providers into networks, uniform drivers of quality, and the need for timely care across disparate socioeconomic and geographic landscapes within health systems. The EHR is also a fulcrum for innovation and one of the most tangible examples of how data science affects our health and health care. In this talk I will showcase projects from my lab that demonstrate the multi-disciplinary nature of biomedical informatics/data science research and translation using the EHR, and our current understanding of its potential from my perspective as a pediatrician, a researcher in biomedical informatics, a Chief Information Officer, an educator, and an advisor to local and international policy. I will describe advances in applying human factors engineering to support medical documentation and generic prescribing, approaches to improve medication safety, and innovations to support precision medicine and interoperability. I will present our efforts to integrate EHR-enabled data science into the Vanderbilt health system and provide a vision for what this could mean for our future.

Title: “Stem Cell Fate is a Touchy Subject”

Abstract:

The success of regenerative cell therapy relies on the integration of a functional vascular system within the redeveloping tissue, to mediate the exchange of oxygen, nutrients and waste. Although the advent of human induced pluripotent stem cells (hiPSCs) has accelerated progress towards this goal, owing to their potential to generate clinically relevant scales of patient-specific cells, techniques to drive their specification mainly rely on chemical cues. In this seminar, I will discuss engineering strategies to control the complex stem cell extracellular milieu, emphasizing the importance of mechanical cues during hiPSC development, specification and downstream functionality as it relates to vascular differentiation.

Title: “Musculoskeletal Tissue Engineering”

 

Abstract:

The field of Tissue Engineering/Regenerative Medicine is replete with advances that have been translated to human use. However, our job is not done when a treatment for a specific disease or traumatic event has been invented and translated to humans. In order to be available to the population nationwide (or globally), our novel treatment must be manufactured, transported to the user, and administered by a physician to that user. In addition, novel treatments for rare diseases may not be amenable to manufacture by a company, and perhaps would be best manufactured by an academic medical center. I will discuss these issues that occur after successful translation of a novel treatment to human use, as well as potential strategies to address them.

Title: “Repurposing bacterial two-component systems as sensors for synthetic biology applications”

Abstract:

Two-component systems (TCSs) are the largest family of signal transduction pathways in biology, and a treasure trove of biosensors for engineering applications. Though present in plants and other eukaryotes, TCSs are ubiquitous in bacteria. Bacteria use TCSs to sense everything from metal ions to carbohydrates and light, and activate responses such as biofilm formation, antibiotic-resistance, and virulence. Despite their importance, the vast majority of TCSs remain uncharacterized. The major challenges are that most bacteria cannot be cultured nor genetically manipulated in the laboratory, and that many TCSs are silenced by poorly-understood gene regulatory networks in laboratory conditions. We have recently developed synthetic biology technologies to address these challenges. In particular, we have developed dual inducible promoter systems that allow us simultaneously express both TCS proteins to optimal levels in the model Gram-negative and Gram-positive bacteria E. coli and B. subtilis. In addition, we have developed a method to modularly interchange the DNA-binding domains of response regulator proteins, enabling unknown or silent TCS output promoters to be replaced with well-characterized alternatives. Finally, we have developed a method to rationally tune the amount of input signal required to activate a TCS over several orders of magnitude by introducing mutations that specifically alter the intrinsic phosphatase activity of the sensor histidine kinase protein. Using these methods, we have repurposed cyanobacterial TCSs to function as optogenetic tools with wavelength specificities from the ultraviolet (380 nm) to the near infrared (770 nm), engineered gut bacteria that diagnose colon inflammation in mice, and discovered a novel pH-sensing TCS in the genome of Yersinia pestis, the causative agent of bubonic plague. Additionally, we have constructed a library of >500 uncharacterized TCSs from the human gut microbiome, which we are screening for novel sensors of gut metabolites and diseases in humans. Finally, we are using our methods to develop new anti-virulence compounds that inhibit TCSs that regulate pathogenesis in major human pathogens. Our work is accelerating fundamental microbiological discoveries and has broad applications in synthetic biology.

Title: “Immunomodulatory Biomaterials for Limb Salvage”

Abstract:

Diabetes and peripheral arterial disease affect hundreds of millions of people worldwide. Patients with these conditions frequently develop chronic wounds on the lower limbs that lead to amputation, with a 5-year mortality rate as high as 77%. Macrophages, the primary cell of the innate immune system, are critical regulators of angiogenesis and wound healing. Their dysfunction is strongly implicated in arterial dysfunction, limb ischemia, and poorly healing chronic wounds. The goal of the Biomaterials and Regenerative Medicine Laboratory at Drexel University is to understand the mechanisms by which macrophages orchestrate successful angiogenesis and tissue regeneration and to develop novel biomaterial strategies that apply these principles to pathological situations, in order to ultimately prevent limb amputation. This talk will focus on the effects of temporal changes in macrophage phenotype on angiogenesis, the design of biomaterials and drug delivery systems to modulate macrophage phenotype for enhanced angiogenesis, and the development of macrophage phenotype-related biomarkers to assist in clinical decision making for a personalized medicine approach to wound care.

Title: “High-throughput T Cell Repertoire Profiling Enabled Systems Immunology and Immune Engineering”

 

Abstract:

T cells are important to the initiation, prevention, and cure of many diseases. For example, various T cells based cancer immunotherapies have been quite effective in treating several types of cancers. However, a significant fraction of patients do not respond. A comprehensive understanding of the complexity of the T cells repertoire in health and diseases not only provide underlying mechanisms but also new therapeutic targets. In the past several years, we have developed several tools to profile the T cell repertoire from T cell receptor diversity to T cell receptor affinity to multi-dimensional profiling of single T cells in high-throughput. In this talk, I will first introduce these tools and then give examples on how we use them to answer some of the fundamental questions in systems immunology, which in turn help us design new approaches in immune engineering.
