We have several areas of research interest broadly in the area of immunomodulation using micro/nanoparticles and other carrier systems. This can include development of traditional vaccines, therapeutic autoimmune vaccines and classic drug delivery platforms targeted to bacterial, viral or parasitic host cells. To this end, we also seek to develop new materials and platforms optimal for use in modulating immune responses as well as developing scalable production of micro/nanoparticles.
We are interested in studying diabetic vasculopathies. Patients with type 2 diabetes mellitus or metabolic syndrome have aggressive forms of vascular disease, possessing a greater likelihood of end-organ ischemia, as well as increased morbidity and mortality following vascular interventions. Our long term research aims to change the way we treat arterial disease in diabetes by:
- Understanding why arterial disease is more aggressive in diabetic patients, with a focus in redox signaling in the vasculature.
- Developing targeted systems using nanotechnology to locally deliver therapeutics to the diseased arteries.
Our research focuses on both fundamental and applied study of soft materials and nanomaterials, develop fabrication approaches to enable hybrid integration of multi-materials towards high-performance electronic and photonic systems, innovate new technology that can intelligently immerse electronics and photonics into biological systems, and create new tools and devices to address unmet clinical needs and improve human healthcare. Our lab fosters a collaborative environment that converges expertise/interests from various backgrounds including materials science and engineering, electrical engineering, physics, chemical engineering, mechanical engineering, and biomedical engineering. We provide hands-on learning, enjoy making practical tools, and aspire to transform scientific advancements into societal solutions.
What if you can target and deliver a drug directly to the side of disease in the body? It is possible, when you use smart living creatures pro-inflammatory response cells, such as monocytes, T-lymphocytes or dendritic cells. You can load these cells with the drug and inject these carriers into the blood stream. They will migrate to the inflammation site (for example, across the blood brain barrier) and release the drug. Thus, you can reduce the inflammation and protect the cells (for example, neurons) in patients with Parkinson’s and Alzheimer diseases.

Biochemistry & Biophysics
The Button lab in the Department of Biochemistry and Biophysics is part of the Marsico Lung Institute. Our lab is actively involved in projects that are designed to define the pathogenesis of muco-obstructive pulmonary disorders and to identify therapies that could be used to improve the quality of life in persons afflicted by these diseases. In particular, our research works to understand the biochemical and biophysical properties of mucin biopolymers, which give airway mucus its characteristic gel-like properties, and how they are altered in diseases such as Asthma, COPD, and cystic fibrosis.
The broad aim of research in the Fenton Laboratory is to develop and evaluate synthetic drug delivery platforms to treat neurodegenerative disorders in the brain using RNA therapeutics. RNA therapeutics represent a particularly promising class of therapeutics for neurodegenerative management given their ability to tune levels of specific protein expression in living systems. For example, protein downregulation can be achieved by administering short interfering RNAs (siRNAs); alternatively, proteins can be upregulated by messenger RNA (mRNA) administration. Despite this promise, fewer than 0.05% of the world’s clinically approved drugs are RNA therapeutics, and their translation to neurodegenerative disorders in the brain warrants further study at the fundamental and clinical levels.
To address these challenges, our group focuses on the discovery and development of molecular carriers and technology platforms to improve the targeting, safety, and efficacy of RNA drugs within target cells. Specifically, our group leverages an interdisciplinary approach to develop lipid nanoparticles (LNP) as well as soft matter hydrogel platforms that can serve as carrier systems and/or drug delivery models for RNA drugs. Further, our group also explores the development of technological platforms to further expand the potential of RNA drugs within resource limited settings. Lastly, given that mRNA drugs can be engineered to encode for virtually any polypeptide or protein based antigen, our group also aims to leverage our platformable LNP technologies for the study and prevention of cancers and infectious disease. In undertaking such an approach, the goal of our research is to equip students with fundamental skillsets for the development of next generation drugs while simultaneously developing clinically-relevant carrier platforms and technologies for the study, prevention, and treatment of human disease.

Genetics & Molecular Biology
My research focus centers on retinal gene/drug therapy using nanotechnologies. My laboratory is interested in developing gene therapies for inherited blinding diseases and eye tumors. We are particularly interested in understanding the gene expression patterns that are regulated by the cis-regulatory elements. We utilize compacted DNA nanoparticles which have the ability to transfer large genetic messages to overcome various technical challenges and to appreciate the translational potential of this technology. This multidimensional technology also facilitated targeted drug delivery. Currently, we are working on the design and development of several specific nano formulations with targeting, bioimaging and controlled release specificities.
Imagine a naturally intelligent therapy that can seek out and destroy cancer cells like no other available treatment. In the Hingtgen Lab, we are harnessing Nobel Prize-winning advancements to create a new type of anti-cancer treatment: personalized stem cell-based therapies. We use a patient’s own skin sample and morph it into cells that chase down and kill cancer. We take advantage of a little-known aspect of stem cells- they can home in on cancer by picking up a signal through receptors on the cell surface. All the while, the therapeutic stem cells are pumping out potent anti-cancer drugs that selectively kill any cancer cell nearby while leaving the healthy brain unharmed. Our initial studies focused on aggressive brain cancers, however we quickly expanded our testing to a variety of cancer types. Working at the interface of basic science and human patient testing, our ultimate goal is to translate this novel approach into the clinical setting where it can re-define treatment for cancers that currently have no effective treatment options.
Microbiology & Immunology
Our lab works with adeno-associated viral vectors for both the characterization of vector and host responses upon transduction and as therapeutic agents for the treatment of genetic diseases. In particular, we tend to focus on the 145 nucleotide viral inverted terminal repeats of the transgenic genome and their multiple functions including the replication initiation, inherent promoter activity, and stimulation of intra/inter molecular DNA repair pathways. The modification of the AAV ITRs by synthetic sequences imparts unique functions/activities rendering these synthetic vectors perhaps better suited for therapeutic applications.

Our dynamic group are broadly involve in three topics: (i) prevention of infectious diseases by harnessing interactions between secreted antibodies and mucus, (ii) immune response to biomaterials, and (iii) targeted delivery of nanomedicine. Our group was the first to discover that secreted antibodies can interact with mucins to trap pathogens in mucus. We are now harnessing this approach to engineer improved passive and active immuniation (i.e. vaccines) at mucosal surfaces, as well as understand their interplay with the mucosal microbiome. We are also studying the adaptive immune response to polymers, including anti-PEG antibodies, and how it might impact the efficacy of PEGylated therapeutics. Lastly, we are engineering fusion proteins that can guide targeted delivery of nanomedicine to heterogenous tumors and enable personalized medicine.
