Overview

Oral squamous cell cancer (OSCC) is the sixth most common cancer worldwide and accounts for 2% of all malignancies in the USA. In this year alone, 40,000 men and women will develop OSCC, and unfortunately, only two-thirds of these OSCC patients will survive more than five years. While the past decades have seen advances in ablative/reconstructive surgery, radiation therapy, and chemotherapy, the overall survival rate of OSCC patients has not improved significantly, and there are multiple co-morbidities which arise from treatment which may negatively affect quality of life. Thus, there is a real need for innovative new approaches to treating oral squamous cell cancer. 

Immunotherapy has arisen as a novel treatment modality for several cancers, and biomaterials-based cancer immunotherapy platforms are currently being developed in our laboratory. Our goal is to evaluate these promising technologies for use in oral squamous cell carcinoma. The overall hypothesis is that biomaterials-based constructs able to provide appropriate spatiotemporal presentation of bioactive factors to key immune cells can induce anti-tumor immunity.

The focus of our current research is to develop novel material-based immunotherapies for the treatment of head and neck cancer and explore mechanisms of how this approach may synergize with other modalities of treatment such as chemo/radiation therapy. The paradigm of in situ cell programming using biomaterials is also being utilized in a separate research project in collaboration with MIT, exploring the use of layer-by-layer technology to deliver bioactive factors for the enhancement of craniofacial bone regeneration.

We are currently working to characterize a new preclinical mouse models of OSCC, determine the effectiveness of implantable cancer immunotherapies for treating OSCC, and to explore any synergistic effects that arise by combining these materials with other immunotherapeutic strategies.

Overall, these studies are anticipated to enhance our understanding of the role dendritic cells and tumor-specific cytotoxic T cells play in the treatment of OSCC, and may also contribute to the development of novel immunotherapies for OSCC.

    Printing and Regenerating Fractured Bone Using Antioxidant Materials

    Printing and Regen Photo

    Bone fractures are challenging to heal because of the sudden loss of bone and vasculature. Current treatments are inadequate because metal-based devices for bone fixation and biopolymer-based devices for bone regeneration do not stimulate rapid bone formation once implanted or produce weak or improperly healed bone. This inability to rapidly repair the large volume of lost bone and vasculature after trauma leads to increased reactive oxygen species (ROS) and oxidative stress at the fracture site, which impedes normal bone healing. Our long-term goal is to develop clinically useful, regenerative devices that accelerate bone healing.

    Our objectives for this proposal are to (1) uncover material properties that reduce ROS and enhance antioxidant, osteogenic, and angiogenic capacity and (2) develop novel nano-scale surface chemistries and 3D architectures that are fabricated for fixative and resorbable devices that stimulate rapid biomineral and vascular formation in fracture sites. We will develop 3D nanofabrication and printing methods to create new amorphous silicon oxynitrophosphide (SiONPx) based devices that provide structural and antioxidant support for rapid bone healing via release of ionic Si and rapid formation of a surface hydroxyapatite layer for bone attachment, respectively. Our central innovation is the development of a new class of implantable devices that can potentially adapt to the challenging oxidative environment within a bony defect. Once such devices become clinically available, there is the promise that a significant advance will have been made toward translation of these devices and fabrication methods in patients needing rapid healing of fractures. These results will have a positive impact in supporting future clinical trials of new antioxidant materials on biomedical devices that can reduce patient healing time, reduce medical care cost, and increase the quality of newly formed bone in traumatic fractures.

    This proposal builds on our successes in developing a nanostructured material we call “MultiDomain Peptides” or MDPs. Amongst the many discoveries during our first funding period, we found that these hydrogels have remarkable properties in vivo, in particular: 1) The MDP amino acid sequence can be tailored for rapid or slow degradation. 2) The hydrogel is entirely infiltrated by host cells within 7 days where the large number of cells interacting with the MDP matrix provides for powerful and rapid response to the matrix. 3) No fibrous encapsulation is observed up to 42 days in vivo allowing for good communication between our nanostructured matrix and the biological system. 4) Biomimetic amino acid sequences can be added to the base MDP structure allowing it to provoke desired biological responses such as angiogenesis and neurogenesis. Published data from our previous funding period and unpublished preliminary data presented here demonstrate the extremely powerful angiogenic and neurogenic properties of carefully designed MDPs which is unprecedented elsewhere in the literature and is the basis for the current proposal. A key feature of our approach is that the MDP hydrogel is composed of just a single designed, synthetic peptide. There is no need for additional growth factors or cells, either of which increases the challenge of clinical translation due to unforeseen and undesirable biological responses such as immune reaction, host rejection or tumor formation. Our interdisciplinary team combines expertise in chemistry, materials science, nanotechnology, neuroscience and clinical medicine. We will generate data that will provide the framework for further advances in nanostructured tissue engineering generally as well as advances specific to neural regeneration.

    Sjogren’s Syndrome (SS) is a common auto-immune disease with a prevalence of 0.2 – 2.7% without a known cure. Lymphocytes infiltrate exocrine salivary and lacrimal glands to disrupt secretion leading to dry eye and/or mouth. SS affects a patient’s quality of life through difficulty swallowing, risks of dental caries, and often depression. Immune infiltrates primarily target secretory acinar cells leading to atrophy and decreased secretory output. T-cells were long believed to be the primary drivers of SS, but studies showed higher ratios of B-cells to T-cells in advanced disease stages. Additionally, the high prevalence of Th17 cells in glandular tissue and blood of patients with SS suggests an important role for T- helper cells and B-cells, but the mechanisms driving immune localization remain unknown. Much of our understanding of SS etiology comes from analysis of blood or salivary glands by flow cytometry. Although cytometry studies identified B and T lymphocyte subpopulations, a knowledge gap arises from the unmet need for an unbiased full immune profiling of glands affected by SS. Single-cell sequencing of the entire gland performing simultaneous whole transcriptome and variable diversity and joining genes (VDJ) analysis can identify the full repertoire of immune cell populations, including rare cells, and their clonality in SS salivary tissue. It also can map the true abundance of the Th17 population in individual patient samples and their relation to other immune cell types. Because the identification of the immune cell repertoire present in SS salivary glands does not provide information on the way they contribute subsequent loss of salivary function, it is critical to perform functional studies to assess the link between presence of these cells and loss of secretion. We will initiate these studies with Th17 cells, then expand them to other immune populations as they are identified by genomic sequencing.

    We hypothesize that Th17 cells along with other yet unidentified immune cells contribute to the loss of salivary gland function by reducing the secretory capabilities and increasing cellular death of acinar cells. We will use single-cell RNA Sequencing to broadly profile the immune microenvironment of affected salivary glands in SS patients and then study the functional link between pathogenic immune cells and reduced secretory function using advanced 3D culture systems.

  • Biomaterials-Based Cancer Immunotherapy

    Biomaterials-Based Cancer Immunotherapy

    Biomaterials Photo

    Head and neck squamous cell cancer (HNSCC) is the sixth most common cancer worldwide and almost 50,000 men and women will develop HNSCC this year in the US alone. Unfortunately, only two-thirds of these HNSCC patients will survive more than five years, a statistic that has not changed in decades despite advances in surgery, radiation therapy, and chemotherapy. Given the well-known co-morbidities and recurrence rates associated with conventional treatments, there is a real need for innovative new approaches to treating HNSCC. Cancer immunotherapy (such as FDA-approved immune checkpoint antibodies) has arisen as an exciting treatment modality for several advanced-stage cancers including HNSCC, with the potential to generate specific and durable anti-tumor responses, although typically only in about 15-20% of patients.

    Recently, a new class of immunotherapeutics based on synthetic cyclic dinucleotides (CDN) have been found to produce strong anti-tumor responses in preclinical models through the Stimulator of Interferon Genes (STING) pathway. However, to date CDN monotherapy has shown minimal efficacy in preclinical models of HNSCC, requiring multiple-injections and concomitant administration of immune checkpoint antibodies targeting the PD-1/PD-L1 axis for tumor rejection. In response to this challenge, our lab has developed a novel peptide nanofiber hydrogel-based platform for intratumoral CDN delivery called “STINGel” which has shown impressive and surprising efficacy in a challenging murine model of HNSCC.

    Our goal is to determine the underlying mechanisms driving STINGel effectiveness in HNSCC. The overall hypothesis of this proposal is that intratumoral injection of STINGel renders immunologically refractory tumors sensitive to immune-mediated killing through multiple mechanisms including: 1) Prolonged release of CDN, 2) STINGel-driven recruitment of critical antigen presenting cells (APCs) to the site of injection, and 3) enhanced Type-1 interferon (IFN) response in both tumor cells and APCs within the tumor microenvironment (TME). Overall, this work is anticipated to enhance our understanding of the mechanisms by which STINGel can reverse resistance to immunomodulatory monotherapy in solid tumors and provide insights into how the adverse tumor microenvironment can be rendered more susceptible to immunotherapy.

  • Development of a Compromised Maxillofacial Wound Healing Model for Bone Graft Evaluation

    Development of a Compromised Maxillofacial Wound Healing Model for Bone Graft Evaluation

    Development of Compromised Photo

    Although a wide range of animal models have been employed for the evaluation of bone tissue engineering technologies, they generally involve evaluation of tissue regeneration in an optimized wound bed (e.g., an aseptic, surgically-created bony defect in a healthy soft tissue envelope). However, such optimized bony defects do not adequately reflect the complexity of the wound bed in which regenerative therapies generally will be applied clinically, such as contaminated traumatic defects, post-radiation resection sites, or multiply- operated sites.

    Accordingly, a tremendous need exists for the development of a pre-clinical animal model that suitably replicates the challenging compromised wound environment encountered in clinical scenarios (1) to guide our collective understanding of the mechanisms underlying the challenges to tissue regeneration in the compromised wound and (2) to facilitate rigorous pre-clinical evaluation of regenerative therapies to overcome the challenges of compromised maxillofacial defects.

    We seek to build upon our established rabbit mandibular defect model to develop a new pre-clinical model of compromised maxillofacial wound healing for application as a clinically-relevant platform to meet these needs.
