Summary

In recent years, the decades-long promise of tumor immunotherapy has finally begun to come to fruition. Checkpoint blockade, for example, represents a critically important intervention for potentiating the antitumor immune response. In these therapies, blockade of T cell intrinsic negative regulators (such as CTLA-4 and PD-1 signaling) releases the brake on effector T cells in the tumor, resulting in substantial, durable antitumor immunity, and clinical responses.

While negative regulators on the effector T cells can be relieved through these interventions, effector T cells still face a variety of cell extrinsic modes of immune suppression, notably through suppression via regulatory T (Treg) cells. Treg cells play critical roles in preventing autoimmune responses to self tissues as well as limiting immunopathology during exuberant immune responses. However, Treg cells represent a major barrier to antitumor immunity. Many tumors recruit, activate, and expand large numbers of Treg cells, which can be specific for any number of normal, self antigens expressed by the tumor. While depletion of total Treg cells can result in autoimmune pathologies, inhibition of Treg cell stability or function has been shown to allow for local inhibition of Treg cell suppression in the tumor, while sparing normal tissues from an autoimmune response.

Thus, finding phenotypic, signaling, or functional parameters that distinguish intratumoral Treg and conventional T (Tconv) cells could shed light on mechanisms by which Treg cells could be targeted to allow for a greater antitumor response. Recent studies have found that Tconv and Treg cells have distinct metabolic requirements. Not unlike cancer cells, conventional T cells undergo aerobic glycolysis (the 'Warburg effect') when undergoing robust expansion. However, regulatory T cells utilize alternative sources of fuel. Our initial findings in the laboratory suggest that not only do intratumoral Treg cells utilize distinct fuel from their conventional brethren, but engage different metabolic pathways from Treg cells in normal tissues and lymphoid organs. This suggests that metabolic pathways, or their downstream targets, could be targeted in order to inhibit intratumoral Treg cells specifically, releasing a crucial cell extrinsic brake on the antitumor immune response. The goal is to provide alternative modalities of therapy that could be utilized alone or in combination with other immunotherapeutic strategies, to allow for robust and durable immune responses for the eradication of cancer.

Summary

Our research interests are focused on the mechanisms of cross-priming of antigens during immune responses to cancer, viruses and autoimmunity. The pursuit of this research area stems from the observations that in many situations, heat shock proteins (HSPs) are both necessary and sufficient for cross-presentation. HSPs are adept at this because of several unique properties, including their ability to:

  1. chaperone peptides;
  2. bind to HSP receptors (CD91) for endocytosis; and
  3. stimulate immune cells to up-regulate costimulation.

HSPs thus elicit remarkable immune responses specific for the peptides they chaperone. The laboratory is using these observations to examine new facets of antigen presentation and also to develop novel immunotherapies for cancer, infectious disease and autoimmune disorders.

A related area of research examines how other ligands for the HSP receptor CD91 interact with the immune system. In the past few years, we have shown that a2-macroglobulin (a2M), a CD91 ligand, though not a bonafide HSP, shares the immunogenic properties of HSPs and can elicit immune responses specific to (peptide) substrates that it chaperones. We are currently exploring the identification of naturally formed a2M-substrate complexes and the potential use of these immunogenic complexes as therapeutic agents for cancer and infectious disease.

Summary

Immunotherapy, specifically anti-PD1, has improved patient survival in a range of tumor types including head and neck squamous cell carcinoma (HNSCC) and non-small cell lung cancer (NSCLC). Despite the success of anti-PD1 therapy, only 20% of patients produce a durable response to this treatment. Further, there are some solid tumor types i.e. ovarian cancer, which yield very little therapeutic benefit from current standard of care immunotherapies. Thus, a need exists to develop additional therapeutic strategies to treat these patients, which includes evaluation of other tumor infiltrating immune cells that could further augment the CD8+ and CD4+ intratumoral T cell response. B cells represent a possible target for immunotherapy due to their predominance in the tumor microenvironment (TME) and crucial role in the immune response. However, B cell function in cancer and in the context of immunotherapy has been understudied. In fact, conclusions on an anti- or pro- tumor role for B cells in the TME remain incomplete. However, in multiple solid tumors, current evidence suggests an anti-tumor role for B cells. Specifically, detection of B cells within tertiary lymphoid structures (TLS) correlates with increased survival and immunotherapeutic response. While B cells have been identified in multiple tumor types, their complete phenotypic signature and interplay with other components within the TME have been understudied. Further, the complex composition of TLS in patient tumors is severely underappreciated, which is an overt focus of the Bruno laboratory. Specifically, we aim to understand B cell infiltration and TLS development within solid tumors to generate effective B-cell focused immunotherapies to augment the current successes of standard of care immunotherapies such as anti-PD1.

To this end, we take a multi-level approach to understanding B cells and TLS composition in human tumors. Specifically, we transcriptionally assess B cells via single cell RNAseq with paired BCR seq, we interrogate B cell subsets within patient tumors using multi-parameter flow cytometry (15-30 parameters), we locationally evaluate B cells within and outside TLS utilizing multispectral imaging (Vectra Polaris) and spatial transcriptomics (Nanostring GeoMax Digital Spatial Profiler), and we evaluate the function of B cells and their interplay with other important immune cells within the TME via micro-scale in vitro functional assays.

Summary

The Cillo Lab focuses on understanding how immune cells make cell fate decisions, how intercellular communication influences these cell fate decisions, and the ways in which cell-cell interactions shape community dynamics in the tumor microenvironment. To address these questions, we are utilizing high-dimensional systems based approaches including spectral flow cytomtery, single-cell RNAseq and spatial transcriptomics in the context of patients with solid tumors such as head and neck cancer, sarcoma, and melanoma among others. Defining the contributions of individual immune populations and their behavior in aggregate will allow us to understand how current immunotherapies promote antitumor immunity and why current immunotherapies fail in some patients. Additionally, it will enable us to identify new therapeutic targets to promote antitumor immunity in a larger proportion of patients with solid tumors.

Summary

The long-standing interests of our laboratory center on identifying specific mechanisms of human anti-tumor immunity and cancer immunosurveillance. We study T cell and antibody repertoire in cancer patients and in healthy individuals at risk for cancer and factors that influence that repertoire. We were the first to identify a human tumor antigen recognized by human T cells and antibodies, the epithelial mucin MUC1. We showed that tumors express an abnormal form of MUC1 that is recognized by the immune system as a foreign rather than a self-antigen. Studies in mice and primates showed that MUC1 was immunogenic and that anti-MUC1 immune responses can reject tumors. These studies supported multiple clinical trials of a MUC1 vaccine in patients with breast, colon, and pancreatic cancer. Most recently, we began testing a MUC1 vaccine for cancer prevention in individuals diagnosed with MUC1+ premalignant lesions. In addition to being a tumor antigen, MUC1 is an oncogene by virtue of promoting a highly inflammatory tumor microenvironment. We discovered that the tumor form of MUC1 activates NF-kB, binds p65 and translocates to the tumor cell nucleus where it binds to and activates promoters of inflammatory cytokines, such as IL-6 and TNF-a.  MUC1 has been associated with a more invasive cancer phenotype and we have recently deciphered the mechanism by showing that it forms complexes with CIN-85, also previously associated with cell motility and invasion.

While studying MUC1 and another tumor antigen that we discovered, cyclin B1, we made an important observation that many tumor associated antigens (TAA) described by their abnormal expression on cancer cells, are also abnormally expressed in other acute or chronic inflammatory conditions and are therefore more appropriately defined as disease associated antigens (DAA).  These include bacterial infections such as Mumps, viral infections such as chicken pox, and chronic inflammations such as inflammatory bowel disease (IBD). This observation helped us formulate and test a new hypothesis on cancer immunosurveillance. Working in collaboration with epidemiologists and creating appropriate mouse models, we showed that immunity to abnormal self-antigens, DAAs, is generated simultaneously with immunity to pathogens early in life in the course of febrile infections. Immune memory for DAAs contributes to effective immunosurveillance of other pathogen infections throughout life, as well as of cancer that expresses many of those same antigens. Lastly, we are pursuing an idea that the quantity and the quality of immune memory for DAAs is critical for maintaining general immune health. Using genomic and bioinformatics approaches, we are defining a gene expression signature that characterizes individuals with strong immunosurveillance ability versus those that lack that ability and designing DAA-based vaccines to promote immunosurveillance of cancer and other diseases.

Summary

I am an assistant professor of immunology at the University of Pittsburgh and member of Tumor Microenvironment Center at UPMC Hillman Cancer Center. My research focuses on the mechanisms that control cell death and how the quality of cell death can modulate the immune response, especially anti-tumor immunity. I have actively pursued research in cell death and immunology for fifteen years, at Beijing Normal University and National Institute of Biological Sciences, Beijing, China as a graduate student, St. Jude Children’s Research Hospital as a postdoc, and the University of Pittsburgh as principal investigator.

My work has initially focused on apoptosis/apoptosome and pyroptosis/inflammasome activation in macrophages, monocytes, and dendritic cells. I have identified bromoxone as a pan-inflammasome inhibitor and revealed mechanisms of inflammasome action against bacterial pathogen infection. I continued working on the programmed cell death, mainly necroptosis; I discovered the role of ESCRT- III in necroptosis and its immune responses. ESCRT-III machinery can rescue the necroptotic cells via shedding and repairing broken plasma membrane, thus, sustain cell survival. As a consequence, cells undergoing necroptosis can express chemokines and other regulatory molecules to promote dendritic cell-mediated cross-priming of CD8+ T cells. In collaboration with clinical investigators, I revealed ESCRT-III keeps cells from lysis, especially in kidneys from the transplantation procedures.

After becoming an independent researcher, I continue to work on the mechanisms of programmed cell death and its role in regulating immune responses, including auto-immunity and cancer immunology. We keep exploring novel signaling pathways of programmed cell death. We are also focusing on new drug target discoveries in the cell death pathway. Our goal is to use these targets to overcome the tumor cell death resistance upon chemotherapies. We are also deciphering the central roles of various types of programmed cell death in anti-tumor immunity, auto-immune diseases, and transplantation. We will reprogram cell death to modulate the immune response.

Summary

Understanding how extracellular signals are linked to gene expression is a fundamental challenge in biology, and more specifically, macrophage signal integration is central to understanding healthy versus aberrant regulation of inflammation. My laboratory uses quantitative approaches to address these problems, with major projects including (1) computational modeling of signaling-to-transcription in macrophages, (2) interrogating tissue-specific macrophage signaling, and (3) dissecting molecular determinants of macrophage inflammatory function. We use both data-driven and mechanistic modeling approaches to integrate transcription factor activity, global phosphorylation, and transcriptomic data to explore signaling mechanisms that shape macrophage function. In the tissue context, we use a combination of network-based approaches and hypothesis driven in vivo experiments to identify mechanisms linking tissue stimuli (e.g. cytokines and lipids) to transcription factor activity, and ultimately macrophage function. We hope these efforts will yield insights into dysregulation of signaling and inflammation, while informing therapeutic strategies.

Summary

The laboratory of Timothy Hand, PhD, is interested in the immune cells of the intestine and how they respond to the first interactions with colonizing microorganisms. How the immune system deals with newly colonizing bacteria is important, since too little immune response can lead to infection but too much can contribute to damaging inflammation. The intestine is home to the largest and densest group of microorganisms in the body and the intestinal microbiome is required for many host processes, most notably the digestion of complex carbohydrates. Therefore, maintaining a healthy relationship with the microbiome is important for the health of the host. Shifts in the intestinal microbiota and the mucosal immune response have been associated with a variety of important pediatric diseases including colorectal cancer, inflammatory bowel disease and necrotizing enterocolitis.

Our view is that the long- term relationship between the host and the microbiome can be shaped by the results of their initial interaction by the phenomenon of immunological memory. Therefore, we seek to better understand the immune systems ‘first impressions’ of the microbiota and how they are shaped by environmental factors such as diet and inflammation. Our hope is that a better understanding of how the microbiome shapes the host will lead to better therapies for pediatric disease. We also hope to harness this knowledge to improve our ability to use the immune response for therapy and augment anti-tumor immunotherapy.

Summary

Bone marrow stem cell transplantation is, for many, the only curative treatment for leukemia and lymphoma-blood cancers. From this technique, we have learned that immune cells of the donor which are transferred in the transplant can eradicate blood cancer, in the so-called graft-versus-leukemia (GVL) effect. My research work is directed to finding ways to harness this GVL immune effect to cure leukemia and lymphoma. I am particularly interested in preventing and treating post-transplant relapse which remains the major cause of transplant failure. This involves two approaches: The first is to improve the results of transplants for people with leukemia by increasing the GVL effect and decreasing the hazards of the transplant through biomarker-directed personalized medicine and adoptive cellular immunotherapy. The second is to find ways to create a new immunotherapy boosting the patient's own immune system and thus avoid the complication of transplantation altogether.

Summary

My lab is currently pursuing several projects:

1. The role of TIM-3 in CD8+ T cells 

This project currently involves the study of - TIM-3, a novel protein of the T cell immunoglobulin and mucin domain family in regulation of CD8+ T cell function during viral infection (using LCMV as a model system) and responses to syngeneic tumors. We are also interested in elucidating signaling pathways downstream of TIM-3.

2. The role of TIM-3 in regulatory T cells (Treg)

Work from our lab and others has shown that expression of TIM-3 is associated with acquisition of a more potent "effector" Treg (eTreg) phenotype. We are studying how this phenotype contributes to the effects of Treg on immune responses to viral infection and tumors, using both mouse models and correlative studies in humans.

3. Regulation of T cell and mast cell activation by PIK3IP1/TrIP, a novel regulator of PI3K

Dr. Kane's lab has found that a novel transmembrane protein known as PIK3IP1 (PI3K-interacting protein 1) or TrIP (transmembrane inhibitor of PI3K) is expressed in both T cells and mast cells. This protein appears to restrict early activation of both cell types. The lab is currently characterizing mice with inducible deletion of TrIP to better understand how this protein functions in vivo, especially in the context of syngeneic tumors.

Dr. Kirkwood’s research focuses upon melanoma immunobiology, therapy and prevention. His translational studies established the first effective adjuvant therapy of melanoma, and identified the immunological basis of this therapy, and are now probing the role of molecularly targeted agents (BRAF, MEK, and PI3Kdelta/gamma inhibitors) that may improve upon the efficacy of anti-PD1 immunotherapy, both in advanced melanoma and in the adjuvant operable high-risk melanoma settings. He has advanced the multimodal therapy of melanoma with surgery, stereotactic radiotherapy, and molecular antitumor agents, displacing chemotherapy in the management of melanoma. He is now pioneering novel clinical trial designs to assess the myriad potential combinations of recently-approved molecular and immunological therapies that are anticipated to be the focus of translational clinical research trials in melanoma for the next decade.

His laboratory is engaged in the molecular and immunohistological analysis of tissues obtained from local institutional, regional, national, and international trials of new therapy. Tumor tissues from patients participating in new modalities and combination therapies, neoadjuvant trials, and prevention interventions are probed using current immunopathological and molecular assessments of signaling pathways, and immune responses to melanoma.

Summary

Marcus Malek, MD, director of Pediatric Surgical Oncology at UPMC Children’s Hospital of Pittsburgh, directs a unique research program focused on improving surgical outcomes in pediatric tumors through use of novel molecular imaging technology. Towards this end, he and his lab team are developing new surgical tracers to guide surgeons to the tumor, facilitate safe resection, and confirm that the entire tumor was removed.

Complete surgical resection of tumors is critical to providing the best possible patient outcomes, but unfortunately, incomplete resection is a common occurrence. A significant program being pursued by Dr. Malek and his team is a dual-labeled, tumor-specific tracer, that will provide both visual and audible signals within the tumor that can be detected using existing surgical tools. Although the project is specifically targeting pediatric neuroblastoma and osteosarcoma, ultimately the technology can also be applied to other types of pediatric tumors.

Summary

My broad research program will address the following question: How can the microbiome-specific immune response be modified or targeted to improve cancer patient response to immunotherapy? I will utilize the expertise and tools I have developed throughout my training to track and modify tumor- and microbiota-specific T cells in hopes of identifying current immunotherapeutic hurdles and developing targeting strategies for these unique cell populations. In addition, I will assess how previous therapies or other external changes to the gut microbiome impact response to immunotherapy in both mouse models and patient samples. Ultimately, I will define the interplay between the immune responses to the ever-changing gut microbiome during tumorigenesis. These studies have the potential to not only improve our understanding of resistance to immunotherapy in cancer, but also to identify novel means of enhancing anti-tumor responses through modulation of the microbiota or its products.

My previous work as a Damon Runyon postdoctoral fellow in the Hand lab focused on the study of bacteria-specific CD4+ T cells in colorectal cancer (CRC) after microbiome modulation with a single bacteria, Helicobacter hepaticus (Hhep). We found that bacteria-specific CD4+ T cells were sufficient to drive anti-tumor immunity and lead to an increase in organized tertiary lymphoid structures and tumor immune infiltration. Interestingly, tumor clearance was dependent on CD4+ T cells but not CD8+ T cells, the latter of which is the primary target population for most immunotherapies. These observations were published in Immunity (2021) and suggested for the first time that CD4+ T cells that are specific to the microbiome directly support the anti-tumor immune response and may represent a new therapeutic target in tumors that occur at barrier surfaces such as CRC. In addition, I have recently found that modulation of the colon microbiome through colonization with Hhep can have beneficial impacts on tumors located in distant barrier sites as well, such as the skin. I have combined a number of innovative tools and techniques with tumor lines that contain controlled and tunable neoantigens to track tumor- and bacteria-specific immune responses. I believe that these models will provide tremendous and unique tools that will aid my overarching research program of study.

Summary

My research focuses on understanding how immune cells integrate signals encountered in the environment to drive functional outcomes at the molecular and epigenetic level in both health and disease. The tumor microenvironment plays important roles in limiting T cell function and anti-tumor immunity. Our lab is exploring how the tumor microenvironment drives T cell dysfunction by altering the T cell epigenome and transcriptome. We use cutting-edge Next-generation sequencing technologies to interrogate the epigenome of T cells in murine models and patient samples. We aim to engineer the T cell epigenome to create better T cell therapies for cancer.

Summary

Our research program focuses on the mechanisms of cellular and molecular interactions in the tumor microenvironment. The elements of the tumor microenvironment can collectively exert both stimulatory and inhibitory pressures on the proliferative, angiogenic, neurogenic and immunomodulating potential of cancerous cells, as well as their ability to spread and metastasize. Thus, insights into the mechanisms regulating host responses to growing tumors are essential for assessing relative risks and improving the therapeutic index for novel therapies associated with the modulation of the tumor microenvironment. Tumor-mediated immune suppression and tolerance remains a key obstacle to the safe and efficacious induction of antitumor immunity by immunotherapeutic modalities. Tumor innervation by afferent and efferent branches of the Peripheral Nervous System and intratumoral neuronal and neuroglial elements are responsible for attraction and activation of immune regulatory cells and for direct regulation of malignant cell proliferation, spreading and metastasis. Cytokines, chemokines, and regulatory RNAs derived from the neuroglial cells play the major role in this phenomenon. Our long-term goal is to develop a feasible and effective therapeutic approach based on a combination of pharmacological inhibition of specific MRC pathways and recovery/boosting of tumor specific immune responses.

Summary

My laboratory studies tumor immunobiology and designs immunotherapies for the treatment of cancer based on results from translational modeling. My near-term research goal remains the development of novel phase I/II clinical trials for the treatment of patients with cancer, with a focus on melanoma and renal cell carcinoma (RCC). Such treatment modalities include dendritic cell (DC)-based vaccines, cytokine gene-modified DC injected directly into tumor lesions and combination treatment approaches integrating agents that modulate tumor cell immune recognition and/or alter the balance or Type-1 versus regulatory immunity in the tumor microenvironment (TME). We discovered that immune targeting of the tumor-associated vasculature occurs naturally during effective immunotherapy, and that vaccines targeting tumor blood vessel antigens (TBVA) can promote tumor regression, even in cases where cancer cells themselves cannot be directly recognized by protective/therapeutic CD8+ T cells. Notably, even though these vaccines target normal non-mutated peptide sequences in TBVA proteins, no untoward (auto)immune-related pathology was observed in translational mouse modeling. We determined that treatment with anti-angiogenic agents leads to tumor vascular normalization and to the improved chemokine-dependent recruitment of therapeutic T cells into the TME, resulting in local formation of tertiary lymphoid structures (TLS) in association with slowed tumor growth and extended survival in animal models. We recently completed a pilot phase II clinical trial (UPCI 12-048/NCT01876212) evaluating combined treatment of HLA-A2+ patients with autologous aDC1/TBVA peptide vaccines + dasatinib (employed as an immune adjuvant). Vaccines were well tolerated by patients and we observed objective clinical responses in 46% of evaluable patients with advanced-stage cutaneous or uveal melanoma, including 57% of patients with prior demonstration of primary resistance to anti-PD1-based immunotherapy. Novel DC/TBVA peptide vaccines are currently being investigated in pilot phase II studies supported by NIH R01 (NCT05127824) and P01 (NCT04093323) in the setting of checkpoint-refractory advanced melanoma and early-stage renal cell carcinoma. We are also currently investigating the use of IRF3 agonists (including STING agonists) delivered directly into the TME as components of in situ vaccines in the advanced disease setting with the intent to promote formation of TLS in situ for improved local cross-priming of novel therapeutic anti-tumor B cell and T cell repertoires.
