Hope APFED/AAAAI Pilot Grant Award Amount: $140,000 over a 2-year period, co-funded between APFED and AAAAI

Project: Stevens’ project entitled “The Role of Eosinophils in Aspirin Exacerbated Respiratory Disease Pathogenesis” is a novel and translational study that will help us to better understand what activates eosinophils and recruits them into tissues while also shedding light on their role in fibrin deposition that results in scarring of tissues. Aspirin Exacerbated Respiratory Disease (AERD) is used as a model for studying these processes further because of a very robust eosinophil response in this disease state.

Patient Impact: Findings from this study are expected to improve our understanding of eosinophil pathobiology and may help lead to the development of new diagnostic and therapeutic strategies for AERD and other eosinophil-associated disorders.

2012 HOPE Grant Recipients

APFED is proud to announce the recipients the 2012 HOPE Research Grants. The applications for this year were uniformly strong, making funding decisions difficult. After a thorough review process, APFED would like to congratulate Dr. Mei-Lun Wang (Children’s Hospital of Philadelphia) and Drs. Amir Kagalwalla (Children’s Memorial Hospital, Chicago, IL), Barry Wershil (Children’s Memorial Research Center, Chicago, IL), and Steven Ackerman (University of Illinois, Chicago) on receiving the HOPE faculty Grants. The HOPE Pilot Grant recipients are Dr. Lisa Spencer PhD (Department of Medicine, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA) and Dr. Kathryn Peterson MD (University of Utah, Salt Lake City, UT)

Dr. Wang’s research proposal is entitled “Esophageal Epithelial and Mesenchymal Cross-Talk in Eosinophilic Esophagitis”. Clinically, subepithelial fibrosis is an important feature of EoE, with mechanisms of this process poorly understood. Dr. Wang’s preliminary data suggest that fibroblasts can sense epithelial damage, and may prime profibrotic responses to epithelial food antigen exposure. Her research team will characterize epithelial-fibroblast interactions using culture systems in which the two cell types can be co-cultured within distances of microns. They will also test functional consequences of specific stimuli such as epithelial damage, acid/bile, and food antigens upon fibrogenesis using cell culture models using primary human esophageal epithelial cell lines. Dr. Wang’s research would greatly help elucidate the mechanisms of subepithelial fibrosis, and hopefully lead to therapies that would help prevent the clinical problems of dysphagia, esophageal strictures, and food impactions.

Drs. Kagalwalla’s, Wershil’s, and Ackerman’s research proposal seeks to “identify a panel of non-invasive biomarkers in the blood and/or urine of subjects with eosinophilic esophagitis (EoE) for the diagnosis and assessment of remission, recurrence or exacerbation of disease, as well as novel markers for responses to therapeutic intervention.” Their collaborative plan includes correlation of levels of inflammatory biomarkers (including mast cell, eosinophil, chemokine, interleukin, and growth factor biomarkers) from samples obtained from blood, urine, esophageal biopsies, and intraluminal esophageal string test. They propose to validate the non-invasive protein biomarker panel by measuring mRNA expression in esophageal biopsy samples. This research has the potential to fulfill the extremely important clinical need of finding a noninvasive and readily accessible method of assessing for the presence and activity of EoE, hopefully reducing the need for diagnostic endoscopies and biopsies in managing the disease.

Dr. Spencer’s proposal focuses on cytokine production by murine GI eosinophils, and tests the ability of GI eosinophils to behave as antigen-presenting cells. Per Dr. Spencer, her “work has probes the preformed cytokine potential of human blood eosinophils, the mechanisms by which eosinophils elaborate intracellular cytokines from preformed granular stores, and most recently, the role(s) of autocrine Notch signaling in eosinophil activation. This work has contributed to the growing body of data supporting nontraditional roles for eosinophils regulating both the immune microenvironment and tissue homeostasis”. Her intent is to “apply our broad expertise in the basic immunobiology of eosinophils to outstanding mechanistic questions in eosinophilic gastrointestinal diseases, thus establishing a new research avenue in the laboratory.” Her goals are to help to mechanistically define epidemiological correlations between allergic diseases (i.e. asthma) and GI disorders and suggest prophylactic approaches for early detection and treatment of patients. Dr. Spencer plans to generate data from the pilot grant to apply for additional funding.

Dr. Peterson’s proposal seeks to use an esophageal brush to detect MBP-1 in the esophagus “To determine the relationship between MBP-1 and fluorescence intensity and to determine the surface density of MBP-1 on cytology brush bristles as a function of the number of brushings colorimetric assays provide a rapid non-invasive approach to diagnose and monitor a wide variety of eosinophilic disorders.” Dr. Peterson intends to extend her assay to detect eosinophil involvement in eosinophilic gastroenteritis, eosinophilic asthma/Churg-Strauss, allergic sinusitis and eosinophilic cystitis. Her approach provides a less invasive path to monitor progress of each disease and response to therapy. Dr. Peterson plans to use data generated from this to obtain additional NIH funding to further develop the assay as a minimally invasive test to evaluate esophageal eosinophilia that can be performed at the bed side.

2011 HOPE Grant Recipients

Drs. Friedman and Spergel’s project involves the measurement of microRNAs (miRNA) in patients’ serum obtained via blood sample. miRNAs are short ribonucleic acid molecules that are important in regulating gene transcription and translation. Dr. Friedman’s research in Crohn’s disease has already shown distinct miRNA patterns in this patient population, and his proposed research aims to identify distinct miRNA expression patterns in patients with biopsy proven eosinophilic esophagitis (EoE) compared to patients with normal esophagus. His team hopes to correlate the miRNA expression to the severity of EoE on esophageal biopsy, thereby providing a noninvasive method of diagnosing and monitoring EoE disease activity through a simple blood test.

Drs. Ackerman and Furuta are collaborating on a project involving the esophageal string test (EST). The EST involves swallowing a small capsule with an attached string, with the process being minimally invasive compared to endoscopy and biopsy. The capsule can be swallowed with water or some pudding, while holding onto its attached string. The capsule breaks off in the intestine, and the end of the string dwells in the duodenum for a given period of time; then the string is removed and sent for analysis. The string directly samples esophageal secretions that contain potential EoE biomarkers from inflammatory cells. Their preliminary data have shown a nice correlation of EST sampling to EoE disease activity as determined by tissue biopsy. Funding for their project will help the researchers validate and improve the diagnostic accuracy of the EST and validate its use to monitor disease activity with treatment.

HOPE Grants are funded by donations to the HOPE on the Horizon Fund and by fundraisers hosted by families and friends of those living with eosinophil associated diseases.

APFED 2010 HOPE Junior Faculty Grant Recipient

Sophie Fillon, PhD Dr. Fillon University of Colorado Denver School of Medicine is working on research to determine the role of the microbiome in children with eosinophilic esophagitis (EoE). Dr. Fillon’s long-term goal is to become a leader in the field of EGIDS and to mentor a younger generation of students and post-doctoral fellows to enter into this nascent field. “This APFED HOPE award provides me with an outstanding opportunity to develop this line of research and would provide me with my first step in my junior faculty career.”

APFED 2009 HOPE Junior Faculty Grant Recipients

Antonella Cianferoni MD, PhD Dr. Cianferoni is an Assistant Professor of Pediatrics at the University Of Pennsylvania School Of Medicine and the Children’s Hospital of Philadelphia in the Division of Allergy and Immunology. Dr. Cianferoni’s research focus is identification of novel genes and biomarkers that will add to the understanding, treatment and management of eosinophilic gastrointestinal diseases. Dr. Cianferoni writes: “I am in the process of establishing a research program aimed to the understanding of the basic pathogenetic mechanisms of eosinophilic gastroeneteropathies. There is a great need to expand understanding and to identify novel pathogenetic mechanisms of EE and to identify biomarkers that will lead to better diagnostic tools and treatments of this still elusive disease.”

Carine Blanchard PhD Dr. Blanchard is a Postdoctoral fellow and research instructor at Cincinnati Children’s Hospital and Medical Center in the Division of Allergy and Immunology, focusing on the molecular pathogenesis of Eosinophilic Esophagitis and food allergy related disorders. Dr Blanchard writes: “My research will focus on mechanisms that induce eosinophilic disease, with the goal of ameliorating the pain and distress of eosinophilic esophagitis. If we truly uncover a major role for Uroplakin 1B in EE diagnosis, then this would lead to further studies aimed at trying to understand the fundamental basis of the disease pathology and pathogenesis.
