Oliver A. Garden, BVetMed, PhD, joined Penn Vet in 2016 as chair of the Department of Clinical Studies and Advanced Medicine. He was named as the Corinne R. and Henry Bower Professor of Medicine. Dr. Garden graduated from the Royal Veterinary College (1993) after earning his Bachelor of Science degree from King’s College London (1990). Following a rotating internship in small animal medicine and surgery, he completed a Wellcome Trust Clinical PhD program in small animal gastroenterology and immunology at the Royal Veterinary College (1998), followed by a Wellcome Trust Research training fellowship at the School of Medicine at the University of South Carolina. He held a residency in small animal internal medicine at Cornell University.His particular clinical interests include gastrointestinal and immune-mediated disease; Oliver has contributed chapters on immune-mediated disease and gastrointestinal immunology to two widely read textbooks in the field.

Oliver is the Principal Investigator of the Immune Regulation Laboratory . His particular clinical interests include gastrointestinal and immune-mediated disease. Oliver has contributed chapters on immune-mediated disease and gastrointestinal immunology to two widely read textbooks in the field. Oliver is also involved in the teaching and supervision of both interns and residents, at the Matthew J. Ryan Veterinary Companion Hospital , having contributed to the training of 43 interns and 58 residents over the years at his previous academic home, the Royal Veterinary College. He has lectured to veterinarians and veterinary nurses in the UK, USA and Asia – both general practitioners and specialists. Oliver has also been an invited speaker at the Penn Vet Annual Conference, the 2018 ACVP/ASVCP in Washington DC, 2018 ACVIM conference in Seattle, WA and he is the recipient of the 2017 Kennel Club International Canine Health Award.

Current Research in the Garden Laboratory focuses on the role of regulatory cells of lymphoid and myeloid origin in the pathogenesis of cancer and autoimmune disease. The laboratory is also interested in the role that Tregs and myeloid-derived suppressor cells (MDSCs) play in the development and progression of cancer in dogs. Dogs make excellent large animal models of various human cancers, recapitulating the human disease in a spontaneous manner that cannot be captured in genetically modified murine models.

IMMUNE REGULATION LABORATORY

Introduction

Professor Oliver Garden’s laboratory at the School of Veterinary Medicine at the University of Pennsylvania, Philadelphia, specialises in cellular immunology, with a specific expertise in regulatory T cell (Treg) and myeloid-derived suppressor cell (MDSC) biology. Oliver started his laboratory with the aid of a Wellcome Trust Advanced Fellowship in 2001 within the Department of Immunology, Imperial College London, Hammersmith Campus, following post-doctoral training at the University of South Carolina School of Medicine and a Residency in Small Animal Internal Medicine at Cornell University College of Veterinary Medicine.

Our People

Oliver Garden's team comprises clinical and research staff, including veterinarians, doctoral candidates, post-doctoral fellows, research assistants, interns, residents, and students. Current Staff includes Dr. Jie Luo, Ms. Julia Ying Wu, Ms. Sabina Hlavaty, as well as several undergraduate student workers. Alumni include Dr. Michelle Goulart, Mr. Michael Denyer, Dr. Dammy Pinheiro, Dr. James Swann, and Mr. Luca Fortuna. To date, six PhD students, five BSc students and 14 MSc students have successfully graduated following projects carried out within Oliver’s laboratory. Of the MSc students, ten gained Distinctions for their projects and all but two have completed – or are currently completing – successful PhD projects. Of the PhD students, all completed their theses within three or four years (depending on the program) and have carved out successful careers in research, medical practice or (in one case) patent law. Most recently, Sabina Hlavaty was awarded the Howard Hughes Medical Institute-Burroughs Wellcome Fund Medical Research Fellowship for 2018/2019.

Key expertise and funding

Key techniques for which Oliver’s laboratory has specific expertise include T cell culture, including sophisticated Treg assays in vitro; multi-colour analytical flow cytometry; ELISAs and enhanced electrochemiluminescent assays of a number of Th1 and Th2 cytokines; and molecular biological techniques, including PCR, cloning and transduction of constructs into mammalian cells.

Total extra-mural grant income since 2003 has been ˜ $2.2m, including industrial sources, the Medical Research Council, Mizutani Foundation for Glycoscience, Commonwealth Scholarship Commission, Biotechnology and Biological Research Council (BBSRC), European College of Veterinary Internal Medicine (ECVIM), Italian Ministry of Health, American College of Veterinary Emergency and Critical Care (ACVECC), Wellcome Trust, and Petplan Charitable Trust (PPCT). Current funding includes grants from the PPCT and various commercial sponsors.

Delivering for industry

Oliver’s laboratory has successfully worked with seven major industrial partners over the past ten years, consistently delivering on-time and within budget – for both product-orientated projects and blue-sky research. The laboratory has a dynamic, forward-looking, innovative and committed work ethic – with an unquestionable dedication to its team members, to its academic funders and to its industrial partners.

The biennial Treg/Th Cell Symposium

Oliver has been the coordinator for a biennial series of one-day symposia "Treg: Regulatory T Cells and T Helper Cells", the first one of which (March 2012) focused on ontogeny, plasticity and clinical applications. See the Proceedings notes for the first of these exciting events, published in Immunology. These meetings have been organised with the help of the RVC Continuing Professional Development Unit. Six world-class speakers came to the RVC to share their research findings in March of 2012, supported by three short oral communications and a number of poster presentations by PhD students and post-doctoral scientists.

The second of these exciting symposia was held at the RVC on 25th April 2014. Speakers included Professors Joachim Schultze, Awen Gallimore, Lucy Walker and Anne Cooke, and Drs Jeff Davies and Megan MacLeod. Please see "Treg: Regulatory T Cells and T Helper Cells" for details. Proceedings notes were published in Immunology, as well as a meeting review by Julia Wu in Immunology News.

Research awards

Two of Oliver's publications have been recognised by prestigious international awards:

(1) His review of systemic inflammatory response syndrome and sepsis, for which the first-named author is Dan Lewis, won an award for being one of the top five most downloaded publications in the Journal of Veterinary Internal Medicine in 2013, being downloaded a total of 6,372 times in this time period.

(2) His study of duodenal lesions in diet-responsive chronic enteropathy, for which the first-named author is David Walker, won a European Emesis Council / European Society of Comparative Gastroenterology award for the best gastrointestinal publication from a European research group in 2013.
