Interdisciplinary Research Groups
The ONPRC has Interdisciplinary Research Groups in the areas of Biology of Aging, Early Childhood Health and Development, and Primate Genetics to encourage and facilitate interdisciplinary research that is not within the scope of the primary scientific divisions, and to inform areas of future recruitment.
Biology of Aging
As human life expectancy continues to increase, there is a growing need for scientific knowledge about ways to promote healthy aging. The objective of the Biology of Aging (BoA) Program is to enhance our understanding of the mechanisms that underlie normal and pathological human aging, and to help with the development of effective therapies for age-associated diseases.
Key studies conducted by investigators at ONPRC have demonstrated age-related changes in several physiological systems in the rhesus macaque, paralleling those reported in humans. For example, they have found that female macaques, like humans, undergo menopause, and exhibit associated perturbation of circadian rhythms as well as declines in immune function and cognitive abilities. Ongoing studies are yielding clinically relevant discoveries, that are helping physicians to: 1) evaluate the therapeutic efficacy of various hormones for cognitive and emotional health in postmenopausal women; 2) determine how diet modulates age-related decline in immune function, circadian physiology, learning and memory; and 3) enhance vaccine efficacy and reduce morbidity and mortality following infection by delaying the aging of the immune system.
Such multi-disciplinary approacheds are made possible because of the world-class scientists and clinicians who make up the aging research consortium at OHSU. In addition, the maintenance of an aging rhesus macaque colony at ONPRC represents a major valuable resource. Nonhuman primate models provide several distinct advantages over rodents and have the potential to disclose important inter-related mechanisms that underlie human aging. This strength fosters the advancement of the basic, translational, and clinical research that is required to for treatment of age-associated diseases and for maintenance of life quality in the elderly.
The ONPRC BoA Program is an active component of the OHSU Healthy Aging Alliance.
EARLY CHILDHOOD HEALTH & DEVELOPMENT
The early childhood period is now being recognized as one of the most important developmental phases throughout one's lifespan. The intrauterine environment and gestational length and size at birth can have profound impact on an individual's development and mental and physical health throughout childhood as well as in adult life.The focus of the Early Childhood Health &Development (ECHD) Program is to bring together a diverse expertise of scientists at ONPRC, OHSU and beyond and to utilize non-human primate models which encompass key developmental stages known to strongly influence the risk of developing cardiovascular, pulmonary, metabolic and psychological disease during early childhood and throughout life. ECHD Program investigators collectively study events that occur during pregnancy (i.e., Bacterial and Viral infections such as Ureaplasma spp. and Zika virus, hypoxia, growth restriction, maternal nutrition, placental abnormalities and preterm birth), as well as broad aspects of human development (i.e., cardio-pulmonary physiology, neurodevelopment, immune function and vaccine development) as a means of understanding factors and/or events during prenatal and postnatal life that can have profound effect on the overall health of an individual.
The ONPRC is internationally recognized for its translational research in pregnancy and reproductive sciences and is one of the few primate centers in the United States that has the infrastructure and technical expertise to sustain an outstanding rhesus macaque time-mated breeding program (TMB). The TMB program is integral component of the animal resources provided to investigators by the ONPRC, in particular the ECHD Program. Based upon their biological similarities to humans, non-human primates are particularly useful for studies related to human parturition and developmental biology. In addition to the TMB program, the ONPRC has established an intensive care nursery specifically designed to support prematurely born rhesus macaques. The has enabling investigations to bridge the gap between maternal-fetal obstetrics and pediatric medicine.
The primary mission of the Primate Genetics Program (PGP) is to describe the relationship between genetic or epigenetic variation and common diseases in non-human primates, with the ultimate goal of advancing the treatment of human disease. The use of non-human primates capitalizes on the significant advantages of this model, including a high degree of genetic similarity with humans, extensive pedigreed populations that provide substantial analytical power, and a rigorously controlled environment (e.g. diet, housing), which enhances genetic signal over noise. We employ a variety of state-of-the-art approaches, including genomic, epigenomic and genetic methods, to study well established macaque models of disease. These include models of addiction, neurodegenerative disorders, cardiovascular disease, obesity, diabetes, macular degeneration, cancer, S/HIV resistance, demyelinating diseases, Batten's disease and age-associated diseases. Supporting these studies, we recently launched a large-scale genomic sequencing project, which will produce genome-wide data on 2,000 of the ONPRC pedigreed rhesus macaques over the next 3 years.
