The California National Primate Research Center (CNPRC) is a federally funded biomedical research facility, dedicated to improving human and animal health, and located on the University of California, Davis, campus. The CNPRC is part of a network of seven National Primate Research Centers developed to breed, house, care for and study primates for medical and behavioral research. Opened in 1962, researchers at this secure facility have investigated many diseases, ranging from asthma and Alzheimer's disease to AIDS and other infectious diseases, and has also produced discoveries about autism. CNPRC currently houses about 4,700 monkeys, the majority of which are rhesus macaques, with a small population of South American titi monkeys. The center, located on 300 acres (1.2 km2) 2.5 miles west of the UC Davis campus, is sponsored by the National Institutes of Health (NIH).
