Nonhuman primate (NHP) biomedical models are critical to our understanding of human health and disease, yet we are still in the early stages of developing sufficient tools to support primate genomic research that allow us to better understand the basis of phenotypic traits in NHP models of disease. A mere 7 years ago, the limited NHP transcriptome profiling that was being performed was done using complementary DNA arrays based on human genome sequences, and the lack of NHP genomic information and immunologic reagents precluded the use of NHPs in functional genomic studies. Since then, significant strides have been made in developing genomics capabilities for NHP research, from the rhesus macaque genome sequencing project to the construction of the first macaque-specific high-density oligonucleotide microarray, paving the way for further resource development and additional primate sequencing projects. Complete published draft genome sequences are now available for the chimpanzee ( Chimpanzee Sequencing Analysis Consortium 2005), bonobo ( Prufer et al. 2012), gorilla ( Scally et al. 2012), and baboon ( Ensembl.org 2013), along with the recently completed draft genomes for the cynomolgus macaque and Chinese rhesus macaque. Against this backdrop of both expanding sequence data and the early application of sequence-derived DNA microarrays tools, we will contextualize the development of these community resources and their application to infectious disease research through a literature review of NHP models of acquired immune deficiency syndrome and models of respiratory virus infection. In particular, we will review the use of -omics approaches in studies of simian immunodeficiency virus and respiratory virus pathogenesis and vaccine development, emphasizing the acute and innate responses and the relationship of these to the course of disease and to the evolution of adaptive immunity.
