Abstract
BACKGROUND Knowledge of major histocompatibility complex (MHC) composition and distribution in rhesus macaque colonies is critical for management strategies that maximize the utility of this model for biomedical research. METHODS Variation within the Mamu-A and Mamu-B (class I) and DRB, DQA/B, and DPA/B (class II) regions of 379 animals from the Caribbean Primate Research Center's (CPRC) specific pathogen free (SPF) colony was examined using massively parallel sequencing. RESULTS Analyses of the 7 MHC loci revealed a background of Indian origin with high levels of variation despite past genetic bottlenecks. All loci exhibited mutual linkage disequilibria while conforming to Hardy-Weinberg expectations suggesting the achievement of mutation-selection balance. CONCLUSION The CPRC's SPF colony is a significant resource for research on AIDS and other infectious agents. Characterizing colony-wide MHC variability facilitates the breeding and selection of animals bearing desired haplotypes and increases the investigator's ability to understand the immune responses mounted by these animals.

Discovery of novel MHC-class I alleles and haplotypes in Filipino cynomolgus macaques (Macaca fascicularis) by pyrosequencing and Sanger sequencing: Mafa-class I polymorphism. Immunogenetics 2015; 67:563-78.

Abstract
Although the low polymorphism of the major histocompatibility complex (MHC) transplantation genes in the Filipino cynomolgus macaque (Macaca fascicularis) is expected to have important implications in the selection and breeding of animals for medical research, detailed polymorphism information is still lacking for many of the duplicated class I genes. To better elucidate the degree and types of MHC polymorphisms and haplotypes in the Filipino macaque population, we genotyped 127 unrelated animals by the Sanger sequencing method and high-resolution pyrosequencing and identified 112 different alleles, 28 at cynomolgus macaque MHC (Mafa)-A, 54 at Mafa-B, 12 at Mafa-I, 11 at Mafa-E, and seven at Mafa-F alleles, of which 56 were newly described. Of them, the newly discovered Mafa-A8*01:01 lineage allele had low nucleotide similarities (<86%) with primate MHC class I genes, and it was also conserved in the Vietnamese and Indonesian populations. In addition, haplotype estimations revealed 17 Mafa-A, 23 Mafa-B, and 12 Mafa-E haplotypes integrated with 84 Mafa-class I haplotypes and Mafa-F alleles. Of these, the two Mafa-class I haplotypes, F/A/E/B-Hp1 and F/A/E/B-Hp2, had the highest haplotype frequencies at 10.6 and 10.2%, respectively. This suggests that large scale genetic screening of the Filipino macaque population would identify these and other high-frequency Mafa-class I haplotypes that could be used as MHC control animals for the benefit of biomedical research.

Abstract
Pig-tailed macaques (Macaca nemestrina) serve as important models for human infectious disease research. Major histocompatibility complex (MHC) class II molecules are important to this research since they present peptides to CD4+ T cells. Despite the importance of characterizing the MHC-II alleles expressed in model species like pig-tailed macaques, to date, less than 150 MHC-II alleles have been named for the six most common classical class II loci (DRA, DRB, DQA, DQB, DPA, and DPB) in this population. Additionally, only a small percentage of these alleles are full-length, making it impossible to use the known sequence for reagent development. To address this, we developed a fast, high-throughput method to discover full-length MHC-II alleles and used it to characterize alleles in 32 pig-tailed macaques. By this method, we identified 128 total alleles across all six loci. We also performed an exon 2-based genotyping assay to validate the full-length sequencing results; this genotyping assay could be optimized for use in determining MHC-II allele frequencies in large cohorts of pig-tailed macaques.

Abstract
Major histocompatibility complex (MHC) gene products control the repertoire of T cell responses that an individual may create against pathogens and foreign tissues. This text will review the current understanding of MHC genetics in nonhuman primates, with a focus on Mauritian-origin cynomolgus macaques (Macaca fascicularis) and Indian-origin rhesus macaques (Macaca mulatta). These closely related macaque species provide important experimental models for studies of infectious disease pathogenesis, vaccine development, and transplantation research. Recent advances resulting from the application of several cost effective, high-throughput approaches, with deep sequencing technologies have revolutionized our ability to perform MHC genotyping of large macaque cohorts. Pyrosequencing of cDNA amplicons with a Roche/454 GS Junior instrument, provides excellent resolution of MHC class I allelic variants with semi-quantitative estimates of relative levels of transcript abundance. Introduction of the Illumina MiSeq platform significantly increased the sample throughput, since the sample loading workflow is considerably less labor intensive, and each instrument run yields approximately 100-fold more sequence data. Extension of these sequencing methods from cDNA to genomic DNA amplicons further streamlines the experimental workflow and opened opportunities for retrospective MHC genotyping of banked DNA samples. To facilitate the reporting of MHC genotypes, and comparisons between groups of macaques, this text also introduces an intuitive series of abbreviated rhesus MHC haplotype designations based on a major Mamu-A or Mamu-B transcript characteristic for ancestral allele combinations. The authors believe that the use of MHC-defined macaques promises to improve the reproducibility, and predictability of results from pre-clinical studies for translation to humans.

Abstract
The MHC class I-A and -B genes of cynomolgus macaques are highly polymorphic. These genes encode proteins presenting peptides to CD8+ T cells to initiate adaptive immune response. Recombination events are one way the diversity of these alleles can be increased. Such events have been well characterized in humans, but have not been as well characterized in macaques. In order to identify and examine recombinations that create new alleles, it is important to analyze intron sequences. Intron sequences have been shown to be important to understand the evolutionary mechanisms involved in the generation of major histocompatibility complex (MHC) alleles and loci. Thus far, there have been relatively few intron sequences reported for MHC class I alleles in macaques, and this has hampered the understanding of MHC organization and evolution in macaques. In this study, we present evidence of a gene conversion event generating the Mafa-B*099 allele lineage by the combination of Mafa-B*054 and Mafa-B*095 allele lineages. A potential recombination between the Mafa-A3*13 and Mafa-A4:14 lineages was also observed, but it is less clear due to lack of intron 2 sequence. This report stresses the role that recombination can play in MHC class I diversity in cynomologus macaques, and the importance of introns in identifying and analyzing such events.

Abstract
Nonhuman primate (NHP) models play a critical role in the translation of novel therapies for transplantation to the clinic. However, although MHC disparity significantly affects the outcome of transplantation, until recently, experiments using NHP models were performed without the ability to rigorously control the degree of MHC disparity in transplant cohorts. In this review, we discuss several key technical breakthroughs in the field, which have finally enabled detailed immunogenetic data to be incorporated into NHP transplantation studies. These advances have created a new gold-standard for NHP transplantation research, which incorporates detailed information regarding the degree of relatedness and the degree of MHC haplotype disparity between transplant pairs and the precise MHC alleles that both donors and recipients express. The adoption of this new standard promises to increase the rigor of NHP transplantation studies and to ensure that these experiments are optimally translatable to patient care.

Abstract
Here we describe the Immunogenetic Management Software (IMS) system, a novel web-based application that permits multiplexed analysis of complex immunogenetic traits that are necessary for the accurate planning and execution of experiments involving large animal models, including nonhuman primates. IMS is capable of housing complex pedigree relationships, microsatellite-based MHC typing data, as well as MHC pyrosequencing expression analysis of class I alleles. It includes a novel, automated MHC haplotype naming algorithm and has accomplished an innovative visualization protocol that allows users to view multiple familial and MHC haplotype relationships through a single, interactive graphical interface. Detailed DNA and RNA-based data can also be queried and analyzed in a highly accessible fashion, and flexible search capabilities allow experimental choices to be made based on multiple, individualized and expandable immunogenetic factors. This web application is implemented in Java, MySQL, Tomcat, and Apache, with supported browsers including Internet Explorer and Firefox on Windows and Safari on Mac OS. The software is freely available for distribution to noncommercial users by contacting Leslie.kean@emory.edu. A demonstration site for the software is available at http://typing.emory.edu/typing_demo , user name: imsdemo7@gmail.com and password: imsdemo.

Abstract
While HIV-1-specific cellular immunity is thought to be critical for the suppression of viral replication, the correlates of protection have not yet been determined. Rhesus macaques (RM) are an important animal model for the study and development of vaccines against HIV/AIDS. Our laboratory has helped to develop and study DNA-based vaccines in which recent technological advances, including genetic optimization and in vivo electroporation (EP), have helped to dramatically boost their immunogenicity. In this study, RMs were immunized with a DNA vaccine including individual plasmids encoding SIV gag, env, and pol alone, or in combination with a molecular adjuvant, plasmid DNA expressing the chemokine ligand 5 (RANTES), followed by EP. Along with standard immunological assays, flow-based activation analysis without ex vivo restimulation and high-throughput gene expression analysis was performed. Strong cellular immunity was induced by vaccination which was supported by all assays including PBMC microarray analysis that identified the up-regulation of 563 gene sequences including those involved in interferon signaling. Furthermore, 699 gene sequences were differentially regulated in these groups at peak viremia following SIVmac251 challenge. We observed that the RANTES-adjuvanted animals were significantly better at suppressing viral replication during chronic infection and exhibited a distinct pattern of gene expression which included immune cell-trafficking and cell cycle genes. Furthermore, a greater percentage of vaccine-induced central memory CD8+ T-cells capable of an activated phenotype were detected in these animals as measured by activation analysis. Thus, co-immunization with the RANTES molecular adjuvant followed by EP led to the generation of cellular immunity that was transcriptionally distinct and had a greater protective efficacy than its DNA alone counterpart. Furthermore, activation analysis and high-throughput gene expression data may provide better insight into mechanisms of viral control than may be observed using standard immunological assays.

Abstract
Pig-tailed macaques (Macaca nemestrina) provide important animal models in biomedical research, but utility of this species for HIV and other disease pathogenesis research is limited by incomplete knowledge of major histocompatibility complex (MHC) class I genetics. Here, we describe comprehensive MHC class I genotyping of 24 pig-tailed macaques, using pyrosequencing to evaluate a 367- bp complementary DNA (cDNA)-PCR amplicon spanning the highly polymorphic peptide-binding region of MHC class I transcripts. We detected 29 previously described Mane transcripts, 90 novel class I sequences, and eight shared MHC class IB haplotypes. We used this genotyping data to inform full-length MHC class I cDNA allele discovery, characterizing 66 novel full-length transcripts. These new full-length sequences nearly triple the number of Mane-B cDNA sequences previously characterized. The comprehensive genotypes and full-length Mane transcripts described herein add value to pig-tailed macaques as model organisms in biomedical research; furthermore, the coordinated method for MHC genotyping and allele discovery is extensible to other less well-characterized nonhuman primate species.
