Abstract
Immunogenicity of biomolecules is one of the largest concerns in biological therapeutic drug development. Adverse immune responses as a result of immunogenicity to biotherapeutics range from mild hypersensitivity reactions to potentially life-threatening anaphylactic reactions and can negatively impact human health and drug efficacy. Numerous confounding patient-, product- or treatment-related factors can influence the development of an immune reaction against therapeutic proteins. The goal of this study was to investigate the relationship between pre-existing drug reactivity (PE-ADA), individual immunogenetics (MHC class II haplotypes), and development of treatment-induced antidrug antibodies (TE-ADA) in cynomolgus macaque. PE-ADA refers to the presence of antibodies immunoreactive against the biotherapeutic in treatment-naïve individuals. We observed that PE-ADA frequency against four different bispecific antibodies in naïve cynomolgus macaque is similar to that reported in humans. Additionally, we report a trend towards an increased incidence of TE-ADA development in macaques with high PE-ADA levels. In order to explore the relationship between MHC class II alleles and risk of ADA development, we obtained full-length MHC class II sequences from 60 cynomolgus macaques in our colony. We identified a total of 248 DR, DP, and DQ alleles and 236 unique haplotypes in our cohort indicating a genetically complex set of animals potentially reflective of the human population. Based on our observations, we propose the evaluation of the magnitude/frequency of pre-existing reactivity and consideration of MHC class II genetics as additional useful tools to understand the immunogenic potential of biotherapeutics.

Abstract
The MHC is a highly polymorphic genomic region that encodes the transplantation and immune regulatory molecules. It receives special attention for genetic investigation because of its important role in the regulation of innate and adaptive immune responses and its strong association with numerous infectious and/or autoimmune diseases. The MHC locus was first discovered in the mouse and for the past 50 years it has been studied most intensively in both mice and humans. However, in recent years the macaque species have emerged as some of the more important and advanced experimental animal models for biomedical research into MHC with important human immunodeficiency virus/simian immunodeficiency virus and transplantation studies undertaken in association with precise MHC genotyping and haplotyping methods using Sanger sequencing and next-generation sequencing. Here, in this special issue on 'Macaque Immunology' we provide a short review of the genomic similarities and differences among the human, macaque and mouse MHC class I and class II regions, with an emphasis on the association of the macaque class I region with MHC polymorphism, haplotype structure and function.

Abstract
Insulin-dependent diabetes mellitus is an autoimmune disease that causes a progressive destruction of the pancreatic beta cells. As a result, the patient requires exogenous insulin to maintain normal blood glucose levels. Both the pancreas and the islets of Langerhans have been transplanted successfully in humans and in animal models, resulting in full normalization of glucose homeostasis. However, insulin independence, transient or persistent, was documented in only a small fraction of cases until recently. The chronic immunosuppression required to avoid immunological rejection appears to be toxic to the islets and adds the risk of lymphoproliferative disease reported earlier. For islet transplantation to become the method of choice, it is essential first to identify islet-friendly immunosuppressive regimens and/or to develop methods that induce donor-specific tolerance and improve islet isolation and transplantation protocols. Indeed, researchers have already successfully allografted islets in the presence of nonsteroidal immunosuppression in a process known as the Edmonton protocol. An alternative method, gene therapy, could replace these other methods and better meet the insulin requirement of an individual without requiring pancreatic or islet transplantation. This alternative, however, requires animal models to develop and test clinical protocols and to demonstrate the feasibility of preclinical trials. Nonhuman primates are ideally suited to achieve these goals. The efforts toward developing a nonhuman primate diabetic model with demonstrable insulin dependence are discussed and include pancreatic and islet transplant trials to reverse the diabetic state and achieve insulin independence. Also described are the various protocols that have been tested in primates to circumvent immunosuppression by using tolerance induction strategies in lieu of immunosuppression, thus exploring the field of donor-specific tolerance that extends beyond islet transplantation.

Abstract
The macaque model of chlamydial pelvic inflammatory disease (PID) demonstrates individual variability in the time of onset of intrapelvic adhesions. Some animals develop adhesions rapidly, within 2 weeks after a single tubal inoculation with Chlamydia trachomatis, while in others, adhesions are not observed until 2 weeks after a second tubal inoculation. To test whether this variability correlates with major histocompatibility complex (MHC) class I haplotype, we used macaque alloantisera and mouse anti-HLA monoclonal antibodies to determine the MHC class I haplotypes of 44 C. trachomatis-infected macaques (Macaca nemestrina). Macaques developing gross tubal adhesions after the first chlamydial inoculation were classified as susceptible (n = 29), while those not developing adhesions until after the second chlamydial inoculation were classified as relatively resistant (n = 15), to adhesion formation. Three antibody specificities correlated with susceptibility (odds ratio [OR] 5.2, P < 0.01; OR 6.1 and 4.3, P < 0.05), and two correlated with relative resistance to adhesions (OR 0.1, P < 0.05; OR 0.2, P < 0.01). Because several of these antibodies are cross-reactive, as many as five different MHC class I alleles (three increasing and two decreasing ORs) or as few as two different MHC class I alleles (one increasing and one decreasing OR) could be correlated with risk of adhesion formation. We conclude that in macaques, susceptibility or relative resistance to rapid formation of tubal adhesions is correlated with expression of MHC class I alleles, consistent with reports of MHC class I restriction of chlamydial immunopathology in humans.

Abstract
The second exon of primate MHC-DRB genes encodes discrete areas of allelic hypervariability (HVR), which are used as the basis for lineage assignments to determine genetic and evolutionary relationships. Comparisons of these regions have led to the "trans-species hypothesis", which proposes that certain MHC alleles from one species are more closely related to those from other species than they are to each other; i.e., that allelic lineages are ancestral in origin. We evaluated this paradigm in an analysis of macaque and baboon MHC-DRB genes using oligotyping and sequencing of 87 new nonhuman primate DRB alleles. A remarkable conservation of sequence motifs in the HVRIII region (codon 60-79) was observed, detected both by hybridization and by sequencing; some of these motifs were found in species such as prosimians that have diverged from the human lineage 50 MYA. However, these fixed HVRIII motif sequences nevertheless occur on a background of diverse lineages suggesting that it is the segmental motif, rather than the allele per se which is trans-specific in origin. Sequences within the first hypervariable region (codons 7-14) identified lineage assignments to several DRB loci (DRB1, DRB3, DRB4, DRB5, DRB6 and DRB7), although a large number of DRB nucleotide sequences did not correspond to a defined allelic motif, suggesting that many of the nonhuman sequences lack human HVRI homologs and have accumulated additional intraspecies variation subsequent to speciation. While there are certain allelic lineages in HVRI that show trans-species conservation, other sequence motifs seem purely species-specific. These differences suggest that HVRI and HVRIII regions have distinct mechanisms for maintenance of trans-specific sequence elements, with different evolutionary histories for segmental nucleotide conservation.

Abstract
To obtain a better estimate of major histocompatibility complex (MHC) polymorphism in the Old World macaque, Macaca fascicularis, class I and class II MHC proteins from 42 animals were analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and one-dimensional isoelectric focusing (1D-IEF). The panel represented both related and unrelated animals with a total of at least 30 serologically distinct haplotypes. Cells were sequentially immunoprecipitated with monoclonal antibody (mAb) W6/32 for class I and with mAb L243 for class II molecules, followed by neuraminidase treatment. Both sets of immunoprecipitates yielded 5-7 major bands on IEF. All bands present in offspring were present in at least 1 parent. Siblings which were serologically identical for class I and which were non-stimulatory in mixed lymphocyte culture (MLC) yielded identical IEF patterns for both class I and class II; in other sibling pairs which were serologically identical for class I antigens (Ag), IEF produced convincing evidence that the siblings were indeed nonidentical, or helped to verify that recombination had occurred within the MHC. Specific bands were found which correlated with class I specificities A8, A24, and B25 previously defined by serology. Comparison of serological and biochemical data will broaden our understanding of the MHC in Macaca fascicularis and will increase the potential use of this species in transplantation research, as a model of disease, and for comparative studies.

Abstract
The inhibitory effect of anti-HLA class I monoclonal antibodies on lymphocyte proliferation has been well documented. However, recent data suggest that anti-HLA class I monoclonal antibodies can enhance lymphocyte proliferation via both anti-CD3-induced (1,2) and anti-CD2-induced (3) activation pathways. Here we demonstrate that both inhibition and activation can be regulated by the degree of aggregation of HLA class I antigens. Crosslinking of monoclonal antibodies specific for HLA-A, HLA-B, or monomorphic determinants (using anti-IgG2 and/or anti-Ig kappa "second step" monoclonal antibodies) increased the capacity of anti-HLA class I monoclonal antibodies to inhibit phytohemagglutinin-induced proliferation. However, the cytosolic free calcium concentration was increased in CD4+ cells, CD8+ cells, B cells, and CD16+ cells when anti-HLA class I monoclonal antibodies were crosslinked, suggesting that an activation signal was generated by aggregation of the corresponding antigens. Indeed, inositol 1,4,5-trisphosphate could be detected in peripheral blood lymphocytes following crosslinking of anti-HLA class I monoclonal antibodies. Class I aggregation also induced proliferation of peripheral blood mononuclear cells in the presence of submitogenic doses of phorbol 12-myristate 13-acetate. Strong conditions of crosslinking (monomorphic monoclonal antibody plus both anti-IgG2 and anti-Ig kappa) induced CD25 expression and responsiveness to recombinant interleukin 2. Our results suggest that aggregation of HLA class I antigens primed cells to become activated in the presence of progression signals including phorbol 12-myristate 13-acetate, recombinant interleukin 2, or anti-CD5 plus anti-CD28 monoclonal antibodies.

Abstract
The major histocompatibility complex (MHC) of pigtailed macaques (Macaca nemestrina, Mn) is defined and designated as MnLA. Twenty-nine alloantisera were generated by fullsib alloimmunization and tested against a panel of 220 unrelated animals. The reactivities of different alloantisera were analyzed statistically in pairwise comparisons. Using 2 X 2 contingency tables, we calculated chi 2 independence, chi 2 allelism, and correlation coefficient values. Initially, specificities were defined by significant associations of certain sera, but some sera defined specificities individually. In all, 15 specificities were defined, and by family studies and negative correlation coefficients, a two-locus model was evident. Genetic analyses, together with statistical applications, revealed that the behavior of these specificities is consistent with the nature of MHC in other primate species, including man.
