Abstract
The distribution of the immune system throughout the body complicates in vitro assessments of coronavirus disease 2019 (COVID-19) immunobiology, often resulting in a lack of reproducibility when extrapolated to the whole organism. Consequently, developing animal models is imperative for a comprehensive understanding of the pathology and immunology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This review summarizes current progress related to COVID-19 animal models, including non-human primates (NHPs), mice, and hamsters, with a focus on their roles in exploring the mechanisms of immunopathology, immune protection, and long-term effects of SARS-CoV-2 infection, as well as their application in immunoprevention and immunotherapy of SARS-CoV-2 infection. Differences among these animal models and their specific applications are also highlighted, as no single model can fully encapsulate all aspects of COVID-19. To effectively address the challenges posed by COVID-19, it is essential to select appropriate animal models that can accurately replicate both fatal and non-fatal infections with varying courses and severities. Optimizing animal model libraries and associated research tools is key to resolving the global COVID-19 pandemic, serving as a robust resource for future emerging infectious diseases.

Abstract
Tripartite motif-containing protein 5α (TRIM5α) is generally known to block the postentry events of HIV-1. Here, we report an uncharacterized role for TRIM5α in the maintenance of viral latency. Knockdown of TRIM5α potentiates the transcription of HIV-1 in multiple latency models, which is reversed by shRNA-resistant TRIM5α. TRIM5α suppresses TNFα-activated HIV-1 LTR-driven as well as NF-κB- and Sp1-driven gene expression, with the RING and B-box 2 domains being the essential determinants. Mechanistically, TRIM5α binds to and enhances the recruitment of histone deacetylase 1 (HDAC1) to NF-κB p50 and Sp1. ChIP‒qPCR analyses further reveal that the association of TRIM5α with HIV-1 LTR induces HDAC1 recruitment and local H3K9 deacetylation. Conserved suppression effects of TRIM5α orthologs from multiple species on both HIV-1 and endo-retroelement HERV-K LTR activities have also been demonstrated. These findings provide new insights into the molecular mechanisms by which proviral latency is initially established and activatable proviruses are resilenced by histone deacetylase recruitment.

A Novel Vpu Adaptive Mutation of HIV-1 Degrades Tetherin in Northern Pig-Tailed Macaques (Macaca leonina) Mainly via the Ubiquitin-Proteasome Pathway and Increases Viral Release. J Virol 2023; 97:e0020023. [PMID: 36971578 PMCID: PMC10134834 DOI: 10.1128/jvi.00200-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 03/03/2023] [Indexed: 03/29/2023] Open
Abstract
Tetherin prevents viral cross-species transmission by inhibiting the release of multiple enveloped viruses from infected cells. With the evolution of simian immunodeficiency virus of chimpanzees (SIVcpz), a pandemic human immunodeficiency virus type 1 (HIV-1) precursor, its Vpu protein can antagonize human tetherin (hTetherin). Macaca leonina (northern pig-tailed macaque [NPM]) is susceptible to HIV-1, but host-specific restriction factors limit virus replication in vivo. In this study, we isolated the virus from NPMs infected with strain stHIV-1sv (with a macaque-adapted HIV-1 env gene from simian-human immunodeficiency virus SHIV-KB9, a vif gene replaced by SIVmac239, and other genes originating from HIV-1NL4.3) and found that a single acidic amino acid substitution (G53D) in Vpu could increase its ability to degrade the tetherin of macaques (mTetherin) mainly through the proteasome pathway, resulting in an enhanced release and resistance to interferon inhibition of the mutant stHIV-1sv strain, with no influence on the other functions of Vpu. IMPORTANCE HIV-1 has obvious host specificity, which has greatly hindered the construction of animal models and severely restricted the development of HIV-1 vaccines and drugs. To overcome this barrier, we attempted to isolate the virus from NPMs infected with stHIV-1sv, search for a strain with an adaptive mutation in NPMs, and develop a more appropriate nonhuman primate model of HIV-1. This is the first report identifying HIV-1 adaptations in NPMs. It suggests that while tetherin may limit HIV-1 cross-species transmission, the Vpu protein in HIV-1 can overcome this species barrier through adaptive mutation, increasing viral replication in the new host. This finding will be beneficial to building an appropriate animal model for HIV-1 infection and promoting the development of HIV-1 vaccines and drugs.

Abstract
Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is an emergent, amphixenotic infection that resulted in a pandemic declaration in March 2020. A rapid search for appropriate animal models of this newly emergent viral respiratory disease focused initially on traditional nonhuman primate research species. Nonhuman primate models have previously been shown to be valuable in evaluation of emerging respiratory coronaviruses with pandemic potential (ie, SARS-CoV and Middle East respiratory syndrome coronavirus). In this article, we review the pulmonary histopathologic characteristics and immunohistochemical evaluation of experimental SARS-CoV-2 infection in the rhesus macaque, pigtail macaque, African green monkey, and squirrel monkey. Our results indicate that all evaluated nonhuman primate species developed variably severe histopathologic changes typical of coronavirus respiratory disease characterized by interstitial pneumonia with or without syncytial cell formation, alveolar fibrin, and pulmonary edema that progressed to type II pneumocyte hyperplasia. Lesion distribution was multifocal, frequently subpleural, and often more severe in lower lung lobes. However, squirrel monkeys showed the least severe and least consistent lesions of the evaluated nonhuman primates. Additionally, our results highlight the disparate physical relationship between viral antigen and foci of pulmonary lesions. While classic respiratory coronaviral lesions were observed in the lungs of all nonhuman primates evaluated, none of the primates exhibited severe lesions or evidence of diffuse alveolar damage and therefore are unlikely to represent the severe form of SARS-CoV-2 infection observed in fatal human cases.

Abstract
The human-specific tropism of Human Immunodeficiency Virus Type 1 (HIV-1) has complicated the development of a macaque model of HIV-1 infection/AIDS that is suitable for preclinical evaluation of vaccines and novel treatment strategies. Several innate retroviral restriction factors, such as APOBEC3 family of proteins, TRIM5α, BST2, and SAMHD1, that prevent HIV-1 replication have been identified in macaque cells. Accessory proteins expressed by Simian Immunodeficiency virus (SIV) such as viral infectivity factor (Vif), viral protein X (Vpx), viral protein R (Vpr), and negative factor (Nef) have been shown to play key roles in overcoming these restriction factors in macaque cells. Thus, substituting HIV-1 accessory genes with those from SIV may enable HIV-1 replication in macaques. We and others have constructed macaque-tropic HIV-1 derivatives [also called simian-tropic HIV-1 (stHIV-1) or Human-Simian Immunodeficiency Virus (HSIV)] carrying SIV vif to overcome APOBEC3 family proteins. Additional modifications to HIV-1 gag in some of the macaque-tropic HIV-1 have also been done to overcome TRIM5α restriction in rhesus and cynomolgus macaques. Although these viruses replicate persistently in macaque species, they do not result in CD4 depletion. Thus, these studies suggest that additional blocks to HIV-1 replication exist in macaques that prevent high-level viral replication. Furthermore, serial animal-to-animal passaging of macaque-tropic HIV-1 in vivo has not resulted in pathogenic variants that cause AIDS in immunocompetent macaques. In this review, we discuss recent developments made toward developing macaque model of HIV-1 infection.

Abstract
APOBEC3 family members, particularly APOBEC3F and APOBEC3G, inhibit the replication and spread of various retroviruses by inducing hypermutation in newly synthesized viral DNA. Viral hypermutation by APOBEC3 is associated with viral evolution, viral transmission, and disease progression. In recent years, increasing attention has been paid to targeting APOBEC3G for AIDS therapy. Thus, a controllable model system using species such as macaques, which provide a relatively ideal in vivo system, is needed for the study of APOBEC3-related issues. To appropriately utilize this animal model for biomedical research, important differences between human and macaque APOBEC3s must be considered. In this study, we found that the ratio of APOBEC3G-mediated/APOBEC3-mediated HIV-1 hypermutation footprints was much lower in peripheral blood mononuclear cells (PBMCs) from northern pig-tailed macaques than in PBMCs from humans. Next, we identified a novel and conserved APOBEC3G pre-mRNA alternative splicing pattern in macaques, which differed from that in humans and resulted from an Alu element insertion into macaque APOBEC3G gene intron 1. This alternative splicing pattern generating an aberrant APOBEC3G mRNA isoform may significantly dilute full-length APOBEC3G and reduce APOBEC3G-mediated hypermutation pressure on HIV-1 in northern pig-tailed macaques, which was supported by the elimination of other possibilities accounting for this hypermutation difference between the two hosts.IMPORTANCE APOBEC3 family members, particularly APOBEC3F and APOBEC3G, are important cellular antiviral factors. Recently, more attention has been paid to targeting APOBEC3G for AIDS therapy. To appropriately utilize macaque animal models for the study of APOBEC3-related issues, it is important that the differences between human and macaque APOBEC3s are clarified. In this study, we identified a novel and conserved APOBEC3G pre-mRNA alternative splicing pattern in macaques, which differed from that in humans and which may reduce the APOBEC3G-mediated hypermutation pressure on HIV-1 in northern pig-tailed macaques (NPMs). Our work provides important information for the proper application of macaque animal models for APOBEC3-related issues in AIDS research and a better understanding of the biological functions of APOBEC3 proteins.

Abstract
Microbial translocation is a cause of systemic immune activation in HIV/SIV infection. In the present study, we found a lower CD8+ T cell activation level in Macaca leonina (northern pig-tailed macaques, NPMs) than in Macaca mulatta (Chinese rhesus macaques, ChRMs) during SIVmac239 infection. Furthermore, the levels of plasma LPS-binding protein and soluble CD14 in NPMs were lower than those in ChRMs. Compared with ChRMs, SIV-infected NPMs had lower Chiu scores, representing relatively normal intestinal mucosa. In addition, no obvious damage to the ileum or colon epithelial barrier was observed in either infected or uninfected NPMs, which differed to that found in ChRMs. Furthermore, no significant microbial translocation (Escherichia coli) was detected in the colon or ileum of infected or uninfected NPMs, which again differed to that observed in ChRMs. In conclusion, NPMs retained superior intestinal integrity and limited microbial translocation during SIV infection, which may contribute to their lower immune activation compared with ChRMs.

Abstract
The northern pig-tailed macaques (NPMs) lack TRIM5α, an antiviral restriction factor, and instead have TRIM5-CypA. In our previous study, we demonstrated that HIV-1NL4-3 successfully infected NPMs and formed a long-term viral reservoir in vivo. However, the HIV-1-infected NPMs showed relatively high viremia in the first 6 weeks of infection, which declined thereafter suggesting that HIV-1 NL4-3 infection in these animals was only partly permissive. To optimize HIV-1 infection in NPMs therefore, we generated HIV-1NL4-R3A and stHIV-1sv, and infected NPMs with these viruses. HIV-1NL4-R3A and stHIV-1sv can replicate persistently in NPMs during 41 weeks of acute infection stage. Compared to the HIV-1NL4-R3A, stHIV-1sv showed a notably higher level of replication, and the NPMs infected with the latter induced a more robust neutralizing antibody but a weaker cellular immune response. In addition, IFN-I signaling was significantly up-regulated with the viral replication, and was higher in the stHIV-1sv infected macaques. Consequently, the sequences of pro-viral env showed fewer G-A hyper-mutations in stHIV-1sv, suggesting that vif gene of SIV could antagonize the antiviral effects of APOBEC3 proteins in NPMs. Taken together, NPMs infected with HIV-1NL4-R3A and stHIV-1sv show distinct virological and immunological features. Furthermore, interferon-related gene expression might play a role in controlling primary HIV-1NL4-R3A and stHIV-1sv replication in NPMs. This result suggests NPM is a potential HIV/AIDS animal model.

Abstract
TRIMCyp generated by retrotransposition of a cyclophilin A inserting into TRIM5 locus, has been identified in owl monkey and most of Old World monkeys (OWM). Owl monkey TRIMCyp (omTRIMCyp) inhibits HIV-1 infection by direct interaction with viral capsid and indirect innate immune induction, whereas most of TRIMCyps from OWM cannot inhibit HIV-1, and the impact of which on immunoregulation is largely unknown. Here we reported that omTRIMCyp induces NF-κB, AP-1 and IFN-β activation in a dose-dependent manner, while TRIMCyp from northern pig-tailed macaque (npmTRIMCyp) does not activate NF-κB and moderately enhances AP-1 and IFN-β activities. The Cyclophilin A (CypA) domain plays an important role in omTRIMCyp-mediated NF-κB activation, and RBCC domains have a synergetic effect. We further indicated the mechanism by which npmTRIMCyp unable to activate NF-κB is that npmTRIMCyp hardly phosphorylates IκBα, different from omTRIMCyp which dramatically induces IκBα phosphorylation. Ubiquitination activity of omTRIMCyp was greater than npmTRIMCyp, although both could be ubiquitylated. Given that npmTRIMCyp neither interacts with viral capsid resulting in susceptibility to HIV-1 infection, nor activates NF-κB that is indispensable to HIV-1 provirus transcription, we proposed a model that npmTRIMCyp may play an important role in HIV-1 infected northern pig-tailed macaque with latency.

Association of TRIMCyp and TRIM5α from assam macaques leads to a functional trade-off between HIV-1 and N-MLV inhibition. SCIENCE CHINA-LIFE SCIENCES 2018; 61:954-965.

Abstract
TRIM5α restricts retroviruses in a species-specific manner. Cyclophilin A was independently retrotransposed into the TRIM5 loci in different species, leading to the generation of antiviral TRIM5-cyclophilin A (TRIMCyp) proteins. Previously, we found that assam macaques express a TRIMCyp chimera (amTRIMCyp), along with a TRIM5α allelic protein (amTRIM5α). Herein, we investigated the antiviral activity of amTRIMCyp and amTRIM5α individually, as well as their interaction and joint effects. amTRIMCyp showed a divergent restriction pattern from amTRIM5α. Although both proteins potently restricted the replication of HIV-1, only amTRIM5α inhibited N-MLV. Remarkably, cellular anti-HIV-1 activity increased when amTRIMCyp and amTRIM5α were coexpressed, indicating a synergistic block of HIV-1 replication. Consistently, PMBCs from heterozygous amTRIM5α/TRIMCyp showed stronger resistance to HIV-1 infection than those from amTRIM5α/TRIM5α homozygotes. The anti-HIV-1 synergistic effect was dependent on the amTRIMCyp-amTRIM5α interaction. In contrast, amTRIMCyp completely abrogated the anti-N-MLV activity mediated by amTRIM5α, showing a dominant-negative effect, indicating that the generation of amTRIMCyp was involved in the trade-off between divergent restriction activities. Our results provide a new paradigm to study functional trade-offs mediated by allelic proteins, a theoretical basis for utilizing animal models with various TRIM5 alleles, as well as novel HIV-1 gene therapy strategies.

Abstract
The northern pig-tailed macaque (Macaca leonina) has been identified as an independent species from the pig-tailed macaque group. The species is a promising animal model for HIV/AIDS pathogenesis and vaccine studies due to susceptibility to HIV-1. However, the major histocompatibility complex (MHC) genetics in northern pig-tailed macaques remains poorly understood. We have previously studied the MHC class I genes in northern pig-tailed macaques and identified 39 novel alleles. Here, we describe the MHC class II alleles in all six classical loci (DPA, DPB, DQA, DQB, DRA, and DRB) from northern pig-tailed macaques using a sequence-based typing method for the first time. A total of 60 MHC-II alleles were identified of which 27 were shared by other macaque species. Additionally, northern pig-tailed macaques expressed a single DRA and multiple DRB genes similar to the expression in humans and other macaque species. Polymorphism and positive selection were detected, and phylogenetic analysis suggested the presence of a common ancestor in human and northern pig-tailed macaque MHC class II allelic lineages at the DQA, DQB, and DRB loci. The characterization of full-length MHC class II alleles in this study significantly improves understanding of the immunogenetics of northern pig-tailed macaques and provides the groundwork for future animal model studies.

Abstract
Viral reservoirs of HIV-1 are a major obstacle for curing AIDS. The novel animal models that can be directly infected with HIV-1 will contribute to develop effective strategies for eradicating infections. Here, we inoculated 4 northern pig-tailed macaques (NPM) with the HIV-1 strain HIV-1NL4.3 and monitored the infection for approximately 3years (150weeks). The HIV-1-infected NPMs showed transient viremia for about 10weeks after infection. However, cell-associated proviral DNA and viral RNA persisted in the peripheral blood and lymphoid organs for about 3years. Moreover, replication-competent HIV-1 could be successfully recovered from peripheral blood mononuclear cells (PBMCs) during long-term infection. The numbers of resting CD4+ T cells in HIV-1 infected NPMs harboring proviruses fell within a range of 2- to 3-log10 per million cells, and these proviruses could be reactivated both ex vivo and in vivo in response to co-stimulation with the latency-reversing agents JQ1 and prostratin. Our results suggested that NPMs can be infected with HIV-1 and a long-term viral reservoir was formed in NPMs, which might serve asa potential model for HIV-1 reservoir research.

Abstract
The northern pig-tailed macaque (Macaca leonina) has been considered as an independent species from the pig-tailed macaque group. We have previously reported that this species macaque has the potential to be a useful animal model in HIV/AIDS pathogenesis and vaccine studies due to its susceptibility to HIV-1. To develop this animal into a potential HIV/AIDS model, we have studied the classical MHC genes of this animal. In this study, the non-classical MHC genes Malo-DM and Malo-DO alleles were first characterized by sequencing and cloning in 12 unrelated northern pig-tailed macaques. A total of 20 full-length sequences identified include 4 Malo-DMA, 5 Malo-DMB, 7 Malo-DOA, and 4 Malo-DOB alleles. Most of these allele sequences were shared between northern pig-tailed macaque and other macaque species in exon 2. The full-length MHC-DM and MHC-DO sequences provide more comprehensive analysis of immunogenetics of northern pig-tailed macaques and increase the value of the macaques in further biomedical studies.

Abstract
Northern pig-tailed macaques (NPMs, Macaca leonina) are susceptible to HIV-1 infection largely due to the loss of HIV-1-restricting factor TRIM5α. However, great impediments still exist in the persistent replication of HIV-1 in vivo, suggesting some viral restriction factors are reserved in this host. The APOBEC3 proteins have demonstrated a capacity to restrict HIV-1 replication, but their inhibitory effects in NPMs remain elusive. In this study, we cloned the NPM A3A-A3H genes, and determined by BLAST searching that their coding sequences (CDSs) showed 99% identity to the corresponding counterparts from rhesus and southern pig-tailed macaques. We further analyzed the anti-HIV-1 activities of the A3A-A3H genes, and found that A3G and A3F had the greatest anti-HIV-1 activity compared with that of other members. The results of this study indicate that A3G and A3F might play critical roles in limiting HIV-1 replication in NPMs in vivo. Furthermore, this research provides valuable information for the optimization of monkey models of HIV-1 infection.

Abstract
In the 20th century, thirteen distinct human immunodeficiency viruses emerged following independent cross-species transmission events involving simian immunodeficiency viruses (SIV) from African primates. In the late 1900s, pathogenic SIV strains also emerged in the United Sates among captive Asian macaque species following their unintentional infection with SIV from African sooty mangabeys (SIVsmm). Since their discovery in the 1980s, SIVs from rhesus macaques (SIVmac) and pig-tailed macaques (SIVmne) have become invaluable models for studying HIV pathogenesis, vaccine design and the emergence of viruses. SIV isolates from captive crab-eating macaques (SIVmfa) were initially described but lost prior to any detailed molecular and genetic characterization. In order to infer the origins of the lost SIVmfa lineage, we located archived material and colony records, recovered its genomic sequence by PCR, and assessed its phylogenetic relationship to other SIV strains. We conclude that SIVmfa is the product of two cross-species transmission events. The first was the established transmission of SIVsmm to rhesus macaques, which occurred at the California National Primate Research Center in the late 1960s and the virus later emerged as SIVmac. In a second event, SIVmac was transmitted to crab-eating macaques, likely at the Laboratory for Experimental Medicine and Surgery in Primates in the early 1970s, and it was later spread to the New England Primate Research Center colony in 1973 and eventually isolated in 1986. Our analysis suggests that SIVmac had already emerged by the early 1970s and had begun to diverge into distinct lineages. Furthermore, our findings suggest that pathogenic SIV strains may have been more widely distributed than previously appreciated, raising the possibility that additional isolates may await discovery.

Abstract
The complex and dynamic vaginal microbial ecosystem is critical to both health and disease of the host. Studies focusing on how vaginal microbiota influences HIV-1 infection may face limitations in selecting proper animal models. Given that northern pig-tailed macaques (Macaca leonina) are susceptible to HIV-1 infection, they may be an optimal animal model for elucidating the mechanisms by which vaginal microbiota contributes to resistance and susceptibility to HIV-1 infection. However, little is known about the composition and temporal variability of vaginal microbiota of the northern pig-tailed macaque. Here, we present a comprehensive catalog of the composition and temporal dynamics of vaginal microbiota of two healthy northern pig-tailed macaques over 19 weeks using 454-pyrosequencing of 16S rRNA genes. We found remarkably high proportions of a diverse array of anaerobic bacteria associated with bacterial vaginosis. Atopobium and Sneathia were dominant genera, and interestingly, we demonstrated the presence of Lactobacillus-dominated vaginal microbiota. Moreover, longitudinal analysis demonstrated that the temporal dynamics of the vaginal microbiota were considerably individualized. Finally, network analysis revealed that vaginal pH may influence the temporal dynamics of the vaginal microbiota, suggesting that inter-subject variability of vaginal bacterial communities could be mirrored in inter-subject variation in correlation profiles of species with each other and with vaginal pH over time. Our results suggest that the northern pig-tailed macaque could be an ideal animal model for prospective investigation of the mechanisms by which vaginal microbiota influence susceptibility and resistance to HIV-1 infection in the context of highly polymicrobial and Lactobacillus-dominated states.

Viral seroprevalence in northern pig-tailed macaques (Macaca leonina) derived from Ho Chi Minh City, Vietnam. Primates 2016; 57:413-9.

Abstract
Non-human primates are natural virus reservoirs, whether wild or domestic. In this study, we determined the seroprevalence of common viruses by ELISA in a northern pig-tailed macaque (Macaca leonina) colony derived from Ho Chi Minh City, Vietnam. A total of 20 types of virus which are commonly selected as target microorganisms for specific-pathogen-free colonies, or which have zoonotic potential were included in this study. The results showed only 2 in 90 northern pig-tailed macaques were seronegative for all the detected viruses, and at least 16 out of the total 20 types of virus tested were prevalent in this colony, so these macaques were commonly infected by various viruses. These macaques should be carefully assessed for viral seroprevalence in order to prevent zoonotic diseases from being transferred to human beings.

Abstract
The northern pig-tailed macaque (Macaca leonina) has been confirmed to be an independent species from the pig-tailed macaque group of Old World monkey. We have previously reported that the northern pig-tailed macaques were also susceptible to HIV-1. Here, to make this animal a potential HIV/AIDS model and to discover the mechanism of virus control, we attempted to assess the role of major histocompatibility complex (MHC) class I-restricted immune responses to HIV-1 infection, which was associated with viral replication and disease progression. As an initial step, we first cloned and characterized the classical MHC class I gene of northern pig-tailed macaques. In this study, we identified 39 MHC class I alleles including 17 MHC-A and 22 MHC-B alleles. Out of these identified alleles, 30 were novel and 9 were identical to alleles previously reported from other macaque species. The MHC-A and MHC-B loci were both duplicates as rhesus macaques and southern pig-tailed macaques. In addition, we also detected the patterns of positive selection in northern pig-tailed macaques and revealed the existence of balance selection with 20 positive selection sites in the peptide binding region. The analysis of B and F peptide binding pockets in northern and southern pig-tailed macaques and rhesus macaques suggested that they were likely to share a few common peptides to present. Thus, this study provides important MHC immunogenetics information and adds values to northern pig-tailed macaques as a promising HIV/AIDS model.

Abstract
As a non-human primate, the pig-tailed macaque has received wide attention because it can be infected by HIV-1. In this study, we determined the complete mtDNA sequence of the northern pig-tailed macaque (Macaca leonina). Unexpectedly, during the amplification of the mtDNA control region (D-loop region) we observed several D-loop-like sequences, which were NUMTs (nuclear mitochondrial sequences) and a total of 14 D-loop-like NUMT haplotypes were later identified in five individuals. The neighbor-joining tree and estimated divergence time based on these D-loop-like NUMT sequences of M. leonina provide some insights into the understanding of the evolutionary history of NUMTs. D-loop-like haplotypes G and H, which also exist in the nuclear genome of mulatta, appear to have been translocated into the nuclear genome before the divergence of M. mulatta and M. leonina. The other D-loop-like NUMT haplotypes were translocated into the nuclear genome of M. leonina after the divergence of the two species. Later sequence conversion was predicted to occur among these 14 D-loop-like NUMT haplotypes. The overall structure of the mtDNA of M. leonina was found to be similar to that seen in other mammalian mitochondrial genomes. Phylogenetic analysis based on the maximum likelihood method shows M. leonina clustered with Macaca silenus among the analyzed mammalian species.

Abstract
Pig-tailed macaques (Macaca nemistrina group) have been extensively used as non-human primate animal models for various human diseases in recent years, notably for AIDS research due to their sensitivity to HIV-1. Northern pig-tailed macaques (M. leonina) are distributed in China and other surrounding Southeast Asia countries. Although northern pig-tailed macaques have been bred on a large scale as experimental animals since 2012, the reference value of normal levels of leukocytes is not available. To obtain such information, 62 blood samples from male and female healthy northern pig-tailed macaques at different ages were collected. The normal range of major leukocyte subpopulations, such as T lymphocytes, B lymphocytes, natural killer (NK) cells, monocytes, and the expression levels of activation or differentiation related molecules (CD38, HLA-DR, CCR5, CD21, IgD, CD80 and CD86) on lymphocytes were analyzed by flow cytometry. The counts of B cells decreased with age, but those of CD8(+) T cells and NK cells and the frequency of CD38(+)HLA-DR(+)CD4(+) T cells were positively correlated with age. The counts of leukocyte subpopulations were higher in males than those in females except for CD4(+) T cells. Males also showed higher expression levels of IgD and CD21 within B cells. This study provides basic data about the leukocyte subpopulations of northern pig-tailed macaques and compares this species with commonly used Chinese rhesus macaques (M. mulatta), which is meaningful for the biomedical application of northern pig-tailed macaques.

Abstract
During the long-term evolutionary history, the interaction between virus and host has driven the first-line barrier, innate immunity, to invading pathogens. Innate immune factor TRIM5α and host peptidyl-prolyl cis-trans isomerase Cyclophilin A are two key players in the interaction between HIV-1 and host. Interestingly, Cyclophilin A is retrotransposed into the critical host gene, TRIM5, locus via LINE-1 element in some primate species including New World monkeys and Old World monkeys. This review aims to comprehensively discuss the sensing and immune activation procedures of TRIM5α innate signaling pathway through Cyclophilin A. It will then present the production of TRIMCyp chimeric gene and the different fusion patterns in primates. Finally, it will summarize the distinct restriction activity of TRIMCyp from different primates and explain the current understanding on the innate immune mechanisms involved in the early phase of the viral life cycle during HIV-1 replication.

Abstract
TRIMCyp is a fusion protein consisting of the TRIM5 gene product and retrotransposed Cyclophilin A (CypA). Two primate TRIMCyp fusion proteins with varying anti-HIV-1 activities independently evolved in owl monkeys and Old World monkeys. In addition, Old World monkey TRIMCyps lack exon7, which encodes amino acids in the Linker2 region. Previous studies on TRIM5α indicated that this region affects anti-retroviral activity, cytoplasmic body formation, and multimerization. The effects of exon7 deletion on the functions of the TRIMCyp are unclear. In this study, we found that the cytoplasmic bodies and multimers of owl monkey TRIMCyp (omTRIMCyp) are different from those of northern pig-tailed macaque TRIMCyp (npmTRIMCyp). In addition, we demonstrated that exon7 deletion affected cytoplasmic body formation and multimerization. Moreover, we unexpectedly found two chimeric proteins of omTRIMCyp and npmTRIMCyp that failed to block HIV-1 replication, despite the presence of CypA in omTRIMCyp. Further studies indicated that the cytoplasmic bodies and spontaneous multimerization were not responsible for TRIMCyp anti-HIV-1 activity. Moreover, potent viral restriction is associated with higher amounts of monomeric TRIMCyp when the CypA domain is able to recognize and bind to the HIV-1 capsid. Our results suggested that the deletion of exon7 during the evolution of TRIMCyp affected its function.

Abstract
Non-human primates (NHPs) are phylogenetically close to humans, with many similarities in terms of physiology, anatomy, immunology, as well as neurology, all of which make them excellent experimental models for biomedical research. Compared with developed countries in America and Europe, China has relatively rich primate resources and has continually aimed to develop NHPs resources. Currently, China is a leading producer and a major supplier of NHPs on the international market. However, there are some deficiencies in feeding and management that have hampered China's growth in NHP research and materials. Nonetheless, China has recently established a number of primate animal models for human diseases and achieved marked scientific progress on infectious diseases, cardiovascular diseases, endocrine diseases, reproductive diseases, neurological diseases, and ophthalmic diseases, etc. Advances in these fields via NHP models will undoubtedly further promote the development of China's life sciences and pharmaceutical industry, and enhance China's position as a leader in NHP research. This review covers the current status of NHPs in China and other areas, highlighting the latest developments in disease models using NHPs, as well as outlining basic problems and proposing effective countermeasures to better utilize NHP resources and further foster NHP research in China.

Abstract
The northern pig-tailed macaque (Macaca leonina) has been identified as an independent species of Old World monkey, and we previously found that PBMCs from M. leonina were susceptible to human immunodeficiency virus type 1 (HIV-1), which may be due to the absence of a TRIM5 protein restricting HIV-1 replication. Here we investigated the infection potentials of six laboratory adapted HIV-1 strains and three primary HIV-1 isolates in PBMCs from M. leonina. The results indicate that these strains are characterized by various but low replication levels, and among which, HIV-1NL4-3 shows the highest replication ability. Based on the abundant evidence of species-specific interactions between restriction factors APOBEC3 and HIV/SIV-derived Vif protein, we subsequently examined the replication potentials of vif-substituted HIV-1 (HSIV) in M. leonina PBMCs. Notably, HSIV-vifmac and stHIV-1SV chimeras, two HIV-1NL4-3-derived viruses encoding the viral infectivity factor (Vif) protein from SIVmac239, replicated robustly in cells from M. leonina, which suggests that HSIV could effectively antagonize the antiviral activity of APOBEC3 proteins expressed in cells of M. leonina. Therefore, our data demonstrate that M. leonina has the potential to be developed into a promising animal model for human AIDS.

Abstract
The origin of novel genes and their evolutionary fates are long-standing questions in evolutionary biology. These questions become more complicated for genes conserved across various lineages, such as TRIM5, an antiretroviral restriction factor and a retrovirus capsid sensor in immune signaling. TRIM5 has been subjected to numerous pathogenic challenges and undergone dynamic evolution, making it an excellent example for studying gene diversification. Previous studies among several species showed that TRIM5 gained genetic and functional novelty in a lineage-specific manner, either through gene duplication or a cyclophilin A retrotransposing into the TRIM5 locus, creating the gene fusion known as TRIM5-Cyclophilin A (TRIMCyp). To date, the general pattern of TRIM5 across the mammalian lineage remains elusive. In this study, we surveyed 36 mammalian genomes to verify a potentially novel TRIM5 pattern that uniquely seems to have occurred in tree shrews (Tupaia belangeri), and found that both gene duplication and retrotransposition worked jointly to form a specific TRIM5/TRIMCyp cluster not found among other mammals. Evolutionary analyses showed that tree shrew TRIMCyp (tsTRIMCyp) originated independently in comparison with previously reported TRIMCyps and underwent strong positive selection, whereas no signal of positive selection was detected for other tree shrew TRIM5 (tsTRIM5) genes. Functional assay results suggest a functional divergence between tsTRIMCyp and its closest paralog TRIM5-4, likely reflecting different fates under diverse evolutionary forces. These findings present a rare example of novel gene origination resulting from a combination of gene duplication, retrotransposition, and exon shuffling processes, providing a new paradigm to study genetic innovations and evolutionary fates of duplicated genes.

Abstract
Tibetan macaques (Macaca thibetana), stump-tailed macaques (M. arctoides), Assamese macaques (M. assamensis), and northern pig-tailed macaques (M. leonina) are four major species of Macaca in China. In order to effectively use these species in biomedical research, thorough investigations of their MHC immunogenetics are required. In this study, we identified MHC class I sequences using cDNA cloning and sequencing on a cohort of six M. thibetana, three M. arctoides, three M. assamensis, and three M. leonina derived from Sichuan and Yunnan provinces of China. Eighty new alleles were identified, including 26 MHC-A alleles, 46 MHC-B alleles, and 8 MHC-I alleles. Among them, Math-A1*126:01, Math-B*190:01, Math-B*191:01, Math-B*192:01, Maar-A1*127:01, Maar-A1*129:01, and Maas-A1*128:01 represent lineages that had not been reported earlier in Macaca. Phylogenetic analyses show that no obvious separation of lineages among these species of Macaca. This study provides important information about the MHC immunogenetics for the four major species of Chinese macaques and adds value to these species as model organisms in biomedical research.

Abstract
Increasing evidence indicates that the host range of primate lentiviruses is in part determined by their ability to counteract innate restriction factors that are effectors of the type 1 interferon (IFN-1) response. For human immunodeficiency virus type 1 (HIV-1), in vitro experiments have shown that its tropism may be narrow and limited to humans and chimpanzees because its replication in other non-human primate species is hindered by factors such as TRIM5α (tripartite motif 5 alpha), APOBEC3G (apolipoprotein B mRNA-editing, enzyme-catalytic, polypeptide-like 3), and tetherin. Based on these data, it has been hypothesized that primate lentiviruses will infect and replicate in a new species if they are able to counteract and evade suppression by the IFN-1 response. Several studies have tested whether engineering HIV-1 recombinants with minimal amounts of simian immunodeficiency virus sequences would enable replication in CD4+ T cells of non-natural hosts such as Asian macaques and proposed that infection of these macaque species could be used to study transmission and pathogenesis. Indeed, infection of macaques with these viruses revealed that Vif-mediated counteraction of APOBEC3G function is central to cross-species tropism but that other IFN-induced factors may also play important roles in controlling replication. Further studies of these macaque models of infection with HIV-1 derivatives could provide valuable insights into the interaction of lentiviruses and the innate immune response and how lentiviruses adapt and cause disease.

Abstract
Human immunodeficiency virus (HIV) has a very narrow host range. HIV type 1 (HIV-1) does not infect Old World monkeys, such as the rhesus monkey (Rh). Rh TRIM5α was identified as a factor that confers resistance, intrinsic immunity, to HIV-1 infection. Unfortunately, human TRIM5α is almost powerless to restrict HIV-1. However, human TRIM5α potently restricts N-tropic murine leukemia viruses (MLV) but not B-tropic MLV, indicating that human TRIM5α represents the restriction factor previously designated as Ref1. African green monkey TRIM5α represents another restriction factor previously designated as Lv1, which restricts both HIV-1 and simian immunodeficiency virus isolated from macaque (SIVmac) infection. TRIM5 is a member of the tripartite motif family containing RING, B-box2, and coiled-coil domains. The RING domain is frequently found in E3 ubiquitin ligase, and TRIM5α is thought to degrade viral core via ubiquitin–proteasome-dependent and -independent pathways. The alpha isoform of TRIM5 has an additional C-terminal PRYSPRY domain, which is a determinant of species-specific retrovirus restriction by TRIM5α. On the other hand, the target regions of viral capsid protein (CA) are scattered on the surface of core. A single amino acid difference in the surface-exposed loop between α-helices 6 and 7 (L6/7) of HIV type 2 (HIV-2) CA affects viral sensitivity to human TRIM5α and was also shown to be associated with viral load in West African HIV-2 patients, indicating that human TRIM5α is a critical modulator of HIV-2 replication in vivo. Interestingly, L6/7 of CA corresponds to the MLV determinant of sensitivity to mouse factor Fv1, which potently restricts N-tropic MLV. In addition, human genetic polymorphisms also affect antiviral activity of human TRIM5α. Recently, human TRIM5α was shown to activate signaling pathways that lead to activation of NF-κB and AP-1 by interacting with TAK1 complex. TRIM5α is thus involved in control of viral infection in multiple ways.

Abstract
TRIM5-cyclophilin A (TRIMCyp) fusion gene is an unusual TRIM5 locus. At present, this fusion phenomenon has been found in the representative species which contain owl monkey (Aotus trivirgatus) of Aotus genus that belongs to New World monkeys and Old World monkeys such as Northern pig-tailed macaque (M. leonina), Sunda pig-tailed macaque(M. nemestrina), Crab-eating macaque (M. fascicularis), Indian rhesus macaque (M. mulatta) and Assam macaque (M. assamensis), etc. But the fusion mode and transcription splicing pattern of TRIMCyp fusion gene are different between New World and Old World monkeys. The TRIMCyp fusion gene of New World monkeys is formed by inserting a CypA pseudogene cDNA sequence into the region between exon 7 and exon 8 of the TRIM5 locus through retrotransposition. However the TRIMCyp fusion gene of Old World monkeys results from the retrotransposition of a CypA pseudogene cDNA into 3' terminal or 3'-UTR of TRIM5 gene. The distributions, genotypes, expression and restricting activities against different retroviruses of TRIMCyp were different across species of primates. Moreover, most of the researches focused on the TRIMCyp fusion gene of owl monkey and pig-tailed macaque and found that they may play very important roles in restricting HIV-1 replication and determine the susceptibility to HIV-1 infection. It was reported that the TRIMCyp protein of owl monkey could inhibit HIV-1 infection in a similar way as TRIM5α, but TRIMCyp protein of pig-tailed monkey loss the restricting activity to HIV-1 infection. Here we reviewed the distributions, genotypes and restriction mechanism for inhibiting retroviruses replication of TRIMCyp fusion gene in primates.

Abstract
The retroviral restriction factor TRIMCyp, derived from the TRIM5 gene, blocks replication at a postentry step. TRIMCyp has so far been found in four species of Asian macaques, Macaca fascicularis, M. mulatta, M. nemestrina, and M. leonina. M. fascicularis is commonly used as a model for AIDS research, but TRIMCyp has not been analyzed in detail in this species. We analyzed the prevalence of TRIMCyp in samples from Indonesia, Indochina, the Philippines, and Mauritius. We found that TRIMCyp is present at a higher frequency in Indonesian than in Indochinese M. fascicularis macaques and is also present in samples from the Philippines. TRIMCyp is absent in Mauritian M. fascicularis macaques. We then analyzed the restriction specificity of TRIMCyp derived from three animals of Indonesian origin. One allele, like the prototypic TRIMCyp alleles described for M. mulatta and M. nemestrina, restricts human immunodeficiency virus type 2 (HIV-2) and feline immunodeficiency virus (FIV) but not HIV-1. The others restrict HIV-1 and FIV but not HIV-2. Mutagenesis studies confirmed that polymorphisms at amino acid residues 369 and 446 in TRIMCyp (or residues 66 and 143 in the cyclophilin A [CypA] domain) confer restriction specificity. Additionally, we identified a polymorphism in the coiled-coil domain that appears to affect TRIMCyp expression or stability. Taken together, these data show that M. fascicularis has the most diverse array of TRIM5 restriction factors described for any primate species to date. These findings are relevant to our understanding of the evolution of retroviral restriction factors and the use of M. fascicularis models in AIDS research.

Abstract
The retroviral restriction factor TRIMCyp, which is a fusion protein derived from the TRIM5 gene, blocks replication at a post-entry step. Among Old World primates, TRIMCyp has been found in four species of Asian macaques, but not in African monkeys. To further define the evolutionary origin of Old World TRIMCyp, we examined two species of baboons (genus Papio) and three additional macaque species, including M. sylvanus, which is the only macaque species found outside Asia, and represents the earliest diverging branch of the macaque lineage. None of four P. cynocephalus anubis, one P. hamadryas, and 36 M. sylvanus had either TRIMCyp mRNA or the genetic features required for its expression. M. sylvanus genomic sequences indicated that the lack of TRIMCyp in this species was not due to genetic homogeneity among specimens studied and revealed the existence of four TRIM5α alleles, all distinct from M. mulatta and Papio counterparts. Together with existing data on macaque evolution, our findings indicate that TRIMCyp evolved in the ancestors of Asian macaques approximately 5-6 million years before present (ybp), likely as a result of a retroviral threat. TRIMCyp then became fixed in the M. nemestrina lineage after it diverged from M. nigra, approximately 2 million ybp. The macaque lineage is unique among primates studied so far due to the presence and diversity of both TRIM5 and TRIMCyp restriction factors. Studies of these antiviral proteins may provide valuable information about natural antiviral mechanisms, and give further insight into the factors that shaped the evolution of macaque species.

Abstract
Human immunodeficiency virus type 1 (HIV-1) shows a very narrow host range limited to humans and chimpanzees. Experimentally, HIV-1 does not infect Old World monkeys, such as rhesus (Rh) and cynomolgus (CM) monkeys, and fails to replicate in activated CD4 positive T lymphocytes obtained from these monkeys. In contrast, simian immunodeficiency virus isolated from a macaque monkey (SIVmac) can replicate well in both Rh and CM. In 2004, tripartite motif 5 alpha (TRIM5 alpha) was identified as a host factor which plays an important role in the restricted host range of HIV-1. Rh and CM TRIM5 alpha restrict HIV-1 infection but not SIVmac, while in comparison, anti-viral activity of human TRIM5 alpha against those viruses is very weak. TRIM5 alpha consists of the RING, B-box 2, coiled-coil and SPRY (B30.2) domains. The RING domain is frequently found in E3 ubiquitin ligase and TRIM5 alpha is degraded via the ubiquitin-proteasome pathway during HIV-1 restriction. TRIM5 alpha recognises the multimerised capsid (viral core) of an incoming virus by its alpha-isoform specific SPRY domain and is believed to be involved in innate immunity to control retroviral infection. Differences in amino acid sequences in the SPRY domain of TRIM5 alpha of different monkey species were found to affect species-specific restriction of retrovirus infection, while differences in amino acid sequences in the viral capsid protein determine viral sensitivity to restriction. Accurate structural analysis of the binding surface between the viral capsid protein and TRIM5 alpha SPRY is thus required for the development of new antiretroviral drugs that enhance anti-HIV-1 activity of human TRIM5 alpha.

Abstract
As the HIV/AIDS pandemic continues unabated, novel prophylactic strategy for the spread of HIV are urgently needed. Topical microbicides are designed to prevent transmission of HIV when applied vaginally or rectally. Although there are many microbicide candidates in the pipeline, animal models for evaluating their safety and efficacy are urgently needed. On the basis of comparing the non-primate small animal models and the non-human primate animal models in evaluating safety and efficacy of HIV microbicides, this review summarizes the major advantages and disadvantages of the relevant animal models. The suggested direction of research that would benefit the development of microbicides is also reviewed.

Abstract
Background Human immunodeficiency virus type 1 (HIV-1) productively infects only humans and chimpanzees but not cynomolgus or rhesus monkeys while simian immunodeficiency virus isolated from macaque (SIVmac) readily establishes infection in those monkeys. Several HIV-1 and SIVmac chimeric viruses have been constructed in order to develop an animal model for HIV-1 infection. Construction of an HIV-1 derivative which contains sequences of a SIVmac239 loop between α-helices 4 and 5 (L4/5) of capsid protein (CA) and the entire SIVmac239 vif gene was previously reported. Although this chimeric virus could grow in cynomolgus monkey cells, it did so much more slowly than did SIVmac. It was also reported that intrinsic TRIM5α restricts the post-entry step of HIV-1 replication in rhesus and cynomolgus monkey cells, and we previously demonstrated that a single amino acid in a loop between α-helices 6 and 7 (L6/7) of HIV type 2 (HIV-2) CA determines the susceptibility of HIV-2 to cynomolgus monkey TRIM5α. Results In the study presented here, we replaced L6/7 of HIV-1 CA in addition to L4/5 and vif with the corresponding segments of SIVmac. The resultant HIV-1 derivatives showed enhanced replication capability in established T cell lines as well as in CD8+ cell-depleted primary peripheral blood mononuclear cells from cynomolgus monkey. Compared with the wild type HIV-1 particles, the viral particles produced from a chimeric HIV-1 genome with those two SIVmac loops were less able to saturate the intrinsic restriction in rhesus monkey cells. Conclusion We have succeeded in making the replication of simian-tropic HIV-1 in cynomolgus monkey cells more efficient by introducing into HIV-1 the L6/7 CA loop from SIVmac. It would be of interest to determine whether HIV-1 derivatives with SIVmac CA L4/5 and L6/7 can establish infection of cynomolgus monkeys in vivo.
