van der Kuyl AC. Contemporary Distribution, Estimated Age, and Prehistoric Migrations of Old World Monkey Retroviruses. EPIDEMIOLGIA (BASEL, SWITZERLAND) 2021; 2:46-67. [PMID: 36417189 PMCID: PMC9620922 DOI: 10.3390/epidemiologia2010005] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 01/18/2021] [Accepted: 01/29/2021] [Indexed: 12/14/2022]
Abstract
Old World monkeys (OWM), simians inhabiting Africa and Asia, are currently affected by at least four infectious retroviruses, namely, simian foamy virus (SFV), simian immunodeficiency virus (SIV), simian T-lymphotropic virus (STLV), and simian type D retrovirus (SRV). OWM also show chromosomal evidence of having been infected in the past with four more retroviral species, baboon endogenous virus (BaEV), Papio cynocephalus endogenous virus (PcEV), simian endogenous retrovirus (SERV), and Rhesus endogenous retrovirus-K (RhERV-K/SERV-K1). For some of the viruses, transmission to other primates still occurs, resulting, for instance, in the HIV pandemic. Retroviruses are intimately connected with their host as they are normally spread by close contact. In this review, an attempt to reconstruct the distribution and history of OWM retroviruses will be made. A literature overview of the species infected by any of the eight retroviruses as well as an age estimation of the pathogens will be given. In addition, primate genomes from databases have been re-analyzed for the presence of endogenous retrovirus integrations. Results suggest that some of the oldest retroviruses, SERV and PcEV, have travelled with their hosts to Asia during the Miocene, when a higher global temperature allowed simian expansions. In contrast, younger viruses, such as SIV and SRV, probably due to the lack of a primate continuum between the continents in later times, have been restricted to Africa and Asia, respectively.

Am J Primatol 2018; 80:e22882.

Abstract
Simian retrovirus (SRV) is a type-D betaretrovirus infectious to the Old World monkeys causing a variety of symptoms. SRVs are also present in the Old World monkey genomes as endogenous forms, which are referred to as Simian endogenous retroviruses (SERVs). Although many SERV sequences have been identified in Cercopithecinae genomes, with potential of encoding all functional genes, the distribution of SERVs in genomes and evolutionary relationship between exogeneous SRVs and SERVs remains unclear. In this study, we comprehensively investigated seven draft genome sequences of the Old World monkeys, and identified a novel cluster of SERVs in the two Rhinopithecus (R. roxellana and R. bieti) genomes, which belong to the Colobinae subfamily. The Rhinopithecus genomes harbored higher copy numbers of SERVs than the Cercopithecinae genomes. A reconstructed phylogenetic tree showed that the Colobinae SERVs formed a distinct cluster from SRVs and Cercopithecinae SERVs, and more closely related to exogenous SRVs than Cercopithecinae SERVs. Three radical amino acid substitutions specific to Cercopithecinae SERVs, which potentially affect the infectious ability of SERVs, were also identified in the proviral envelope protein. In addition, we found many integration events of SERVs were genus- or species-specific, suggesting the recent activity of SERVs in the Old World monkey genomes. The results suggest that SERVs in Cercopithecinae and Colobinae monkeys were endogenized after the divergence of subfamilies and do not transmit across subfamilies. Our findings also support the hypothesis that Colobinae SERVs are direct ancestors of SRV-6, which has a different origin from the other exogenous SRVs. These findings shed novel insight into the evolutionary history of SERVs, and may help to understand the process of endogenization of SRVs.

Abstract
Simian betaretroviruses include the well-known exogenous simian retroviruses (SRV-1 through SRV-8), and some closely related simian endogenous retroviruses (SERV). Here, we characterized two new viral genomes, which appear to represent novel SERVs but have characteristics of both SRV and SERV highlighting the need to develop new assays providing molecular and serologic differentiation of SERV and SRV to avoid false positives.

Abstract
Due to recombination, different regions of a retrovirus genome can have distinct phylogenetic histories. The RD114-and-D-type-retrovirus (RDR) interference group provides an extreme example: the RDR group comprises a variety of taxonomically distinct retroviruses, isolated from diverse mammalian and avian hosts, that share a homologous env gene and use the same cell-surface entry receptor. RDR env homologs are also found among ancient endogenous retrovirus (ERV) sequences, including the syncytin genes of humans and rabbits, indicating that RDR Env glycoproteins have likely mediated endogenization on multiple occasions in diverse vertebrate lineages. The distribution of RDR env among exogenous and endogenous retroviruses indicates that it has been swapped between viruses many times, and that it likely facilitated multiple cross-species transmission events spanning millions of years of vertebrate evolution.

Abstract
This review is an updated summary of nearly 30 years of SRV history and provides new and critical findings of original research accomplished in the last 5 years including, but not limited to, the pathogenetic mechanisms underlying the origin of hematopoietic abnormalities observed in infected hosts and proposed new SRV serotypes. Despite major advances in the understanding and control of SRV disease, much more remains to be learned and SRV continues to be an exciting and attractive primate model for comparative studies of the mechanisms of retroviral immunosuppression.

Viral nucleic acids in live-attenuated vaccines: detection of minority variants and an adventitious virus. J Virol 2010; 84:6033-40.

Abstract
Metagenomics and a panmicrobial microarray were used to examine eight live-attenuated viral vaccines. Viral nucleic acids in trivalent oral poliovirus (OPV), rubella, measles, yellow fever, varicella-zoster, multivalent measles/mumps/rubella, and two rotavirus live vaccines were partially purified, randomly amplified, and pyrosequenced. Over half a million sequence reads were generated covering from 20 to 99% of the attenuated viral genomes at depths reaching up to 8,000 reads per nucleotides. Mutations and minority variants, relative to vaccine strains, not known to affect attenuation were detected in OPV, mumps virus, and varicella-zoster virus. The anticipated detection of endogenous retroviral sequences from the producer avian and primate cells was confirmed. Avian leukosis virus (ALV), previously shown to be noninfectious for humans, was present as RNA in viral particles, while simian retrovirus (SRV) was present as genetically defective DNA. Rotarix, an orally administered rotavirus vaccine, contained porcine circovirus-1 (PCV1), a highly prevalent nonpathogenic pig virus, which has not been shown to be infectious in humans. Hybridization of vaccine nucleic acids to a panmicrobial microarray confirmed the presence of endogenous retroviral and PCV1 nucleic acids. Deep sequencing and microarrays can therefore detect attenuated virus sequence changes, minority variants, and adventitious viruses and help maintain the current safety record of live-attenuated viral vaccines.

Abstract
Natural infection of feral Indian rhesus monkeys (Macaca mulatta) by a new simian beta retrovirus, provisionally called simian retrovirus-7 (SRV-7) is described. The virus is capable of in vitro replication in primary human peripheral blood lymphocytes (PBL) and B and T cell lines. We have earlier reported a novel SRV, SRV-6 from Indian langurs (Semnopithecus entellus). Additional sequence analyses from gp20 transmembrane (TM) env genes of SRV-6 and SRV-7 place them in a separate cluster, related to but distinct from known exogenous SRVs and also close to the simian endogenous beta retrovirus, (SERV) from African baboon. Phylogenetic analyses of pol gene of SRV-7 place it closer to SERV when the stop codons of the SERV genes are removed. On the other hand, additional sequence data from gp70, surface glycoprotein (SU) region of the env gene of SRV-6 suggest it is more closely related to known exogenous SRVs, (SRV-1 to 3). It is also related to the endogenous langur virus, Po-1-Lu. We hypothesize that SRV-6 and SRV-7 probably originated from a progenitor exogenous SRV which recombined with an endogenous SERV in the TM env and pol genes during evolution, based on the phylogenetic analyses.

Abstract
Amodel that explains both the origin and sporadic nature of cancer argues that cancer cells are a chance result of events that cause genomic and epigenetic variability. The prevailing view is that these events are mutations that affect chromosome segregation or stability. However, genomic and epigenetic variability is also triggered by cell fusion, which is often caused by viruses. Yet, cells fused by viruses are considered harmless because they die. We provide evidence that a primate virus uses both viral and exosomal proteins involved in cell fusion to produce transformed proliferating human cells. Although normal cells indeed fail to proliferate after fusion, expression of an oncogene or a mutated tumor suppressor p53 in just one of the fusion partners is sufficient to produce heterogeneous progeny. We also show that this virus can produce viable oncogenically transformed cells by fusing cells that are otherwise destined to die. Therefore, we argue that viruses can contribute to carcinogenesis by fusing cells.
