Four m sections were cut and stained with haematoxylin and eosin (H&E) and examined microscopically. conceived the study. We demonstrate the high level (>85%) of conservation of rhesus monkey stemness gene expression across five different rhesus monkey embryonic stem cell lines (ORMES 6, 7, 9, 10 . [29] The gene codes for the RhD protein on the red blood cell membrane. In Africans, there are three molecular backgrounds that give rise to the Rh D-phenotype which is found in 8% of the population. The term "Rhesus antigen" was introduced by Landsteiner and Wiener, who found that rabbits (and later, guinea pigs) immunized with red blood cells (RBCs) from a rhesus monkey produced antibodies which agglutinated 85% of Caucasian blood samples (Landsteiner and Wiener 1940, 1941). Based on different models of genetic inheritance, two different terminologies were developed; both of them are still in use. Furthermore, there was an increased prominence of bronchial-associated lymphoid tissue (BALT) was noted. [citation needed], For a long time, the origin of RHD polymorphism was an evolutionary enigma. [19] The frequency of Rh factor blood types and the RhD neg allele gene differs in various populations. 212, 459462 (2020). Cell Mol. In the bronchi and bronchioles, similar changes to those described for cynomolgus macaques were seen (Fig. Virus shedding from the gastrointestinal tract was assessed by RT-qPCR performed on rectal swab samples. These include genes involved in hair formation, immune response, membrane proteins and sperm-egg fusion. ", "Blood Type Frequencies by Country including the Rh Factor Rhesus Negative", "Re: Is the RH negative blood type more prevalent in certain ethnic groups? Animals were housed in compatible social groups, in cages in accordance with the UK Home Office Code of Practice for the Housing and Care of Animals Bred, Supplied or Used for Scientific Procedures (2014) and National Committee for Refinement, Reduction and Replacement (NC3Rs) Guidelines on Primate Accommodation, Care and Use, August 200645. 2A ). To obtain rhesus monkey gene in caucasian. Representative images from 6 slides per animal at each time point. 6e). The frequency with which self-identified white participants had African ancestry varied significantly by region. mn CD107a expression in CD8+ and T-cells in PBMCs. Mais, DD. To view a copy of this license, visit http://creativecommons.org/licenses/by/4.0/. Population genetics scientists from institutions including Harvard University analyzed DNA from thousands of Americans who described themselves as being part of a singular racial group. Whole blood and serum were collected at the same time points. Lewandowski, K. et al. The left lung was dissected prior to BAL collection and used for subsequent histopathology and virology procedures. In serologic testing, D positive blood is easily identified. These features have been of particular value in HIV vaccine research where models are established in both rhesus macaques (Indian genotype) and cynomolgus macaques (Mauritian genotype)44. After 48 hours of birth, the newborn may be allowed to nurse from its mother as her antibodies can no longer be absorbed through the neonates intestines. There was some evidence of potential sex differences, although the n number maybe too low to draw specific conclusions (Supplementary Fig. Immunol. Enlarged liver, spleen, or heart and fluid buildup in the fetus' abdomen seen via ultrasound. It's descended from a molecule called Amt. March 14, 2023 . 58, e0096300919 (2019). Intracellular cytokine staining (ICS) and immunophenotyping assays were performed using 1 106 PBMC or MNC in R10 medium (described above). [18], According to a comprehensive study, the worldwide frequency of Rh-positive and Rh-negative blood types is approximately 94% and 6%, respectively. Analysis of the monkey's DNA sequence has also deepened a few mysteries in our understanding of the biology of primates when it comes to vital parts of our biology, such as the X chromosome. Other animals have entirely different blood groups. Skinner, J. M. et al. Other primate genomes underway include the marmoset, gibbon and gorilla. "This study of the rhesus genome is invaluable because it gives researchers a perspective to observe what has been added or deleted in each primate genome during evolution of rhesus, chimp, and the human from their common ancestors," said Richard Gibbs, Ph.D., director of Baylor College of Medicine's Human Genome Sequencing Center in Houston and the project leader. Positive samples were restricted to early timepoints post-infection-challenge, which suggests some level of new virus replication which is also supported by the level of virus detected using RNA probes conducted on samples collected from animals euthanised 4/5 dpc13. 9l). It will also be applicable to assessing the efficacy of therapeutics in these NHP COVID-19 models. This is of particular importance to D negative females at or below childbearing age, because any subsequent pregnancy may be affected by the Rh D hemolytic disease of the newborn if the baby is D positive. Interrogation of IFN- spot forming units (SFU) measured in response to stimulation with overlapping 15-mer spike protein-peptide pools indicated that peptides spanning the breadth of the SARS-CoV-2 spike protein sequence induced cellular immune responses in infected cynomolgus macaques; whereas, peptide pool (PP) sequences 2-4 and 8 were most immunogenic in rhesus macaques (Fig. A lung histopathology scoring system was setup and used to evaluate the severity of the histopathological lesions observed in each animal (Table1), including lesions affecting the airways and the parenchyma. Antibodies to Rh antigens can be involved in hemolytic transfusion reactions and antibodies to the Rh(D) and Rh antigens confer significant risk of hemolytic disease of the fetus and newborn. The BCM-HGSC has sequenced the genome of the rhesus monkey (rhesus macaque, Macaca mulatta). The allele was thus often assumed in early blood group analyses to have been typical of populations on the continent; particularly in areas below the Sahara. PBMC samples were isolated from uninfected animals (nave) or at early (days 4 and 5) and late (days 14-19) time-points following SARS-CoV-2 infection. 6, eaba8399 (2020). Vabret, N. et al. Huang, C. et al. Comparison of CD4+ and CD8+ T-cell frequencies indicated that the proportion of CD8+ T-cells was greater in cynomolgus macaques prior to, and also after infection when the frequency of the CD4+ subset increased but remained secondary to the CD8+ population in peripheral blood and lung MNC (Fig. By comparison, humans and chimpanzees share about 98 to 99 percent of their DNA. Other important findings of the overall study include extensive sub-microscopic chromosome changes that have occurred relative to humans and chimpanzees. But since they dont have red blood cells, they cannot have Rhesus blood type! Subgenomic RNA was also detected in the nasal cavity of cynomolgus macaques at four and 5 dpc. the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in Rh and Amt dont just share DNA sequence: they also have similar jobs! Publishers note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. 9a, b). Its the + or - in A+, B-, O+, etc. Additionally, in a comparative study of colonisation of NHPs by group A Steptococcus pyogenes it was reported that cynomolgus developed a stronger antibody response compared to rhesus macaques42, a trend that we also observed. The testing is difficult, since using different anti-D reagents, especially the older polyclonal reagents, may give different results. Immune responses against SARS-CoV-2 are also similar in both species and equivalent to those reported in milder infections and convalescent human patients. The Rh blood group system consists of 49 defined blood group antigens,[1] among which the five antigens D, C, c, E, and e are the most important. Both macaque models potentially represent the majority of the human population and enable evaluation of the safety and efficacy of novel and repurposed interventions against SARS-CoV-2 using endpoints of upper and lower respiratory tract virus replication, in addition to CT and histopathology in the assessment of significant but transient lung injury. Specific antibodies against SARS-CoV-2 were detected in serum collected from both rhesus and cynomolgus macaques from 8 to 9 dpc onwards (Fig. The three megapools were made up as such: Megapool 1 (MP1) comprised peptide pools 1-3, Megapool 2 (MP2) comprised peptide pools 4-6 and Megapool 3 (MP3) comprised of peptide pools 7-10. CT imaging was performed on sedated animals using a 16 slice Lightspeed CT scanner (General Electric Healthcare, Milwaukee, WI, USA) in the prone and supine position to assist the differentiation of pulmonary changes at the lung bases caused by gravity dependant atelectasis, from ground glass opacity caused by SARS-CoV-2. Whole-genome sequencing was performed, on the P3 challenge stock, using both Nanopore and Illumina as described previously47. An IFN ELISpot assay was used to estimate the frequency and IFN production capacity of SARS-CoV-2-specific T-cells in PBMCs using a human/simian IFN kit (MabTech, Nacka. "The sequencing of the rhesus macaque genome, combined with the availability of the chimp and human genomes, provides researchers with another powerful tool to advance our understanding of human biology in health and disease," said NHGRI Director Francis S. Collins, M.D., Ph.D. "As we build upon the foundation laid by the Human Genome Project, it has become clear that comparing our genome with the genomes of other organisms is crucial to identifying what makes the human genome unique.". Immun. In these areas, alveolar spaces were often obliterated by collapse of the thickened and damaged alveolar walls which contained mixed inflammatory cells (Fig. During the 1950s, they were the laboratory animal models used to investigate, develop, and produce the polio vaccine ( Johnsen, 1995 ). 2).

This real factor found in rhesus macaque was classified in the Landsteiner-Weiner antigen system (antigen LW, antibody anti-LW) in honor of the discoverers.[53][54]. All experimental work was conducted under the authority of a UK Home Office approved project license (PDC57C033) that had been subject to local ethical review at PHE Porton Down by the Animal Welfare and Ethical Review Body (AWERB) and approved as required by the Home Office Animals (Scientific Procedures) Act 1986. Weak D phenotype can occur in several ways. Lum, F. M. et al. Complex immune dysregulation in COVID-19 patients with severe respiratory failure. The changes were most prominent at 4/5 dpc and thereafter were less severe, indicating resolution of the more acute changes observed at early time points. Histopathological changes with less severity observed at 14/15 dpc in cynomolgus macaques, with infiltration of mononuclear cells within alveolar spaces and bronchiolar lumen (e, arrows; bar=100m) and perivascular cuffing (f, arrow; bar=100m). Others, like V, describe an epitope created by some other mutation on the RHD and RHCE genes. [31] In addition to the case where D is deleted, crossover can also produce a single gene mixing exons from both RHD and RHCE, forming the majority of partial D types. The new analysis of the rhesus monkey genome, conducted by an international consortium of more than 170 scientists, also reveals that humans and the macaques share about 93 percent of their DNA.
