In general, there was a trend for spike protein peptide-specific IFN- SFU frequencies measured in PBMC samples collected from cynomolgus macaques to be greater than those detected in rhesus macaques, although these differences did not reach statistical significance. Check out up-to-date information for all showings, events, activities, and happenings this week. Non-tissue samples were inactivated in AVL (Qiagen) and ethanol, with final extraction using the QIAamp Viral RNA Minikit (Qiagen) as per manufacturers instructions. ". Throat and rectal swabs were processed, and aliquots stored in viral transport media (VTM) and AVL buffer (Qiagen, Milton Keynes, UK) at 80C until assay. Samples collected from the upper respiratory tract at each study time point were evaluated using a Vero cell-based plaque assay for the presence of viable virus. IgG seroconversion occurred in both macaque species from days 8-9 post-infection and therefore follows a similar kinetic to serology profiles measured in COVID-19 patients33, indicating that both species offer representative models for the investigation of SARS-CoV-2 related humoral immunity. In addition, the rhesus serves as a valuable model for studying other human infectious diseases and for vaccine research. Did we get it from Rhesus monkeys? Vabret, N. et al. However viral RNA levels above the LLOQ were detected at both 3 and 5 dpc in cynomolgus macaques in comparison to 2 and 3 dpc in rhesus macaques (Fig. 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. Scans were evaluated by an expert thoracic radiologist, blinded to the animals clinical status, for the presence of: disease features characteristic of COVID-19 in humans (ground glass opacity (GGO), consolidation, crazy paving, nodules, peri-lobular consolidation; distribution: upper, middle, lower, central 2/3, bronchocentric); pulmonary embolus and the extent of any abnormalities estimated (<25%, 2550%, 5175%, 76100%). Immunol. Similarly, this pattern was seen with interferon production and response to virus for both species. 2A ). And while there's potentially bias in studying only 23andMe customers, both study authors and other experts in the field said it would be hard for a single research institution, or even a government agency, to perform a study of this magnitude and complexity. Macroscopic changes, considered to be associated with infection, were not observed in any other organ analysed in this study at any time point. Cytotoxic and immunomodulatory natural killer (NK) cell populations were identified within the CD3, CD159a+ lymphocyte population based on the expression on CD16 and CD56, respectively. de Groot, R. J. et al. Staining was not seen in cells or fluid within the alveolar spaces. The frequency of Th17 and TNF- expressing cells differed between the species with IL-17 producing CD4 and CD8 T-cells more prevalent in rhesus macaques, whereas TNF expression was detected more frequently in cynomolgus macaques. The second pregnancy (April, 1941) resulted in an infant with icterus gravis. In this respect, genotyping of blood groups has much simplified this detection of the various variants in the Rh blood group system. [15], In the past, partial D was called 'D mosaic' or 'D variant.' 9k). Isolation and rapid sharing of the 2019 novel coronavirus (SARS-CoV-2) from the first patient diagnosed with COVID-19 in Australia. In cynomolgus macaques, viral RNA was similarly detected at a low level in rectal swabs from 1 to 9 dpc. performed animal procedures and sampling processing. The module function was identified by dual enrichment. Weight and body temperature were monitored daily (Fig. Juno, J. Cytokine-producing CD4 and CD8 T-cells were detected in both rhesus and cynomolgus macaques in response to stimulation with M, N and S peptide pools. A rhesus macaque pictured at the Southwest National Primate Research Center. The research also raised a few surprises. Neutralising antibodies were observed at 89 dpc at low levels, increasing from 11 dpc onwards, with higher values in cynomolgus macaques compared to rhesus. Rhesus and cynomolgus macaques were inoculated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and culled in groups at three time points (4/5; 14/15 and 18/19 dpc). Other animals with Rh-like antigens causing hemolytic disease of the newborn, Rh disease only occurs in human fetuses however a similar disease called Neonatal isoerythrolysis (NI) can be observed in animal species of newborn horses, mules, pigs, cats, cattle, and dogs. The sequence of the rhesus macaque's genome will be a powerful tool for research with the monkeys aimed at understanding human biology, said consortium leader Richard Gibbs, director of the Baylor College of Medicine's Human Genome Sequencing Center in Houston. 1). Weak D may also occur as "C in trans", whereby a C gene is present on the opposite chromosome to a D gene (as in the combination R0r', or "Dce/dCe"). RhD-negative compared to RhD-positive subjects without anamnestic titres of anti-Toxoplasma antibodies have shorter reaction times in tests of simple reaction times. Immunological features were more typical of those reported in milder infections and convalescent patients and included changes in the frequency of CD4 and CD8 T-cell populations35 as well as increased frequencies of immunomodulatory NK36 and monocyte subsets37. Macaque model for severe acute respiratory syndrome. This included the detection of antigen-specific immune responses directed toward peptide-epitopes spanning the S protein sequence, an antigen incorporated into several of the novel vaccine candidates currently under investigation41, thus demonstrating the value of the macaque model for immunogenicity testing of novel SARS-CoV-2 vaccine candidates. The rhesus monkey genome sequence should prove invaluable to biomedical research, said physician scientist Ajit Varki at the University of California at San Diego, who participated in the chimpanzee genome sequencing project. ASCP Quick Compendium of Clinical Pathology, 2nd Ed. 50, 3947 (2011). Viable virus was successfully recovered from two of the six rhesus macaques and three of the six cynomolgus macaques on the first occasion of sampling (13 dpc). [44] Its properties make it attractive in numerous medical applications, but scarcity makes it expensive to transport and acquire. 4g and 4h). In addition, samples were stained using the RNAscope technique to identify the SARS-CoV-2 virus RNA. "Many Americans claim ancestry they don't have or don't claim ancestry that they do," said Saunt. CD107a was detected on CD8 and T-cells in both rhesus and cynomolgus macaques, was most potently induced by stimulation with the M protein peptide pool and detected at higher frequency in cynomolgus macaques at the early post-infection time points (Fig. DNA Comparison Provides New Clues to Primate Biology. Lancet Infect. Therefore, partial D patients who are donating blood should be labeled as D-positive but, if receiving blood, they should be labeled as D-negative and receive D-negative units. Nat Commun 12, 1260 (2021). rhesus monkey: [noun] a pale brown Asian macaque (Macaca mulatta) often used in medical research — called also#R##N# rhesus, rhesus macaque. CD4 T-cell dependent mechanisms of protection have been demonstrated in small animal models of SARS-CoV infection39, T-cells are likely to play an important role in the development of neutralising antibodies40 and the clearance of infection through cell-mediated cytotoxicity32. Internet Explorer). And ancestry patterns appeared to mirror major population shifts tied to historical events in American history. Due to their obvious physiological similarities to humans, non-human primates (NHPs), such as macaques, have long been recognised as the most clinically relevant animal for the development of in vivo models of human disease. The presence of viral RNA was observed in the lungs from all animals at 4/5 dpc by in situ hybridisation (ISH). When any incompatibility is detected, the mother often receives an injection at 28 weeks gestation and at birth to avoid the development of antibodies towards the fetus. National Institutes of Health, 9000 Rockville Pike, Bethesda, Maryland 20892, U.S. Department of Health and Human Services, U.S. Department of Health & Human Services, NIH Institute and Center Contact Information. Similar to antennas on stereo to catch radio signals, antigens are present on cells to read signals from their environment. Results were calculated to report as spot forming units (SFU) per million cells. Subbarao, K. & Roberts, A. The images or other third party material in this article are included in the articles Creative Commons license, unless indicated otherwise in a credit line to the material. One of the most useful features of the rhesus genome is that it is less closely related to the human genome than to the chimp genome. March 22, 2023 . Because the most active newborn animals consume the most colostrum, they may be the ones who are most affected by the blood incompatibility of antigen and antibody. Furthermore, there was an increased prominence of bronchial-associated lymphoid tissue (BALT) was noted. Sign up for the Nature Briefing: Translational Research newsletter top stories in biotechnology, drug discovery and pharma. The rhesus study is part of an ongoing program to analyze primate genomes. The CDE notation used in the FisherRace nomenclature is sometimes rearranged to DCE to more accurately represent the co-location of the C and E encoding on the RhCE gene, and to make interpretation easier.

In addition, the improved consistency in outcome facilitates the use of fewer animals to obtain statistically significant results than would be required if more genetically diverse species were to be used. D individuals who lack a functional RHD gene do not produce the D antigen, and may be immunized by D+ blood. Visit our corporate site (opens in new tab). By adding the rhesus genome to the primate comparison, researchers identified nearly 200 genes likely to be key players in determining differences among primate species. The induction of a proinflammatory cytokine storm has been described in human COVID-19 patients, with IL-6 levels significantly elevated and associated with the disease severity30,31. No significant weight loss or changes in body temperature were observed throughout the experiment. Simply put, the weak D phenotype is due to a reduced number of D antigens on a red blood cell. SARS-CoV-2 infection protects against rechallenge in rhesus macaques. Just like Rh molecules, Amt carries and distributes gas within cells. To obtain Epidemiological and clinical characteristics of 99 cases of 2019 novel coronavirus pneumonia in Wuhan, China: a descriptive study. Wiener's notation is more complex and cumbersome for routine use. Viral RNA was not detected in nave animals. 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. [42]:322 By definition, weak D phenotype is characterized by negative reaction with anti-D reagent at immediate spin (IS), negative reaction after 37C incubation, and positive reaction at anti-human globulin (AHG) phase. In rhesus macaques, low levels of viral RNA were detected from 1 to 9 dpc. Following challenge animals were transferred to ACDP Level three and housed in banks of cages of similar construction placed in directional airflow containment systems that allowed group housing and environmental control whilst providing a continuous, standardised inward flow of fully conditioned fresh air identical for all groups. Future US, Inc. Full 7th Floor, 130 West 42nd Street, Similar to recent NHP studies, a dose of 5 106 pfu of SARS-CoV-2/Victoria/01/202015, was delivered via the intranasal (IN) and intratracheal (IT) route to groups of each species comprising six animals. Following incubation, cells were washed with FACS buffer consisting of PBS+1% FCS and incubated for 30min at room temperature with optimal dilutions of the amine-reactive Live/Dead Fixable Red viability cell stain (Life Technologies) and the antibodies CD4 PerCP-Cy5.5, CD8 APC-Fire750, CD69-BV510, (all from BD Biosciences) and CD20- Pe-Dazzle-594, -TCR-BV421 (Biolegend, London, UK) prepared in BD Biosciences Brilliant stain buffer (BD Biosciences, Oxford, UK). 58, e0096300919 (2019). Google Scholar. Rhesus factor has an even more ancient origin. Following the initial 2h of incubation, the protein transport inhibitor Brefeldin-A (Sigma) was added at a final concentration of 10g/ml. Its the + or - in A+, B-, O+, etc. Rhesus factor has an even more ancient origin. 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. Occasional multinucleated cells are observed (b, insert; bar=20m). Nature 581, 465469 (2020). There are other posts on this site that talk about the basics of Rhesus factor, so here I will talk more about the evolution of Rhesus factor, and blood type in animals. 3). Herold, T. et al. Before the start of the experiment, socially compatible animals were randomly assigned to challenge groups, to minimise bias. And conversely, RhD-negative subjects with anamnestic titres (i.e. The sequencing of the rhesus genome was conducted at the Baylor College of Medicine Human Genome Sequencing Center in Houston, the Genome Sequencing Center at Washington University School of Medicine in St. Louis and the J. Craig Venter Institute in Rockville, Md., which are part of the NHGRI-supported Large-Scale Sequencing Research Network. ", "Blood Type Frequencies by Country including the Rh Factor Rhesus Negative", "Re: Is the RH negative blood type more prevalent in certain ethnic groups? Methods 12, 357360 (2015). Gating strategy for flow cytometry analyses are summarised in Supplementary Figs. Go to the top of the page Help. Genes with a similar function were clustered together into consensus modules to allow different traits (sex of the animal and days post-infection) to be compared. We compare the transcriptomes of three biological replicates of ORMES6 (A, B and C) with pooled differentiated EBs to identify 367 rhesus monkey putative stemness genes. The software package PESTLE version 1.7 (Mario Roederer, Vaccine Research Centre, NIAID, NIH) was used for background subtraction to obtain antigen-specific polyfunctional ICS cytokine responses, Graphpad Prism (version 8.0.1) was used to generate graphical representations of flow cytometry data. More than 30 different partial D phenotypes have been described.[15]. The rhesus macaque is the third primate genome to be completed, work that promises to greatly enhance understanding of primate evolution, perhaps even to help explain what makes us human. "This article uses another tool, DNA analysis, to get at the same question.". It's descended from a molecule called Amt. Animals were challenged with a total of 5 106 pfu of SARS-CoV-2/Victoria/01/2020 administered in volumes of 2ml by the intratracheal route (using a bronchoscope for accurate placement right above the carinal bifurcation) and 1ml by the intranasal route (0.5ml in each nostril). 51. Results: We quantified A3G and A3F mRNA in PBMC and leukocyte subsets of uninfected and SIVmac-infected rhesus macaques. Recently, numerous cytochrome P450 (P450 or CYP) cDNAs have been identified and characterized in Virus titre of the challenge stocks was determined by plaque assay on Vero/E6 cells [ECACC 85020206]. [15][43], The first Rhnull blood was discovered in an Aboriginal Australian woman, in 1961. The cells were assayed at 2 105 cells per well, unless there were not enough cells, in which case 1 105 cells were used. Airway memory CD4(+) T cells mediate protective. [44] As a consequence of Rh antigen absence, Rhnull red blood cells also lack LW and Fy5 and show weak expression of S, s, and U antigens. The lack of clinical signs observed agrees with other reports that used the IN and IT routes of challenge delivery11,13,18,20. Biologically independent animal samples for (ad); PBMCs: nave n=6, early n=2, late n=4 Biologically independent animal samples for (e); lung and spleen: early n=2, late n=4, (fj) Frequency of major lymphocyte and monocyte cell populations quantified by immunophenotyping assay (fh) CD4+, CD8+ and T-cell frequencies in PBMCs and lung cells, (i) Monocyte subtype frequency in PBMCs and lung MNCs, (j) Natural killer (NK) cell subset frequency in PBMCs and lung MNCs. Mod. In addition, samples were stained using the RNAscope technique to identify the SARS-CoV-2 virus RNA or Interleukin 6 (IL-6) in lung tissue sections. Transl.
