Study Type/Review:
NPRC/Institute: Chinese Academy of Sciences; Henan Normal University; Guangzhou Medical University; Fudan University
Keywords: SARS-CoV-2, inflammation, lung pathology, immune response, primates
Summary of Study: SARS-CoV-2 triggers an immediate mast cell (MC) degranulation, which initiates the alveolar epithelial inflammation and disrupts the tight junction. MC stabilizers that block degranulation reduce virus-induced lung inflammation and injury.

NPRC/Institute: Nat'l Institute of Infectious Diseases, Tokyo; University of Tokyo; Kumamoto University

Summary of Study: Study showed that subacute SARS-CoV-2 replication can be controlled even in the absence of CD8+ T cells. In SARS-CoV-2 infection, CD8+ T-cell responses may contribute to viral control, but these results suggest that CD8+ T-cell dysfunction does not solely lead to viral control failure or disease progression.

NPRC/Institute: School of Biological Science and Medical Engineering, Beihang University, Beijing

Summary of Study: Four top prioritized linear B-cell epitopes in the hotspot regions of S protein can specifically bind with serum antibodies from rhesus monkeys inoculated with different SARS-CoV-2 vaccine candidates or a patient recovering from COVID-19. This study suggests that the four linear B-cell epitopes are potentially important candidates for serological assay or vaccine development.

Year Published:
Study Type/Review:
NPRC/Institute: University of Liverpool, Public Health England, University of Bristol, and others
Keywords: SARS-CoV-2, the leader-transcriptional regulatory sequence gene junction, high resolution sequencing, primates
Summary of Study: LeTRS, a bioinformatics tool, identified known leader-TRS-junctions and identified novel species that were common across different species. The data indicated multi-phasic abundance of sgmRNAs in two different NHP models, with spikes in sgmRNA abundance reflected in human samples, and therefore has implications for transmission models and nucleic acid-based diagnostics.

Year Published:
Study Type/Review:
NPRC/Institute: Rocky Mountain Laboratories/NIAID/NIH, University of Colorado School of Medicine
Keywords: SARS-CoV-2, T cells, immune response, pathology, primates
Summary of Study: T-cells play a role in the recovery of rhesus macaques from acute SARS-CoV-2 infections, although their depletion does not induce severe disease, and T cells do not account for the natural resistance of rhesus macaques to severed COVID-19. Neither primed CD4+ or CD8+ T cells appeared critical for immunoglobulin class switching, the development of immunological memory or protection from a second infection.

Year Published:
Study Type/Review:
NPRC/Institute: Univ. of Calgary, Institut de Biologia Evolutiva, New York Univ., and others
Keywords: SARS-CoV-2, ACE2 gene and protein sequences, several species, primates
Summary of Study: Susceptibility to SARS-CoV-2 is not equal across non-human primates. This study suggests that several clades of lemurs have a high potential susceptibility to SARS-CoV-2 infection. As they are among the primates at highest risk of extinction globally, further understanding of their risk should be a conservation priority. All feasible actions should be taken to limit their exposure to SARS-CoV-2.

Summary of Study: The Janssen Ad26.COV2.S vaccine candidate is currently the only one evaluated as a single dose vaccination regimen in Phase 3 clinical studies. This study showed that a second vaccine dose (administered 8 weeks post the first immunization) induced a significant increase in antigen-specific binding and neutralizing antibody responses in both adult and aged rhesus macaques as compared to a single dose. These data support the initiation of a two-dose Ad26.COV2.S regimen in Phase 3 clinical trial in adults and elderly.

Keywords: SARS-CoV-2, apoptosis in post-mortem lung, pathogenesis, primates
Summary of Study: Apoptosis was examined in post-mortem lung sections from COVID-19 patients and lung tissues from NHP models of SARS-CoV-2 infection. Multiple-target immunofluorescence assays and Western blotting suggest both intrinsic and extrinsic apoptotic pathways are activated during SARS-CoV-2 infection. These findings may help to delineate a novel insight into the pathogenesis of ARDS following SARS-CoV-2 infection.
