Year Published: 2020
Study Type/Review:
NPRC/Institute: Tongji Medical College, Wuhan, China
Keywords: SARS, ACE2, receptor-binding domain, pneumonia
Summary of Study: The authors analyzed 82 representative ACE2 sequences from the 1000 sequences with the closest homology to the human ACE2 protein to identify potential SARS-CoV-2 natural and intermediate hosts, as well as susceptible animals. Results suggest that several NHPs may be intermediate hosts and most are susceptible to SARS-CoV-2.

Summary of Study: Four, aged, AGMs were exposed by two routes to SARS-CoV-2 isolate USA-WA1/2020. The study reports fatal ARDS in two of the infected animals, demonstrating pathological lesions and disease similar to severe COVID-19 in humans. Three of the four infected AGMs showed cytokine storm, and all four animals showed increased levels of IL-6 in plasma. These results suggest the AGM is a useful model to study disease pathogenesis of SARS-CoV-2.

Summary of Study: This study uncovers critical steps in the immune events of the host response to SARS-CoV-2 and describes the correlates of viral replication and disease progression. The authors show viral driven inflammation/cell recruitment to the lung occurs rapidly, and lasts up to 4 weeks post-infection. Results suggest that NHP may be appropriate models to test immune therapies.

Keywords: SARS-CoV-2, Baricitinib, immunologic and virologic efficacy, primates
Summary of Study: The authors investigated the immunologic and virologic efficacy of baricitinib in a rhesus macaque model of SARS-CoV-2 infection. Animals treated with baricitinib showed reduced inflammation, decreased lung infiltration of inflammatory cells, reduced NETosis activity, and more limited lung pathology. These data support a beneficial role for the use of baricitinib as a frontline treatment for inflammation induced by SARS-CoV-2 infection.

Keywords: coronavirus, SARS-CoV-2, protective immunity
Summary of Study: Rhesus macaques were inoculated intranasally and intratracheally with SARS-CoV-2, which induced humoral and cellular immune responses and provided protective efficacy against SARS-CoV-2 rechallenge. These data raise the possibility that immunologic approaches to the prevention and treatment of SARS-CoV-2 may be effective.

Keywords: beta coronaviruses, SARS-CoV-2, receptor sequence binding
Summary of Study: Authors show that host protease processing during viral entry is a significant barrier for several lineage B viruses and that bypassing this barrier allows several lineage B viruses to enter human cells through an unknown receptor. They also demonstrate how different lineage B viruses can recombine to gain entry into human cells, and confirm that human ACE2 is the receptor for the recently emerging SARS-CoV-2.
