ABO blood group and COVID-19: a review on behalf of the ISBT COVID-19 working group


Authors: the ISBT COVID-19 Working Group School of Medicine Abstract Growing evidence suggests that ABO blood group may play a role in the immunopathogenesis of SARS-CoV-2 infection, with group O individuals less likely to test positive and group A conferring a higher susceptibility to infection and propensity to severe disease. The level of evidence supporting […]

Role of neutrophil-epithelial interactions in SARS-CoV-2 infection


Authors: By Suchandrima BhowmikAug 15 2021Reviewed by Benedette Cuffari, M.Sc. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is the virus that causes coronavirus disease 2019 (COVID-19), is associated with high mortality and hospitalization rates. However, many patients who are infected with SARS-CoV-2 remain asymptomatic or develop mild symptoms. In a recent study published on the […]

Intracellular localization of the SARS coronavirus protein 9b: evidence of active export from the nucleus


Authors: Igor Moshynskyy 1, Sathiyanarayanan Viswanathan, Natalia Vasilenko, Vladislav Lobanov, Martin Petric, Lorne A Babiuk, Alexander N Zakhartchouk Abstract Open reading frame 9b (ORF 9b) encodes a 98 amino acid group-specific protein of severe acute respiratory syndrome (SARS) coronavirus (CoV). It has no homology with known proteins and its function in SARS CoV replication has not been determined. The N-terminal part of […]

The Crystal Structure of ORF-9b, a Lipid Binding Protein from the SARS Coronavirus


Author links open overlay panelChristophMeier123A. RaduAricescu13ReneAssenberg2Robin T.Aplin2Robert J.C.Gilbert13Jonathan M.Grimes123David I.Stuart123 Summary To achieve the greatest output from their limited genomes, viruses frequently make use of alternative open reading frames, in which translation is initiated from a start codon within an existing gene and, being out of frame, gives rise to a distinct protein product. These alternative protein products are, as yet, […]

UniProtKB – P59636 (ORF9B_SARS)


Protein: ORF9b protein database Gene: 9b Organism Severe acute respiratory syndrome coronavirus (SARS-CoV) Status Reviewed-Annotation score:-Experimental evidence at protein leveli Functioni Plays a role in the inhibition of host innate immune response by targeting the mitochondrial-associated adapter MAVS. Mechanistically, usurps the E3 ligase ITCH to trigger the degradation of MAVS, TRAF3, and TRAF6. In addition, […]

SARS-coronavirus open reading frame-9b suppresses innate immunity by targeting mitochondria and the AVS/TRAF3/TRAF6 signalosome


.J Immunol 2014 Sep 15;193(6):3080-9. doi: 10.4049/jimmunol.1303196. Epub 2014 Aug 18.

Inflammasome activation at the crux of severe COVID-19


Authors: Setu M. Vora,1,2Judy Lieberman,2,3 and Hao Wu1,2 Abstract The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), results in life-threatening disease in a minority of patients, especially elderly people and those with co-morbidities such as obesity and diabetes. Severe disease is characterized by dysregulated cytokine release, pneumonia and acute lung injury, which can […]
