Evolution of Omicron lineage towards increased fitness in the upper respiratory tract in the absence of severe lung pathology

This study evaluates the fitness and pathogenesis of Omicron variants in the upper and lower respiratory tracts, finding increased URT fitness with reduced lung pathology.

Compartmentalized SARS-CoV-2 replication in upper versus lower respiratory tract after intranasal inoculation or aerosol exposure

This study compares SARS-CoV-2 replication in rhesus macaques after intranasal inoculation or aerosol exposure, finding differences in respiratory tract involvement.

SMARCB1 loss creates patient-specific MYC topologies that drive malignant rhabdoid tumor growth

This study shows that SMARCB1 loss leads to patient-specific MYC enhancer looping, driving MRT growth through epigenetic reprogramming.

SARS-CoV-2 Omicron BA.1 and BA.2 are attenuated in rhesus macaques as compared to Delta

This study compares disease severity and viral load in rhesus macaques infected with SARS-CoV-2 Delta, Omicron BA.1, and BA.2 variants, finding Omicron variants cause less severe disease with lower viral loads.

Mild SARS-CoV-2 infection in rhesus macaques is associated with viral control prior to antigen-specific T cell responses in tissues

This study shows that SARS-CoV-2 replication declines in the lungs before T cell responses, while innate immunity restricts viral replication in nasal and oral mucosa in rhesus macaques.

Age-related differences in immune dynamics during SARS-CoV-2 infection in rhesus macaques

This study compares immune dynamics in young and old rhesus macaques infected with SARS-CoV-2, finding age-related differences in post-acute immune responses but similar acute disease outcomes.

Subtle differences in the pathogenicity of SARS-CoV-2 variants of concern B.1.1.7 and B.1.351 in rhesus macaques

This study compares the pathogenicity of SARS-CoV-2 variants B.1.1.7 and B.1.351 in rhesus macaques, finding differences in clinical outcomes and immune responses.

Prior aerosol infection with lineage A SARS-CoV-2 variant protects hamsters from disease, but not reinfection with B.1.351 SARS-CoV-2 variant

ChAdOx1 nCoV-19 (AZD1222) protects Syrian hamsters against SARS-CoV-2 B.1.351 and B.1.1.7 1 disease

This study shows that the ChAdOx1 nCoV-19 vaccine protects Syrian hamsters from SARS-CoV-2 B.1.1.7 and B.1.351 variants, preventing weight loss, lung lesions, and viral replication.

SARS-CoV-2 infection dynamics in lungs of African green monkeys

This study examines SARS-CoV-2 infection dynamics in African green monkeys, showing viral replication in the lower respiratory tract and macrophage involvement in inflammation.

K18-hACE2 mice develop respiratory disease resembling severe COVID-19

This paper shows that K18-hACE2 mice develop severe respiratory disease upon SARS-CoV-2 infection, resembling human severe COVID-19 with lung pathology and systemic inflammation.

Hydroxychloroquine Proves Ineffective in Hamsters and Macaques Infected with SARS-CoV-2

This study shows hydroxychloroquine does not reduce SARS-CoV-2 replication or improve clinical outcomes in hamsters or macaques.

ChAdOx1 nCoV-19 vaccination prevents SARS-CoV-2 pneumonia in rhesus macaques

This study shows that the ChAdOx1 nCoV-19 vaccine reduces SARS-CoV-2 viral load and prevents pneumonia in rhesus macaques without causing immune-enhanced disease.

Clinical benefit of remdesivir in rhesus macaques infected with SARS-CoV-2

This study shows remdesivir reduces SARS-CoV-2 viral load and lung damage in rhesus macaques when administered early in infection.

Histone methyltransferase DOT1L controls state-specific identity during B cell differentiation

This study identifies DOT1L as a key regulator of B cell differentiation by controlling epigenetic programs that maintain B cell naivety and support germinal center formation.

Respiratory disease and virus shedding in rhesus macaques inoculated with SARS-CoV-2

This study shows that SARS-CoV-2 causes respiratory disease in rhesus macaques with symptoms similar to human cases, including prolonged viral shedding.

The histone methyltransferase DOT1L prevents antigen-independent differentiation and safeguards epigenetic identity of CD8+ T cells

This study shows that DOT1L prevents premature differentiation of CD8+ T cells and maintains their epigenetic identity, independent of antigen exposure.

Glucocorticoids regulate cancer cell dormancy

This study identifies the mechanism by which glucocorticoid receptor activation induces cancer cell dormancy through CDKN1C and FOXO1/IRS2 signaling, with implications for cancer therapy.

Mini viral RNAs act as innate immune agonists during influenza virus infection

This study identifies mini viral RNAs (mvRNAs) as activators of the RIG-I sensor, leading to interferon-beta expression and cytokine storm during influenza virus infection.
