SARS-CoV-2 ORF10 degrades mitochondrial antiviral signaling protein to suppress immune response

A novel mechanism by which SARS-CoV-2 inhibits the innate immune response; that is, ORF10 induces mitophagy-mediated MAVS degradation by binding to NIX.

Role of interferon type I-driven responses associated with disease control in COVID-19

New research suggests that treatment with type I interferons in the early stage of COVID-19 may supress disease progression by limiting SARS-CoV-2 in hosts.

Human LRRC15 protein is an inhibitory receptor for SARS-CoV-2 spike-mediated entry

In a recent study, published on the bioRxiv* preprint server, researchers identified human LRRC15 as an inhibitory receptor for SARS-CoV-2 entry, which directly binds to the receptor-binding domain (RBD) of the spike protein with a moderate affinity and inhibits spike-mediated entry.

Study shows plasmacytoid dendritic cells may be a viable target for protection against SARS-CoV-2

A recent research paper by scientists from Denmark reveals that circulating plasmacytoid dendritic cells may be a potential therapeutic target to maintain desired levels of an antiviral compound known as interferon, allowing for the mitigation of coronavirus disease (COVID-19) severity. The study is currently available on the bioRxiv* preprint server while it undergoes peer review.

Immune response to influenza virus influenced by genetic ancestry

New research at the University of Chicago has found differences in immune pathway activation to influenza infection between individuals of European and African genetic ancestry.

Study finds rhinovirus reduces SARS-CoV-2 replication in airway epithelial cells

A recent study has demonstrated that SARS-CoV-2 infection induces a significantly lower interferon response than rhinovirus infection.

Discovery of a broad-spectrum antiviral activity in self-assembling immunostimulatory duplex RNAs

A new study, published on the bioRxiv* preprint server, has discovered a class of new immunostimulatory RNAs while studying influenza infection-associated host genes in human lung epithelial cells using small interfering RNAs (siRNAs). Scientists revealed that these short duplex RNAs could induce type I and type III interferons (IFN-I/III) in a wide variety of cells.

Interferon beta versus the SARS-CoV-2 Delta variant

In a study recently published on the bioRxiv* preprint server, researchers investigated the difference in replication efficiency or IFN sensitivity of the four VOCs.

Newly discovered RNA molecule protects mice from emerging SARS-CoV-2 variants

Researchers at Yale School of Medicine have discovered that an RNA molecule that stimulates the body's early antiviral defense system can protect mice from a range of emerging SARS-CoV-2 variants.

Interferon beta-1a plus remdesivir not superior to remdesivir alone in hospitalized COVID-19 patients

A clinical trial has found that treatment with the immunomodulator interferon beta-1a plus the antiviral remdesivir was not superior to treatment with remdesivir alone in hospitalized adults with COVID-19 pneumonia.

The role of ZBP1 in promoting SARS-CoV-2-induced cytokine expression

A new study reported that the ZBP1-induced inflammatory signaling pathway is dependent on ubiquitination and RIPK3’s scaffolding ability, independent of cell death.

Defect in the interferon system associated with more severe COVID-19

A component of the human interferon system that activates SARS-CoV-2 cellular defenses appears to be defective in a proportion of humans, new research reports. COVID-19 outcomes were more severe in hospitalized patients who exhibited this immune system deficit, the study shows.

Caspase-11 identified as regulator of inflammatory pathology in SARS-CoV-2 infections

New findings identify CASP4/11 as detrimental to inflammation and coagulopathy associated with SARS-CoV-2 infection.

Infections impact blood vessel repair within the meninges following TBI or other cerebrovascular injuries

Viral Infection Slows Blood Vessel Repair After TBI: Seven days after mTBI, the blood vessels (stained in red) in the tissues around the brain are not completely repaired. A marker for intact vessels was used (labeled in green) to distinguish fully functional blood vessels (yellow) from ones that are still damaged (red).McGavern Lab, NINDS
