Method for inactivation and direct RT-qPCR of SARS-CoV-2

Researchers from the University of Edinburgh have been exploring ways to optimize this process further, allowing RT-qPCR to work more efficiently by eliminating one of the key steps.

COVID-19 severity is correlated with T cell receptor repertoire signatures

In a new study published in the bioRxiv* preprint server, researchers found that specific TCR sequences predicted the severity of coronavirus disease 2019 (COVID-19) infection. Additionally, there was evidence of increased CDR3 sequences and changes in k-mer motifs for patients with severe illness.

SARS-CoV-2 S2 immunization as a pan-coronavirus vaccine approach

A new mouse model suggests that prior HCoV-OC43 S immunity primes neutralising antibody responses to otherwise subimmunogenic SARS-CoV-2 S exposure as well as promotes S2-targeting antibody responses.

Scientists find infection of sustentacular cells in the olfactory epithelium of COVID-19 patients

It is now widely known that COVID-19 is associated with the transient or long-term loss of olfaction (the sense of smell) but the mechanisms remain obscure.

SARS-CoV-2 Delta saliva viral load 15 times that of the wild type

Researchers hypothesize that a higher viral load of SARS-CoV-2 Delta variant in saliva contributes to its high transmissibility.

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.
