Researchers discover titanium oxide nanoparticle that recognizes SARS-CoV-2’s non-structural protein 1

A pioneering study reports on the interaction of a tailored titanium oxide nanoparticle (NP) with the full-length SARS-CoV-2 non-structural protein 1 (nsp1). This should be of value in developing new therapeutic tools against coronaviruses that act by targeting their proteins. It could also help map the structure of activated proteins.

Polyuridine sequence of mouse coronavirus can be targeted to prevent host cell death

A new study reports the use of a modified deoxyribonucleic acid (DNA) oligonucleotide that has a 3’ polyadenine (polyA) tail to bind to the 5’-polyU tract in the mouse coronavirus (MHV-A59). Treatment of mouse cells infected with MHV-A59 with this molecule led to a marked reduction in cell deaths.

SARS-CoV-2 Q493R protein mutation shows resistance to monoclonal antibodies

The Centers for Disease Control and Prevention (CDC) issued a letter detailing a case of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in an immunocompromised patient who did not respond well to monoclonal antibody treatment. The resistance to treatment stemmed from an escape mutation on the spike protein known as Q4923R.

SARS-CoV-2 variants of concern employ different strategies of antibody escape

A recent study in the field of fluid analysis reveals a diverse set of strategies utilized by alpha and beta variants of the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) in order to evade antibodies generated during an earlier infection with this virus. The paper is currently available on the bioRxiv* preprint server while it undergoes a peer-review process.

Monoclonal antibody CT-P59 demonstrates potent antiviral efficacy against SARS-CoV-2 delta variant

A Korean study has recently demonstrated antiviral potency of monoclonal antibody CT-P59 against the delta variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The experiments conducted in animals infected with the delta variant have shown that CT-P59 is able to reduce symptom intensity and viral replication in the respiratory tract. The study is currently available on the bioRxiv* preprint server.
