A new COVID-19 candidate vaccine induces robust humoral and cellular immune responses in mice

A Korea-based company EyeGene Inc. has recently developed a liposome-based mRNA candidate vaccine against COVID-19, which contains full-length spike protein of the European variant (D614G) of SARS-CoV-2 as a vaccine antigen.

Could nanoparticle vaccines offer broad protection against sarbecoviruses?

To understand the ability of SARS-CoV-2 vaccine-elicited antibodies to neutralize and protect against emerging variants (that are pathogenic) and other sarbecoviruses, a large team of researchers studied immunity by receptor-binding domain nanoparticle vaccines. They showed that a clinical-stage multivalent SARS-CoV-2 receptor-binding domain nanoparticle vaccine (SARS-CoV-2 RBD-NP) protected mice from the SARS-CoV-2-induced disease.

Study maps crucial component of long-term immune response to SARS-CoV-2

Researchers in the United States have found that protective antibodies generated against the original strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)– the agent that causes coronavirus disease 2019 (COVID-19) – also protect against viral variants.

Proteomics shows SARS-CoV-2 NSP7 and NSP8 forms stable dimeric unit

A new preprint, released on the bioRxiv* preprint server, describes the structure of part of the dynamic protein-RNA complex known as the replication-transcription complex (RTC), which is crucial in the replication of the large ribonucleic acid (RNA) genome of this virus.

Scientists optimize wastewater disinfection process to minimize spread of antibiotic resistance

Antibiotic-resistant bacteria have become a global threat today, owing in part to the efficiency with which resistance spreads among them. Some of this spread happens in waterbodies—and our wastewater systems are no exception.

Newly discovered protein regulates molecular motors in response to light

Single-celled algae and animal sperm cells are widely separated in evolution but both swim in the same way, by waving their protruding hairs, called cilia or flagella. Motion is driven by molecular motors, complex assemblies of proteins that exert a force when changing shape.

Structure of SARS-CoV-2 envelope protein-epithelial cell junction protein complex explains virulence

A new study by researchers at Brookhaven National Laboratory and Stony Brook University in the U.S. describes the key interaction between the viral envelope (E) protein and the human cell junction protein, PALS1. The latter is necessary to establish and maintain cell polarity and tight junctions between cells.
