Atlas of Interactions Between Decoration Proteins and Major Capsid Proteins of Coliphage N4.

Coliphage N4 is a representative species of the family of bacteriophages. Originally structurally studied in 2008, the capsid structure was solved to 14 Å to reveal an interesting arrangement of Ig-like decoration proteins across the surface of the capsid. Herein, we present a high-resolution N4 structure, reporting a 2.

DJK-5, an anti-biofilm peptide, increases Staphylococcus aureus sensitivity to colistin killing in co-biofilms with Pseudomonas aeruginosa.

Chronic infections represent a significant global health and economic challenge. Biofilms, which are bacterial communities encased in an extracellular polysaccharide matrix, contribute to approximately 80% of these infections. In particular, pathogens such as Pseudomonas aeruginosa and Staphylococcus aureus are frequently co-isolated from the sputum of patients with cystic fibrosis and are commonly found in chronic wound infections.

Engineered bispecific antibodies with enhanced breadth and potency against SARS-CoV-2 variants and SARS-related coronaviruses.

The concern of COVID-19 persists due to the continuous emergence of variants and the potential spillover of animal coronaviruses. The broad-spectrum neutralizing antibodies play a pivotal role in the prevention and treatment of coronavirus (CoV) infections. Here, we constructed 18 bi-specific antibodies (bsAbs) using 9 antibodies isolated from COVID-19 convalescents and vaccinated individuals, designed as dual variable domain immunoglobulin (DVD-Ig).

Evidence for phospholipid self-organisation in concentrated ammonia-water environments.

Titan, the largest moon of Saturn is thought to have the potential to support primordial life. The surface of Titan contains bodies of liquid hydrocarbons, and modelling suggests that an ammonia-water ocean resides deep beneath the surface, both of which have been speculated to support primordial chemistry. Here we present the first evidence that both preformed and self-organised phospholipid vesicles remain stable and can maintain concentration gradients in ammonia-water environments; a fundamental requirement for primordial chemistry and biology to originate.
