A genetically-encoded nanobody sensor reveals conformational diversity in beta-arrestins orchestrated by distinct seven transmembrane receptors

This study introduces a nanobody sensor to detect conformational changes in beta-arrestins upon GPCR activation, revealing receptor-specific conformational diversity.

Molecular insights into atypical modes of beta-arrestin interaction with seven transmembrane receptors

This study presents cryo-EM structures and experimental data revealing how beta-arrestins interact with GPCRs, particularly those with phosphorylation in the third intracellular loop and intrinsically biased receptors.

Structure-guided engineering of biased-agonism in the human niacin receptor via single amino acid substitution

This study presents cryo-EM structures of GPR109A-G-protein complexes with agonists and uses them to engineer biased agonists with reduced flushing effects.

Vaginal microbiome-host interactions modeled in a human vagina-on-a-chip

This paper develops a human vagina-on-a-chip model to study vaginal microbiome-host interactions and their effects on health outcomes.

Predicting drug concentrations in PDMS microfluidic organ chips

This paper develops a simulation and experimental method to predict drug concentration profiles in PDMS microfluidic organ chips without prior knowledge of log P or diffusion rates.

Lymphoid follicle formation and human vaccination responses recapitulated in an organ-on-a-chip

This paper demonstrates the formation of lymphoid follicles in a human organ-on-a-chip model and shows improved vaccine responses compared to 2D cultures.

Growth behavior and glyphosate resistance level in 10 biotypes of Echinochloa colona in Australia

This study examines growth behavior and glyphosate resistance in 10 biotypes of Echinochloa colona in Australia, finding significant variation in growth traits and resistance levels, with some biotypes being highly resistant and productive.
