Immune memory B cells in people with cystic fibrosis contain bacteria-specific sequences that could be used to make new treatments for life-threatening infections.
A MASLD mouse model reveals that gut-derived Gram-negative bacterial lipopolysaccharides promote hepatic lipid accumulation and acyloxyacyl hydrolase, a host lipase that degrades and inactivates lipopolysaccharides and mitigates MASLD.
Larger dendritic diameter, increased conductance load at the soma, and differences in cable and ion channel properties enable faster signal propagation in human neocortical dendrites, preserving information processing speed.

Purkinje cells influence postural control in developing zebrafish, revealing age-dependent cerebellar contributions to balance and establishing a powerful model for studying cerebellar control of postural maturation.
Disruption of RAS–p110α signalling in macrophages impairs both the initiation and resolution of inflammatory responses, revealing a critical regulatory role in immune function and inflammation control.
The distributed network of working memory, encompassing frontal, parietal, and sensory cortices, flexibly reconfigures under different tasks to adapt to varying control demands.
Islet cholesterol levels determine GLP-1R function, with several cholesterol-binding sites mapped in active vs inactive receptors and one, containing Val229, shown to control GLP-1R behaviour in beta cell models.
