Remorins are multifunctional proteins, regulating immunity, development and symbiosis in plants. When associating to the membrane, remorins sequester specific lipids into functional membrane nanodomains. The multigenic protein family contains six groups, classified upon their protein-domain composition.

Article Synopsis
- Flotillins are scaffolding proteins that play a key role in organizing membranes in various organisms, from archaea to mammals, with a complex structure consisting of multiple functional domains.
- In the bacterium B. subtilis, the flotillins FloT and FloA localize to specific nanodomains and have various cellular functions, impacting membrane organization.
- Research using NMR techniques reveals that FloT and FloA can cause disorder in model membranes, affecting their structure and function, with implications for understanding cellular processes.
A perforated silica layer with structural correlation is engineered using sol-gel chemistry, applied to large-scale flat and curved surfaces. The anion(s) used in the preparation give tailored spatial correlation, and control over perforation size and density. Surface structuration is rapidly and reproducibly created using water and salts as inexpensive and ecofriendly reagents.

- Many microorganisms, including bacteria, fungi, and plants, have a protective cell wall that offers strength and protection, especially important for pathogens during host interaction.
- Solid-state NMR has gained attention as a technique to analyze the molecular structure of these cell walls, focusing on the composition of polysaccharides.
- This study explores a method called DREAM to enhance NMR analysis, showcasing its effectiveness in identifying polysaccharide signals in intact fungal cells, and discussing its potential for studying more complex cell surfaces.
Signalosomes are high-order protein machineries involved in complex mechanisms controlling regulated immune defense and cell death execution. The immune response is initiated by the recognition of exogeneous or endogenous signals, triggering the signalosome assembly process. The final step of signalosome fate often involves membrane-targeting and activation of pore-forming execution domains, leading to membrane disruption and ultimately cell death.
