Invited Speaker / Conférencier invité

Molecular machines are protein complexes that convert between different forms of energy, and they feature prominently in essentially any major cell biological process. A plausible hypothesis holds that evolution has sculpted these machines to efficiently transmit energy and information in their natural contexts, where energetic fluctuations are large and nonequilibrium driving forces are...

Organometallic chemical vapour deposited (OMCVD) gold nanoparticles (AuNPs) can be successfully used for biosensing. For the sensing mechanism an absorption feature, the localized surface plasmon resonance (LSPR), is implemented. Typically in this bio-sensing approach is monitoring the changes in the peak position of the LSPR via absorption spectroscopy during a highly specific binding...

The hematopoietic stem cell niche is a specialized bone marrow microenvironment where blood-forming cells reside. Interactions between these rare cells and their niche need to be studied at the single-cell level. While live animal cell tracking with optical microscopy has proven useful for this purpose, a more thorough characterization requires novel approaches. This can be accomplished by...

631. The oligomeric composition of the M2 muscarinic receptor and the G protein signalling complex: a single molecule study

The role of oligomers in signalling via G protein-coupled receptors (GPCRs) has been under debate. The oligomeric size of several GPCRs has been studied using fluorescence-based techniques and have provided inconsistent results, while their attendant G proteins have received little attention. In this study, the oligomeric nature of the GPCR signalling complex comprising the M2 muscarinic...

Transfer of lipid material between mulitlamellar reservoirs and the surface active layer is required to maintain the functional surfactant layer in alveoli. Surfactant Protein B (SP-B) is believed to facilitate interlayer contact implicit in such activity. The way in which SP-B might promote trafficking of surfactant material was investigated using mixtures bilayered micelles containing long-...
