Small Multivalent Architectures Mimicking Homotrimers of the TNF Superfamily Member CD40L: Delineating the Relationship between Structure and Effector Function
Synthetic multivalent ligands, owing to the presence of multiple copies of a recognition motif attached to a central scaffold, can mediate clustering of cell surface receptors and thereby function as effectormolecules. This paper dissects the relationship between structure and effector function of synthetic multivalent ligands targeting CD40, a cell surface receptor of the tumor necrosis factor receptor

A probe is provided comprising a label and a binding moiety, wherein the binding moiety is adapted to bind to gram-negative bacteria, and to substantially not bind to animal cells or gram-positive bacteria. A method of detecting the presence of bacteria in a target area is also provided, which allows the detection of bacteria generally, and the determination of whether that bacteria is gram negative or gram positive.

Optical probes are presented, the probes comprising a first probe element, and a second probe element connected to a core. The first probe element comprises a first fluorophore connected to a first quencher by a first cleavable linker. The second probe element comprises a second fluorophore connected to a second quencher by a second cleavable linker. The first fluorophore is separated from the first quencher when the first cleavable linker is cleaved, and the second fluorophore is separated from the second quencher when the second cleavable linker is cleaved. Methods of detecting a first and second enzyme using the optical probe are also presented.
The present invention relates to methods of visualising cells especially although not exclusively in vivo using a dye, such as a dendrimer-dye molecule or polybranched-dye molecule which is internalised by the cells and thus permits subsequent visualisation by confocal fluorescence endomicroscopy or other optical detectors. There is also provided internally quenched probes for use in visualising cells especially although not exclusively in vivo by confocal fluorescence endomicroscopy and the use of internally quenched probes in combination with confocal fluorescence endomicroscopy, for visualising cells by virtue of internalisation and dequenching of a probe by the cells. In a particular embodiment the cells are activated neutrophils, such as within the lung of a subject.
