Structure and dynamics of dynorphin peptide and its receptor [PDF]
Dynorphin is a neuropeptide involved in pain, addiction and mood regulation. It exerts its activity by binding to the kappa opioid receptor (KOP) which belongs to the large family of G-protein coupled receptors. The dynorphin peptide was discovered in 1975, while its receptor was cloned in 1993.

High Affinity Not in the Vicinity? [PDF]
Functional interactions between the p75 neurotrophin receptor (p75NTR) and the Trk receptors were demonstrated several years ago, but their mechanistic basis remains uncertain. In this issue of Neuron, Wehrman et al. provide a three-dimensional structure

Tyrosine kinase A, C and fibroblast growth factor-2 receptors in bovine embryos cultured in vitro [PDF]
Neurotrophins and basic fibroblast growth factor are ligands of tyrosine kinase receptors, though they bind to different tyrosine kinase receptor classes.

Hypofunctional TrkA Accounts for the Absence of Pain Sensitization in the African Naked Mole-Rat
The naked mole-rat is a subterranean rodent lacking several pain behaviors found in humans, rats, and mice. For example, nerve growth factor (NGF), an important mediator of pain sensitization, fails to produce thermal hyperalgesia in naked mole-rats. The

Receptor tyrosine kinases activate canonical WNT/β-catenin signaling via MAP kinase/LRP6 pathway and direct β-catenin phosphorylation. [PDF]
Receptor tyrosine kinase signaling cooperates with WNT/β-catenin signaling in regulating many biological processes, but the mechanisms of their interaction remain poorly defined.

Multiple Routes for Glutamate Receptor Trafficking: Surface Diffusion and Membrane Traffic Cooperate to Bring Receptors to Synapses [PDF]
Trafficking of glutamate receptors into and out of synapses is critically involved in the plasticity of excitatory synaptic transmission. Endocytosis and exocytosis of receptors have initially been thought to account alone for this trafficking. However, membrane proteins also traffic through surface lateral diffusion in the plasma membrane. We describe

Protein connectivity in chemotaxis receptor complexes [PDF]
The chemotaxis sensory system allows bacteria such as Escherichia coli to swim towards nutrients and away from repellents. The underlying pathway is remarkably sensitive in detecting chemical gradients over a wide range of ambient concentrations. Interactions among receptors, which are predominantly clustered at the cell poles, are crucial to this ...

In vitro effect of nerve growth factor on the main traits of rabbit sperm
Background The nerve growth factor (NGF), a member of the neurotrophins family, plays an important role not only in the nervous but also in other non-nervous systems such as the reproductive system. The aim of the paper is to study the in vitro effect of

Adhesion of membranes via receptor-ligand complexes: Domain formation, binding cooperativity, and active processes [PDF]
Cell membranes interact via anchored receptor and ligand molecules. Central questions on cell adhesion concern the binding affinity of these membrane-anchored molecules, the mechanisms leading to the receptor-ligand domains observed during adhesion, and the role of cytoskeletal and other active processes.
