Cargo binding promotes KDEL receptor clustering at the mammalian cell surface [PDF]
Sci. Rep. 6, 28940, 2016, 2017 Transmembrane receptor clustering is a ubiquitous phenomenon in pro- and eukaryotic cells to physically sense receptor/ligand interactions and subsequently translate an exogenous signal into a cellular response. Despite that receptor cluster formation has been described for a wide variety of receptors, ranging from chemotactic receptors in bacteria to ...

Polar Chemoreceptor Clustering by Coupled Trimers of Dimers [PDF]
Biophys J 96(2): 453-463 (2009), 2009 Receptors of bacterial chemotaxis form clusters at the cell poles, where clusters act as "antennas" to amplify small changes in ligand concentration. Interestingly, chemoreceptors cluster at multiple length scales. At the smallest scale, receptors form dimers, which assemble into stable timers of dimers.

Detection in Molecular Communications with Ligand Receptors under Molecular Interference [PDF]
arXiv, 2020 Molecular Communications (MC) is a bio-inspired communication technique that uses molecules to transfer information among bio-nano devices. In this paper, we focus on the detection problem for biological MC receivers employing ligand receptors to infer the transmitted messages encoded into the concentration of molecules, i.e., ligands.

Formation and Stability of Synaptic Receptor Domains [PDF]
Phys. Rev. Lett. 106, 238104 (2011), 2010 Neurotransmitter receptor molecules, concentrated in postsynaptic domains along with scaffold and a number of other molecules, are key regulators of signal transmission across synapses. Employing experiment and theory, we develop a quantitative description of synaptic receptor domains in terms of a reaction-diffusion model.

Purinergic receptors in neurogenic processes
Brain Research Bulletin, 2019 Neurogenesis is a process of generating functional neurons, which occurs during embryonic and adult stages in mammals. While neurogenesis during development phase is characterized by intensive proliferation activity in all regions of the brain to form the architecture and neural function of the nervous system, adult neurogenesis occurs with less ...

Purinergic signalling: past, present and future
Brazilian Journal of Medical and Biological Research, 2009 The discovery of non-adrenergic, non-cholinergic neurotransmission in the gut and bladder in the early 1960's is described as well as the identification of adenosine 5'-triphosphate (ATP) as a transmitter in these nerves in the early 1970's.

ATP Hysteresis in Tripartite Synapses [PDF]
arXiv, 2009 Recent experimental studies strongly suggest the influence of glial purinergic transmission in the modulation of synaptic dynamics. By releasing adenosine triphosphate (ATP), which accumulates as adenosine, astrocytes tonically suppressed synaptic transmission. The delayed multi-step feedback of the glial adenosine with the neuron suggest the existence

Nature Communications, 2020 P2X7 receptors are purinergic receptors with pro-inflammatory functions. Here, the authors show that inhibition of leukocyte P2X7 receptors reduces dendritic spine pathology and social behavioral deficits in a mouse model of Rett syndrome.

Structure and dynamics of dynorphin peptide and its receptor [PDF]
arXiv, 2019 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.
