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.

Engineering antibodies with cancer‐associated binding sites
BMEMat, EarlyView.This review describes antibodies that perform direct/indirect roles in cancer treatment by binding to effective targets and discusses how antibodies kill tumors and modulate tumor microenvironment through these targets. The classification of expression systems for antibody production is summarized to guide appropriate selection based on different ...

Transmembrane Peptides as Inhibitors of ErbB Receptor Signaling [PDF]
Molecular Biology of the Cell, 2004 Receptor tyrosine kinases have a single transmembrane (TM) segment that is usually assumed to play a passive role in ligand-induced dimerization and activation of the receptor. However, mutations within some of these receptors, and recent studies with the epidermal growth factor (EGF) and ErbB2 receptors have indicated that interactions between TM ...

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.

Sistema Neuregulina1/ErbB: importância no controlo da função cardíaca.
Acta Médica Portuguesa, 2011 The family of Neuregulins (NRG), growth factors like epidermal growth factor, is known to induce growth and differentiation of epithelial, glial, neuronal, and skeletal muscle cells. This family comprises four members, being NRG1 the most largely studied,

Transactivation of ErbB Family of Receptor Tyrosine Kinases Is Inhibited by Angiotensin-(1-7) via Its Mas Receptor. [PDF]
PLoS ONE, 2015 Transactivation of the epidermal growth factor receptor (EGFR or ErbB) family members, namely EGFR and ErbB2, appears important in the development of diabetes-induced vascular dysfunction.

European Journal of Heart Failure, EarlyView.New anticancer therapies with potential cardiovascular side effects are continuously being introduced into clinical practice, with new and often unexpected toxicities becoming apparent only after clinical introduction. These unknown toxicities should be identified and understood beforehand to better prepare patients and physicians, enabling the ...

Chronic morphine treatment attenuates cell growth of human BT474 breast cancer cells by rearrangement of the ErbB signalling network. [PDF]
PLoS ONE, 2013 There is increasing evidence that opioid analgesics may interfere with tumour growth. It is currently thought that these effects are mediated by transactivation of receptor tyrosine kinase (RTK)-controlled ERK1/2 and Akt signalling.

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.
