In insects, γ-aminobutyric acid (GABA) is the major inhibitory neurotransmitter, and GABA-gated ion channels are the target of different classes of insecticides, including fipronil. We …

Molecular biology of the blood-brain and the blood-cerebrospinal fluid barriers: similarities and differences.

Fluids and barriers of the CNS

Redzic Z.
PMID: 21349151
Fluids Barriers CNS. 2011 Jan 18;8(1):3. doi: 10.1186/2045-8118-8-3.

Efficient processing of information by the central nervous system (CNS) represents an important evolutionary advantage. Thus, homeostatic mechanisms have developed that provide appropriate circumstances for neuronal signaling, including a highly controlled and stable microenvironment. To provide such a milieu...

Regulation of thermoTRPs by lipids.

Temperature (Austin, Tex.)

Morales-Lázaro SL, Lemus L, Rosenbaum T.
PMID: 28349093
Temperature (Austin). 2016 Nov 01;4(1):24-40. doi: 10.1080/23328940.2016.1254136. eCollection 2017.

The family of Transient Receptor Potential (TRP) ion channels is constituted by 7 subfamilies among which are those that respond to temperature, the thermoTRPs. These channels are versatile molecules of a polymodal nature that have been shown to be...

Pharmacological characterization of venoms from three theraphosid spiders: Poecilotheria regalis, Ceratogyrus darlingi and Brachypelma epicureanum.

BACKGROUND: Tarantulas (Theraphosidae) represent an important source of novel biologically active compounds that target a variety of ion channels and cell receptors in both insects and mammals. In this study, we evaluate and compare the pharmacological activity of venoms...

Biocrystallography in Switzerland: Achievements and Future Perspectives.

Chimia

Grütter MG.
PMID: 28982439
Chimia (Aarau). 2014 Feb 26;68(1):54-59. doi: 10.2533/chimia.2014.54.

The first protein crystallography group in Switzerland was installed at the Biozentrum of the University of Basel approximately 40 years ago. Since then protein crystallography has grown and matured remarkably and is now established in the molecular biology, biochemistry...

Frontiers in physiology

Dimitrova A, Walko M, Hashemi Shabestari M, Kumar P, Huber M, Kocer A.
PMID: 27708587
Front Physiol. 2016 Sep 21;7:409. doi: 10.3389/fphys.2016.00409. eCollection 2016.

Understanding the functioning of ion channels, as well as utilizing their properties for biochemical applications requires control over channel activity. Herein we report a reversible control over the functioning of a mechanosensitive ion channel by interfering with its interaction...

CXCL12-induced neurotoxicity critically depends on NMDA receptor-gated and L-type Ca.

Journal of neuroinflammation

Sanchez AB, Medders KE, Maung R, Sánchez-Pavón P, Ojeda-Juárez D, Kaul M.

J Neuroinflammation. 2016 Sep 23;13(1):252. doi: 10.1186/s12974-016-0724-2.

BACKGROUND: The chemokine receptor CXCR4 (CD184) and its natural ligand CXCL12 contribute to many physiological processes, including decisions about cell death and survival in the central nervous system. In addition, CXCR4 is a co-receptor for human immunodeficiency virus (HIV)-1...

Synthesis of Phenylene Vinylene Macrocycles through Acyclic Diene Metathesis Macrocyclization and Their Aggregation Behavior.

Chemistry (Weinheim an der Bergstrasse, Germany)

Zhang C, Yu C, Long H, Denman RJ, Jin Y, Zhang W.
PMID: 26420443
Chemistry. 2015 Nov 16;21(47):16935-40. doi: 10.1002/chem.201502848. Epub 2015 Sep 30.

A series of phenylene vinylene macrocycles (PVMs) bearing substituents with various sizes and electronic properties have been synthesized through a one-step acyclic diene metathesis macrocyclization approach and their aggregation behaviors have been investigated. In great contrast to the aggregation...

Microdomain-specific localization of functional ion channels in cardiomyocytes: an emerging concept of local regulation and remodelling.

Biophysical reviews

Balycheva M, Faggian G, Glukhov AV, Gorelik J.
PMID: 28509981

Cardiac excitation involves the generation of action potential by individual cells and the subsequent conduction of the action potential from cell to cell through intercellular gap junctions. Excitation of the cellular membrane results in opening of the voltage-gated L-type...

Targeting Ion Channels: An Important Therapeutic Implication in Gastrointestinal Dysmotility in Patients With Spinal Cord Injury.

Journal of neurogastroenterology and motility
