Ion channels are a key target class for the pharmaceutical industry and available drugs that target ion channels combine clinical benefit with commercial success. Primary research is continuously uncovering potential new ion channel targets in virtually all possible disease indications, including numerous neurological disorders. This trend is expected to continue for a long time to come: ion channels are at the center of Read More

Ion channels are at present the third biggest target class in drug discovery. Primary research is continually uncovering potential new ion channel targets in indications such as cancer, diabetes and respiratory diseases, as well as the more established fields of pain, cardiovascular disease, and neurological disorders. Despite the physiological significance and therapeutic relevance in a wide variety of biological systems, ion chan Read More

Disorders of the central nervous system (CNS) are complex disease states that represent a major challenge for modern medicine. Although aetilogy is often unknown, it is established that multiple factors such as defects in genetics and/or epigenetics, the environment as well as imbalance in neurotransmitter receptor systems are all at play in determining an individual's susceptibility to disease. Gene therapy is cu Read More

Voltage-gated sodium channels play an essential biophysical role in many excitable cells such as neurons. They transmit electrical signals through action potential (AP) generation and propagation in the peripheral (PNS) and central nervous systems (CNS). Each sodium channel is formed by one α-subunit and one or more β-subunits. There is growing evidence indicating that mutations, changes in expression, or inappropriate mo Read More

Over the last couple of years, transient receptor potential vanilloid 1(TRPV1) channels have been a hot topic in ion channel research. Since this research field is still rather new, there is not much known about the working mechanism of TRPV1 and its ligands. Nevertheless, the important physiological role and therapeutic potential are promising. Therefore, extensive research is going on and a lot of natural as well as synth Read More

Ion channels are integral membrane proteins that enable the passive flow of inorganic ions by forming hydrated pores across biological membranes. Their pore-forming alpha subunits determine ion permeation and provide the machinery for gating. In addition, channel class specific accessory proteins termed beta, gamma and delta subunits have been found that modulate or even determine key properties like chan Read More

Neurodegenerative diseases are characterised by a net loss of neurons from specific regions of the central nervous system (CNS). Until recently, research has focused on identifying mechanisms that lead to neurodegeneration, while therapeutic approaches have been primarily targeted to prevent neuronal loss. This has had limited success and marketed pharmaceuticals do not have dramatic benefits. Here we suggest that Read More

GABA, acting via GABAA receptors, is well-accepted as the main inhibitory neurotransmitter of the mature brain, where it dampens neuronal excitability. The receptor's properties have been studied extensively, yielding important information about its structure, pharmacology, and regulation that are summarized in this review. Several GABAergic drugs have been commonly used as anesthetics, sedatives, and antico Read More
