Voltage-sensitive Ca2+ channels that control neurotransmitter release are blocked by omega-conotoxin (omega-CgTx) GVIA from the marine snail Conus geographus, the most widely used inhibitor of neurotransmitter release. However, many mammalian synapses are omega-CgTx-GVIA insensitive. We describe a new Conus peptide

In larval lamprey, hemitransections were performed on the right side of the rostral spinal cord to axotomize ipsilateral reticulospinal (RS) neurons. First, at short recovery times (2-3 weeks), uninjured RS neurons contralateral to hemitransections fired a smooth train of action

Numerous laboratory-based data have shown the ability of toluene (Tol) to exacerbate noise-induced hearing loss. However, the mechanism responsible for the synergistic effects of a coexposure to noise and Tol has not yet been completely elucidated. Recent investigations in rats

Gabapentin (Neurontin) has been successfully used in the treatment of both epilepsy and neuropathic pain. Despite its widespread clinical use, its mechanism of action is very poorly understood. Indeed, the only protein it is known to interact with is the

A New Binding Method (NBM) was used to investigate the characteristics of the specific binding of 125I-omega-conotoxin (omega-CTX) GVIA and 125I-omega-CTX MVIIC to Cav2.1 and Cav2.2 channels captured from chick brain membranes by antibodies against B1Nt (a peptide sequence in
