Nicotinic ACh Receptors Scientific Review
Updated in 2014, this review by Sue Wonnacott summarizes the diverse structure and function of nicotinic acetylcholine receptors and gives an in-depth review of the ligands available for nAChR research. Compounds available from Tocris are listed.
Pain Poster
Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
