TC 2559 difumarate
Subtype-selective partial agonist for α4β2 nicotinic acetylcholine receptors (EC50 values are 0.18, 12.5, 14.0, > 30, > 100 and > 100 μM for α4β2, α4β4, α2β4, α3β4, α3β2 and α7 receptor subtypes respectively). Displays selectivity for (α4)2(β2)3 receptor stoichiometry and enhanced CNS-PNS selectivity ratio. Attenuates scopolamine-induced cognitive deficits in a step-through passive avoidance task.

Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia, affecting approximately 47 million people worldwide. Updated in 2015, this poster summarizes the structural and functional changes observed in the progression of this neurodegenerative disease, as well as classic AD drug targets.
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.
