Biological Activity

Cooling agent that activates the novel cold receptors TRPM8 (CMR1) and TRPA1 (ANKTM1/TRPN1), members of the TRP ion channel family. Induces currents in CMR1-expressing HEK 293 cells (EC50 = 0.36 μM) more potently than menthol or low temperatures. Produces "wet shakes" in vivo.

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.
