Biological Activity for YM 90709
YM 90709 is a novel, selective inhibitor of interleukin-5 (IL-5) (IC50 = 0.45 - 1 mM). Inhibits IL-5-prolonged eosinophil survival and IL-5-induced tyrosine phosphorylation of JAK2 without inhibiting GM-CSF-mediated effects. Inhibits antigen-induced eosinophil and lymphocyte recruitment in rat airways in vivo, without affecting peripheral blood or bone marrow leukocytes.

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.
