Asthma Poster

Asthma is one of the most common chronic diseases in the world, affecting over 300 million people. This poster highlights key pathways and new therapies used to treat the condition, including those currently in clinical development.


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.
