Cardiovascular Poster

Cardiovascular disease remains one of the major causes of morbidity and mortality in the Western world and therefore this therapeutic area continues to be of great interest to researchers. This poster highlights the key GPCRs regulating vascular reactivity.


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.
