Alzheimer's Poster
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.
Cancer Metabolism Poster
Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the main targets for cancer metabolism researchers. Genetic changes and epigenetic modifications in cancer cells alter the regulation of cellular metabolic pathways. These distinct metabolic circuits could provide viable cancer therapeutic targets.
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.
Huntington's Disease PosterUpdated
Huntington's disease (HD) is a severe monogenic neurodegenerative disorder, which is characterized by the prevalent loss of GABAergic medium spiny neurons (MSN) in the striatum. This poster summarizes the effects of mutant huntingtin aggregation implicated in the pathology of HD, as well as highlighting the use of iPSCs for HD modeling.
