A recent upsurge of research examining inositol phospholipids (IP)—membrane-bound species fundamental to cell signaling—continues underscore the role of this pathway in both normal and disease-associated cellular physiology.  This volume includes a selection of cutting-edge, multidisciplinary reports borne out of the conference “Inositol Phospholipid Signaling in Physiology and Disease” held June 26–27, 2012 at the New York Academy of Sciences in New York City.  Papers include important developments investigating IP signaling in immunology, cancer, inflammation, and metabolic disorders.
