GPCR and purine signaling

G protein-coupled receptors regulate a plethora of physiological processes. Moreover, these receptors and their ligands are the targets for the majority of currently approved pharmaceuticals. We investigate GPCRs, their ligands and the associated signal transduction cascades primarily in the context of energy homeostasis, metabolism and the cardiovascular system.

In the picture above one can see immunocytochemical staining of primary murine white pre-adipocytes detected with a primary antibody against Gpr81 and a secondary antibody labelled with Alexa Fluor 647.
