G-protein signaling group (Wettschureck group)

Group leader: Nina Wettschureck

Technical assistant: Martina Finkbeiner

Our group studies all aspects of cell communication in the vessel wall, for example the regulation of leukocyte/endothelial interactions, the interplay between endothelial cells and smooth muscle cells, and the communication between vascular cells and stromal/parenchymal cells. Most of our projects focus on the large family of G-protein-coupled receptors (GPCRs), which mediate the intracellular effects of numerous hormones, neurotransmitters, or local mediators. In the past, we identified new functions for GPCRs and their effector families G12/13 and Gq/11 in the cardiovascular, endocrine, and immune system (for example Herroeder et al., Immunity 2009; Sassmann et al., J Clin Invest 2010; Takefuji et al., Circulation 2012; Takefuji et al., J Exp Med 2013; Sivaraj et al., Dev Cell 2013; Chen et al., J Clin Invest 2014; Kaur et al., Circ Res 2016). More recently, we focus on orphan GPCRs, i.e., GPCRs with yet unknown endogenous ligand and function. To better understand the biological function of these enigmatic GPCRs, we performed single-cell expression analyses in primary murine vascular and immune cells (Kaur et al., Nat Commun 2017; Tischner et al., JCI Insight 2017) and identified rare cell populations with specific GPCR repertoires. Based on these data, we are currently analyzing the function of orphan GPCRs in specialized subpopulations of smooth muscle (Carvalho et al., Circulation 2020), endothelial cells and immune cells (Gurusamy et al., Nat Commun 2021, accepted). Other projects address the role of angiocrine factors in cardiac remodeling or the regulation of leukocyte/endothelial interactions.
