Overview

Dr. Spurney’s research has focused on the role of G protein coupled receptors (GPCRs) in regulating cellular physiology both in normal and disease states as well as the regulatory mechanisms that modulate GPCR responsiveness at the molecular level. These studies have centered on two major themes. The first investigates the role of GPCR signaling pathways in regulating podocyte function using cultured podocytes and transgenic animals models. The second area of research involves the role of GPCR kinases (GRKs) and arrestin scaffolding proteins in modulating GPCR signaling in bone forming osteoblasts using cultured osteoblast cell lines as well as genetically modified mice including transgenic models and knockout animals. The long-term goal of these studies is to identify novel therapeutic targets that may useful for treating disease processes such as glomerulonephritis and osteoporosis.

Podocyte specific knockout of the natriuretic peptide clearance receptor is podocyte protective in focal segmental glomerulosclerosis.

Journal Article PLoS One · 2025 Natriuretic peptides (NPs) bind to glomerular podocytes and attenuate glomerular injury. The beneficial effects of NPs are negatively regulated by the NP clearance receptor (NPRC), which is highly expressed in podocytes. To determine if inhibiting NPRC is ... Full text Link to item Cite

Blockade of the natriuretic peptide clearance receptor attenuates proteinuria in a mouse model of focal segmental glomerulosclerosis.

Journal Article Physiol Rep · November 2021 Glomerular podocytes play a key role in proteinuric diseases. Accumulating evidence suggests that cGMP signaling has podocyte protective effects. The major source of cGMP generation in podocytes is natriuretic peptides. The natriuretic peptide clearance re ... Full text Link to item Cite
