Single-cell analysis identifies the CNP/GC-B/cGMP axis as marker and regulator of modulated VSMCs in atherosclerosis by Moritz Lehners, Hannes Schmidt, Maria T. K. Zaldivia, Daniel Stehle, Michael Krämer, Andreas Peter, Julia Adler, Robert Lukowski, Susanne Feil, Robert Feil

“…Silencing of the CNP/GC-B axis in VSMCs results in an increase of chondrocyte-like plaque cells. These findings indicate that the CNP/GC-B/cGMP pathway is a marker and atheroprotective regulator of modulated VSMCs, limiting their transition to chondrocyte-like cells. …”
