This figure summarizes current knowledge regarding the ligands and sites of expression for GPR41, GPR43, GPR109A, OLFR78, and OLFR558. In addition, cardiovascular phenotypes in KO mice are outlined. Gpr41 KO mice exhibit increased SBP103, with higher pulse pressure, end-diastolic pressure (DP), tau, and perivascular fibrosis108. Gpr43 KO mice have an increased heart/body weight, pulse pressure, and perivascular fibrosis108. Gpr109a KO mice are reported to have a higher pulse pressure, end-DP, as well as perivascular fibrosis108. Olfr78 KO mice have a lower plasma renin activity39,49.
