Implication
Preclinical mapping in primates warrants no clinical changes yet; extends cell type-specific natriuretic peptide receptor distribution data.
Key Points
- Determine the anatomical and cell-type-specific distribution of mRNA expression for three homologous natriuretic peptide receptors (ANPRA, ANPRB, and ANPRC) across primate tissues.
- Analyzed ANPRA, ANPRB, and ANPRC mRNA expression across multiple rhesus monkey tissues using in situ hybridization.
- ANPRA mRNA is abundantly expressed in the renal glomerulus, adrenal zona glomerulosa, pituitary, cerebellum, and endocardial endothelial cells of the atria and right ventricle.
- ANPRB mRNA expression is predominantly restricted to the adrenal medulla, pituitary, and cerebellum.
- ANPRC mRNA shows a divergent distribution, localizing to endocardial endothelial cells across all four cardiac chambers and throughout the myocardium exclusively in the right atrium.
