Glomerular function (GFR)

Glomerular function refers to the physiological process by which the renal glomeruli filter blood to produce an ultrafiltrate, which eventually becomes urine. This process is essential for maintaining systemic homeostasis by removing metabolic waste products like urea and creatinine while regulating the body's fluid volume, electrolyte balance, and acid-base status (Source: StatPearls [PMID: 30725841]). Glomerular function is not a single molecular target, such as a protein or receptor, but rather a complex multi-cellular physiological operation involving the glomerular filtration barrier, which consists of the vascular endothelium, the glomerular basement membrane, and podocyte epithelial cells (Source: NIDDK). In clinical medicine and pharmacology, glomerular function is quantified by the Glomerular Filtration Rate (GFR), which is a key biomarker for diagnosing and monitoring Chronic Kidney Disease (CKD) and Acute Kidney Injury (AKI). Although many therapeutic agents—including ACE inhibitors, Angiotensin II Receptor Blockers, and SGLT2 inhibitors—are used to protect or modify glomerular function, they do so by acting on specific molecular targets like enzymes or transporters rather than the filtration process itself (Source: PubMed [PMID: 33734000]).

Glomerular function is not a molecular target; however, drugs modulate it by altering glomerular hemodynamics, reducing intraglomerular pressure through the inhibition of the renin-angiotensin-aldosterone system (RAAS), or inhibiting tubular-glomerular feedback via SGLT2 blockade (Source: PubMed [PMID: 33734000]).
