Intestinal Phosphate Absorption System (N/A)

Target
N/A
Molecular classification
Physiological System, Transporter system, Enzymatic regulation of transport
01

Overview

The intestinal phosphate absorption system encompasses the pathways and regulatory mechanisms involved in the uptake of dietary phosphate in the small intestine. It relies on both active (transcellular) and passive (paracellular) transport, mediated by transporters like NaPi2b (SLC34A2) and influenced by factors like NHE3. Hormones such as vitamin D, PTH, and FGF23 tightly regulate this system to maintain phosphate homeostasis. While targeted for treating hypophosphatemia and other conditions, dysregulation can lead to hyperphosphatemia and related complications.
