近年来的研究证明,一些同血钙调节无关的组织和细胞也含有具有生物效应的1,25-二羟维生素 D_3受体,提示 DHCC 具有内分泌外功能。经典的 DHCC 内分泌系统DHCC 调节钙平衡的系统是经典内分泌系统。机制是低血钙通过甲状旁腺激素促进肾合成 DHCC;钙磷浓度变化也能直接影响其合成。DHCC 再通过上段小肠粘膜细胞的激素受
Recent studies have shown that some tissues and cells not related to calcium regulation also contain biologically active 1,25-dihydroxyvitamin D3 receptors, suggesting that DHCC has endocrine and extra-inferior functions. The classical DHCC endocrine system DHCC regulates the calcium homeostasis system is a classical endocrine system. The mechanism is that hypocalcemia promotes renal synthesis of DHCC via parathyroid hormone; changes in calcium and phosphorus concentrations can also directly affect its synthesis. DHCC passes through the upper intestinal mucosal cell hormones
