Web15 Jul 2016 · During nephrogenesis, POU domain class 3 transcription factor 3 (POU3F3 aka BRN1) is critically involved in development of distinct nephron segments, including the thick ascending limb of the loop of Henle (TAL). Deficiency of POU3F3 in knock-out mice leads to underdevelopment of the TAL, lack of differentiation of TAL cells, and perinatal death due … WebThe initial segments of the loop of Henle (thin descending and thin ascending limbs) are relatively calcium impermeable. In the thick ascending limb (TAL), ~20% of the filtered calcium is absorbed largely in the cortical segment ( 5 ).

WebThick ascending limb: The main site of sodium recovery in the Henle Loop is the Thick ascending limb (TAL). TAL is water impermeable. In TAL, sodium reuptake works with the NKCC2 transporter in the apical membrane. This transporter transports one sodium ion, one potassium ion, and two chloride ions to the apical edge. Web8 Sep 2024 · The medication inhibits sodium reabsorption through the NKCC2 cotransporter in the thick ascending limb of the loop of Henle ( TAL ), leading to significant diuresis. Careful monitoring is important because loop diuretics result in increased excretion of sodium, potassium, chloride, calcium, magnesium, and water. david wright invoice
