The thick ascending limb
WebIn the kidney, each nephron segment expresses a distinct pattern of claudins. Cells of the thick ascending limb of Henle's loop (TAL), which is characterized by high paracellular cation permeability, co-express an unusually large number of different claudins: claudin-10, -16, and -19 and, depending on the species, also claudin-3, -4, -8, and/or ...
