Scholarcy highlights

  • The effects of 3,5′,3′-triiodo-l-thyronine, alone or combined with cortisol, on the physiological properties of cultured pavement cell epithelia from freshwater rainbow trout gills were assessed
  • Under symmetrical culture conditions, T3 had no effect on transepithelial Na+ and Cl− transport, which was passive
  • Hormone treatment did not change the pattern of ion movement
  • These experiments demonstrate that cultured pavement cell epithelia from freshwater rainbow trout are T3-responsive and provide evidence for the direct action of T3 and the interaction of T3 and cortisol on the physiology of this preparation
