Phosphate absorption by Aplysia californica gut: thyroid hormone stimulation.
Mucosal membranes of foregut epithelia of Aplysia californica contain a sodium/phosphate symporter. Triiodothyronine stimulated the absorptive activity of the sodium/phosphate symporter, whereas reverse triiodothyronine had no effect on the sodium/phosphate symporter. It appears that thyroid hormone or its molluscan equivalent plays a role in the overall regulation of phosphate homeostasis by the Aplysia californica gut.
