Molecole coinvolte nella regolazione ionica in due specie di anfiosso provenienti da mari diversi

. Abstract Molecules involved in ionic regulation in two species of lancelets from different seas. The presence of two molecules involved in osmoregulation and pH control (NHE and NKA) was demonstrated by immunocytochemical studies in Branchiostoma lanceolatum and B. floridae, coming from the Mediterranean Sea and Atlantic Ocean, respectively. The different pattern of immunoreactivity to these molecules in the two species of lancelets was discussed and correlated to the variability of chemical-physical parameters of the two seas of origin.
