The photographs on the cover show a series of studies on neural mechanisms for sodium (Na) homeostasis in animals.
Na homeostasis is essential to life, and Na+ concentrations ([Na+]) in plasma and cerebrospinal fluid (CSF) arecontinuously monitored in the brain by Nax, an extracellular [Na+] sensitive Na channel, to control salt-intake behaviors.
Nax is expressed in glial cells in the circumventricular organs (e.g. subfornical organ [SFO]), which lack a blood-brain
barrier. Previous in vitro studies indicated that an apparent threshold value of Nax for [Na+] is ~150 mM, though [Na+] inplasma and CSF is strictly controlled at 135–145 mM in mammals. This discrepancy has now been resolved by our study
which showed that the [Na+] dependency of Nax is shifted to the lower-concentration side by endothelin-3 produced in
the SFO in response to dehydration (Hiyama et al., Cell Metab., 2013). See page 35 of this report for details.
