Description

Three distinct roles of aquaporin-4 in brain function revealed by knockout mice, 2006

AQP4 is involved in cerebral water balance, astrocyte migration, and neural signal transduction.

We found that AQP4-overexpression is likely triggered by hypoxia
Immunization of mice with a peptide derived from the HTLV-1 TAX1BP1 protein induces cross-reactive antibodies against aquaporin 4.
Inhibition of NMDA Receptors Downregulates Astrocytic AQP4
AQP4 is able to induce an autoreactive T cell response

In contrast, central hypothyroidism associated with infection may be due to upregulation of type 2 deiodinase activity in tanycytes, specialized glial cells that line the infralateral walls and floor of the third ventricle.
