| Research Abstract |
In the present study, we have aimed to clarify the connection between the Small protein encoded by the Intermediate stage Transcript of HHV-6 (SITH)-1 and mood disorders. SITH-1 significantly up-regulated the intracellular calcium levels. An increase in calcium levels is generally thought to be an important factor in mood disorders. When we caused SITH-1 to be expressed in mouse brain glial cells, the mouse showed manic-like behavior and depressive-like behavior. These results suggest that SITH-1 is involved in the onset of mood disorders.
