Rhosin (40 mg/kg; i.p.) treatment prevents social avoidance caused by social defeat stress. Rhosin also blocks sucrose preference deficits induced by defeat in C57Bl6/J (Jackson) mice[3].
Rhosin (30 μM; bilateral, intra- Nucleus Accumbens (NAc) infusions) attenuates stress-induced social avoidance. Rhosin blocks stress-induced hyperexcitability in NAc dopamine 1 receptor medium spiny neurons (D1-MSNs). Rhosin prevents decreased excitatory transmission on NAc D1-MSNs. Rhosin enhances spine density in defeat mice[3].
| Animal Model: | D1-GFP or D2-GFP hemizygote mice on a C57BL/6J background[3] |
| Dosage: | 40 mg/kg |
| Administration: | I.p. |
| Result: | Rhosin was systemically administered 15 min prior to defeat to block RhoA activation. While defeat significantly reduced the time that experimental mice spent interacting with a novel mouse, Rhosin administration suppressed this effect without affecting locomotor behaviors. |
