Abstract :

Objectives: Substance P has been documented to attenuate the activity of PPAR-γ and is involved in neurogenic inflammation. Thus, the present study has been designed to investigate: effect of aprepitant, NK1 receptor antagonist, in vascular dementia (VaD) and downstream possible involvement of PPAR-γ shall also be investigated in bilateral carotid artery occlusion (BCCAO) induced vascular dementia. Methods: BCCAO was done in male wistar rats to induce VaD. VaD was assessed in terms of impairment of learning and memory (Morris water maze (MWM) & Object recognition test (ORT)), increased acetylcholinesterase (AChE) activity, oxidative stress (TBARS, Nitrite level), tumor necrosis factor-alpha (TNF- α) level and decreased reduced glutathione (GSH) level. Key findings: Administration of aprepitant for 2 weeks significantly improved learning and memory in terms of mean escape latency time & time spent in target quadrant in MWM and time spent to explore objects in ORT in demented rats. Aprepitant also reduced AChE activity, TBARS, TNF-α, nitrite and increased GSH level. Administration of BADGE (PPAR-γ antagonist) (30mg/kg/day, i.p\) with aprepitant (40mg/kg/day,i.p.) significantly reduced the protective effect of aprepitant that shows protective effect of aprepitant is PPAR-γ dependent. Conclusion: Thus, it can be concluded that aprepitant attenuates vascular dementia in PPAR-γ dependent manner.
