Abstract

Background. Translocator protein 18 kDa (TSPO) plays a key role both in microglial activation and neuroinflammation. Postoperative cognitive decline (POCD), a notable hazard to both patients and society, maybe contribute to deficiently controlled neuroinflammatory processes initiated by anesthesia and surgery. So far it is unclear that whether TSPO is involved in the pathogenesis of POCD or not. Materials and Methods. Twelve adult rats and twelve aged rats were divided into control and isoflurane groups respectively. POCD was induced by a 4-hour exposure of 2% isoflurane. The memory retention capability was assessed by the Morris water maze trial, the mRNA and the protein expression of both TSPO and Iba1 were assessed by real-time quantitative PCR and Western Blot analysis separately. Results. Compared to the control group, the latency time to find platform was longer in the groups exposed to isoflurane (p<0.05); the mRNA and the protein expression of both TSPO and Iba1 were correspondingly upregulated (p<0.05); especially that the severity of cognitive decline and the degree of TSPO and Iba1 over-expression were significantly different between the adult and aged rats (p<0.05); The twice times across the platform showed no significant difference among all the groups. Conclusions. Our study for the first time showed that TSPO may be involved in the pathogenesis of the cognitive decline induced by isoflurane anesthesia. Its role for being a biomarker and an interventional target of POCD deserves future investigation.
