Abstract
Objective:To investigate the influences of Aβ25-35 on the TLR3 and TLR4 mRNA. Method: NG108-15 cell line was stimulated with Aβ25-35,the supernatant was collected 24 hours later and the inflammatory factors TNF-α and IFN-β were quantitatively measured,the changes in the mRNA expression of TLR3 and TLR4 were detected by real-time PCR. Result:Aβ induced the over-secreting of TNF-α、IFN-β and over-expression of TLR3 and TLR4 mRNA (P 0. 01). Conclusions:Aβ induced the over-secreting of inflammatory factors and over-expression of TLR3 and TLR4,indicating the action of Aβ in causing AD disease might be affiliated with the immune inflammation and the TLRs signaling pathway.
