Problem:We tested here the impact of a long-term inhibition of dipeptidyl peptidase-4 (DPP-4) with sitagliptin on the deposition of amyloid-beta within the brain and deficits in memory-related behavioral paradigms in a model of Alzheimer's disease (AD): double transgenic mice B6*Cg-Tg(APPswe,PSEN1dE9)85Dbo/J. Mice began to receive sitagliptin at 7 months of age. Three different dose of sitagliptin (5, 10 and 20 mg/kg), were administered daily for 12 weeks by gastric gavage. The treatments counteracted: (i) the memory impairment in the contextual fear conditioning test; (ii) increased the brain levels of GLP-1; (iii) produced significant reductions of nitrosative stress and inflammation hallmarks within the brain, as well as (iv) a significant diminution in the ultimate number and total area of betaAPP and Abeta deposits. All these effects much more evident for the dose of 20 mg/kg sitagliptin. The long-term inhibition of the endogenous DPP-4 enzymes with sitagliptin can significantly delay some forms of AD pathology, including amyloid deposition, when administered early in the disease course of a transgenic mouse model of AD.
Solution:
Long-term inhibition of dipeptidyl peptidase-4 in Alzheimer's prone mice.
