报告主要内容:

Neuroinflammation is a critical step in neurodegeneration and consequently contributes to many diseases such as Alzheimer’s disease.The present research started with the design of a negative control.  A negative control is to be used in a large number of experiments. It turns out that this negative control (AFT1) had an off target which was not observed with the positive control (probe).The negative control was able to modify the activity of g-secretase leading to an increase of potentially neurotoxic peptides. Structurally analogues of AFT1 were prepared and tested.  Several of these compounds were found to be more potent than AFT1 in the formation of neurotoxic peptides.At this stage, one could wonder whether AFTs could induce cognitive disorders following prolonged administration in animals.Mice were treated with an AFT. The product appeared to be distributed in the brain and, in contrast to the previous hypothesis, was able to rescue cognitive deficits associated with aging.The mechanism of action of this family of compounds has been investigated and will be discussed.
