1. Peripheral mechanisms of CNS disorders

    I enthusiastically applaud this work for two reasons:

    1) The authors have shown that a systemic mechanism of a brain condition exists and that this may be the best target for a therapeutic intervention. Since most CNS-targeting drugs are difficult to deliver, and given that Kineret and such are large molecular weight protein which do not cross the BBB, the idea that a peripheral IL-1 target may be reached.

    2) The experiments are carefully analyzed and beautifully presented.

    I would like to underscore that we have in the past shown that systemic inflammation is a major player in seizure and psychiatric illness.
