Because Minocycline may inhibit members of the caspase family, the MAP kinase pathway and NOS (which play central role in the neuroprotective effects of Minocycline in different model of brain-disease), we would like to test the neuroprotective effect of Minocycline in the early development (i.e.- at the first psychotic episode) of schizophrenia. The safety record of Minocycline and its ability to penetrate the blood-brain barrier are well known. Therefore, if this drug will be found to have neuroprotective effect in schizophrenia it may be a novel therapy.
