  • Title: Elevated platelet phosphatidylinositol bisphosphate in mediated schizophrenics.
    Author: Das I, Essali MA, de Belleroche J, Hirsch SR.
    Journal: Schizophr Res; 1994 Jun; 12(3):265-8. PubMed ID: 7914431.
    Abstract:
    Levels of phosphatidyl inositol 4,5-bisphosphate (PIP2) have been measured in platelets from schizophrenic and healthy subjects by means of an immunoassay. Resting platelets from schizophrenic patients contained a significantly increased amount of PIP2 compared to controls. The agonist-stimulated hydrolysis of PIP2 in platelets from the schizophrenic group was also significantly greater than that in platelets from the control group. PIP2 plays an important role in cell signalling, and the observed abnormality may be reflected by an impairment in signal transduction via the inositol phospholipid pathway.
