Levels of PLCγ, a phospholipase C (PLC) isozyme, were significantly increased in the cytosol in the injured left cortex (LC) at 5, 30 and 120 min after brain injury. In the same site, although levels of membrane PLC γ did not alter at 5 and 30 min, they were found to be decreased at 2 h after brain injury. In general, the levels of both cytosolic and membrane PLC γ were unaltered in the contralateral right cortex (RC), ipsilateral left hippocampus (LH) and contralateral right hippocampus (RH) between 5 and 120 min after brain injury. These results suggest that, in addition to well- proposed excitatory neurotransmitter-receptor systems, increased levels of P LC γ may also contribute to alterations in PIP2 signal transduction pathway, particularly in the greatest injury site (LC) after lateral EP brain injury.
