The active zone is a specialized region of the presynaptic plasma membrane where the neurotransmitter release occurs by exocytosis. Mast cells also release inflammatory mediators by exocytosis resulting in induction of allergic responses. In our previous reports, we found that active zone proteins, Munc13-1 and ELKS regulates exocytosis of mast cell positively.

These data suggest that a similar molecular mechanism operates in both systems. However, mast and neuronal cells are structurally very different; an active zone is found in neuronal cells.

Fifteen patients were enrolled. The dose for S-1 was set at 80 mg/m2/day (days 1-14), while the dose for paclitaxel increased by 10 mg/m2 for every three patients, with a starting dose of 100 mg/m2 and was given biweekly on day 1 and 15.
