Allergic Mechanism

[Terry Boyd]

Hi!  I'm a high-school biology student doing a term paper
on allergies, specifically allergy to urea-formaldehyde.  I just
haven't been able to find one key point in my research:  Why, once
stimulated by IgE and an allergen, do mast cells release the contents
of their granules into the environment?
	If anybody can offer any advice in this respect, or has
dealt or suffered with this allergy, I'd appreciate anything you can
tell me.  Thanks!
