The
condition begins with inhalation of
|
|
 |
|
|
|
|
|
allergens ---
animal dander or urinary
|
|
|
proteins.
|
|
|
|
If
these allergens stimulate development of
|
|
 |
|
|
|
|
|
immunoglobulins
(IgE antibodies), a cascade
|
|
of events is
triggered.
|
|
|
|
The
result is the well-known histamine
|
|
 |
|
|
|
|
|
response of
allergy.
