TRC: Allergic asthma

Allergic asthma

Allergic asthma consists of inflammation and hyper-responsiveness. Components of the inflammation (inflammatory cells, edema, mucus) are shown along with the muscle hypertrophy and contraction which push the swollen tissue into the lumen, which gets smaller and smaller.

The mast cells in an acute allergic asthma attack are found to have released their granular contents.

Extra info: Some degranulated mast cells are always found in an allergic asthmatic patient's lungs. However, in an acute attack, most of the mast cells present will be found to have released their granular contents.

Released granules can produce immediate bronchospasm.

Extra info: The release granules cause immediate bronchospasm, but also can stimulate other cytokines that are responsible for late inflammatory reactions.
