Q

What is the Pathophysiology of Asthma in kids? (7 steps)

A
  1. Allergen exposure
  2. Dendritic cells present allergen to Th2 type T cells
  3. Th2 type T cells release Cytokines
  4. Cytokines –> Inflamm + Bronchoconstriction
  5. Cytokines activate Humoral immune system
  6. Proliferation of: Mast cells + Eosinophils + Dendritic cells
  7. Mast cells release Histamine
