The effect of inflammatory cytokines, tumor necrosis factor-alpha (TNF-a), and IL-1 on asthma is that they increase levels of:
A)norepinephrine, which causes bronchial smooth muscle contraction and mucus secretion.
B)acetylcholine, which causes bronchial smooth muscle contraction and mucus secretion.
C)epinephrine, which causes bronchial smooth muscle contraction and increases capillary permeability.
D)immunoglobulin G, which initiates the complement cascade and causes smooth muscle contraction and increased capillary permeability.
