A

-HDAC activation (histone deacetylase)
-enhanced apoptosis of inflammatory cells

52

mechanism of mast cell degranulation requires what 4 things?

A
  1. binding of IgE antibodies to Fc epsilon receptor
  2. binding of antigen to IgE antibodies
  3. clustering of Fc epsilon receptors
  4. influx of Ca2+ via Ca2+ release activated channels (CRAC)
53

59
Q

remodeling in COPD (4)

A

-fibrosis of small airways
-hyperinflation of lungs: alveolar enlargement and alveolar wall destruction
-mucus hypersecretion

60
Q

what is the function of elastase?

A

elastase breaks down elastin, which is a needed structural component of lung tissue. Alpha1- antitrypsin normally protects the lung from elastase

Q

how does N-acetylcysteine (Mucomyst) work for CF?

A

it opens disulfide linkages in mucus thereby lowering the viscosity

67
Q

true or false: dehydration of ASL (airway surface lipid) causes thickening of mucus

68
