Q

(T/F)

The lung is primarily a gas exchange organ that is now being better understood as a mediator of host defense mechanisms.

A

True

note: The lungs are more of a host defense mediator than the skin bc it is directly exposed to the environment through respiration

Q

Discuss the lungs in regards to inflammation:

  • Resolution
  • Repair
A

Resolution: rapid restoration of tissue integrity and function

Repair: complex interplay between humoral (B cells), cellular (T cells), and EM (extracellular matrix) networks

note: the body does this very fast when damage is done to the lungs. There is no time to wait so they start putting down collagen as soon as possible.
e. g. If damage is done to the respiratory membrane, the body doesn’t try to replace the old respiratory membrane w/ a new one (that would take too long). It begins repairing the broken respiratory membrane immediately resulting in a not as good respiratory membrane.

Q

  • Bronchial asthma
    • which type of bronchial asthma occurs due to allergens?

    • Intrinsic (non-atopic): initiated by infections, drugs, pollutants and chemical irritants

Atopic asthma (Allergies):

  • recurrent episodes of wheezing, breathlessness, chest tightness and cough
  • Pathogenesis: type I hypersensitivity via T helper cells (Th2) activation of eosinophils and IgE by cytokines
  • Steps:
    • vascular edema and permeability
    • recruitment of pro-inflammatory cells
    • increased mucus production
    • irreversible airway remodeling
    • eosinophils release mediators
    • more cells recruited
    • epithelial cell death
    • collagen depostion
    • globlet cell hyperplasia

Non-Atopic asthma:

  • Etiology: viral infections of respiratory tract and inhaled pollutants
  • Elicit inflammatory response mediated by eosinophils and IgE
  • Drug-induced asthma (aspirin) and occupational asthma from toxic fumes and wood dust

note: asthma is inflammatory that recruits lots of cells
