The [[immune response]] is most often initiated by exposure to thermophilic [[actinomycete]]s, which generates [[IgG]]-type [[antibodies]] that circulate in the bloodstream. Following a subsequent exposure, IgG antibodies combine with the inhaled [[allergen]] and form [[immune complex]]es. These complexes are deposited in the lung and generate an inflammatory response typical of a [[type III hypersensitivity]] response. Farmer's lung is an example of extrinsic allergic alveolitis. {{Respiratory pathology}} {{Allergic conditions}} [[Category:Pulmonology]] {{disease-stub}} [[de:Farmerlunge]] [[sl:Farmarska pljuča]]
