Type III Hypersensitivity

Formation of immune complexes that accumulate and cause inflammatory reactions.

Antigens involved can be endogenous or instead exogenously sourced, that is, representing an autoimmune disease or instead due to exposure to foreign materials.

Examples of resulting diseases are systemic lupus erythematosus, which is an autoimmune disease, and serum sickness, which is caused by exposure to serum sourced from different species, such as horse serum as a source antiserum/antitoxin, which can be used to treat diphtheria infections.
