What happens in immune complex reactions? | Ag/Ab complexes form in fluid phase of tissues or blood and assume unique biologic functions such as interactions with complement or cellular receptors |
What are some examples of immune complex (Type III) reactions? | Arthus reactionSerum sicknessSome autoimmune disease such as glomerulonephritis in SLE |
What happens when Ab reacts with soluble Ag in circulation? | The formation of complexes that may disseminate and lodge in any tissue with large filtration area and cause lesion of immune complex disease. |
What happens when there is a formation of complexes that may disseminate and lodge in any tissue with large filtration area and cause lesion of immune complex disease? | experimental Arthus reaction, farmer’s lung disease |
