Study Notes
Antibody-Mediated Cell Destruction
- Antibody-mediated destruction of cells involves phagocytosis and cell destruction.
- Transfusion Reactions: Mismatched blood transfusions lead to pre-formed antibodies reacting with donor cells, opsonizing them for destruction.
- Hemolytic Disease of the Fetus and Newborn (Erythroblastosis Fetalis): Maternal IgG anti-erythrocyte antibodies cross the placenta, attacking fetal red blood cells due to maternal-fetal blood group incompatibility.
- Autoimmune Hemolytic Anemia, Agranulocytosis, and Thrombocytopenia: An individual's immune system produces antibodies targeting their own blood cells, causing their destruction.
-
Drug Reactions: Certain drugs can trigger antibody-mediated destruction of blood cells in two main ways:
- Drug binding to host cell membrane proteins, creating antibody targets.
- Drug altering the shape of antigens, producing new antigenic surfaces attacked by the immune system.
