Type II Hypersensitivity Disorders - Cytotoxic:
Transfusion Reaction
- Antibody against _____
- IgM isohemagglutinins formed naturally in response to bacterial flora cause opsonization and complement activation
- Leads to hemolysis
**Hemolytic Disease of the Newborn (Erythroblastosis fetalis)
Antibody = _____
- Formed in _____ mother carrying _____ child
- First pregnancy _____ (doesn't have to be viable pregnancy)
- Antibody crosses placenta and injures subsequent fetuses
- Prevent with _____ (anti-Rh, binds fetal red cells and prevents mothers immune system from reacting)
ABO blood typing and screening for other preformed Abs; always done in case of transplants.
Universal donor: type _____
Universal recipient: type _____
(Ex) Type A can donate to _____ and _____. Type A can receive donations from _____ and _____.
- Anti-B antibodies prevent donation from type B and type AB.
HLA Typing - Microcytotoxicity test
Tests for MHC _____
Test hundreds of different haplotypes to find a potential match.
Cells recognized by antibody will be attacked by complement and thus become leaky and take up dye.
HLA Typing - Mixed lymphocyte reaction
Tests for MHC class _____
Take donor cells and irradiate them (prevent proliferation). Irradiated cells are mixed with donor cells to see if proliferation occurs.
Higher radioactivity (thymidine) signifies _____ compatibility.
#10
_____ cells are plasma cells characterized by the accumulation of multiple Russell bodies
