Week 2 Flash cards
Type I Atopic, Anaphylactic is mediated by
IgE (the immunoglobin)
Ag (antigen) –> releases histamines
Type I Atopic, Anaphylactic is CAUSED (2) by
Environmental factors
T-Cell deficiency
Type I Atopic, Anaphylactic EXAMPLES
Drug reactions –> know for test
Asthma, bee sting reactions
Type II: Cytotoxic, Cytolytic (cells breaking/dying) MEDIATED by
IgM or IgG
Type II: Cytotoxic, Cytolytic caused by
Exposure to Ag or foreign cells, tissues, or graft
Type II: Cytotoxic, Cytolytic examples
Wrong blood transfusions
Hemolytic disease of newborn
Type III: Immune Complex (arthus reaction) mediated by
IgG –> cause tissue damage or inflammation
Type III: Immune Complex CAUSED by
Autoimmunity
Persistent infection
Type III: Immune Complex EXAMPLES (4)
Autoimmune diseases
Systemic lupus (SLE)
Glomerulonephritis
Farmer’s lung arthritis
Type IV Delayed Hypersensitivity MEDIATED by
T-lymphocytes (no immunoglobins)
(remember this, it stands out from rest)
-Attracts macrophages
Type IV Delayed Hypersensitivity EXAMPLES
Tuberculin test
Multiple sclerosis
- Bence Jones protein
- Kidney damage
- Attacks bones (skulls, ribs, spine, pelvis)
- Hypercalcemia
- Honeycomb appearance
Multiple Myeloma
Hairy Cell Leukemia hallmarks
- Leukemia of mature B-cells
- Splenomegaly
- All blood cells decreased
Aplastic anemia (bone marrow destruction anemia) leads to?
Pancytopenia (decrease in all blood cells)
Pernicious Anemia is caused by?
Lack of intrinsic factor (can’t absorb B12)
