Study Notes
Hypersensitivity Reactions
- Type III hypersensitivity reaction involves the formation of immune complexes that lead to chronic inflammation and tissue destruction.
Cytotoxic T Cells
- Cytotoxic T cells are typically involved in Type IV hypersensitivity reactions.
Arthus Reaction
- The Arthus reaction is a Type III hypersensitivity reaction.
Autoantibodies
- Autoantibodies against self-tissues or organs characterize Type II hypersensitivity reactions.
Allergic Contact Dermatitis
- Allergic contact dermatitis caused by poison ivy involves Type IV hypersensitivity reactions.
Cell Destruction
- Type II hypersensitivity reactions can destroy or alter cells by four mechanisms.
Type I Allergies
- Histamine is the main mediator responsible for the clinical manifestations of Type I allergies.
- Type I allergies are IgE-mediated and require sensitization by repeated exposure to allergens.
Type III Allergies
- Type III allergies are characterized by the presence of immune complexes leading to chronic inflammation and tissue destruction.
Type IV Allergies
- Type IV allergies are characterized by a delayed hypersensitivity reaction mediated by T cells.
Hyperthyroidism
- Hyperthyroidism is caused by Graves' disease, an autoimmune disease.
Autoimmune Disease
- Myasthenia gravis is an autoimmune disease involving the binding of autoantibodies to acetylcholine receptors.
Multiple Sclerosis
- Multiple Sclerosis is characterized by demyelination of the nervous system.
Diabetes
- Type I diabetes differs from Type II diabetes in that it involves the destruction of pancreatic beta cells, leading to an absolute insulin deficiency.
Neuromuscular Autoimmunities
- T cells play a role in neuromuscular autoimmunities by destroying or altering cells.
Allergic Reactions
- Anaphylaxis is a Type I allergic reaction characterized by local and systemic reactions such as urticaria and bronchospasm.
Mastocytosis
- Mastocytosis is a rare disorder characterized by mast cell proliferation leading to symptoms like flushing, abdominal pain, and hypotension.
Insulin Allergy
- Insulin allergy is a Type I allergic reaction usually involving local reactions that disappear after the first 4 weeks of therapy.
Latex Allergy
- Latex allergy is a Type IV allergic reaction often associated with anaphylaxis in certain individuals.
Contact Dermatitis
- Contact dermatitis caused by poison ivy and metals involves Type IV hypersensitivity reactions.
Mast Cell Degranulation
- During degranulation, mast cells release histamine, which contributes to the clinical manifestations of Type I allergies.
Transplant Rejection
- Transplant rejection involves a Type IV hypersensitivity reaction.
Tc Cell Destruction
- Tc cells are involved in the destruction of target cells in Type IV hypersensitivity reactions.
Autoantibodies
- Autoantibodies against self-tissues typically occur in Type III hypersensitivity reactions, leading to chronic inflammation and joint destruction.
Systemic Lupus Erythematosus (SLE)
