Study Notes
Introduction to Autoimmunity
- Autoimmune conditions occur when the immune system mistakenly attacks the body's own cells.
- This breakdown in recognizing "self" versus "non-self" leads to immune dysfunction.
- Learning module focuses on disease processes, diagnosis, and treatment associated with autoimmunity.
- Course outcomes include analyzing pathophysiological mechanisms, examining homeostatic mechanisms, distinguishing risk factors and integrating advanced pathophysiological concepts across the lifespan.
B Cells
- Produce autoantibodies when activated by T cells that don't recognize "self" cells and activate an immune response.
T Cells
- Modulate immune activity and are involved in the breakdown of self-tolerance, potentially causing autoimmune reactions.
- T cells modulate the immune response by recognizing "self" versus "non-self", producing cytokines, and activating B cells.
Autoantibodies
- Bind to self-antigens, forming complexes that precipitate in tissues, causing inflammation.
Immune Complexes
- Precipitate in tissues, leading to inflammation and tissue damage.
- Formed from autoantibodies binding to self-antigens.
Complement System
- A group of proteins that, when activated, can cause cell lysis and inflammation.
Pathophysiological Events
- Genetic predisposition plays a role in susceptibility to autoimmune disorders.
- Environmental triggers (infectious or environmental) cause cell damage, initiating an immune response in genetically predisposed individuals.
- Autoantibodies are produced when immune cells engulf damaged cells and T cells respond to self-antigens, activating B-cells.
- Immune complexes form and deposit in tissues.
- Tissue damage results, including inflammation (vasculitis, rash).
Types of Autoimmune Diseases
- Systemic autoimmune diseases (e.g., SLE, rheumatoid arthritis, scleroderma, Sjögren syndrome, MCTD)
- Tissue-specific autoimmune diseases (e.g., endocrine disorders like type 1 diabetes, Hashimoto's Thyroiditis, Graves' Disease; GI autoimmune diseases, celiac disease, Crohn's Disease)
- Neurological autoimmune diseases (e.g., Multiple Sclerosis, Myasthenia Gravis)
- Dermatological autoimmune diseases (e.g., Psoriasis)
- Hematological autoimmune diseases (e.g., Immune Thrombocytopenic Purpura)
- Musculoskeletal autoimmune diseases (e.g., Ankylosing Spondylitis)
Systemic Lupus Erythematosus (SLE)
- A complex autoimmune condition impacting various organ systems.
- Genetic predisposition, environmental triggers (infection, UV exposure), cause cell damage leading to an immune response.
- Autoantibodies produce immune complexes deposit in tissues.
- Tissues damage inflammation (vasculitis, rashes).
- Common clinical manifestation include malaise, fatigue, rash, muscle and joint pain and difficulty breathing.
- Diagnoses often involve testing for antinuclear antibodies (ANA).
