Autoimmunity Flashcards
Autoimmunity
Immune system mistakenly attacking self.
Breakdown in self tolerance
Autoimmunity: Pathophysiology
Tolerance: Untrained t-cells, too few t-reg cells
Balance: Th1: Th2 balance. Th1 and Th17 - > most autoimmune. Th2 -> SLE
Cross-reactivity: mimicry and tissue damage, micro-organisms, food (gluten, dairy)
Autoimmune: Major Histocompatibility Complex
MHC: encodes cell surface proteins (HLAs) and identifies self
Dysfunction -> autoimmune
Autoimmune and Micro-organisms
EBV: RA, MS, SLE
Strep: Psoriasis
E.Coli, Clostridium difficile: IBD
Klebsiella: Ankylosing spondylitis, RA
Yersinia: Graves and Hashimoto

Systemic Autoimmune Response Th2
Butterfly skin rash
Joint inflammation and fatigue
Pathophysiology: defective clearance of cell debris -> immune response
