Presentation Transcript
humoral immunity key terms
HUMORAL IMMUNITY-KEY TERMS:
  • ANTIGEN:
    • a substance that can stimulate the body to produce antibodies
  • ANTIBODY:
    • a substance produced by the body to destroy or inactivate a foreign substance (antigen)
  • ANTIGEN-ANTIBODY complex has a lock and key fit.
agglutination
Agglutination:
  • The clumping of microbes/cells when held together by antibodies
b lymphocyte activation humoral response
B-lymphocyte activation (Humoral Response)
  • B-lymphocyte searches for antigen matching its receptor
  • If found, triggering signal is set off
  • Helper T cells release activating proteins (cytokines) B/cytotoxicT cells
  • B cells divide into plasma cells and B memory cells
    • Plasma cells release antibodies
    • B memory cells: prolonged life span, “remember” specific intruders

immune disorders
Immune Disorders
  • Allergy – Hypersensitivity to relatively harmless environmental antigen
  • Autoimmunity – Inappropriate/excessive response to self-antigens (molecules native to the person = self)
  • Lupus – Inflammatory disease that affects many tissues (joints, blood vessels, kidneys, nervous system, skin)
  • HIV/AIDS – Targets certain T-cells, destroying them (CD4-T cells most often targeted)
thrombocytes platelets
THROMBOCYTES:Platelets
  • No nucleus
  • Cell “fragments”
  • Irregular, disc shaped
  • Clot blood
  • Help maintain endothelial lining
clotting mechanism
CLOTTING MECHANISM
  • Injury to blood vessel; clotting factors are released into the plasma
    • Platelets form soft “platelet plug”
    • Prothrombin activator released
  • Prothrombin activator converts prothrombin into thrombin
  • Thrombin reacts with fibrinogen to form fibrin, a fibrous gel
  • Fibrin tangles RBC’s & platelets to form clot
clotting disorders
Clotting Disorders
  • Thrombosis
    • Clot forms in unbroken blood vessels = thrombus
  • Embolism
    • Clot dislodges (embolus)
  • Hemophilia
    • Inherited disorder
    • Lack of clotting factor, important plasma proteins for clotting
  • Thrombocytopenia
    • Decreased platelet count
    • Bleeding from small blood vessels throughout body
