The flashcards below were created by user Neda317 on FreezingBlue Flashcards. What would you like to do?


  1. IL-1 func:
    An endogenous pyrogen, also called osteoclast-activating factor. Causes fever,acute inflammation. Activates endotheliumto express adhesion molecules; induces chemokine secretion to recruit leukocytes.
  2. IL-6 func
    An endogenous pyrogen. Also secreted by Th2 cells. Causes fever and stimulates production of acute-phase proteins. pro-inflammatory. 
  3. IL-8 func:
    Major chemotactic factor for neutrophils.
  4. IL-12 func:
    Induces differentiation of T cells into Th1 cells.Activates NK cells. Also secreted by B cells.
  5. TNF-a func:
    Mediates septic shock. Activates endothelium.Causes leukocyte recruitment, vascular leak.
  6. IL-2 func:
    Stimulates growth of helper, cytotoxic, and regulatory T cells.
  7. IL-3 func:
    Supports the growth and differentiation of bone marrow stem cells. Functions like GM-CSF.
  8. Interferon-γ func:
    • Has antiviral and antitumor properties.Activates NK cells to kill virus-infected cells,Increases MHC expression and antigen
    • presentation in all cells.
  9. IL-4 func:
    Induces differentiation into Th2 cells. Promotes growth of B cells. Enhances class switching to IgE and IgG.
  10. IL-5 func:
    Promotes differentiation of B cells. Enhances class switching to IgA. Stimulates the growth and differentiation of eosinophils.
  11. IL-10 func:
    Modulates inflammatory response. Inhibits actions of activated T cells and Th1. Also secreted by regulatory T cells.
  12. Interferon alpha and beta func:
    • A part of innate host defense against both RNA and DNA viruses. Interferons are glycoproteins synthesized by viral-infected cells that act locally on uninfected cells,“priming them” for viral defense. When avirus infects “primed” cells, viral dsRNA activates:ƒƒ
    • -RNAase L Ž--> degradation of viral/hostmRNA.ƒƒ
    • -Protein kinase -->Ž inhibition of viral/hostprotein synthesis.
    • Essentially results in apoptosis, therebyinterrupting viral amplification.
  13. T cell Cell surface proteins
    • TCR (binds antigen-MHC complex)
    • CD3 (associated with TCR for signaltransduction)
    • CD28 (binds B7 on APC)
  14. helper T cell Cell surface proteins
    CD4, CD40 ligand
  15. cytotoxic T cell Cell surface proteins
    CD8
  16. B cell Cell surface proteins
    Ig (binds antigen)CD19, CD20, CD21 (receptor for EBV), CD40MHC II, B7
  17. macrophages Cell surface proteins
    CD14, CD40MHC II, B7Fc and C3b receptors (enhanced phagocytosis)
  18. NK cells Cell surface proteins
    CD16 (binds Fc of IgG), CD56 (unique markerfor NK)
  19. Anergy
    Self-reactive T cells become nonreactive without costimulatory molecule. B cells also become anergic, but tolerance is less complete than in T cells.
  20. After exposure to _____ patients are given preformed antibodies (passive)
    • "To Be Healed Rapidly”
    • After exposure to Tetanus toxin, Botulinum toxin, HBV, or Rabies virus, patients are given preformed antibodies (passive)

    induces a cellular response.
  24. Inactivated or killed vaccine induce
    Humoral immunity induced
  25. Arthus reaction
    reaction—a local subacute antibodymediated hypersensitivity (type III) reaction. Intradermal injection of antigen induces antibodies, which form antigen-antibody complexes in the skin. Characterized by edema, necrosis, and activation of complement.
  26. Serum sickness
    an immune complex disease (type III) in which antibodies to the foreign proteins are produced (takes 5 days).Immune complexes form and are deposited in membranes, where they fix complement (leads to tissue damage). More common than Arthus reaction.
