antibodies, interleukin I, etc.
Show Answers:

  1. IgD
    antibodies are used as B cell receptors
  2. IgM
    antibodies are the first to be produced but can't pass through the placenta
  3. IgG
    antibodies, appear later in primary immune response as a result of class switching, they are the most common antibodies and can pass through the placenta
  4. IgA
    antibodies are produced when plasma cells located in mucous membranes and mammary glands class switch. found in mother's milk
  5. IgE
    antibodies normally attack parasitic worms, but if they attach to mast cells and basophils they  mediate immediate hypersensitivity reactions (allergies)
  6. which antibody is associated with allergies
  7. which antibody is the first to appear but can't pass through placenta
  8. which antibody can pass through the placenta
  9. Ig
  10. B cell growth factor
    encourages activated B cells to grow and multiply (produced by helper II)
  11. B cell differentiation factor
    instructs B cells to stop multiplying, differentiate into plasma cells and start producing antibodies (produced by helper II)
  12. gamma interferon
    helps activate T cytotoxic cells, increases the ability of plasma cells to produce antibodies, keeps macrophages at the site of an infection and helps them digest the cells they have engulfed, stimulates suppressor cells. (produced by helper I and helper II)
  13. interleukin II
    • produced by both helper I and helper II
    • stimulates T helper cells and helps activate naive T cd8 cells
    • helps activates naive B lymphocytes by binding to cd24 receptors
  14. interleukin IV
    • increases the ability of plasma cells to produce antibodies
    • produced by T cells
  15. perforin
    form pores in the cell membrane of the infected cell
  16. antibody
    • a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances that the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.
    • third line of defense (humeral)
  17. interleukin I
    • produced by macrophages which bind to cd4 cells
    • is a lymphokine
    • helps activate naive Tcd4 cells
    • stimulates the brain ┬áto raise the body's temperature
    • makes the body more inhospitable to microbes
    • enhances activity of immune cells and interferon
    • increases microbial demand for iron
    • reduces the host's absorption of iron
  18. lymphokine
    chemicals produced by white blood cells that target other white blood cells and influence their behavior
