Ch 8 Adaptive Immunity Flashcards
Plasma cell
Antibody producing cell.
T-regulatory cell
Cell that suppresses activation of the immune sysytem’s response to self-antigens.
Hapten
Small antigen that binds to large molecules and induces an immune response.
Epitope
Portion of an antigen that is recognized and bound by an antibody or specific lymphocyte receptor.
Superantigen
Molecule that activates many Th2 cell receptors regardless of their antigen specificity by binding in an unusual location.
Pick the correct word: Human MCH (Major Histocompatibility Complex) molecules are known as (APC, HLA) antigens.
HLA (human leukocyte antigen)
Pick the correct word: MCH class I molecules present (exogenous, endogenous) antigens, whereas MCH class II molecules present (exogenous, endogenous) antigens.
endogenous
exogenous
Pick the correct word: (Dendrite cells, Macrophages) are the most effective in presenting antigen to naive immunocompetent Th cells.
Dendritic cells
Pick the correct word:
Physical interactions between B lymphocytes and (Th1, Th2) cells are necessary for B lymphocytes to become activated.
Th2
Pick the correct word:
Tissue typing to identify differences in (HLA antigens, dendritic cells) is performed before organ transplant to prevent transplant (mutations, rejection).
HLA antigens
rejection
Pick the correct word: Active or Passive
Neonate does not develop an infxn because she has maternal antibodies that she received in breast milk.
Passive
Pick the correct word: Active or Passive
Child does not develop an infxn because she has been immunized against it.
Active
Pick the correct word: Active or Passive
Man does not develop an infxn because he was infected with that same microorganism previously and recovered.
Active
Pick the correct word: Active or Passive
Woman does not develop and infxn because she was given gamma globulin after being exposed to an infected person.
Passive
Name the Ig
Most abundant class of Igs; are transported across the placenta.
IgG
Remember “G” for greatest number and goo goo gaga for babies. 4Gs for IgG1, IgG2, IgG3 and IgG4
