Adaptive immunity Flashcards
What are the 2 classes of lymphocytes in adaptive immunity?
B cells.
T cells.
What am I?
Produce antibodies that attack pathogens
B cells.
What am I?
Attack pathogens more directly.
T cells.
What are the 5 stages of adaptive immunity?
- Recognition of antigen
- Activation of lymphocytes
- Effector phase (immune attack)
- Decline of antigen causes lymphocyte death
(homeostatic balance) - Memory cells remain for later response if needed
Where are T cells created?
In the thymus.
Where are B cells created?
Red bone marrow.
What does NK cells release to kill abnormal cells?
Perforins.
Granzymes.
What must a normal cell possess for an NK cell to release killer-inhibiting receptor?
MHC class 1 module.
What are the three functions of T cells?
- Cytotoxic T cells
- Helper T cells
- Suppressor T cells
Which cell assist and regulate the function of B cells, T cells and leukocytes?
Helper cell
Which cell suppresses lymphocyte function, regulate immunity, and promotes self tolerance.
Suppressor cell
Which cell releases lymphotoxin to kill cells
Cytotoxic cell
What are the 5 types of antibodies?
IgA
IgD
IgE
IgG
IgM
Which antibody am I?
Can cross placenta to provide immunity to new-born/foetus and is most common?
IgG
