Antibodies 1 Flashcards
1
Q
function of immune system
A
protection against disease processes
2
Q
immune sytem divided into
A
innate + adaptive
3
Q
characteristics of adaptive system
A
- can specifically recognise foreign body
- ability to remember foreign body
- adapts its response to deal with new invaders
4
Q
sub-divisions of adaptive system
A
- cellular - T lymphocytes
- humoral - B lymphocytes
5
Q
T cells function + types
A
- mediate cellular immune response
- T helper
- T cytotoxic
- T regulatory
6
Q
B cells function
A
mediate humoral immune system by producing antibodies
7
Q
specificity of antigen recognition is achieved through…
A
antigen-binding receptors on surface of B & T cells
8
Q
antigen binding receptors of T cells
A
T cell receptor
9
Q
antigen binding receptors of B cells
A
immunoglobulin receptor cells
10
Q
functions of antigen binding receptors
A
- recognise all pathogenic antigens
- initiate production of specific responses
11
Q
where does antigen recognition occur?
A
secondary lymphoid organs
12
Q
1 lymphocyte =
A
1 specificity
13
Q
how does B lymphocytes produce antibody?
A
- binds to only 1 antigen + becomes activated
- activated B cell differentiates
- produces antibodies with same specificity
14
Q
antibodies are Igs…
A
- secreted into circulation by B cells which binds antigen
- soluble, secreted Igs which are free floating in plasma
15
Q
membrane-bound Igs
A
- antigen binding receptors on B cells surface
- not free floating in plasma
