A

Thymus

18
Q

B cells and NK cells mature in the…?

A

Bone marrow

19
Q

What do T and B cells possess that NK cells do not?

A

An antigen specific receptor

20
Q

What is the difference in antigen specific receptors between B and T cells?

A

B cells = modified antibody molecule

T cells = T Cell Receptor (TCR)

21
Q

How is different cell types distinguished?

A

Cell surface proteins known as Cluster of Differentiation (CD)

22
Q

What are the two major groups of T cells?

A

CD4+ and CD8+

23
Q

What is the role of CD4+ T cells?

A

Helper cells –> They activate B cells or macrophages

24
Q

What is the role of CD8+ T cells?

A

Cytotoxic cells and kill virally infected cells.

25
Q

What is the Major Histocompatibility Complex (MHC)?

A

Contain and secrete mediators which play a role in immunity

26
Q

What machine can separate cells based on surface markers?

A

Flow cytometer / Fluorescent Activated Cell Sorting (FACS)
