17
Q

Functions as suppressor cell.

A

18
Q

Phagocytize and processes antigen in the immune response.

A

ANS: macrophage

19
Q

Targets B cells and cause growth and differentiation.

A

ANS: TNF-α

20
Q

Targets B cells to cause class switching to IgA.

A

ANS: IL-5

Q

Anti-tumor factor that depresses protein synthesis in the target cell and causes the production of toxic free radicals.

A
