|
|
Term
|
Definition
| proteins (cytokines) that stimulate growth of B or T lymphocytes & activate specific components of the immune response |
|

|
|
Term
|
Definition
| lymphocyte that inhibits the activity of B and T lymphocytes |
|
|
Term
|
Definition
| lymphocyte that originates in the bone marrow but matures in thymus gland; acts directly on antigens to destroy them or produce chemicals (cytokines) such as interferons & interleukins that are toxic to antigens |
|
|
Term
|
Definition
