Adaptive Cells

Question 1

small lymphocyte

Answer 1

• specific antigen receptors
• communicates with other cells by cytokines and receptors
• clonal proliferation

Question 2

What two major subgroups do small lymphocytes differentiate to?

Answer 2

1. b-cells-plasma cells that produce antibodies

2. t-cells-helper and killer and control cytokine production

Question 3

B-cells

Answer 3

• activated b-cells make antibody-antigen antibodies on their cell surface
• plasma cells-make antibody

Question 4

T-cells

Answer 4

• commanders in chief of the immune system
• Two major T-cell types
  1. cytotoxic tcells- similar to NK cells
  2. Helper Tcells- produce molecules and cytokines that direct the immune response by macrophages and b-cells as well as augment the recruitment of immune cells to the site of infection
