Specific Immunity 3

Question 1

What is humoral response

Answer 1

Humoral response is response involving B cells

Question 2

What is cell mediated response

Answer 2

Cell mediated response is response involving T killer cells

Question 3

What is APC in humoral response

Answer 3

APC in humoral response is a B cell that has engulfed a pathogen

Question 4

What is APC in activation of T helper cells

Answer 4

APC in activation of T helper ell is a macrophage that has engulfed a pathogen

Question 5

What is APC in cell mediated response

Answer 5

APC in cell mediated response is a host cell that has engulfed a pathogen.

Question 6

How are cytokines involved in humoral response

Answer 6

Cytokines are involved in humoral response because cytokines from activated Thelper cell with complementary receptors to same antigen. T helper cell binds to APC via CD4 receptors

Question 7

Are cytokines involved in activation of T helper and T killer cells

Answer 7

Cytokines aren’t involved in activation of T helper cells but are involved in activation if T killer cells.

Question 8

What is function of cytokines

Answer 8

Function of cytokines is help stimulate division and differentiation of active cell

Question 9

How do activated B cells contribute to attacking pathogen

Answer 9

Activated B cells contribute to attacking pathogen by differentiating into B effector cell which differentiates into plasma cell. Plasma cell produces antibodies

Question 10

How do activated H helper cells contribute to attacking pathogen

Answer 10

Activated T helper cell contribute to attacking pathogen by producing cytokines which promote division and differentiation of B cells and T killer cells.

Question 11

How do T killer cells contribute to attacking pathogen

Answer 11

T killer cells contribute to attacking pathogen by destroying infected host cells and their contents.
