Proteins that attack microbes or stall reproduction of microbes.

Antimocrobial protein

1

Example of antimicrobial protein

Lysozyme

2

Secreted by virus-infected cells; prevent cell to cell spread.

Interferons

3

Not virus specific

Interferons

4

Neighboring cells are stimulated to produce chemicals that can inhibit viral infection

Interferons

5

A specific type that activated phagocytes; activate macrophage

Interferons

6

Secreted by macrophages

Defensins

7

Third line of defense. There is lag time between exposure and maximal response. Not genetically determined. Affords protection against re-exposure to the same pathogen.

Adaptive/Acquired immunity/Specific defense mechanism

8

Responsible in the defense mechanism. Found in the blood and lymph.

Lymphocytes

9

Activated by cytokines from phagocytes.
Display specificity to epitopes on antigens. Have specific membrane-bound antigen-receptors.

Lymphocytes

10

Two types of lymphocytes.

B- cells
T-cells

11

Mature in marrow

B-cells

12

Mature in thymus.
A.k.a helper/cytotoxic/killer/suppressor/memmory

T-cells

13

Requires some time to react to an invading organism

Adaptive

14

Present and ready to mobilized upon infection

Innate

15

Antigen specific and reacts only with the org that induced the response.

Adaptive

16

Not antigen specific and reacts equally to a variety of organism

Innate

17

Does not demonstrate immunological memoryo

Innate

18

Demonstrates immunological memory

Adaptive

19

Develops upon the exposure to antigen
Through antigen
Obtained in the course of daily life

Naturally Acquired Active Immunity

20

Occurs through vaccination

Artificially Acquired Active Immunity

21

Type of Acquired/Adaptive Immunity that has natural antibodies. No immune response to antigen.

Naturally Acquired Passive Immunity

22

Type of Acquired/Adaptive immunity: injection of antibodies

Artificially Acquired Passive Immunity

23

Adaptive Immunity can be?

Cellular (cell-mediated) and Humoral (antibody-mediated)?

24

Involves B cell activation; production of antibodies in blood plasma and lymph.

Humoral immunity

25

Involves immunoglobulin production by B lymphocytes; complement can be considered

Humoral Immunity

26

Humoral immunity:
Antibodies are produced by?

Lymphocytes; specifically B cells

27

Humoral immunity:
Antibodies are found where?

ECF and surface of B cells

28

Programmed cell death (Falling away)

Apoptosis

29

Many virus infected cell will undergo this to help prevent spread of the infection

Apoptosis
