0

On mast cells/basophils
Allergic reaction
Lysis of parasitic worms

IgE

1

Monomer

Blood, lymph on B cells

B cell antigen receptor

Initiate immune response

IgD

2

Two types: Dimer, monomer

Present in mothers milk

Secretions/ mucosal protection

IgA

3

Pentameter

Activate complement system

Agglutinates microbs

First antibody produced in response to infection

IgM

4

Monomer

Only cross placenta

Enhance phagocytosis

Activate complement system

IgG

5

Process of destroying B and T cells that react to self antigens

Clonal deletion

6

Enhances phagocytosis and reduces number of infections units to be dealt with

Agglutination

7

Coating antigen with enhances phagocytosis

Opsonization

8

Blocks active site of toxin

Blocks adhesion of bacteria and viruses to mucous

Neutralization

9

Response of the body to the first contact with an antigen

Characterized by appearance of IgM followed by IgG

Primary response

10

Subsequent contact with the same antigen results in a very high antibody titer

Secondary response

11

Humoral antibody immunity

Antibody binds to bacteria, toxins and extra cellular viruses

B cells responsible for production

Specific immunity

12

Cellular immunity

Based on T cell attacks infected cells from viruses, transplanted cells, parasites, cancer cell

Specific immunity

13

Substance that is foreign to the body to trigger an immune response

Antigen
Ag

14

Proteins made in response to an antigen

Antibody
Ab

15

Study of reactions between antibodies and antigens

Serology

16

Serum proteins

Globulins

17

Cytokines that secs as communicators between lueukocytes

Interleukins
