Flashcards in Immunology Deck (11):
1

Cell-Mediated Immunity

Involves direct cellular response to invasion as opposed to antibodies
Cytotoxic T-cells wipe out cells that are infected by a virus

2

Humoral Immunity

Immunity involving antibodies

3

Plasma Cell

Cell that produces antibodies and functions in the elimination of any cell containing on its surface the antigen that it has been summoned to kill

4

Antigen

A molecule that is foreign to our bodies and causes our immune system to respond

5

Helper T cells

Assist in the activation of B Cells
Recognize foreign antigen on the surface of phagocytic cells and bind to these cells
They then multiply to produce a bunch of T cells that pump out chemical signals, which cause the B cells to respond

6

Cytotoxic T cells

The main cells involved in cell-mediated immunity
They recognize cells that productive viral antigens and wipe them out.

7

T cells

Mature in the thymus
Two main types: helper T cells and cytotoxic T cells

8

B cells

Mature in the bone marrow
Two main types" plasma cells and memory B cells

9

Phagocytes

Immune cells (macrophages and neutrophils) that use endocytosis to engulf and eliminate foreign invaders

10

Lysozyme

Enzyme that can kill germs before they have a chance to take hold
Present in saliva and tears

11

Nonspecific Immunity

Nonspecific prevention of the entrance of invaders into the body
