purpose

differentiate self from nonself, destroy harmful pathogens

2

two types

innate, acquired immunity

3

interferon

proteins made by infected cells alerting presence of virus

4

what is special about nk cells

only phagocyte in innate system to kill other human cells that dont produce MHC 1 protein

5

best phagocyte to activate acquired immunity

dendritic cells

6

complementc

cascade of bio rxn that lyses bad cells

7

what needs for inflammatory response

histamines by mast cells (basophils)

8

antigen def

(antibody generator) sth that causes immune system to ID a pathogen and create antibody (protein) against it. producex by B cells.

9

T and B cells both

grow in the bone marrow but T matures in the thymus gland, B, the same bone marrow.

10

antigen presentation

when phagocytes eat and shred up and present parts of foregin protein for Helper T cell to recognize

11

3 antigen presenting cells

dendriti, macrophage, b cell

12

plasma cells T and B cells

plasma T cells just go around signaling other lymphocytes to take action.
Plasma B cells actually pump out tons of antibody

13

how does helper T cell notify other lymphocytes?

secrete cytokines that activate B cells and cytotoxic t cells

14

When an antigen is bound to a Class I MHC molecule, it can stimulate a

cytotoxic T

15

When an antigen is bound to a Class II MHC protein, it can activate a

helper T cell

16

MHC (major histocompatibility complex) Class II molecules are a family of molecules normally found only on

antigen-presenting cells and lymphocytes.
