Protein Substances; Innate Immunity - Second Line Defenses Flashcards
Describe antimicrobial peptides
Proteins made by the skin, mucous membranes and blood cells. They kill anything that shouldn’t be there.
What kind of spectrum of activity is antimicrobial peptides
Broad-spectrum Of activity
Do you antimicrobial peptides have resistance
Only when you take them out of the body
What are the outcomes of antimicrobial peptides
They kill foreign invaders and stimulate immune responses
Describe interferons
Cytokines made by virus-infected cells
What is the outcome of interferons
To prevent viral replication mean infected neighbor cells so their outcome is to stop the spread of the virus
Describe the complement system
It’s a series of C proteins in blood and tissue fluids and has various triggers and pathways for complement cascade(starts to organize itself)
What is the outcome of the complement system
Lysis of foreign cells the membrane attack complexes (MAC), Opsonization, inflammation
What are the protein substances of the second line defense
Antimicrobial peptides(AMP’s), Interferons (IFNs), complement system
