Lesson 17 Part 2 Flashcards
Small, anti-viral proteins produced by virus infected cells
Interferons
They “interfere” with viral replication
Interferons
Three known type of Interferons
Alpha (a)
Beta (b)
Gamma (y)
Produced by B lymphocytes (B cells), monocytes and macrophages
A-interferon
Produced by fibroblast and other virus-infected cells
B-interferom
Produced by T-lymphocytes and natural killer cells
Y-interferon
The compelment system is also known as
Complement cascade
A non-specific host defense mechanism that assists in the destruction of many different pathogens
Complement cascade
A process by which phagocytosis is facilitated by the deposition of opsonins
Opsonization
A process by which phagocytosis is facilitated by deposition of opsonin
Opsonizatiom
Plasma levels of molecules increase rapidly in response to infection, inflammation, and tissue injury
Acute-phase protein
Used as a laboratory marker for, or indication of, inflammation
C-reactive proteins
Chemical mediators that are release from many different types of cell in human body
Cytokines
The body normally responds to any local injury, irritation, microbial invasion, or bacterial toxin
Inflammation
The primary purpose of the inflammatory response are to:
- Localize an infection
- Prevent the spread of microbial invader
- Naturalize any toxin being produced at the site
- Aid in repair of the damage tissue
