|
Apoptosis |
Programmed death of "self" cells that does not cause inflammation |
|
|
Complement system |
Series of proteins in blood and tissue fluids that can be activated to help destroy and remove invading microbes |
|
|
Cytokines |
Proteins that function as chemical messengers, allowing cells to communicate |
|
|
Inflammatory response |
Coordinated innate response with the purpose of containing a site of damage, localizing the response, eliminating the invader and restoring tissue function. The signs of inflammation are swelling, heat, redness and pain in the infected area |
|
|
Innate immunity |
Host defenses involving anatomical barriers, sensor systems that recognize patterns associated with microbes or tissue damage, phagocytic cells, and the inflammatory |
|
|
Macrophage |
Type of phagocytic cell that resides in tissues and has multiple roles, including scavenging debris and producing pro-inflammatory cytokines |
|
|
Membrane attack complex (MAC) |
Complement system components that assemble to form pores in the membranes of invading cells |
|
|
Neutrophil |
Major type of phagocytic cell in blood; neutrophils quickly move to infected tissues to destroy invading microbes |
|
|
Opsonization |
Coating of an object with molecules for which phagocytes have receptors, making it easier for phagocytosis to occur |
|
|
Pattern recognizing receptors (PRRs) |
Proteins on or in cells that recognize specific compounds unique to microbes or tissue damage, allowing the cells to sense the presence of invading microbes or damage |
|
|
Phagocyte |
Cell type that specializes in engulfing and digesting microbes and cell debris |
|
|
Phagocytosis |
The process by which a phagocyte engulfs an invader |
