Lysozyme
|
|
|
To shed the cuticle in scales; to peel off the outer layer of a surface.
|
desquamated
|
|
|
A cytoplasmic organelle containing lysosome and other hydrolytic enzymes.
|
lysosyme
|
|
|
The study of the system of body defenses that protect against infection.
|
immunology
|
|
|
White blood cells. The primary infection-fighting blood cells.
|
leukocytes
|
|
|
Molecules recognized by the immune system as containing foreign markers, indicating a need for immune response.
|
non-self
|
|
|
Natural markers of the body that are recognized by the immune system.
|
self
|
|
|
Unique molecular structures on microbes that are recognized by the immune system.
|
Pathogen-associated molecular patterns (PAMPs)
|
|
|
Surface molecule on white blood cells that can detect and interact with surface molecules on bacteria and viruses. Toll-like receptors are one example of PRRs.
|
Pattern recognition receptors (PRRs)
|
|
|
An enzyme present naturally in cells that cleaves specific locations on DNA. It is an important means of inactivating viral genomes and it is also used to splice genes in genetic engineering.
|
Reticuloendothelial System (RES)
|
|
|
A collection of monocytes and macrophages scattered throughout the extracellular spaces that function to engulf and degrade foreign molecules.
|
Mononuclear Phagocyte System
|
|
|
A liquid connective tissue consisting of blood cells suspended in plasma.
|
Whole blood
|
|
|
Cellular components of the blood consisting of red blood cells, primarily responsible for the transport of oxygen and carbon dioxide, and white blood cells, primarily responsible for host defense and immune reaction.
|
Blood cells
|
|
|
The carrier fluid element of blood.
|
Plasma
|
|
|
The clear fluid expressed from clotted blood that contains dissolved nutrients, antibodies, and hormones but not cells or clotting factors.
|
Serum
|
|
|
The process by which the various types of blood cells are formed, such as in the bone marrow. Also called Hematopoesis.
|
Hemopoiesis or Hematopoesis
|
|
|
Pluripotent, undifferentiated cells.
