|
Pluripotent stem cells
|
A cell type that is capable of becoming a variety of different cell types
|
|
|
Colony forming unit
|
A committed stem cell that will produce a cell type
|
|
|
Cytokines
|
Substances that regulate cellular activities by acting as chemical messengers among cells
|
|
|
Colony-Stimulating Factors
|
A group of cytokines that stimulate Pluripotent stem cells to produce a cell type.
|
|
|
Erythropoietin
|
A Colony stimulating cytokine secreted by the kidney to stimulate red blood cell production.
|
|
|
Thrombopoietin
|
A colony Stimulating cytokine secreted by the liver and kidneys to stimulate platelet blood cell production.
|
|
|
Interferon
|
Disrupts viral replication.
|
|
|
Interleukins
|
Multiple cytokines 1-18 that conduct immune system modulations in angiogenesis, inflammation, and creation of C-reactive protein.
|
|
|
Tumor Necrosis Factor
|
Cytokines produced by activated macrophages. TNF alpha is associated with debilitation and weight loss in clients with cancer.TNF beta is also called lymphotoxin. Page 629
|
|
|
Lymphocytes
|
Colorless weakly motile cells originating from stem cells and differentiating in lymphoid tissue.
|
|
|
Acquired immunity
|
Immunity that the organism developed by the immune system in response to environmental antigen.
|
|
|
Active immunity
|
Process by which antibodies are formed
|
|
|
Passive immunity
|
Process by which antibodies are formed by another person or animal and transferred to the host.
|
|
|
Antigen
|
Substances that initiate immune responses. Incomplete antigens are called haptens.
|
|
|
Antibodies
|
Substances produced by immune system after exposure to antigen.
|
|
|
Immunoglobins
|
Proteins that interact with specific antigens that assists in formation of antigen-antibody complexes and opsonization.
|
|
|
Helper T cells
|
Also called (CD4 cells) that produce cytokines. Suppressor T cells Also called (th1, Th2) thought to stop the immune response when antigen is destroyed. This process is impaired in autoimmune diseases.
|
|
|
Cytotoxic T cells
|
Secrete interleukin 2 that assists the T-cell to bind to an antigen. These cells form holes in target cell membranes. Cytotoxic T cells are especially lethal to viruses.
|
|
|
B lymphocytes
|
Lymphocytes that secrete antibodies.
|
|
|
Mast Cells
|
Granulocytes that occurs especially in connective tissue and has basophilic granules containing substances (as histamine and heparin) which mediate allergic reactions.
|
|
|
Complement
|
Thermolabile group of proteins in a normal blood serum and plasma that work along side antibodies to destroy antigens.
|
|
|
Chemotaxis
|
Process by which lymphocytes leave the blood stream and move into the injured ore inflamed tissue. (page 355)
|
|
|
Biological response modifiers
|
Medications that either enhance or restrict immune responses to various disease processes.
|
|
|
Vaccines
|
Suspensions of microorganisms or their antigenic products that have been killed or attenuated so that they can induce antibody formation.
|
|
|
Toxids
|
Bacterial products that have been modified to destroy toxicity while retaining antigenic properties.
|
