Cards

Term
Pluripotent stem cells
Definition
A cell type that is capable of becoming a variety of different cell types
Term
Colony forming unit
Definition
A committed stem cell that will produce a cell type
Term
Cytokines
Definition
Substances that regulate cellular activities by acting as chemical messengers among cells
Term
Colony-stimulating factors
Definition
A group of cytokines that stimulate pluriptent stem cells to produce a cell type
Term
Erythropoietin
Definition
A colony stimulating cytokine secreted by th kidney to stimulate red blood cell production
Term
Thrombopoietin
Definition
A colony stimulating cytokine secreted by the liver and kidneys to stimulate red blood cell production
Term
Interferon
Definition
Disrupts viral replication
Term
Interleukins
Definition
Multiple cytokines 1 - 18 that conduct immune system modulation in angiogenesis, inflammation, and creation of c-reactive protein
Term
Tumor necrosis factor
Definition
Cytokines produced by activate macrophages. TNF alpha associated with debilitation and with loss in clients with cancer. TNF beta is also called lymphotoxin
Term
Lymphocytes
Definition
Colorless weakly motile cells originating from stem cells and differentiating in lymphoid tissue
Term
Acquired immunity
Definition
Immunity that the organism developed buy the immune system in response to environmental antigen
Term
Active immunity
Definition
Process by which anibodies are formed
Term
Passive immunity
Definition
Process by which antibodies are formed by another person or animal and transferred to the host
Term
Antigen
Definition
Substances that initiate immune responses
Term
Hapten
Definition
Incomplete antigen
Term
Antibodies
Definition
Substances produced by immune system after exposure to antigen
Term
Immunoglobins
Definition
Proteins that interact with specific antigens that assists information of antigen-antibody complexes and opsonization
Term
Helper T Cells (CD4)
Definition
Produce cytokines
Term
Suppressor T Cells (CD8)
Definition
Stop the immune response when antigen is destroyed
Term
Cytotoxic T cells
Definition
Secrete interleukin 2 that assists the T-cell to bind to the antigen. Theses cells form holes in target cell membranes. Are especially lethal to viruses
Term
B-lymphocytes
Definition
Lymphocytes that secrete antibodies
Term
Mast cells
Definition
Granulocytes that occur especially in connective tissue and has basophilic granules containing substances (as histamine or heparin) which mediate allergic reactions
Term
Complement
Definition
Thermolabile group of proteins in a normal blood serum and plasma that work along side antibodies to destroy antigens
Term
Chemotaxis
Definition
Process by which lymphocytes leave the bloodstream and move into the injured or inflamed tissue
Term
Biological response modifiers
Definition
Medications that either enhance or restrict immune responses to various disease processes
Term
Vaccines
Definition
Suspensions of microorganisms or their antigenic products that have been killed or attenuated so that they can induce antibody formation
Term
Toxoids
Definition
Bacterial products that have been modified to destroy toxicity while retaining antigenic properties
