amplification system

Physiology A generic term for any group of proteins that function in coordinated sequences, forming positive feedback loops for expanding the response to a low intensity signal
Amplification systems
Coagulation,
eg factor Xa activating factor 'X' in the presence of factor VIII, Ca2+, and phospholipid
Complement
Augments B-cell response. See Alternative and Classic pathways

Cytokines
Amplifies T-cell response, ILs, kinins, lipid mediators and mast cell products

cytokines

A general term for a range of proteins of low molecular weight that exert a stimulating or inhibiting influence on the proliferation, differentiation and function of cells of the immune system. Cytokines include INTERLEUKINS and INTERFERONS.

Cytokines

Chemicals made by the cells that act on other cells to stimulate or inhibit their function. Cytokines that stimulate growth are called "growth factors."

cytokines (sīˑ·tō·kīnz),

n.pl regulatory proteins, such as lymphokines and interleukins that are produced by immune system cells and act as intercellular mediators in the modulation of immune response. Cytokines produced by recombinant DNA technology are administered to people to affect immune status.
