Definition of Chemokines

Chemokines Definition from Medicine Dictionaries & Glossaries
Aging Hearts and Arteries Glossary
A type of cytokine that carries messages between cells. In a sense, they tell cells where to go. If chemokines are increased in a particular tissue, such as an artery, the cell with the receptor, or partner, for that particular molecule is attracted to move into that tissue.

Glossary of HIV/AIDS-Related Terms
Also called beta chemokines. Studies of the relationship between HIV and these immune system chemicals have shown the complex exchanges that take place when HIV and white blood cells meet. Chemokines are intracellular messenger molecules secreted by CD8+ cells<!-- (see) --> whose major function is to attract immune cells to sites of infection. Recent research has shown that HIV-1 needs access to chemokine receptors on the cell surface to infect the cell. Several chemokines -- called RANTES, MIP-1A, and MIP-1B -- interfere with HIV replication by occupying these receptors. Findings suggest that one mechanism these molecules use to suppress HIV infectivity is to block the process of fusion<!-- (see) --> used by the virus to enter cells.

English Wikipedia - The Free Encyclopedia
Chemokines (Greek -kinos, movement) are a family of small cytokines, or signaling proteins secreted by cells. Their name is derived from their ability to induce directed chemotaxis in nearby responsive cells; they are chemotactic cytokines.
