Rantes isachemotacticproteinforTcells,eosinophils,andbasophils. RANTESisproducedbycirculatingT-cells. ThesynthesisofRANTESisinducedbyTNF-alphaandIL1-alpha. Itplaysanactiveroleinrecruitingleukocytesintoinflammatorysites.WiththehelpofparticularcytokinesthatarereleasedbyTcells,Rantesalsoinducestheproliferationandactivationofcertainnatural-killer(NK)cellstoformCC-Chemokine-activatedkillercells. ItisalsoanHIV-suppressivefactorreleasedfromCD8+Tcells. RANTESincreasestheadherenceofmonocytestoendothelialcells.Principle:
