Selective infiltration of eosinophils suggests the presence of the factors that attract eosinophils preferentially. Selective chemotactic polypeptides for human eosinophils were purified from thrombin-stimulated platelet supernatants and this chemotaxin was identified as the chemokine RANTES. The isolation of natural RANTES and its activity for eosinophil migration is summarized here. RANTES induced eosinophil migration at nanomolar range, in both chemotactic and chemokinetic manners. Specific desensitization experiments indicated that RANTES binds to receptors different from those for C5a and PAF, well-known potent eosinophil chemotaxins.

D018946 Chemokine CCL5 A CC-type chemokine that is a chemoattractant for EOSINOPHILS; MONOCYTES; and LYMPHOCYTES. It is a potent and selective eosinophil chemotaxin that is stored in and released from PLATELETS and activated T-LYMPHOCYTES. Chemokine CCL5 is specific for CCR1 RECEPTORS; CCR3 RECEPTORS; and CCR5 RECEPTORS. The acronym RANTES refers to Regulated on Activation, Normal T Expressed and Secreted.
