Regakine-1 enhances the lymphocyte chemotactic response toward MCP-3.

Different concentrations of MCP-3 (0-30 ng/mL) and pure natural Regakine-1 (0-300 ng/mL) were combined in the lower compartment of the microchamber to induce lymphocyte chemotaxis. The mean CIs are derived from 4 to 9 independent experiments. Statistically significant increases above the additive effect of the individual chemokines, determined by the Mann-Whitney test, are indicated by asterisks (*P < .1).
