Following infection with Leishmania major, the chemokines XCL1, CXCL10, and CCL2 were preferentially expressed in draining lymph nodes of resistant mice. Neutralization of interleukin 12 (IL-12) or gamma interferon in resistant mice resulted in decreased chemokine expression, while administration of IL-12 to susceptible mice resulted in an increase in the level of chemokine gene expression.
