MCP-1 in the cerebrospinal fluid of children with acute lymphoblastic leukemia.

CNS involvement in ALL is associated with significantly higher levels of MCP1 during therapy. This significant rise in MCP-1 levels might be one of the mechanisms involved in the regulation of CNS leukemia. Since chemokines target specific leukocyte subsets, inhibition of a single Chemokine ligand or receptor may have a circumscribed effect, endowing the inhibitor with a limited side effect profile. Chemokines should be considered as possible targets for therapeutic intervention.
