recruitment to the central nervous system in multiple sclerosis (MS). CCR5 Δ32, a truncated
allele of the CC chemokine receptor CCR5 gene encoding a non-functional receptor, did not
confer protection from MS. CCR5 Δ32 was, however, associated with a lower risk of
recurrent clinical disease activity. High CSF levels of MMP-9 activity were also associated
with recurrent disease activity. These results directly link intrathecal inflammation to disease …
