Research Abstract |
Using simultaneous staining of four chemokine receptors, we identified a unique T cell population increased in the cerebrospinal fluid of patients with relapsing multiple sclerosis. CCR2+CCR5+ T cells were selectively enriched in the cerebrospinal fluid of multiple sclerosis patients but not of patients with other inflammatory and non-inflammatory neurological diseases. We found that CCR2+CCR5+ T cells from peripheral blood of multiple sclerosis patients in relapse specifically responded to myelin basic protein and produced both interferon-γ and interleukin-17. Of note, we demonstrated that the CCR2+CCR5+ population possesses a distinct ability to produce matrix metalloproteinase-9 and osteopontin, both of which are thought to be crucial for the invasion into the parenchyma. We propose that the CCR2+CCR5+ T cells may play a role in triggering brain autoimmune inflammation.
