摘要
We studied how interferon-beta (IFN-beta) treatment of relapsing-remitting multiple sclerosis (MS) affects subgroups of natural killer cells (NK cells). Following IFN-beta treatment, there was an expansion of CD56(Bright) NK-cells in the peripheral blood of MS patients, while at the same time the proportion of CD56(Dim) cells was diminished. In a control group, the proportion of CD56(Bright) NK-cells was significantly higher in secondary lymphoid tissues compared to the peripheral blood of the same individual. Our findings confirm that CD56(Bright) NK-cells preferably locate within the secondary lymphoid tismes, where they may interact with T cells and thereby contribute to the control of the disease activity in MS.
