Increased constitutive activation of NF-κB p65 (RelA) in peripheral blood cells of patients with progressive multiple sclerosis.

Abstract:

:The NF-κB signalling pathway plays an important role in controlling cellular immune responses, inflammation and apoptosis. In multiple sclerosis (MS), there is evidence of dysregulation of NF-κB signalling in patients with a relapsing-remitting disease course, but thus far there is little information on whether it is also dysregulated in patients with progressive disease. We hypothesised that patients with progressive MS would have more activation of NF-κB than relapsing-remitting MS patients. Using several different methods, we showed that there was more nuclear translocation of p65 in cells from progressive MS patients, particularly in T cells and monocytes. In addition, the amount of p65 translocated to the nucleus in cells of patients with progressive MS was not increased upon non-specific activation of the cells with the mitogen Con A. These results suggest that NF-κB dysregulation occurs in patients with progressive MS patients, as well as those with relapsing-remitting MS.
