Effects of Alemtuzumab on (Auto)antigen-Specific Immune Responses.

ABSTRACT: Alemtuzumab (anti-CD52 mAb) leads to a long-lasting disease activity suppression in patients with relapsing forms of multiple sclerosis (MS). In this study, we examined the change of the immune cell repertoire and the cellular reactivity after treatment with alemtuzumab. We analyzed the number of IFN-γ-secreting cells in presence of several peptides which had been eluted from the central nervous system (CNS) of MS patients and are possible targets of autoreactive T cells in MS. The patients showed a stabilized disease activity measured in clinical parameters and lesion formation after the treatment. We detected a reduction of the number of IFN-γ-secreting cells in the presence of every tested self-antigen. The number of IFN-γ-secreting cells was also reduced in the presence of non-self-ant
