ABSTRACT
Alemtuzumab, a monoclonal antibody directed against human CD52, is used in the treatment of MS. To characterize the impact of anti-CD52 administration, a monoclonal antibody to mouse CD52 (anti-muCD52) was generated and evaluated in EAE mouse models of MS. A single course of anti-muCD52 provided a therapeutic benefit accompanied by a reduction in the frequency of autoreactive T lymphocytes and production of pro-inflammatory cytokines. Examination of the CNS revealed a decrease in infiltrating lymphocytes, demyelination and axonal loss. Electrophysiological assessment showed preservation of axonal conductance in the spinal cord. These findings suggest that anti-CD52 therapy may help preserve CNS integrity.
