New Therapeutic Target For Treatment Of Multiple Sclerosis Jan 25, 2008
However, they also impede the immune system's ability to provide protection against chronic viral infections of the central nervous system, such as progressive multifocal leukoencephalopathy, a demyelinating disease of the central nervous system caused by the JC virus. Since ALCAM/CD166 blockade does not affect CD8+ T cell migration, whose main function is to destroy cells infected by viruses and neoplastic cells, the study results suggest that CNS immune protection against viruses would not be...
