Pathogenesis of central nervous system lesions in visna cell-mediated immunity and lymphocyte subsets in blood, brain, and cerebrospinal fluid.
The time course and titers of antibodies did not correlate with the severity of CNS lesions whereas the CMI did, indicating that CMI may play an important role in lesion development. The correlation of the number of CD8 positive cells in the CSF with the severity of lesions and the reversed ratio of CD4/CD8 positive cells in the diffusely infiltrated neuroparenchyma indicates that the CD8 positive T cells may be an important effector cell in the induction of CNS lesions.
