title: T and B lymphocytes in the cerebrospinal fluid of various neurological diseases.
abstract: Cerebrospinal fluids (CSF) from 66 patients with a variety of neurological disorders were studied for total protein content, absolute amount of albumin, IgA, IgG and IgM, as well as their quotients (fraction to total protein ratio), cell numbers and B cell and T cell levels. In addition, the percentage of B cells and T cells in the blood was determined in 34 patients and serum immunoglobulin levels were estimated in 51 patients. In noninflammatory diseases of the CNS, the percentage of B cells was slightly higher and T cell levels were lower in the CSF in comparison to corresponding blood values. The B cell to T cell ratio in viral meningitis was altered in the CSF. An apparent increase in the T cell level led to a decrease of B cell values. Similar changes were also found in optic neuritis. The percentage of T cells was higher in relapsing multiple sclerosis than in the chronic progressive form. There were less striking changes in the B cell to T cell ratios in the CSF of other inflammatory diseases of the CNS.
