title: Costimulatory CD80 (B7-1) and CD86 (B7-2) on cerebrospinal fluid cells in multiple sclerosis.
abstract: The costimulatory CD80 and CD86 molecules were measured by flow cytometry on cerebrospinal fluid (CSF) and blood lymphocytes from patients with possible first attacks of multiple sclerosis (MS, n = 25), clinically definite MS (n = 16), and noninflammatory neurological disease control subjects (n = 30). In patients with demyelinating diseases more CSF B cells expressed CD80 than in control subjects whereas the expression of CD86 by T cells in CSF was low in patients with demyelinating disease and highly variable in the control subjects. In patients with possible first attacks of MS the expression pattern of CD80 and CD86 differed significantly between patients with or without intrathecal synthesis of IgG. Increased expression of the CD80 molecule on CSF B cells may be of importance in the pathogenesis of MS. In contrast, CSF T cell expression of CD86 may be associated with protection from MS.
