Epstein-Barr–negative MS: a true phenomenon?
نویسندگان
چکیده
Epstein-Barr virus (EBV) infection is associated with MS; up to 3.3% people with MS are EBV nuclear antigen-1 (EBNA1)-seronegative compared with 6.0% controls. EBV serology is complex, and multiple antigens are required to assess seropositive status. We examined a cohort of seemingly EBV-negative patients with clinically isolated syndrome (CIS). The size of the population enrolled in the International CIS study allowed us to examine the largest population of seemingly EBV-negative patients with CIS gathered to date.

EBV-carrying human cell lines, depending on whether the cells are derived from Burkitt's lymphoma (BL) tumor biopsies or transformed by EBV in vitro, have different growth properties in vitro. In contrast, there are no clear differences between tamarin tumor lines and tamarin LCLs in vitro. Both types of tamarin cell lines could grow in agarose and formed colonies unlike human LCLs, althoug...
