- Abstract
- The serum and CSF of two women with a severe subacute pancerebellar syndrome contained high titers of antibodies directed against antigens present in the perikaryon of Purkinje cells. In Western blots performed on human Purkinje cells extracts these antibodies reacted with two groups of proteins the molecular weights of which were estimated to 34-38 and 62 kilodaltons (anti-Yo antibodies). Complementary investigations revealed a tubar adenocarcinoma in the first case, an ovarian carcinoma in the second. The tubar tumoral cells also contained the protein of the highest molecular weight. Compared to the serum, the CSF contained a higher proportion of anti-Yo antibodies per mg IgG, and a fraction of the latter was likely synthesized intrathecally. These antibodies may be involved in the almost total disappearance of the Purkinje cells, as observed at autopsy of both cases.
