Fig. 1From: Anti-neuronal antibodies associated with headache with neurological deficits and cerebrospinal fluid lymphocytosisThe binding pattern of HaNDL patients’ IgG with the rat cerebral and cerebellar nuclei is similar but somewhat distinctive from those of anti-Hu, anti-Ri and ANA positive serum samples (left two columns, original magnification ×100, counterstained with hematoxylin). ANA positive sera react with the nuclei of both the widespread intestinal and HEp-2 cells, anti-Hu positive sera only react with the nuclei of intestinal neuronal cells (arrow) and anti-Ri positive and HaNDL sera do not react with any of these tissues (right two columns, original magnification ×100, immunofluorescence, normal normal serum sample, G granular layer, P Purkinje cells, M molecular layer, ANA anti-nuclear antibody)Back to article page
