Antibodies against a neuron-like (HTB-10 neuroblastoma) cell in children with Tourette syndrome

Abstract

Children with TS have higher median, but not mean, levels of ANAb, as measured by the HTB-10 neuroblastoma cell membrane assay. This assay system identified antibodies in both control and clinical groups and failed to identify a relationship between antibodies and clinical phenotype or one-time markers for streptococcal infection. Further studies are required to define a possible immune-mediated hypothesis for TS.
