A new diagnostic tool for neurocysticercosis is a member of a cestode specific hydrophobic ligand binding protein family.

A protein of unknown function has been identified as a key serological tool for diagnosis of human tapeworm neurocysticercosis, a major worldwide neurological disease. Our own sequence analysis predicts that this protein is a member of a newly identified cestode specific oligomeric hydrophobic ligand binding protein family. In this report, using a rat cestode model, we confirm that homologues of this protein can bind fatty acids and their derivatives, and thus suggest a biological function for this key diagnostic tool.
