Abstract

INTRODUCTION: The abnormal hyperphosphorylation of the microtubule-associated protein tau plays a crucial role in neurodegeneration in Alzheimer's disease (AD) and other tauopathies.

METHODS: Highly specific and selective anti-pS396-tau antibodies have been generated using peptide immunization with screening against pathologic hyperphosphorylated tau from rTg4510 mouse and AD brains and selection in in vitro and in vivo tau seeding assays.

RESULTS: The antibody C10.2 bound specifically to pS396-tau with an IC

DISCUSSION: Targeting pS396-tau with an antibody like C10.2 may provide therapeutic benefit in AD and other tauopathies.
