Messenger RNA-encoded antibody approach for targeting extracellular and intracellular tau

Abstract

Monoclonal antibodies have emerged as a leading therapeutic agent for the treatment of disease, including Alzheimer’s disease. In the last year, two anti-amyloid monoclonal antibodies, lecanemab and aducanumab, have been approved in the USA for the treatment of Alzheimer’s disease, whilst several tau-targeting monoclonal antibodies are currently in clinical trials. Such antibodies, however, are expensive and timely to produce and require frequent dosing regimens to ensure disease-modifying effects. Synthetic in vitro-transcribed mRNA encoding antibodies for endogenous protein expression holds the potential to overcome many of the limitations associated with protein antibody production. Here,..
