A preprint abstract from biorxiv.org discusses the potential use of complement therapeutic Factor H-IgG proteins as pre-exposure prophylaxes against Lyme borreliae infections. Lyme disease is a common vector-borne disease caused by Borrelia burgdorferi bacteria, and currently, there is no effective prevention available. The bacteria evade the host immune defense by producing outer surface proteins that bind to a host complement inhibitor. The study produced two chimeric proteins, FH-Fc, which were found to kill B. burgdorferi in the presence of complement and reduce bacterial colonization and joint inflammation in vivo. The researchers demonstrated the concept of using FH-Fc constructs to kill Lyme borreliae and defined underlying mechanisms, suggesting the potential of FH-Fc as a pre-exposure prophylaxis against Lyme disease.
