Abstract
and is a global public health threat. The rabies virus invades and infects cells mainly via a glycoprotein, which may involve multiple receptors. Neutralizing antibodies against the rabies virus function by blocking the binding of the glycoprotein to a receptor or preventing the membrane fusion process. Vaccination combined with anti-rabies virus neutralizing antibodies is essential for postexposure prophylaxis for category III exposure to the rabies virus. In this review, we discussed the neutralizing epitopes of the rabies virus and the neutralization mechanism of monoclonal antibodies. The neutralizing antibodies that have been commercialized or are under development are also summarized. Our review would provide a basis for the further development of safe and effective broad-spectrum neutralizing antibodies to replace the rabies virus immunoglobulin in rabies post-exposure prophylaxis.
