Understanding how adenoviruses transduce cells is important for their use and development as vaccine vectors. Adenovirus type 5 (Ad5) is known to bind coagulation factor X (FX), and FX is thought to act as a bridge between the virus and its receptor on hepatocytes. Andrew Byrnes and his colleagues now report that the major role of FX binding to Ad5 is actually to protect Ad5 from neutralization by complement and natural antibodies, and in the absence of B cells, Ad5 does not require FX binding for effective liver transduction.
