title: Fcgbp - A Potential Viral Trap in RV144.
abstract: Years of extensive research have yielded much knowledge in many aspects of HIV-1 infection, treatments, and education. However, without a vaccine, the number of people infected worldwide continues to grow. The partial success of the Thai RV144 vaccine trial provides hope that a method of protection is indeed possible. Understanding the mechanism behind the protection is critical if we hope to achieve our goal of inhibiting new infections of HIV-1. We hypothesize that the Fc of IgG binding protein (Fcgbp) is associated with the protection observed in the RV144 vaccine trial. It has the ability to trap viral-antibody complexes in the mucosa by binding the Fc of IgG to Fcgbp. This property could be used in the form of a microbicide containing antibodies to a variety of HIV-1 epitopes to prevent sexual transmission of HIV-1. The aim of this paper is to stimulate further research into Fcgbp and its role in innate immunity.
