FCGR2A and infection: In summary, we investigated GP-specific IgG responses in SUDV infected survivors, and demonstrated that over a decade post-acute disease, GP-specific IgG responses are significant primarily for the IgG1 subclass, and that FcγRI is the prominent FcγR associated with binding of the GP-specific IgGs in these survivors, from acute-infection to more than a decade post infection.
