 AB    Human immunodeficiency virus type 1 (HIV-1) seropositive donors
       typically have high serum antibody titers to a range of autoantigens,
       and the corresponding autoantibodies have been suggested to be of
       importance in the pathogenesis of HIV-1 infection. We have prepared 38
       IgG human monoclonal autoantibodies from asymptomatic HIV-1 seropositive
       donors with elevated serum titers to autoantigens by construction of Fab
       combinatorial libraries on the surface of phage and affinity selection
       using a range of autoantigens, including double-stranded DNA, major
       histocompatibility complex class II, CD14, epidermal growth factor
       receptor, and ganglioside GD2. The autoantibodies are shown to be of
       moderate affinity and exhibit marked cross-reactivity with a range of
       antigens. This contrasts with the specific high-affinity antibodies
       selected (i) against infectious agents using the same libraries and (ii)
       against one of the autoantigens using a library from a donor with
       established autoimmune disease. The results lend no support to the
       presence of specific autoantibodies in HIV-1 infection and instead
       suggest attention should be focused on the pathological significance of
       high serum levels of antibodies capable of interacting with multiple
       molecular species.
