Induction of complement-mediated lysis of HIV-1 by a combination of HIV-specific and HLA allotype-specific antibodies.

abstract：:Pathogens in general and pathogenic viruses in particular have evolved a myriad of mechanisms to escape the immune response of mammalian species. Viruses that cause acute disease tend to bear characteristics that make them very contagious, as survival does not derive from chronicity of infection, but spread of disease...
