title: Efficacy of an immunoglobulin preparation from HIV carriers in preventing HIV replication in vitro.
abstract: Immunoglobulin samples (HIV-Ig) were prepared by cold ethanol fractionation of human plasma containing antibody against human immunodeficiency virus (HIV). The ability to prevent viral spreading was studied using either human T-cell leukemia virus type I (HTLV-I)-carrying MT-4 cells or in a coculture system using MOLT-4 cells and virus-producing MOLT-4/HIV HTLV-IIIB cells. Treatment of HIV-infected MT-4 cells with HIV-Ig effectively blocked the appearance of antigens of HIV and the virus-induced cytopathic effect. HIV-Ig blocked multinucleated giant cell formation in the MOLT-4 and MOLT-4/HIV HTLV-IIIB coculture system.
