Common Themes of Antibody Maturation to Simian Immunodeficiency Virus, Simian-Human Immunodeficiency Virus, and Human Immunodeficiency Virus Type 1 Infections

Cross-neutralization of human immunodeficiency virus type 1 and 2 and simian immunodeficiency virus isolates.

In contrast to infrequent and low-titer cross-neutralization of human immunodeficiency virus type 1 (HIV-1) isolates by HIV-2- and simian immunodeficiency virus (SIV)-positive sera, extensive cross-neutralization of HIV-2NIH-Z, SIVMAC251, and SIVAGM208K occurs with high titer, suggesting conservation of epitopes and mechanism(s) of neutralization. The V3 regions of HIV-2 and SIV isolates, minim...

Simian immunodeficiency virus RNA is efficiently encapsidated by human immunodeficiency virus type 1 particles.

Packaging of retroviral RNA is attained through the specific recognition of a cis-acting encapsidation site (located near the 5' end of the viral RNA) by components of the Gag precursor protein. Human immunodeficiency virus type 1 (HIV-1) and simian immunodeficiency virus (SIV) are two lentiviruses that lack apparent sequence similarity in their putative encapsidation regions. We used SIV vecto...

Virus-Induced IL-2 Expression by Central Virus/Simian Human Immunodeficiency Dysfunction of Simian Immunodeficiency

Broadly Neutralizing Human Immunodeficiency Virus Type 1 Antibody Gene Transfer Protects Nonhuman Primates from Mucosal Simian-Human Immunodeficiency Virus Infection.

Broadly neutralizing antibodies (bnAbs) can prevent lentiviral infection in nonhuman primates and may slow the spread of human immunodeficiency virus type 1 (HIV-1). Although protection by passive transfer of human bnAbs has been demonstrated in monkeys, durable expression is essential for its broader use in humans. Gene-based expression of bnAbs provides a potential solution to this problem, a...

Distribution of Epstein-Barr Virus and Human Herpesvirus 8 Co-Infections among Human Immunodeficiency Virus -1 Positive Patients

Background and Aims: Among Human Immunodeficiency Virus (HIV)-infected individuals, Epstein-Barr virus (EBV) and Human Herpesvirus (HHV)-8 could cause significant illness as opportunistic infections. The purpose of the present study was to evaluate the prevalence of EBV and HHV-8 in saliva specimens obtained from HIV-1 infected Iranian individuals under the Highly Active Antiviral Therapy (HAAR...
