Dideoxynucleosides are less inhibitory in vitro against human immunodeficiency virus type 2 (HIV-2) than against HIV-1

Dideoxynucleosides are less inhibitory in vitro against human immunodeficiency virus type 2 (HIV-2) than against HIV-1.

The antiviral activities of various dideoxynucleosides against LAV strains of human immunodeficiency viruses type 1 (HIV-1) and type 2 (HIV-2) were evaluated. Significantly more 3'-azido-3'-deoxythymidine was required to inhibit the replication of HIV-2 than HIV-1 in three human cell lines. HIV-2 also appeared more resistant than HIV-1 to other dideoxynucleosides. These results suggest that did...

In vitro Assessment of Antiviral Activity of Cold Atmospheric Pressure Plasma Jet against the Human Immunodeficiency Virus (HIV)

Introduction: The human immunodeficiency virus (HIV) is a threat to global health and the need for finding new methods of antivirus research, in particular against HIV has increased in recent years. In this study, we investigated the ability of the cold atmospheric pressure plasma jet (CAPPJ) using helium to inhibit the replication of HIV virions. Methods: Single cycle replicable HIV (SCR-HIV) ...

MOLECULAR BIOLOGY OF HUMAN IMMUNODEFICIENCY VIRUSES: HIV-l AND HIV-2

No Role of Herpes Simplex Virus Type 2 (HSV-2) Infection on HIV Progression in Naïve HIV Patients

Background: Herpes simplex virus type 2 (HSV-2) is a common infection in human immunodeficiency virus (HIV) patients and may accelerate HIV progression by rising HIV viral load and decreasing CD4 count. However, the available data regarding the influence of HSV-2 seropositivity on HIV progression in HIV individuals are inconclusive. Therefore, we aimed to determine HSV-2 seroprevalence in na&iu...

Frequency of Human T-Cell Lymphotropic Virus (HTLV) Type 1 and 2 Infection in HIV Infected Patients

Background and Objectives: Human T-cell lymphotropic viruses (HTLV) type 1 and 2 are retroviruses that share the same routes of transmission as human immunodeficiency virus (HIV). As a consequence of epidemiologic similarities, HIV and HTLV-1/2 co-infection is frequent. Due to the limited data, this study assessed the seroprevalence of HTLV-1/2 infections in HIV infected patients in Tehran, Ira...
