HIV-1 Variable Loop 2 and its Importance in HIV-1 Infection and Vaccine Development

Evaluation of clinical course and laboratory findings in HIV/HTLV-1 co-infection compare with HIV mono infection

Background: In the last 10 years, co-infection of human immunodeficiency virus/human T-cell leukemia virus-1 (HIV/HTLV-1) has emerged as a worldwide health problem. These viruses has the same route to infect human but different effects on CD4 positive T-cells. There was controversial results about the influence of co-infection HIV/HTLV-1 pathogenesis. This study compared clinical course and lab...

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...

Response: HIV-2 and Natural Protection Against HIV-1 Infection.

Molecular Epidemiology of HIV-1 in Afghanistan, Iran, and Pakistan

We conducted this study to obtain a comprehensive picture of molecular epidemiology of HIV-1 in three neighboring countries, i.e. Afghanistan, Iran, and Pakistan as a basis for discussing possible hypothesis regarding between-country virus transmission. Our results showed that subtype composition differs between these countries with more variation in Pakistan than Iran and Afghanistan. The CRF3...

An HIV-1 Mini Vaccine Induced Long-lived Cellular and Humoral Immune Responses

Memory formation is the most important aspect of a vaccine which can guarantee long-lasting immunity and protection. The main aim of the present study was to evaluate the memory immune responses after immunization with a mini vaccine. Mice were immunized with human immunodeficiency virus-1 P24-Nef fusion peptide and then cellular and humoral immune responses were evaluated. In order to determin...
