Weak anti-HIV CD8(+) T-cell effector activity in HIV primary infection.
HIV-specific CD8(+) T cells play a major role in the control of virus during HIV primary infection (PI) but do not completely prevent viral replication. We used IFN-gamma enzyme-linked immunospot assay and intracellular staining to characterize the ex vivo CD8(+) T-cell responses to a large variety of HIV epitopic peptides in 24 subjects with early HIV PI. We observed HIV-specific responses in ...
متن کاملT-cell Depletion in Human Immunodeficiency Virus (HIV) - 1 Infection
In this review, immune response and possible causes of depletion of CD4 + T-cell counts in patients with human immunodeficiency (HIV)-1 infection, have been documented. HIV has been recognized as a global problem; however, the developing countries are the most affected by epidemic diseases. Countries in the sub-Saharan Africa seem to bear the bulk of the HIV burden among the developing countrie...
متن کاملCytomegalovirus Active Infection in Persons Infected with Human Immunodeficiency Virus
Background and Objective: Cytomegalovirus (CMV), one of the most common opportunistic pathogens in patients infected with human immunodeficiency virus (HIV), can cause the diseases such as encephalitis, pneumonia, and chorioretinitis. This study aimed at molecular studying of CMV infection in individuals infected with the human immunodeficiency virus. Material and Methods: In this study, 50 ven...
متن کاملVirus-specific CD8+ cytotoxic T-lymphocyte activity associated with control of viremia in primary human immunodeficiency virus type 1 infection.
Human immunodeficiency virus type 1 (HIV-1) Env-, Gag-, Pol-, Nef-, and Tat-specific cytotoxic T-lymphocyte (CTL) activities were quantitated temporally in five patients with symptomatic primary HIV-1 infection. A dominant CD8(+)-mediated, major histocompatibility complex class I-restricted CTL response to the HIV-1 envelope glycoprotein, gp160, was noted in four of the five patients studied. T...
متن کاملFrequency 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...
