HIV-1-specific CTLs effectively suppress replication of HIV-1 in HIV-1-infected macrophages.
Both CD4+ T cells and macrophages are major reservoirs of HIV-1. Previous study showed that HIV-1-specific cytolytic T lymphocytes (CTLs) hardly recognize HIV-1-infected CD4+ T cells because of Nef-mediated HLA class I down-regulation, suggesting that HIV-1 escapes from HIV-1-specific CTLs and continues to replicate in HIV-1-infected donors. On the other hand, the CTL recognition of HIV-1-infec...
متن کاملSLCO2B1 gene polymorphism and anti-retroviral therapy side effects in HIV-1 infected patients
Abstract Background and Objectives HIV virus and its subsequent disease is one of the most important challenges of the world health system. Although antiretroviral therapy (ART) is a breakthrough in patients’ life quality, it has complications like side effects. The side effect causes are diverse. One of the factors considered about side effects is genes polymorphism. This study investigates th...
متن کاملA Simple and Rapid Method for the Detection of HIV-1/HCV in Co-Infected Patients
Background: Due to some limitations of serological methods in diagnosis of patients infected with HIV-1 (human immunodeficiency virus) and HCV (hepatitis C virus), it is profoundly important to use molecular methods for the detecting of these infectious agents. However, the most significant problems are the exorbitant cost of these methods and the need of a thermocycler which is an expensive...
متن کاملImmune reconstitution in HIV-1-infected patients.
HIV-1-specific CD8 cytotoxic and CD4 helper T-lymphocytes, which are respectively the central effector and regulatory cells in viral infections, together with fully functional antigen-presenting cells, are essential at all stages of HIV-1 infection to control viral activity. Recent studies indicate that such protective HIV-1-specific immune responses can be preserved/induced in HIV-1-infected i...
متن کاملBiased TCR repertoire in HIV-1-infected patients due to clonal expansion of HIV-1-reverse transcriptase-specific CTL clones.
To study whether an expansion of HIV-1-specific CTL is contributing to the skewed TCR repertoire in HIV-1-infection, we characterized the TCR usage of CTL clones specific for a conserved epitope in HIV-1 reverse transcriptase (RT/476-484). CTL clones from three HIV-1-infected patients displayed highly similar TCR usage and used the identical Vbeta6.1 and Valpha2.5 gene segments. CTL clones from...
