Suppression of HIV replication in vitro by CD8+ T-cells from HIV-infected and HIV-seronegative individuals

Abstract

The inhibitory effect of CD8+ T-cells from HIV-infected or HIV-seronegative individuals on HIV replication in the naturally-infected CD4+ T-cells in vitro was examined. Not only autologous CD8+ T-cells from HIV-infected individuals but also allogeneic CD8+ T-cells from HIV-seronegative individuals prevented or delayed HIV replication, even in transwell cocultures using a semi-permeable 0.45 micron filter. The level of the inhibitory effect of allogeneic CD8+ T-cells from the HIV-seronegative individuals on the HIV replication was varied among CD4+ T-cells obtained from HIV-infected individuals used. The results suggested that CD8+ T-cells from HIV-seronegative individuals as well as HIV-infected individuals could produce some cytokine(s) which suppress HIV replication in vitro. The sensitivity to the cytokine(s) might be variable among HIV strains, depending on differences in the nucleotide sequence of different HIV-1 strains. Further studies of control of HIV replication by CD8+ anti-HIV cytokine(s) should provide new strategies for the therapy of HIV infection.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
