CEM-T4 Cells Do Not Lack an APOBEC3G Cofactor
Human APOBEC3G inhibits the replication of Vif-deficient HIV-1 by hypermutating nascent viral cDNA (reviewed in [1– 3]). Zheng and colleagues recently reported that the HIV-1 restriction activity of APOBEC3G requires a cellular co-factor [4]. Their conclusion depended on three critical observations: i) CEM-T4 cells support the replication of Vif-deficient HIV-1, ii) CEM-T4 cells express restric...
متن کاملPoliovirus Particles do not Form in Preinfected Cells with Reovirus
Background and Aims: Inhibition of viral growth in coinfected cells with two different viruses has been described. This phenomenon known as viral interference can occur in several virus host systems such as interference of enterovirus infection on poliovirus vaccine strains. In this study we superinfected reovirus infected HeLa cells with poliovirus to determine if poliovirus can replicate in s...
متن کاملAPOBEC3G and APOBEC3F Require an Endogenous Cofactor to Block HIV-1 Replication
APOBEC3G (A3G)/APOBEC3F (A3F) are two members of APOBEC3 cytidine deaminase subfamily. Although they potently inhibit the replication of vif-deficient HIV-1, this mechanism is still poorly understood. Initially, A3G/A3F were thought to catalyze C-to-U transitions on the minus-strand viral cDNAs during reverse transcription to disrupt the viral life cycle. Recently, it was found more likely that...

متن کاملTST-Negative Individuals Do Not Lack Anti-Mycobacterial Responsiveness
Tuberculin-skin-test (TST) is widely used for the diagnosis of Tuberculosis. Negative TSTs are occasionally found in individuals vaccinated or infected by Mycobacterium tuberculosis. We show that false negative results are due to a lack of the Tuberculin-specific immune response as replacing tuberculin by unselected M. tuberculosis antigens improved the efficiency of the assay. Tuberculosis (TB...
