Pre-incubation of cell-free HIV-1 group M isolates with non-nucleoside reverse transcriptase inhibitors blocks subsequent viral replication in co-cultures of dendritic cells and T cells. [PDF]

, 2005
In order to study the inhibitory effect of various reverse transcriptase inhibitors (RTIs) on cell-free HIV, we adapted a recently described in vitro system, based on co-cultures of dendritic cells and resting CD4 T cells, modelling early target cells ...

The ALS‐associated E425K mutation uncouples DNAJC7 from the Hsp70 chaperone cycle

The FEBS Journal, EarlyView.
DNAJC7 is a J‐domain protein that plays a key role in protein quality control by regulating Hsp70 activity and preventing protein aggregation. We find that the ALS‐associated E425K mutation in DNAJC7 disrupts productive interaction and activation of Hsp70, thereby blocking the transfer and refolding of client proteins such as TDP‐43.

Optimal infectivity in vitro of human immunodeficiency virus type 1 requires an intact nef gene [PDF]

Journal of Virology, 1994
The replication competence of human immunodeficiency virus type 1 genomes containing mutations in the nef open reading frame was evaluated in continuous cell lines. Mutants that contained a deletion in the nef open reading frame, premature termination codons, or missense mutations in the N-terminal myristoylation signal were constructed.

Vaccine-induced immune responses against both Gag and Env improve control of simian immunodeficiency virus replication in rectally challenged rhesus macaques.

PLoS Pathogens, 2017
The ability to control lentivirus replication may be determined, in part, by the extent to which individual viral proteins are targeted by the immune system.

Immune non‐response despite effective antiretroviral therapy in people living with HIV: A review of potential mechanisms, biomarkers and therapeutic approaches

HIV Medicine, EarlyView.
Abstract Introduction A proportion of people living with HIV (PLWH) fail to restore their CD4 count or their CD4/CD8 ratio despite effective antiretroviral therapy (ART). PLWH with immune non‐response (INR) are at a higher risk of both AIDS and non‐AIDS events. The underlying mechanisms of INR remain unclear.

Sex Differences in Response to Viral Vector Vaccines—Implications for Future Vaccine Design

Immunological Reviews, Volume 338, Issue 1, March 2026.
ABSTRACT Vaccination represents one of the most impactful public health achievements, preventing 3.5 to 5 million deaths annually according to estimates of the World Health Organization. Yet, recent outbreaks of emerging and reemerging infectious diseases highlight the need for rapid and strategic vaccine development using vaccine platforms ...

Impacts of Humanized Mouse Models on the Investigation of HIV-1 Infection: Illuminating the Roles of Viral Accessory Proteins in Vivo

Viruses, 2015
Human immunodeficiency virus type 1 (HIV-1) encodes four accessory genes: vif, vpu, vpr, and nef. Recent investigations using in vitro cell culture systems have shed light on the roles of these HIV-1 accessory proteins, Vif, Vpr, Vpu, and Nef, in ...

Engineering and Validation of a Vector for Concomitant Expression of Rare Transfer RNA (tRNA) and HIV-1 nef Genes in Escherichia coli. [PDF]

PLoS ONE, 2015
Relative ease in handling and manipulation of Escherichia coli strains make them primary candidate to express proteins heterologously. Overexpression of heterologous genes that contain codons infrequently used by E. coli is related with difficulties such

Predominance of weakly cytotoxic, T-betLowEomesNeg CD8+ T-cells in human gastrointestinal mucosa: implications for HIV infection. [PDF]

, 2017
The gastrointestinal mucosa is an important site of HIV acquisition, viral replication, and pathogenesis. Immune cells in mucosal tissues frequently differ in phenotype and function from their non-mucosal counterparts.

Effectiveness of Multivitamins vs Folic Acid on Prevention of Neural Tube Defects in Mouse Genetic Models and Human Organoids

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Folic acid (FA) and multivitamins/minerals (MVM) are recommended for the prevention of neural tube defects (NTDs). Using a novel human neural tube‐like organoid system and mouse models, the study compares the effectiveness of two supplements on NTDs and cellular behaviors.
