Molecular Chaperone Networks in Plants: Maintaining Proteostasis and Enhancing Stress Resilience for Crop Improvement

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Molecular chaperones play a central role in the plant proteostasis machinery by aiding the folding of nascent proteins, preventing aggregation, and repairing or degrading damaged proteins. These functions are especially essential during abiotic and biotic stress, which can destabilise cellular proteins and disrupt metabolic homoeostasis.

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

open access: yesPLoS 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.

Single‐Nucleus Multiomic Analysis Reveals Immune–Metabolic Reprogramming Consistent With Maladaptive Trained Immunity in HIV‐Associated Neurocognitive Disorders

open access: yesGlia, Volume 74, Issue 8, August 2026.
Single‐nucleus multiomic profiling of postmortem brain reveals coordinated immune, metabolic, and epigenomic reprogramming in glia of people with HIV consistent with maladaptive trained immunity sustaining neuroinflammation in HAND. ABSTRACT HIV‐associated neurocognitive disorders (HAND) remain prevalent in people with HIV (PWH) despite effective ...

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

open access: yesFEBS Letters, Volume 600, Issue 14, Page 2028-2037, July 2026.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...

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

open access: yesViruses, 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]

open access: yesPLoS 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

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

open access: yesFEBS Open Bio, Volume 16, Issue 7, Page 1293-1304, July 2026.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Deletion, insertion and stop codon mutations in vif genes of HIV-1 infecting slow progressor patients

open access: yesJournal of Infection in Developing Countries, 2009
Background: Variable progression towards AIDS has been described and has been related to viral and host factors. Around 10% of the HIV-1 infected patients are slow progressors (SP), not presenting with AIDS disease signs even after more than 10 years of ...

Phylogenetic Analysis of the Earliest nef Gene from Hemophiliacs and Local Controls in Korea

open access: yesBioResearch Open Access, 2012
Twenty hemophiliacs (HPs) were found to have human immunodeficiency virus type-1 (HIV-1) 1-2 years after exposure to Factor IX manufactured in Korea in late 1989. Plasma samples collected from donors O and P during their pre-seroconversion acute infection stage were used to manufacture clotting factors, including Factor IX, to treat these patients.

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

open access: yesAdvanced Science, Volume 13, Issue 42, 28 July 2026.
This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...
