Efficient processing of an antigenic sequence for presentation by MHC class I molecules depends on its neighboring residues in the protein [PDF]

, 1991
Processing of endogenously synthesized proteins generates short peptides that are presented by MHC class I molecules to CD8 T lymphocytes. Here it is documented that not only the sequence of the presented peptide but also the residues by which it is ...

The role of histone modifications in transcription regulation upon DNA damage

FEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Neutralization Determinants on Poxviruses

Viruses, 2023
Smallpox was a highly contagious disease caused by the variola virus. The disease affected millions of people over thousands of years and variola virus ranked as one of the deadliest viruses in human history. The complete eradication of smallpox in 1980,

Safety and Efficacy of Adoptive Transfer of Stem Cell Memory Enriched Virus Specific T Cells against CMV and EBV

Advanced Science, EarlyView.
This study finds that CD8⁺ TSCM cells exhibit superior self‐renewal, differentiation, and antiviral activity. Transcriptome and epigenome analyses highlight MAPK cascade regulation in TSCM cells. In vivo, virus‐specific TSCM cells show enhanced persistence and tumor protection.

In-vitro demonstration of cell-mediated immunity to vaccinia virus in man [PDF]

, 1975
Cell mediated immunity to vaccinia virus in man was studied by lymphocyte transformation. Vaccinia antigen, propagated on BHK-21 and Vero cells, could be used successfully for in-vitro testing after partial purification as well as crude infectious ...

Studies on processing, particle formation, and immunogenicity of the HIV-1 gag gene product: a possible component of a HIV vaccine [PDF]

, 1992
Antigens in a particulate conformation were shown to be highly immunogenic in mammals. For this reason, the particle forming capacity of derivatives of the HIV-1 group specific core antigen p55 gag was assayed and compared dependent on various expression

A dsRNA Viral Transcriptional Regulator Evades Innate Immunity by Hijacking Host CoTranscription Factor DHX9

Advanced Science, EarlyView.
This study identifies a new viral mechanism by a viral protein σ3 that functions as a vTR to suppress NF‐κB gene expression via its direct interaction with the host helicase DHX9. Through their interaction, σ3 not only impairs the initial recruitment of Pol II but also affects Pol II pause‐release and ultimately suppresses NF‐κB gene expression ...

Recombinant chimeric horsepox virus (TNX-801) is attenuated relative to vaccinia virus strains in both in vitro and in vivo models

mSphere
Recombinant chimeric horsepox virus (TNX-801) is a preclinical vaccine in development against mpox and smallpox. In this report, we investigated the potential phenotypic differences in in vitro and in vivo models between TNX-801 and older vaccinia virus (

CD20+FCRL4+ B Cells Activate CD8+ T Cells via MHC‐I Restriction in Nasopharyngeal Carcinoma Anti‐Tumor Immunity

Advanced Science, EarlyView.
CD20⁺FCRL4⁺ B cells in nasopharyngeal carcinoma actively cross‐present exogenous tumor antigens via MHC‐I, enhancing CD8⁺ T‐cell activation, memory formation, and cytotoxicity. IFNγ‐driven WDFY4 upregulation facilitates this process. These findings reveal an unconventional B‐cell–mediated antitumor mechanism and indicate potential relevance to ...

Neomycin resistance as a dominant selectable marker for selection and isolation of vaccinia virus recombinants [PDF]

, 1985
The antibiotic G418 was shown to be an effective inhibitor of vaccinia virus replication when an appropriate concentration of it was added to cell monolayers 48 h before infection. Genetic engineering techniques were used in concert with DNA transfection
