Studies on interferon (IFN) induction and isolation of IFN-inducing mutant viruses [PDF]

, 2011
The interferon (IFN) system is a powerful antiviral defense system. Host cell pattern recognition receptors (PRRs) recognise pathogen-associated molecule patterns (PAMPs) which when activated, lead to the transcription of the IFN-β gene. As a consequence

Rotavirus capping enzyme VP3 inhibits interferon expression by inducing MAVS degradation during viral replication

mBio, 2023
The binding of viral RNA to RIG-I-like receptors triggers the formation of mitochondrial antiviral signaling (MAVS) protein aggregates critical for interferon (IFN) expression.

Interferon regulatory factor 1 (IRF-1) promotes intestinal group 3 innate lymphoid responses during Citrobacter rodentium infection

Nature Communications, 2022
Innate lymphoid cells (ILC) are involved with different immune responses. Here the authors show that Interferon regulatory factor 1 (IRF1) is important for intestinal ILC3 accumulation during Citrobacter rodentium infection and promotes release of the ...

Key role of splenic myeloid DCs in the IFN-alphabeta response to adenoviruses in vivo [PDF]

, 2008
The early systemic production of interferon (IFN)-alphabeta is an essential component of the antiviral host defense mechanisms, but is also thought to contribute to the toxic side effects accompanying gene therapy with adenoviral vectors.

Differential Cellular Sensing of Fusion from within and Fusion from without during Virus Infection

Viruses, 2023
The physical entry of virus particles into cells triggers an innate immune response that is dependent on both calcium and nucleic acid sensors, with particles containing RNA or DNA genomes detected by RNA or DNA sensors, respectively.

Viral interferon antagonists and antiviral drugs [PDF]

, 2009
For this project, we developed reporter cell lines that express viral proteins with the potential to be used in cell-based screening assays to select chemical candidates for antiviral drugs.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Interferon regulatory factor 3 plays an anti-inflammatory role in microglia by activating the PI3K/Akt pathway

Journal of Neuroinflammation, 2011
Background Microglia are the principal cells involved in the innate immune response in the CNS. Activated microglia produce a number of proinflammatory cytokines implicated in neurotoxicity but they also are a major source of anti-inflammatory cytokines,

Epigenetic reprogramming of lineage switching in cancer

FEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

Molecular mechanisms of IL-18BP regulation in DLD-1 cells: pivotal direct action of the STAT1/GAS axis on the promoter level [PDF]

, 2008
Interleukin (IL)-18, formerly known as interferon (IFN)-γ-inducing factor, is a crucial mediator of host defence and inflammation. Control of IL-18 bioactivity by its endogenous antagonist IL-18 binding protein (IL-18BP) is a major objective of ...
