Ribonucleotides Amplify Mitochondrial DNA‐Driven cGAS–STING Activation via FdUMP‐ribonucleotide Hybrid Particles to Potentiate Chemoimmunotherapy

Advanced Science, EarlyView.
This work develops a metabolic sharing strategy that employs cytidine monophosphate (CMP) to competitively reprogram floxuridine (FUDR) pyrimidine metabolism in colorectal tumor cells. Elevated intracellular FdUMP induces nucleotide imbalance, drives mitochondrial DNA release and cGAS‐STING innate immune cascade activation, and potentiates robust ...

Defective interfering particles of parainfluenza virus subtype 5 and interferon induction [PDF]

, 2015
The innate immune response is the first line of defence against virus infection. Cells contain a diverse array of pathogen recognition receptors (PRRs) that are able to recognise multiple pathogen associated molecular patterns (PAMPS) that present ...

TP53 Loss Elevates NF‐κB‐IFN‐β‐MHC‐Ia Signaling to Promote NK Cell Resistance in Osteosarcoma

Advanced Science, EarlyView.
TP53 loss in a transforming or osteosarcoma cell promotes cytosolic DNA accumulation, activating NF‐κB‐dependent IFN‐β production. Autocrine IFN‐β signaling increases cell‐surface HLA‐Ia expression, strengthens inhibitory KIR signaling in natural killer cells, and thereby enables the affected cell to evade NK cell‐mediated cytotoxicity.

Activation of the interferon induction cascade by influenza A viruses requires viral RNA synthesis and nuclear export [PDF]

, 2014
This work is supported by grants from the Wellcome Trust (grants 087751/A/08/Z) and MRC (G1001726/1).We have examined the requirements for virus transcription and replication and thus the roles of input and progeny genomes in the generation of interferon

Sonogenetics Nanomedicine Activates the cGAS‐STING Pathway for Immunotherapy of Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
A HER3‐targeted sonogenetic lipid nanoparticle platform is developed for triple‐negative breast cancer therapy. An AI‐designed miniprotein inhibits HER3 signaling, while TRPV4 and NFAT‐responsive IL‐15 plasmids enable ultrasound‐controlled calcium signaling and cytokine expression. The system induces Ca2+ overload, ROS generation, mitochondrial damage,

Glutaminolysis Blockade‐Empowered Bimodal Nanodepot for Spatially Complementary Sono‐Thermal Ablation via PANoptosis and STING Activation Against Large Tumors

Advanced Science, EarlyView.
An injectable bimodal TCPD nanodepot disrupts glutaminolysis and TCA metabolism, sensitizing large tumors to spatially complementary sono‐thermal ablation for complete treatment coverage. This intervention induces mitochondrial and endoplasmic reticulum dysfunction, genotoxicity, and NAD+ depletion, converging to trigger PANoptosome assembly and ...

Induction of Noxa-mediated apoptosis by modified vaccinia virus Ankara depends on viral recognition by cytosolic helicases, leading to IRF-3/IFN-β-dependent induction of pro-apoptotic Noxa. [PDF]

, 2011
Viral infection is a stimulus for apoptosis, and in order to sustain viral replication many viruses are known to carry genes encoding apoptosis inhibitors. F1L, encoded by the orthopoxvirus modified vaccinia virus Ankara (MVA) has a Bcl-2-like structure.

Biochemical Analysis of Caspase-8-dependent Proteolysis of IRF3 in Virus-infected Cells

Bio-Protocol, 2016
Interferon regulatory factor 3 (IRF3) is a transcription factor, which is critical for the antiviral response against a wide range of viruses (Hiscott, 2007; Ikushima et al., 2013). It gets activated in virus-infected cells via Toll like receptors (TLRs),

The role of NSP1 in rotavirus pathogenesis [PDF]

NSP1, a non-structural protein encoded by rotavirus gene segment 5, has been suggested as a virulence determinant for rotavirus and to function as an antagonist of the interferon signalling pathway.
