The Functional Mechanisms of Toll-Like Receptor 3 and Its Implications in Digestive System Tumors
Frontiers in Bioscience-Landmark, 2023 Toll-like receptor 3 (TLR3) is a prominent member of the Toll-like receptor (TLR) family and has the ability to recognize and bind intracellular double-stranded RNA (dsRNA).

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.

Hypothesized TLR3 RNA-sensing system.
, 2014 (A) Extracellular dsRNA binds SR-A or raftlin on cell surface and enters via endocytosis. (B) SR-A communicates a negative signal to endosomal TLR3, which binds dsRNA and induces TNF-α production via TRIF.

EMBO Molecular Medicine, 2014 RNA‐sensing toll‐like receptors (TLRs) mediate innate immunity and regulate anti‐viral response. We show here that TLR3 regulates host immunity and the loss of TLR3 aggravates pathology in Chikungunya virus (CHIKV) infection.

Dual‐Targeted Biomimetic MoSe2 Nanozymes for Enhancing Peri‐Implant Soft Tissue Integration
Advanced Science, EarlyView.A dual‐targeting biomimetic nanozyme, MoSe2@SPMM, selectively targets Staphylococcus aureus and oxidatively stressed macrophages. Near‐infrared activation couples contact‐enhanced photothermal bacterial eradication with reactive oxygen species scavenging to disrupt the pathogenic–immunological amplification loop.

Advanced Science, EarlyView.Human vellus pilosebaceous units (PSUs) remain uncharted. This single‐nucleus atlas reveals coordinated remodeling of the aging PSU niche: reduced bulge stem cell representation with altered regenerative programs, increased representation of a stress‐responsive channel+ epithelial state, enhanced androgen‐responsive sebaceous programs, reduced ...

Toll like receptor 3 plays a critical role in the progression and severity of acetaminophen-induced hepatotoxicity. [PDF]
PLoS ONE, 2013 Toll-like receptor (TLR) activation has been implicated in acetaminophen (APAP)-induced hepatotoxicity. Herein, we hypothesize that TLR3 activation significantly contributed to APAP-induced liver injury.

A Fish MDA5 Integrates Canonical RIG‐I and MDA5 Ligand Recognition
Advanced Science, EarlyView.These results show that the large yellow croaker lacks RIG‐I, yet its MDA5 senses both 5′ppp‐dsRNA and long dsRNA. A flexible RNA‐capping loop in the MDA5 C‐terminal domain enables two ligand‐binding modes. This dual recognition signals through MAVS–STING–TBK1/IRF3 and induces type I interferons, revealing unexpected plasticity in vertebrate antiviral ...

TLR3 impairment in human newborns
, 2013 Newborns are highly susceptible to viral infections. We hypothesized that this susceptibility could be due to a dysregulated expression of innate virus-sensing receptors, i.e., TLR3, TLR7, TLR8, and TLR9 and the cytosolic receptors retinoic acid ...
