Advances in Cytosolic dsRNA Sensing of Viral Infections

Immunology &Cell Biology, EarlyView.
Activation of cytosolic dsRNA sensors by viral infection generates multiple outcomes. dsRNA generated during viral infection, either of viral origin or from endogenous sources, can activate multiple cytosolic dsRNA sensors. Activation of PKR critically induces protein translation shutdown via phosphorylation of eukaryotic translation initiation factor ...

Innate Immune Activation Is a Strong Suppressor of CCL22 and Impedes Regulatory T Cell–Dendritic Cell Interaction

Immunology, EarlyView.
During homeostasis, CCL22 is secreted by dendritic cells (DC), which mediate contacts between regulatory T cells (Treg) and DC to maintain immune balance. Activation of innate immunity via microbes or pattern recognition receptor (PRR) agonists induces the secretion of several soluble factors (e.g., type I and II interferons, IL‐10), which mediate ...

Plasmodium yoelii Uses a TLR3-Dependent Pathway to Achieve Mammalian Host Parasitism

, 2020
International audienceMalaria is associated with complicated immunopathogenesis. In this study, we provide evidence for an unexpected role of TLR3 in promoting the establishment of Plasmodium yoelii infection through delayed clearance of parasitemia in ...

MyD88‐Family Adaptors: Compartmentalised Signalling and Non‐Immune Functions

Immunology, EarlyView.
MyD88‐family adaptors coordinate receptor‐ and compartment‐specific innate immune signalling across plasma membrane and endosomal pathways. At the plasma membrane, TIRAP/MAL supports MyD88‐dependent signalling downstream of TLR2 and TLR4, whereas endosomal TLR7, TLR8 and TLR9 recruit MyD88 directly.

Oncolytic avian reovirus regulates the TLR3-IRF3-IFN-γ-JAK-STAT1 and TLR3-NF-κB-IFN-γ-JAK-STAT1 pathways inducing autophagy in murine melanoma cells [PDF]

Oncolytic avian reovirus (ARV) has been identified as a virus capable of selectively infecting and inducing cell death in various cancer cell lines. This study investigates the role of ARV in activating innate immune responses in B16-F10 murine melanoma ...

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

MyD88 Contributes to TLR3-Mediated NF-κB Activation and Cytokine Production in Macrophages

Cells
Toll-like receptor 3 (TLR3) initiates antiviral and inflammatory responses exclusively through the adaptor protein TRIF (TIR-domain-containing adapter-inducing interferon-β).

R‐Loops Mediated Odontogenic Differentiation of hDPSCs by Activating the cGAS‐STING Pathway Under Inflammatory Microenvironment

Oral Diseases, EarlyView.
ABSTRACT Background R‐Loops are three‐stranded DNA/RNA hybrids implicated in immune responses. Their role in mesenchymal stem cell differentiation, particularly in dental pulp regeneration under inflammation, remains unclear. Methods Rat pulpo‐dentinal complex (PDC) injury models and LPS‐stimulated human dental pulp stem cells (hDPSCs) were used.
