Liposomal lipopolysaccharide initiates TRIF-dependent signaling pathway independent of CD14. [PDF]
Lipopolysaccharide (LPS) is recognized by CD14 with Toll-like receptor 4 (TLR4), and initiates 2 major pathways of TLR4 signaling, the MyD88-dependent and TRIF-dependent signaling pathways.

Viral RNA or bacterial products can activate glomerular mesangial cells via a subset of Toll-like receptors (Tlr). Because Tlr2-deficient mice were recently found to have attenuated nephrotoxic serum nephritis (NSN), we hypothesized that endogenous Tlr agonists can activate glomerular mesangial cells. Primary mesangial cells from C57BL/6 mice expressed

Absence of TRIF Signaling in Lipopolysaccharide-Stimulated Murine Mast Cells [PDF]
Abstract In macrophages, two signaling pathways, dependent on MyD88 or TIR domain-containing adaptor-inducing IFN-β (TRIF) signaling, emanate from the LPS receptor TLR4/MD-2. In this study, we show that in murine bone marrow-derived mast cells (BMMCs), only the MyD88-dependent pathway is activated by LPS.

Reduced expression of TRIF in chronic HBV infected Iranian patients
TRIF is one of the main intracellular adaptor proteins required for TLR3 and 4 signaling. Abnormal gene expression of TRIF may lead to abrogated immune responses against viral infections including hepatitis B infection. The aim of this study was to identify the mRNA levels of TRIF in PBMCs isolated from chronic HBV (CHB) infected patients.mRNA was ...

MyD88-Family Adaptors: Compartmentalised Signalling and Non-Immune Functions. [PDF]
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.

Uncoupling Type I Interferon Benefits From Inflammatory Toxicity: Transformer-Prioritized Precision Agonists for Potent and Safer Cancer Immunotherapy. [PDF]
A Transformer‐based AI framework, DLINP, screens millions of compounds to identify Co68, a cobalt‐pincer organometallic complex that biases TLR4‐MD2 signaling toward antitumor interferon activation while suppressing inflammatory toxicity through an early TLR4‐SYK‐STAT1 axis.

Synthetic Toll-Like Receptors for Control of Innate Immunity With Far-Red Light. [PDF]
Synthetic Toll‐like receptors (TLRs) are engineered by replacing their natural sensing regions with a far‐red‐light‐responsive module from a bacterial phytochrome. These synthetic receptors enable light‐controlled regulation of immune signaling in mammalian cells.

A TRIF-Independent Branch of TLR3 Signaling [PDF]
Abstract dsRNA is a common pathogen-associated molecular pattern that is recognized by cellular TLR3 and used by virus-infected cells to activate specific transcription factors and trigger induction of antiviral genes. In this article, we report a new branch of TLR3 signaling that does not lead to gene induction but affects many ...

Dissociation of TRIF bias and adjuvanticity
Toll-like receptors (TLRs), a family of "pattern recognition receptors," bind microbial and host-derived molecules, leading to intracellular signaling and proinflammatory gene expression. TLR4 is unique in that ligand-mediated activation requires the co-receptor myeloid differentiation 2 (MD2) to initiate two signaling cascades: the MyD88-dependent ...

TRIF, and TRIF-Interacting TLRs Differentially Modulate Several Adenovirus Vector-Induced Immune Responses [PDF]
The use of Adenovirus (Ad)-based vectors has proven to be a useful platform for the development of gene therapy and vaccine protocols. The immunological mechanisms underlying these properties need to be identified and understood to foster safer, more efficacious use of this important gene transfer platform.
