Novel mutations in the toll like receptor genes cause hyporesponsiveness to Mycobacterium avium subsp. paratuberculosis infection [PDF]

open access: yes, 2008
Toll like receptors play a central role in the recognition of pathogen associated molecular patterns (PAMPs). Mutations in TLR1, TLR2 and TLR4 genes may change the PAMP reorganization ability which causes altered responsiveness to the bacterial pathogens.

A Pancreatitis‐Inspired Trypsinogen Nanoplatform Reprograms Tumor‐Associated Macrophages via NF‐κB for Pancreatic Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
Trypsinogen‐loaded nanoparticles reprogram TAMs via NF‐κB/NLRP3, driving M2→M1 conversion and potent phagocytosis to unleash antitumor immunity. ABSTRACT Although reprogramming tumor‐associated macrophages (TAMs) represents a promising therapeutic strategy, approaches that are both precise and safe remain scarce.

Responsiveness of human TLR2 (N657E), TLR2 (L663E) and TLR2 (N688A) to TLR2/2, TLR2/1 and TLR2/6 agonists.

open access: yes, 2013
HEK293T cells in 24-well plates were transfected with human TLR2 (N657E), TLR2 (L663E) or TLR2 (N688A), and TK-RL and pBIIx-luc. At 24 h post-transfection, the cells were stimulated with the indicated concentrations of LTA (A), Pam3CSK4 (B) and FSL (C ...

Activation of Ca2+-Dependent Signaling by TLR2 [PDF]

open access: yesThe Journal of Immunology, 2006
Abstract Upon contact with airway epithelial cells, bacterial products activate Ca2+ fluxes that are required for induction of NF-κB-dependent gene expression. TLR2 is apically displayed on airway cells, making it a likely transducer linking bacterial stimuli and kinases that affect Ca2+ release. Using biochemical and genetic approaches,

Biomimetic Nanoplatform for Dual Target Nano‐Metabolic Therapy in Diabetes‐Associated Biofilm Infections

open access: yesAdvanced Science, EarlyView.
A biomimetic GOx/Arg‐loaded nanoplatform produces nitric oxide through an in situ catalytic cascade reaction, enabling dual‐target metabolic regulation in diabetes‐associated biofilm infections. Bacterial metabolism is disrupted, and macrophage immunometabolism is reprogrammed, resulting in biofilm eradication, immune restoration, and enhanced ...

TLR2-responsive JMJD3 regulates mycobacteria-induced FM formation and immune responses.

open access: yes, 2016
(A and B) Mouse peritoneal macrophages were infected with the indicated bacteria (H37Ra: M. tuberculosis H37Ra; BCG: M. bovis BCG; MS: M. smegmatis) for 6 h. Immunoblot analysis for H3K27me3, EZH2 and JMJD3 (A) and quantitative real-time RT-PCR for Jmjd3

Crosstalk between NOD2 and TLR2 suppresses the development of TLR2-mediated experimental colitis

open access: yesJournal of Clinical Biochemistry and Nutrition
Nucleotide-binding oligomerization domain 2 (NOD2) is an intracellular sensor for muramyl dipeptide (MDP), a degradation product of bacterial cell wall peptidoglycan (PGN). PGN stimulates cell-surface Toll-like receptor 2 (TLR2) independently of NOD2, indicating the presence of crosstalk between extracellular TLR2 and intracellular NOD2 upon exposure ...

Membrane‐Active Peptide Protects Against Inflammation by Targeting NLRP3 Activation at the Trans‐Golgi Network

open access: yesAdvanced Science, EarlyView.
The membrane‐active peptide Pep19‐2.5 reduces harmful inflammation by blocking activation of the NLRP3 inflammasome at trans‐Golgi network membranes. By targeting key membrane interactions, Pep19‐2.5 suppresses inflammatory IL‐1β production and alleviates allergic airway inflammation in mice, leading to reduced immune cell infiltration and improved ...

A Review: The Significance of Toll-Like Receptors 2 and 4, and NF-κB Signaling in Endothelial Cells during Atherosclerosis

open access: yesFrontiers in Bioscience-Landmark
Atherosclerosis (AS) is a chronic inflammatory vascular disease that begins with endothelial activation followed by a series of inflammatory responses, plaque formation, and finally rupture.
