NIR‐II Responsive Multifunctional Scaffold Enabling “Kill‐Modulation‐Build” Synergistic Therapy for Infectious Bone Defects

Advanced Science, EarlyView.
A novel multifunctional scaffold with photothermal effects is developed for infected bone defect repair. It facilitates angiogenesis and osteogenesis while eliminating bacteria through hyperthermia. Additionally, the scaffold promotes macrophage polarization from M1 to M2 via ROS scavenging, enhancing anti‐inflammatory activity. This study demonstrates

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

, 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.

The parasitic worm product ES-62 up-regulates IL-22 production by γδ T cells in the murine model of Collagen-Induced Arthritis [PDF]

, 2014
S-62 is a phosphorylcholine (PC)-containing glycoprotein secreted by the filarial nematode Acanthocheilonema viteae that acts to modulate the host immune response to promote the establishment of chronic helminth infection.

Curcumin Mitigates Neuro-Inflammation by Modulating Microglia Polarization Through Inhibiting TLR4 Axis Signaling Pathway Following Experimental Subarachnoid Hemorrhage

Frontiers in Neuroscience, 2019
Subarachnoid hemorrhage (SAH) elicits destruction of neuronal cells and neurological function, which is exacerbated by neuro-inflammation in EBI, and toll-like receptor 4 (TLR4) plays an important role in inflammatory cascade via modulation microglia ...

Polysaccharide Adjuvants as Innate Immune Trainers: Bridging Pattern Recognition Receptor (PRR) Activation and Metabolic Reprogramming for Synthetic Vaccine Design

Advanced Science, EarlyView.
Polysaccharides modulate immune responses by engaging pattern recognition receptors (PRRs) to induce T‐cell activation. In vaccine design, their particle size critically influences lymph node targeting and activation mechanisms. By engineering structural complexity and multivalent PRR engagement, polysaccharides enable precise modulation of immune ...

Increased NFκ-B Activity in HCT116 Colorectal Cancer Cell Line Harboring TLR4 Asp299Gly Variant [PDF]

, 2012
Toll-Like Receptor 4 (TLR4), considered one of the most important TLR, recognizes lipopolysaccharide of gram-negative bacteria. Recognition of ligands by TLRs induces signaling pathways resulting in activation of transcriptional factors such as NF-κB ...

Endothelial TLR4 and the microbiome drive cerebral cavernous malformations

Nature, 2017
Cerebral cavernous malformations (CCMs) are a cause of stroke and seizure for which no effective medical therapies yet exist. CCMs arise from the loss of an adaptor complex that negatively regulates MEKK3–KLF2/4 signalling in brain endothelial cells, but

Maintenance of homeostasis by TLR4 ligands

Frontiers in Immunology
Immunotherapy is renowned for its capacity to elicit anti-infective and anti-cancer effects by harnessing immune responses to microbial components and bolstering innate healing mechanisms through a cascade of immunological reactions. Specifically, mammalian Toll-like receptors (TLRs) have been identified as key receptors responsible for detecting ...
