Hexameric S100A12 is required for pro-inflammatory TLR4-signalling

چکیده
Introduction The human granulocyte-specific Ca-binding protein S100A12 is particularily over-expressed in autoinflammatory diseases such as juvenile idiopathic arthritis (JIA) as well as other inflammatory conditions (i.e. infections, vasculitides) and has been ascribed to the group of pro-inflammatory damage associated molecular pattern molecules (DAMPs). In order to operate as DAMP, S100A12 requires binding to cellular receptors. Although the protein was originally found to bind the receptor of advanced glycation endproducts (RAGE), we recently demonstrated S100A12 to stimulate proinflammatory cytokine production in monocytes via TLR4 instead of RAGE.

S100A9 gene silencing inhibits the release of pro‐inflammatory cytokines by blocking the IL‐17 signalling pathway in mice with acute pancreatitis
The study aimed to investigate whether S100A9 gene silencing mediating the IL-17 pathway affected the release of pro-inflammatory cytokines in acute pancreatitis (AP). Kunming mice were assigned to the normal, AP, AP + negative control (NC), AP + shRNA, AP + IgG and AP + anti IL-17 groups. ELISA was applied to measure expressions of AMY, LDH, CRP, TNF-α, IL-6 and IL-8. The cells were distribute...

Introduction The granulocyte-specific Ca-binding protein S100A12 is overexpressed during autoinflammation as well as other inflammatory conditions in humans and has been ascribed to the group of pro-inflammatory Damage Associated Molecular Pattern molecules (DAMPs). S100A12-levels in human serum reveal excellent correlation with patients’ inflammation state, which renders S100A12 a powerful bio...
متن کاملThe Damage Associated Molecular Pattern (DAMP) molecule S100A12 induces pro-inflammatory responses in monocytes via innate immunity signalling pathways
Background In a previous study, we demonstrated excessive activation of neutrophils leading to high concentrations of S100A12, a member of the damage-associated molecular pattern molecules (DAMP), in systemic-onset juvenile idiopathic arthritis (SOJIA) which is not found in other inflammatory diseases. Binding to the Receptor for Advanced Glycation Endproducts (RAGE) has been shown but exact mo...
متن کاملThe citrus flavonoid naringenin confers protection in a murine endotoxaemia model through AMPK-ATF3-dependent negative regulation of the TLR4 signalling pathway
Excessive activation of the TLR4 signalling pathway is critical for inflammation-associated disorders, while negative regulators play key roles in restraining TLR4 from over-activation. Naringenin is a citrus flavonoid with remarkable anti-inflammatory activity, but the mechanisms underlying its inhibition of LPS/TLR4 signalling are less clear. This study investigated the molecular targets and ...

NEW FINDINGS What is the central question of this study? What is the functional relevance of OPN isoform expression in muscle pathology? What is the main finding and its importance? The full-length human OPN-a isoform is the most pro-inflammatory isoform in the muscle microenvironment, acting on macrophages and myoblasts in an RGD-integrin-dependent manner. OPN-a upregulates expression of tenas...
