X-linked Inhibitor of Apoptosis (XIAP) deficiency predisposes people to pathogen-associated hyperinflammation. Upon XIAP loss, Toll-like receptor (TLR) ligation triggers RIPK3-caspase-8-mediated IL-1β activation and death in myeloid cells. How XIAP suppresses these events remains unclear. Here, we show that TLR-MyD88 causes the proteasomal degradation of the related IAP, cIAP1, and its adaptor, TRAF2, by inducing TNF and TNF Receptor 2 (TNFR2) signaling. Genetically, we define that myeloid-specific cIAP1 loss promotes TLR-induced RIPK3-caspase-8 and IL-1β activity in the absence of XIAP...

REVIEW
Elizabeth A Thompson, Karin Loré
While transgenic mouse models are powerful for understanding how the immune system is manipulated by vaccines, they cannot fully recapitulate the characteristics of the innate immune responses leading to adaptive immunity after vaccination in humans. Outbred non-human primates are far more representative models of human vaccine responses as there is high degree of similarities in immune cell subset distributions, receptor expression (including toll-like receptors; TLRs), and immune cell functions, in addition to modeling doses and injection sites more accurately...

BACKGROUND: Patients with diabetes mellitus (DM) remain at higher risk of restenosis after percutaneous coronary intervention despite the use of contemporary drug-eluting stents. The Cre8 amphilimus-eluting stent (AES) has shown promising results in DM patients. Whether this holds true irrespective of patient's clinical and angiographic complexity is unknown. METHODS: Five hundred and ninety five consecutive patients (738 lesions) undergoing AES implantation were included in the INVESTIG8 multicenter registry...

Macrophage-related inflammatory response is one of the main biological factors resulting in failure of anterior cruciate ligament (ACL) reconstruction, although the specific pathomechanism remains to be clarified. Our aim was to investigate the association between graft loosening and macrophage-related inflammation in cases of loosening of reconstructed ACL autografts. Tissue samples were obtained from 21 patients who underwent a second-look arthroscopy within the first year after arthroscopic ACL reconstruction using single-bundle hamstring tendon autografts...

Toll-like receptors (TLRs) have been widely investigated due to their importance in the inflammatory response and possible links to tumor promotion/regression and prognosis. In cancers with an infective etiology, such as human papillomavirus (HPV)-associated Oropharyngeal Squamous Cell Carcinoma (OPSCC), TLR responses may be activated and play a role in tumorigenesis. Our aim was to assess the expression of all TLRs in OPSCC cell lines (both HPV+ and HPV-) by qPCR, Western Blot and flow cytometry and assess their response to TLR ligands lipopolysaccharide (LPS), LPS ultra-pure (LPS-UP) and peptidoglycan (PGN) by analyzing IL-8 and IL-6 production...

It has been reported previously that bovine miR-146a (bta-miR-146a) is significantly differentially expressed in mammary glands infected with mastitis, compared with healthy udders. This suggests that bta-miR-146a plays an important role in the regulation of mammary inflammation. However, the specifics of this function have yet to be elucidated. Bovine mammary epithelial cells (bMEC) represent the first line of defense against pathogens and have important roles in initiating and regulating inflammatory responses and innate immunity during infection...

The aim of the present study was to evaluate the long-term outcomes at 2 years in patients in whom everolimus-eluting stents (EESs) were implanted in small and non-small vessels. A small vessel is an important risk factor for restenosis with BMSs, even in the first generation DESs. The 690 patients with 690 lesions implanted with an EES were enrolled and divided into two groups by vessel reference diameter (RD): >2.5 mm for non-small vessels (Non-S-group) and ≤2.5 mm for small vessels (S-group). Two years later, the 365 patients with no restenosis at 8 months who underwent angiography were enrolled into the late catch-up study...

The role of phytochemicals in general well-being has been recognized. Curcumin is an ideal example. Hypoxia in adipose tissue is a major cause of inflammation and insulin resistance in obesity. Herein we mainly explored inflammation, insulin resistance and angiogenesis in 3T3-L1 adipocytes and possible reversal with the curcumin during hypoxia. Hypoxia for 24h significantly increased (P ≤ 0.05) the secretion of monocyte chemotactic protein-1 (4.59 fold), leptin (2.96 fold) and reduced adiponectin (2.93 fold)...

Respiratory Syncycial Virus (RSV) is the most important pathogen responsible for children's severe lower respiratory tract infection. So far no RSV vaccine has yet been authorized for clinical use. The main impediment that blocked development of RSV vaccine is that inactivated RSV vaccine could cause RSV vaccine-enhanced disease (RVED). The mechanism of RVED remains unclear. Recently some researchers found that insufficient activation of innate immunity, including Toll-like receptors (TLRs), might be associated with the onset of RVED...

Sepsis is a life-threatening health condition that is initially characterized by uncontrolled inflammation, followed by the development of persistent immunosuppression. YCP is a novel α-glucan purified from the mycelium of the marine fungus Phoma herbarum YS4108, which has displayed strong antitumor activity via enhancing host immune responses. In this study, we investigated whether YCP could influence the development of sepsis in a mouse model. Caecal ligation and puncture (CLP)-induced sepsis was established in mice that were treated with YCP (20 mg/kg, ip or iv) 2 h before, 4 and 24 h after the CLP procedure, and then every other day...

BACKGROUND: Diabetic kidney disease (DKD) is one of the most debilitating complications of type 2 diabetes. Recent evidence suggests chronic inflammation to be one of the causal factors of DKD. The mechanisms entailed are not completely elucidated except that a variety of cytokines play a major role in this process. High mobility group box 1 (HMGB1) is a pro-inflammatory toll-like receptor-4 (TLR4)-binding cytokine that is involved in inflammation-associated gene expression. This investigation was designed to assess the involvement of HMGB1, TLR-4, and nuclear factor (NF)-κB in the development of DKD and to evaluate that whether blocking HMGB1 by its natural inhibitor Glycyrrhizin (GLC) can reduce the progression of the disease...

One of the next challenges in cancer immunotherapy is the resistance of tumors to T cell-based treatments through loss of MHC class I. Here, we show that under these circumstances, the Toll-like receptor (TLR)-7/8 ligand imiquimod, but not the TLR3 ligand poly I:C or TLR9 ligand CpG, mediated an effective antitumor response. The rejection of these immune-escaped cancers was mediated by NK cells and CD4(+) T cells, whereas activated CD8(+) T cells were dispensable. Application of the innate immune stimulator at a distant site activated NK cells and thereby elicited tumor-specific T-cell responses in tumor-bearing mice...
