The cholinergic anti-inflammatory pathway is recognized as one of the main mechanisms of neuromodulation of the immune system. Activation of the α7 nicotinic acetylcholine receptor (nAchRα7) suppresses cytokine synthesis in distinct immune cells but the molecular mechanisms behind this effect remain to be fully described. Mast cells (MCs) are essential players of allergic reactions and innate immunity responses related to chronic inflammation. Activation of TLR4 receptor in MCs leads to the rapid secretion of pre-synthesized TNF from intracellular pools and to the activation of NFκB, necessary for de novo synthesis of TNF and other cytokines...

Targeting the TNFα pathway is a validated approach to the treatment of psoriasis. In this pathway, TACE stands out as a druggable target and has been the focus of in-house research programs. In this article, we present the discovery of clinical candidate 26a. Starting from hits plagued with poor solubility or genotoxicity, 26a was identified through thorough multiparameter optimisation. Showing robust in vivo activity in an oxazolone-mediated inflammation model, the compound was selected for development. Following a polymorph screen, the hydrochloride salt was selected and the synthesis was efficiently developed to yield the API in 47% overall yield...

BACKGROUND: Concurrent chemoradiation therapy (CCRT) followed by hepatic arterial infusional chemotherapy (HAIC) was reported to be effective for advanced hepatocellular carcinoma (HCC) with portal vein thrombosis. However, transarterial chemoembolization (TACE) is not preferred in this setting. The aim of this study was to assess the factors affecting survival after CCRT, including additional TACE during repeated HAIC. METHODS: Thirty-eight patients who underwent CCRT as the initial treatment for Barcelona Clinic Liver Cancer stage C HCC with vascular invasion between 2009 and 2016 were reviewed retrospectively...

BACKGROUND AND OBJECTIVES: Combination of transcatheter arterial chemoembolization (TACE) and radiofrequency ablation (RFA) has become an effective alternative therapy for hepatocellular carcinoma (HCC). In clinical practice, the choice of time interval between TACE and RFA is a key point for curative effect, but optimal time interval is uncertain in guidelines. We aim to explore the optimal time interval for HCC patients of Child-Pugh classification A or B. METHODS: Two hundred and thirty-three HCC patients of Child A or B who had undergone TACE and RFA were enrolled and divided into seven groups according to different time intervals (1-7weeks)...

The salvage liver transplantation (SLT) strategy was conceived for initially resectable and transplantable (R&T) hepatocellular carcinoma (HCC) patients, to try to obviate upfront LT, with the 'safety net' of SLT in case of post-resection recurrence. The SLT strategy is successful or curative when patients are recurrence-free following primary resection alone, or after SLT for recurrence. The aim of the current study was to determine the SLT strategy's potential for cure in R&T HCC patients, and to identify predictors for its success...

According to the current European Association for the Study of Liver guidelines, transarterial chemoembolization (TACE) is the recommended first-line therapy for patients with intermediate-stage (Barcelona Clinic Liver Cancer-B class) hepatocellular carcinoma (HCC). The efficacy of this therapy is supported by robust evidence; however, there is still a lack of standardization in treatment methodology, and TACE protocols are widely variable. Moreover, TACE can be associated with a number of contraindications...

Although cellular prion protein PrP(C) is well known for its implication in Transmissible Spongiform Encephalopathies, its functions remain elusive. Combining in vitro and in vivo approaches, we here show that PrP(C) displays the intrinsic capacity to protect neuronal cells from a pro-inflammatory TNFα noxious insult. Mechanistically, PrP(C) coupling to the NADPH oxidase-TACE α-secretase signaling pathway promotes TACE-mediated cleavage of transmembrane TNFα receptors (TNFRs) and the release of soluble TNFR, which limits the sensitivity of recipient cells to TNFα...

Patients with early-stage hepatocellular carcinoma (HCC) are potential candidates for curative treatments such as radiofrequency ablation (RFA), surgical resection (SR), or liver transplantation (LT), which have demonstrated a significant survival benefit. We aimed to estimate the cost-effectiveness of curative and combination treatment strategies among patients diagnosed with HCC during 2002-2010. This study used Ontario Cancer Registry-linked administrative data to estimate effectiveness and costs (2013 USD) of the treatment strategies from the healthcare payer's perspective...

Tumor necrosis factor (TNF)-α is a major pro-inflammatory cytokine produced in response to toll-like receptor stimulation. TNF-α release is controlled by the activity of TNF-α converting enzyme (TACE) that cut membrane-bound TNF-α to shed its ectodomain as a soluble cytokine. The purinergic receptor P2X ligand-gated ion channel 7 (P2X7) is activated in response to elevated concentrations of extracellular ATP and induces different pro-inflammatory pathways in macrophages to establish an inflammatory response...

Transarterial chemoembolization (TACE) is the standard treatment for intermediate stage, although the combination of TACE with sorafenib may theoretically benefit HCC patients in intermediate stage. Owing to the significant antiangiogenic effect of sorafenib and the limitation of TACE, it is rational to combine them. Though the strategy of combining TACE and sorafenib has been increasingly used in patients with unresectable HCC but the current evidence is controversial and its clinical role has not been determined yet...
