Boost K, Hoegl S, Hofstetter C, Flondor M, Stegewerth K, Platacis I, Pfeilschifter J, et al. The present review will describe the structure and mechanisms of activation of the NLRP3 inflammasome, its association with various auto-immune and auto-inflammatory diseases, and the state of research into NLRP3 inflammasome inhibitors. Structure of the absent in melanoma 2 (AIM2) pyrin domain provides insights into the mechanisms of AIM2 autoinhibition and inflammasome assembly. Therefore, the therapeutic approach of combining TNF-α expression-reducing substances with pralnacasan appears to be a promising idea [131]. Interleukin-1β (IL-1β), a product of the NLRP3 inflammasome, modulates cardiac contractility and diastolic function. 2018;22(11):5670–81. Studies have found that the activation of the obesity-associated NLRC4 inflammasome drives breast cancer progression [47]. Caspases are a family of cysteine proteases that play an important role in anti-microbial immune responses and inflammatory disorders. Caspase-1 inhibition alleviates cognitive impairment and neuropathology in an Alzheimer’s disease mouse model. Mol Med Rep. 2015;11(2):1139–45. The inflammasome is activated by the recognition of P2X7R, leading to the cleavage of caspase-1. Consequently, the application of inflammasome inhibitors must be tailored to the specific type of cancer, and further studies are warranted to characterize the antitumor effects of these drugs. The tight regulation of these immune sensors is necessary to control an optimal inflammatory response and recover organism homeostasis. Mol Cancer Ther. Several of the inflammasome inhibitors detailed above have been demonstrated to have the function of reducing inflammatory responses, indicating that inflammasome inhibitors could be novel candidates for the treatment of malignancies in which inflammation is involved as a major contributor. The development of NLRP3 inflammasome inhibitors has opened the possibility to targeting the deleterious effects of NLRP3.

IL-1 beta-converting enzyme is present in monocytic cells as an inactive 45-kDa precursor. The tight regulation of these immune sensors is necessary to control an optimal inflammatory response and recover organism homeostasis. Both the priming and the activation of the inflammasome are regulated by a deubiquitination mechanism. The administration of parthenolide can activate p53, leading to a reduction in cancer cell proliferation [103]. Inflammasomes are part of the innate immune system, triggering an inflammatory response by activating caspases. Interact with the different pathway diagrams with our kits numbers wherever applicable. However, emerging evidence indicates that inflammation triggered by viral or microbial infection plays a crucial role in tumorigenesis [3]. 13 HSP90 is suggested to bind NLRP3 . 2007;67(20):10019–26. Invest New Drugs. In unresectable hepatocellular carcinoma, thalidomide is tolerated in most patients with gradual dose escalation, but its monotherapeutic activity is modest compared with that of the combined therapy [84].

Glyburide is anti-inflammatory and associated with reduced mortality in melioidosis. Rothwell PM, Fowkes FG, Belch JF, Ogawa H, Warlow CP, Meade TW. High expression of P2X7R is an independent postoperative indicator of poor prognosis in colorectal cancer. NLRP3 Inflammasome Inhibitor I, an intermediate substrate in the synthesis of glyburide which is free of the cyclohexylurea moiety involved in insulin release, is a novel inhibitor of the NLRP3 inflammasome. As excessive inflammation induced by the inflammasome can be a detrimental factor in multiple types of cancer, inflammasome inhibitors appear to be a promising approach for cancer prevention and treatment. 4, Marco C Inserra.

Audia JP, Yang XM, Crockett ES, Housley N, Haq EU, O'Donnell K, et al. There are several recent in-depth reviews on NLRP3 inflammasome inhibitors.

Inhibition of cell-cycle progression in human colorectal carcinoma Lovo cells by andrographolide. J Clin Oncol. After the recognition of activating signals such as ATP or LPS, mitochondrial DNA is released into the cytosol and then bound directly by the NLRP3 inflammasome, leading to the activation of the inflammasome and maturation of caspase-1 [28].
