- |||||||||| Review, Journal: Hidden Aspects of Valency in Immune System Regulation. (Pubmed Central) - Jul 25, 2020
We discuss some of the ways in which valency itself is regulated through transcriptional, post-transcriptional, and post-translational modifications. Finally, we propose that the valency model can be applied at the whole cell level to study differences in individual cell responses with relevance to putative therapeutic applications.

Our findings indicate that oncogenic KRAS not only act via its canonical oncogenic driver function, but also enhances the activation of the pro-inflammatory RAC1/ROS/NLRP3/IL-1β axis. This paves the way for a therapeutic approach based on immune modulation via NLRP3 blockade in KRAS-mutant myeloid malignancies.
- |||||||||| Review, Journal: Pro-inflammatory Actions of Heme and Other Hemoglobin-Derived DAMPs. (Pubmed Central) - Jul 24, 2020
The contribution of oxidized Hb forms is much less studied, but some evidence show that these species might play distinct roles in intravascular hemolysis-associated pathologies independently of heme release. This review aims to summarize our current knowledge about the formation and pro-inflammatory actions of heme and other Hb-derived DAMPs.
- |||||||||| Journal: Adiponectin alleviates NLRP3-inflammasome-mediated pyroptosis of aortic endothelial cells by inhibiting FoxO4 in arteriosclerosis. (Pubmed Central) - Jul 21, 2020
Specifically, APN reduced propidium-iodide-positive cells, NLRP3 inflammasomes, apoptosis-related speck-like protein containing caspase recruitment domains, and pro-inflammation factors IL-1β and IL-18, all of which was reversed by overexpression of FoxO4. In conclusion, our study suggests that APN might play an essential role in NLRP3 inflammasome-modulated pyroptosis by regulating FoxO4 in human aortic epithelial cells, providing a novel therapy for atherosclerosis.
- |||||||||| Review, Journal: Current status of terpenoids as inflammasome inhibitors. (Pubmed Central) - Jul 21, 2020
Thus, terpenoids represent an interesting pharmacological approach for the treatment of inflammatory diseases as they are endowed with a dual mechanism of inhibition of NF-KB transcription factor and inflammasome activation, both critically involved in their anti-inflammatory effects. This work provides an overview of the current knowledge on the therapeutic potential of terpenoids as NLRP3 inflammasome inhibitors.

Preclinical, Journal: Circadian Pharmacological Effects of Berberine on Chronic Colitis in Mice: Role of the Clock Component Rev-erbα. (Pubmed Central) - Jul 21, 2020 Chronic colitis was induced by feeding mice with dextran sulfate sodium in drinking water...In conclusion, circadian pharmacological effects of berberine on chronic colitis were mainly contributed by diurnal rhythms of both disease severity and Rev-erbα (as a drug target). The findings may have implications for chronotherapeutic practice on colitis or related diseases.

Journal, IO Biomarker: Dexmedetomidine reduces the inflammation and apoptosis of doxorubicin-induced myocardial cells. (Pubmed Central) - Jul 21, 2020 However, those above changes could be reversed by Compound C. In conclusion, this study indicated that DEX could reduce the inflammation and apoptosis of DOX-induced myocardial cells through activating the AMPK-GSK3β signaling pathway. Because of the above effects of DEX, it may be beneficial for surgical patients with heart problems.

The efficiency of Gsdmd cleavage by inflammatory caspase-1 was dramatically reduced when oxidative modification was blocked by mutation of these amino acid residues. These results demonstrate that Gsdmd oxidation serves as a de novo mechanism by which mitochondrial ROS promote Nlrp3 inflammasome-dependent pyroptotic cell death.

Preclinical, Journal: Effects of sDR5-Fc fusion protein on infant mice with ulcerative colitis via the TRAIL-DR5 pathway. (Pubmed Central) - Jul 19, 2020 To explore effects of the sDR5-Fc fusion protein on ulcerative colitis of infant mice via the TRAIL-DR5 pathway, 50 female mice were randomly divided into 5 groups, i.e., control group (group A), dextran sulfate sodium group (group B), hIgG group (group C), 10 mg/kg sDR5-Fc group (group D), and 20 mg/ kg sDR5-Fc group (group E)...Thus, sDR5-Fc could inhibit the activation of NLRP3 inflammasomes induced by TRAIL, thereby decreasing the apoptosis of NCM460 cells. In conclusion, the sDR5-Fc fusion protein could block the TRAIL-DR5 pathway to reduce the expression of NLRP3 inflammasomes, thereby improving ulcerative colitis.
- |||||||||| Journal: The NLRP3-Mediated Neuroinflammatory Responses to CdTe Quantum Dots and the Protection of ZnS Shell. (Pubmed Central) - Jul 19, 2020
Even though the milder immune responses and neurotoxicity of CdTe@ZnS QDs compared with CdTe QDs indicated the protective role of ZnS coating, the inhibitions of NLRP3 expression and ROS production completely reduced the IL-1ß-mediated inflammation. This provided valuable information that inhibiting target molecules is an effective and efficient way to alleviate the toxicity of cadmium-containing QDs, so it is important to evaluate QDs through a mechanism-based risk assessment.
