Pathophysiology and Treatment of Major Depressive Disorder: The Role of Nuclear Receptors Modulate Inflammasomes | Chapter 4 | Medicine and Medical Research: New Perspectives Vol. 7

 

This review summarizes the evidence on nuclear receptors (NRs), such as glucocorticoid receptor, mineralocorticoid receptor, estrogen receptor, aryl hydrocarbon receptor, and peroxisome proliferator-activated receptor, in modulating the inflammasome activity and depression-associated behaviors. Major depressive disorder (MDD) is highly prevalent and is a significant cause of mortality and morbidity worldwide. Currently, conventional pharmacological treatments for MDD produce temporary remission in < 50% of patients; therefore, there is an urgent need for a wider spectrum of novel antidepressants to target newly discovered underlying disease mechanisms. Another important hypothesis of depression, several lines of evidence have established an association between MDD and the neuroimmune pathway, although some psychiatrists have argued about the causal relationship between inflammation and depression. Accumulated evidence has shown that immune inflammation, particularly inflammasome activity, plays an important role in the pathophysiology of MDD. This review provides evidence from an endocrine perspective to understand the role of activated NRs in the pathophysiology of MDD and to provide insight into the discovery of antidepressants with novel mechanisms for this devastating disorder. Cumulative studies have shown that activation of the NRs may directly change the activity of inflammasomes to modulate the levels of mature forms of caspase-1 and IL-1

Mercury-based Traditional Medicines: Chemical Composition and Mineral-herb Mixtures Differ from Toxic Mercury Compounds on Hepatic Cytochrome P450| Chapter 5 | Recent Progress in Science and Technology Vol. 1

 Zuotai  (β-HgS)-holding 70 Wei-Zhen-Zhu-Wan (70W, Qishiwei, Rannasangpei) is a Chinese ethnomedicine at Qinghai-Tibet region for cardiovascular and gastrointestinal ailments.  We have found that 70W shielded against CCl4 hepatotoxicity. Utilizing cytochrome P450 (CYP), CCl4 is metabolized to create sensitive metabolites. It is unclear either 70W has any affect CYPs, and any specific impact should be distinguished to harmful planets orbiting sun compounds for safety evaluation.  In this experiment, Mice were given dispassionate doses of 70W (0.15-1.5 g/kg, po), Zuotai (30 mg/kg, po), and compared to HgCl2 (33.6 mg/kg, po) and MeHg (3.1 mg/kg, po) for 7 days. Liver RNA and protein were unique for qPCR and Western-blot analysis.The verdicts of this study granted that 70W and Zuotai had no belongings on hepatic mRNA expression of Cyp1a2, Cyp2b10, Cyp3a11, Cyp4a10 and Cyp7a1, and matching nuclear receptors [aryl hydrocarbon receptor (AhR), essential androstane receptor (CAR), pregnane X receptor (PXR), peroxisome proliferator-activated receptor-α (PPARα); farnesoid X receptor (FXR)]. In comparison, HgCl2 and MeHg raised mRNA expression of Cyp1a2, Cyp2b10, Cyp4a10 and Cyp7a1 except that Cyp3a11, and corresponding basic receptors except for PXR. Western-blot rooted mRNA results, showing increases in CYP1A2, CYP2B1, CYP2E1, CYP4A and CYP7A1 by HgCl2 and MeHg only, in addition treatments had no belongings on CYP3A.In contrast to HgCl2 and MeHg, Zuotai and Zuotai-containing 70W had little affect the hepatic CYPs and associated basic receptors. Thus, HgS-herb combinations differ from poisonous Hg compounds on hepatic P450 and nuclear receptors.
