Major depressive disorder (MDD) is a chronic mental disease that adversely affects human mood and cognition. Many first-line antidepressant drugs have high rates of partial responsiveness or nonresponsiveness with side effects, and finding more effective drugs for the treatment of depression is therefore urgently needed. THSG, a main active compound of the traditional Chinese herb Polygonum multiflorum, reportedly acts as a neuroprotective agent. This study aimed to illustrate whether THSG prevents depressive-like behaviors induced by chronic restraint stress (CRS) in an MDD mouse model. Our results demonstrated that the peripheral administration of different THSG doses (10 mg/kg, 20 mg/kg, and 40 mg/kg) reversed the depressive-like behaviors in CRS mice as measured by the tail suspension test, forced swimming test, and open-field test. Further analyses suggested that THSG treatment reduced oxidative stress in both the central and peripheral nervous systems of CRS mice. In addition, heightened inflammatory responses, demonstrated by the increased expression of proinflammatory factors (TNF-α, IL-1β, and IL-6), in hippocampal and prefrontal cortex tissues of CRS mice were inhibited by THSG administration. THSG also restored the diminished Akt signaling pathway in the brains of CRS mice. Moreover, our data suggest increased astrocyte proliferation and neurogenesis in the hippocampus of CRS mice after THSG treatment. Taken together, our results demonstrated an antidepressant effect of THSG in a mouse model of MDD for the first time, and oxidative stress and inflammatory pathways were determined to play roles in this effect.

Depression is a mental disease that causes severe economic and social burdens. The mechanism for the onset of depression remains largely unknown. Recently, more and more attention is being given to the role of neuroinflammation and oxidative stress in depression. Tauroursodeoxycholic acid (TUDCA), a clinically available agent used to treat cholesterol gallstone and protect neurons against neurodegeneration, has been reported to prevent neuroinflammation and oxidative stress. In this study, we investigated the effect of TUDCA on lipopolysaccharide (LPS)-induced depression-like behavior, neuroinflammation, and oxido-nitrosative stress in mice. Results showed that TUDCA pretreatment (once daily for 7 consecutive days) at the dosage of 200 and 400 mg/kg, but not 100 mg/kg, markedly attenuated LPS (0.83 mg/kg)-induced behavioral abnormalities in the tail suspension test, forced swim test, and sucrose preference test. Further analysis showed that the TUDCA pretreatment (200, 400 mg/kg) not only inhibited the production of proinflammatory cytokines induced by LPS stimulation, such as interleukin-6 and tumor necrosis factor-α, but attenuated LPS-triggered oxido-nitrosative stress in the hippocampus and prefrontal cortex. Taken together, our results provide evidence to show that the TUDCA could be a potential antidepressant, and its antidepressive mechanism may be associated with the inhibition of the neuroinflammatory response and oxido-nitrosative stress in the brain.

Treatment Of Depression

Depression is a common mental disease, and it is one of the most crippling diseases in the world. Although current pharmacotherapies contribute to the treatment of depression, the high incidence of a partial responses or no responses, and delayed onset of the antidepressants, make many patients to experience unsatisfactory results from treatment. In view of the high suicide rate during the period of drug onset, it is critical to find antidepressant drugs with rapid onset for the treatment of depression. This paper mainly reviews some drugs that have rapid antidepressant effect and their mechanisms, including monoaminergic receptor drugs, glutamate receptor drugs, mammalian target of rapamycin (mTOR) signaling agonist, gamma-aminobutyric acid energy (GABAergic) agonist and drug combinations. In addition, we introduce several rodent models currently used to assess antidepressant onset in this review: chronic unpredictable mild stress (CUMS), forced swimming test (FST) and tail suspension test (TST), olfactory bulbectomy (OBX) and other models, which provide a methodological approach for assessing the rapid onset of antidepressant drugs.

Fucoxanthin is isolated from brown algae and was previously reported to have multiple pharmacological effects, including anti-tumor and anti-obesity effects in mice. Fucoxanthin also decreases the levels of inflammatory cytokines in the bronchoalveolar lavage fluid (BALF) of asthmatic mice. The purpose of the present study was to investigate the effects of fucoxanthin on the oxidative and inflammatory responses in inflammatory human tracheal epithelial BEAS-2B cells and attenuated airway hyperresponsiveness (AHR), airway inflammation, and oxidative stress in asthmatic mice. Fucoxanthin significantly decreased monocyte cell adherence to BEAS-2B cells. In addition, fucoxanthin inhibited the production of pro-inflammatory cytokines, eotaxin, and reactive oxygen species in BEAS-2B cells. Ovalbumin (OVA)-sensitized mice were treated by intraperitoneal injections of fucoxanthin (10 mg/kg or 30 mg/kg), which significantly alleviated AHR, goblet cell hyperplasia and eosinophil infiltration in the lungs, and decreased Th2 cytokine production in the BALF. Furthermore, fucoxanthin significantly increased glutathione and superoxide dismutase levels and reduced malondialdehyde (MDA) levels in the lungs of asthmatic mice. These data demonstrate that fucoxanthin attenuates inflammation and oxidative stress in inflammatory tracheal epithelial cells and improves the pathological changes related to asthma in mice. Thus, fucoxanthin has therapeutic potential for improving asthma.

Coptisine is the major bioactive protoberberine alkaloid found in Rhizoma Coptidis. Coptisine reduces inflammatory responses and improves glucose tolerance; nevertheless, whether coptisine has vasoprotective effect in diabetes is not fully characterized. Conduit arteries including aortas and carotid arteries were obtained from male C57BL/6J mice for ex vivo treatment with risk factors (high glucose or tunicamycin) and coptisine. Some arterial rings were obtained from diabetic mice, which were induced by high-fat diet (45% kcal% fat) feeding for 6 weeks combined with a low-dose intraperitoneal injection of streptozotocin (120 mg/kg). Functional studies showed that coptisine protected endothelium-dependent relaxation in aortas against risk factors and from diabetic mice. Coptisine increased phosphorylations of AMPK and eNOS and downregulated the endoplasmic reticulum (ER) stress markers as determined by Western blotting. Coptisine elevates NO bioavailability and decreases reactive oxygen species level. The results indicate that coptisine improves vascular function in diabetes through suppression of ER stress and oxidative stress, implying the therapeutic potential of coptisine to treat diabetic vasculopathy.

We have investigated the effect of daphnetin on depressive-like behavior and oxidative stress caused by corticosterone in mice. To this end, we have analyzed the effect of corticosterone alone and combination of corticosterone and daphnetin on three behavioral indices of depressive-like behavior - sucrose consumption rate, forced swimming test, and tail suspension test as well as biochemical markers of oxidative stress - malondialdehyde, nitrite, protein carbonyl, nonprotein sulfhydryl and glutathione contents as well as hippocampal cell apoptosis. The results support the conclusion that daphnetin diminished corticosterone induced depressive like behavior and oxidative stress by activating Nrf2/HO-1 pathway.

Hyperuricemia, which contributes to vascular endothelial damage, plays a key role in multiple cardiovascular diseases. This study was designed to investigate whether C1q/tumor necrosis factor (TNF)-related protein 3 (CTRP3) has a protective effect on endothelial damage induced by uric acid and its underlying mechanisms. Animal models of hyperuricemia were established in Sprague-Dawley (SD) rats through the consumption of 10% fructose water for 12 weeks. Then, the rats were given a single injection of Ad-CTRP3 or Ad-GFP. The animal experiments were ended two weeks later. In vitro, human umbilical vein endothelial cells (HUVECs) were first infected with Ad-CTRP3 or Ad-GFP. Then, the cells were stimulated with 10 mg/dL uric acid for 48 h after pretreatment with or without a Toll-like receptor 4 (TLR4)-specific inhibitor. Hyperuricemic rats showed disorganized intimal structures, increased endothelial apoptosis rates, increased inflammatory responses and oxidative stress, which were accompanied by reduced CTRP3 and elevated TLR4 protein levels in the thoracic aorta. In contrast, CTRP3 overexpression decreased TLR4 protein levels and ameliorated inflammatory responses and oxidative stress, thereby improving the morphology and apoptosis of the aortic endothelium in rats with hyperuricemia. Similarly, CTRP3 overexpression decreased TLR4-mediated inflammation, reduced oxidative stress, and rescued endothelial damage induced by uric acid in HUVECs. In conclusion, CTRP3 ameliorates uric acid-induced inflammation and oxidative stress, which in turn protects against endothelial injury, possibly by inhibiting TLR4-mediated inflammation and downregulating oxidative stress.

Background/Aims: Inflammation and oxidative stress play an important role in myocardial ischemia and reperfusion (I/R) injury. We hypothesized that IL-23, a pro-inflammatory cytokine, could promote myocardial I/R injury by increasing the inflammatory response and oxidative stress. Methods: Male Sprague-Dawley rats were randomly assigned into sham operated control (SO) group, ischemia and reperfusion (I/R) group, (IL-23 + I/R) group and (anti-IL-23 + I/R) group. At 4 h after reperfusion, the serum concentration of lactate dehydrogenase (LDH), creatine kinase (CK) and the tissue MDA concentration and SOD activity were measured. The infarcte size was measured by TTC staining. Apoptosis in heart sections were measured by TUNEL staining. The expression of HMGB1 and IL-17A were detected by Western Blotting and the expression of TNF-α and IL-6 were detected by Elisa. Results: After 4 h reperfusion, compared with the I/R group, IL-23 significantly increased the infarct size, the apoptosis of cardiomyocytes and the levels of LDH and CK (all P < 0.05). Meanwhile, IL-23 significantly increased the expression of eIL-17A, TNF-α and IL-6 and enhanced both the increase of the MDA level and the decrease of the SOD level induced by I/R (all P<0.05). IL-23 had no effect on the expression of HMGB1 (p > 0.05). All these effects were abolished by anti-IL-23 administration. Conclusion: The present study suggested that IL-23 may promote myocardial I/R injury by increasing the inflammatory responses and oxidative stress reaction.

The efficacy of stem cells for the treatment of renal failure is widely recognized; however, an excessive volume of stem cells can block the capillaries; thus, the potential risks should not be ignored. Stem cell exosomes are secretory extracellular vesicles with a size of 30–150 nm, which have similar functions to stem cells but are much smaller in size. This study aims to investigate the role of human umbilical cord mesenchymal stem cells (UCMSCs)-derived exosomes in the treatment of renal failure caused by ischemia-reperfusion. Fifty 8-week-old female C57 mice underwent bilateral renal ischemia-reperfusion surgery for 30 minutes. After 4 weeks, the treated group received UCMSCs-derived exosomes treatment, and the control group was solely injected with the same amount of PBS. At the age of 16 weeks, the kidney function, kidney damage, inflammatory responses and oxidative stress were measured. Moreover, the effect of UCMSCs-derived exosomes on the phenotype of M1 macrophages was also tested. The results showed that UCMSCsderived exosomes significantly reduced the levels of blood urea nitrogen (BUN), serum creatinine (SCR), and urinary albumin and creatinine (ACR) and 8-isoprostane. UCMSCs-derived exosomes also improved the atrophy of the kidney and glomerulus, decreased kidney pro-inflammatory factors expression (mRNA of II-1β, II-6, Tnf-α, and Mcp-1) and oxidative stress (malondialdehyde), and increased glutathione level. However, F4/80 immunohistochemistry did not show significant differences between the two groups. In systemic inflammation measurement, UCMSCs-derived exosomes decreased proinflammatory factors TNF-α, IL-6, and IL-1β levels, and increased anti-inflammatory factor IL-10 level. In vitro experiments showed that UCMSCs-derived exosomes decreased the protein expression level of TNF-α and increased the protein expression level of IL-10 in M1 macrophages. UCMSCs-derived exosomes reduce kidney inflammation and oxidative stress by improving systemic inflammation, and thus reduce kidney damage and improve kidney function. This study shows the potential application value of exosomes in the treatment of renal failure.
