High-Tech Methods of Cytokine Imbalance Correction in Intervertebral Disc Degeneration. Int J Mol Sci 2023; 24:13333. [PMID: 37686139 PMCID: PMC10487844 DOI: 10.3390/ijms241713333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 08/24/2023] [Accepted: 08/25/2023] [Indexed: 09/10/2023] Open
Abstract
An important mechanism for the development of intervertebral disc degeneration (IDD) is an imbalance between anti-inflammatory and pro-inflammatory cytokines. Therapeutic and non-therapeutic approaches for cytokine imbalance correction in IDD either do not give the expected result, or give a short period of time. This explains the relevance of high-tech medical care, which is part of specialized care and includes the use of new resource-intensive methods of treatment with proven effectiveness. The aim of the review is to update knowledge about new high-tech methods based on cytokine imbalance correction in IDD. It demonstrates promise of new approaches to IDD management in patients resistant to previously used therapies, including: cell therapy (stem cell implantation, implantation of autologous cultured cells, and tissue engineering); genetic technologies (gene modifications, microRNA, and molecular inducers of IDD); technologies for influencing the inflammatory cascade in intervertebral discs mediated by abnormal activation of inflammasomes; senolytics; exosomal therapy; and other factors (hypoxia-induced factors; lysyl oxidase; corticostatin; etc.).

Abstract
Purpose To evaluate serum cortistatin (CST) levels in type 2 diabetes mellitus (T2DM) patients with or without non-alcoholic fatty liver disease (NAFLD) and to examine the relationship between CST and NAFLD. Methods A total of 90 T2DM patients, which included 56 NAFLD patients (referred to as DM+NAFLD group) and 34 patients without NAFLD (DM-only group), and 83 non-diabetes individuals that included 39 NAFLD patients (NAFLD-only group) and 44 without NAFLD that acted as the normal-control group (NC group). The differences in the serum CST levels between the groups were compared, and the correlations between CST and other variables were calculated by applying both correlational analysis and multiple linear regression analysis. Results The mean serum CST levels were significantly lower in the DM+NAFLD and DM groups than in the NC group (P < 0.05). In addition, the CST levels were lower in the DM group relative to that in the NAFLD group (P < 0.05). However, no statistical difference was noted in the serum CST between diabetic patients with and without NAFLD (P > 0.05). Similarly, in the non-diabetic group, the serum CST level was not significantly different between individuals with and without NAFLD (P > 0.05). Furthermore, the serum CST levels were negatively associated with the levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), fasting plasma glucose (FPG), homeostasis model assessment-insulin resistance (HOMA-IR), and insulin cell function index (HOMA-β). Conversely, the serum CST levels were positively associated with high-density lipoprotein cholesterol (HDL-C). The data obtained through multiple linear regression implied that LDL-C and HOMA-β, but not HOMA-IR, were closely related to serum CST levels. Conclusion T2DM was related to decreased serum CST. However, serum CST was correlated with HOMA-β in T2DM patients, while HOMA-IR was not. There was no correlation between CST and NAFLD.

Abstract
Rheumatoid arthritis has a significant impact on the life quality, but current pharmacological therapies have limitations. As a result, there is growing interest in exploring the potential of natural plant components to intervene in the development of rheumatoid arthritis. Resveratrol, a natural polyphenol and one of the main active components of the Chinese herbal medicine Polygonum cuspidatum, has emerged as a promising candidate for this purpose. In the present study, we investigated the role and mechanism of resveratrol in inhibiting inflammatory response in rat primary fibroblast-like synoviocytes. Tumor necrosis factor (TNF)-α was used to establish a model of inflammation, the Sirtuin1 selective inhibitor Selisistat (EX527) was used to inhibit Sirtuin1 activity, and small interfering RNA was used to silence cortistatin expression. The results showed that pre-treatment with resveratrol could time- and dose-dependently inhibit TNF-α induced cellular interleukin (IL)-1β and IL-6 secretion, and upregulate Sirtuin1 and cortistatin mRNA and protein expression in the range of 48 h, 100 µM. Selisistat (EX527) could attenuate resveratrol inhibited inflammatory response and upregulated cortistatin expression. Silencing cortistatin expression attenuated the effect of resveratrol on inhibiting inflammatory response, but did not affect its effect on upregulating Sirtuin1 expression. In conclusion, resveratrol effectively inhibited the TNF-α induced inflammatory response in fibroblast-like synoviocytes by a mechanism involving the Sirtuin1/cortistatin pathway.

Abstract
Background: Intervertebral disc (IVD) degeneration is a common degenerative disease that can lead to collapse or herniation of the nucleus pulposus (NP) and result in radiculopathy in patients. Methods: NP tissue and cells were isolated from patients and mice, and the expression profile of cortistatin (CST) was analysed. In addition, ageing of the NP was compared between 6-month-old WT and CST-knockout (CST-/-) mice. Furthermore, NP tissues and cells were cultured to validate the role of CST in TNF-α-induced IVD degeneration. Moreover, in vitro and in vivo experiments were performed to identify the potential role of CST in mitochondrial dysfunction, mitochondrial ROS generation and activation of the NLRP3 inflammasome during IVD degeneration. In addition, NF-κB signalling pathway activity was tested in NP tissues and cells from CST-/- mice. Results: The expression of CST in NP cells was diminished in the ageing- and TNF-α-induced IVD degeneration process. In addition, compared with WT mice, aged CST-/- mice displayed accelerated metabolic imbalance and enhanced apoptosis, and these mice showed a disorganized NP tissue structure. Moreover, TNF-α-mediated catabolism and apoptosis were alleviated by exogenous CST treatment. Furthermore, CST inhibited mitochondrial dysfunction in NP cells through IVD degeneration and suppressed activation of the NLRP3 inflammasome. In vitro and ex vivo experiments indicated that increased NF-κB pathway activity might have been associated with the IVD degeneration observed in CST-/- mice. Conclusion: This study suggests the role of CST in mitochondrial ROS and activation of the NLRP3 inflammasome in IVD degeneration, which might shed light on therapeutic targets for IVD degeneration.

Abstract
PURPOSE To evaluate the aqueous humor and serum cortistatin levels in diabetic patients with and without diabetic retinopathy and its relationship with various metabolic markers that have been reported to be associated with diabetes mellitus. METHODS The current study included 20 diabetes mellitus patients with diabetic retinopathy, 20 diabetes mellitus patients without diabetic retinopathy, and 20 healthy control subjects with the same sex and age characteristics. Aqueous humor and serum cortistatin, fasting blood glucose, hemoglobinA1c, 25-hydroxyvitamin D levels, blood lipid profiles, and body mass index were measured in all subjects. RESULTS In diabetic patients with and without diabetic retinopathy and in healthy control subjects, the mean aqueous humor cortistatin levels were 25.55 ± 2.03, 27.71 ± 2.01, and 32.76 ± 3.43 ng/mL, respectively. Likewise, the mean serum cortistatin levels were 6.16 ± 1.08, 6.57 ± 1.00, and 7.56 ± 1.51 ng/mL, respectively. Aqueous humor cortistatin levels were decreased in diabetic patients with and without diabetic retinopathy when compared to healthy controls (p < 0.001). Although aqueous humor cortistatin levels tended to be reduced in diabetic patients with diabetic retinopathy, the difference was not statistically significant between diabetic patients with and without diabetic retinopathy (p = 0.147). Serum cortistatin levels were not statistically significant between diabetic patients with and without diabetic retinopathy and healthy control subjects (p = 0.166). Body mass index, fasting blood glucose, and hemoglobinA1c levels were significantly different between the groups (p < 0.05 for all parameters tested). CONCLUSION Aqueous humor cortistatin levels were decreased in diabetic patients with and without diabetic retinopathy. The results suggest that a local decrease in the amount of cortistatin may play a role in the pathogenesis of diabetic retinopathy.

Abstract
Objective: To investigate serum cortistatin levels in women with gestational diabetes mellitus (GDM) and women with uncomplicated pregnancies.Material and methods: This case-control study consisted of 40 pregnancies with GDM and 41 healthy singleton pregnancies matched for maternal and gestational age. The maternal serum levels of cortistatin were measured with enzyme-linked immunosorbent assay and compared between groups.Results: Cortistatin levels were significantly lower in GDM group (48.85 ± 20.18 versus 65.84 ± 33.98 ng/ml, p = .008). There was a statistically significant difference in cortistatin levels between different treatment modalities and control group (χ2(2) = 8.828, p = .012). Pairwise comparisons showed that diet group had significantly lower CST levels than control group (p = .012). Serum cortistatin levels were negatively correlated with serum insulin and glucose levels and HOMA-IR (r = -0.358, p = .001; r = -0.303, p = .006; r = -0.444, p < .001, respectively).Conclusion: Cortistatin levels were significantly lower in GDM pregnancies and related to serum insulin and glucose levels and HOMA-IR in pregnancy. This may help to better clarify the mechanism of GDM pathogenesis.

Abstract
Cortistatin-14 (CST-14), a recently discovered cyclic neuropeptide, can bind to all five cloned somatostatin receptors (SSTRs) and ghrelin receptor to exert its biological activities and co-exists with GABA within the cortex and hippocampus. However, the role of CST-14 in the control of depression processes is not still clarified. Here, we tested the behavioral effects of CST-14 in the in a variety of classical rodent models of depression [forced swimming test (FST), tail suspension test (TST) and novelty-suppressed feeding test]. In the models of depression, CST-14 produced antidepressant-like effects, and does not altered locomotor activity levels. And, we found that CST-14 mRNA and BDNF mRNA were significantly decreased in the hippocampus and cortex after mice exposed to stress. Further data show that i.c.v. administration of CST-14 produce rapid antidepressant effects, and does not altered locomotor activity levels. Then these antidepressant-like effects were significantly reversed by [D-Lys3]GHRP-6 (ghrelin receptor antagonist), but not c-SOM (SSTRs antagonist). Meanwhile, the effects of some neurotransmitter blockers indicates that only GABAA system, but not CRF1 receptor, α/β-adrenergic receptor, is involved in the antidepressant effect of CST-14. The effects of the mTOR inhibitor (rapamycin), the PI3K inhibitor (LY294002) and the p-ERK1/2 inhibitor (U0126) suggesting that the ERK/mTOR or PI3K/Akt/mTOR signaling pathway is not involved in the antidepressant effects of CST-14. Interestingly, intranasal administration of CST-14 led to reducing depressive-like behavior, and near-infrared fluorescent experiments showed the real-time in vivo bio-distribution in brain after intranasal infusion of Cy7.5-CST-14. Taken all together, the results of present study point to a role for CST-14 in the modulation of depression processes via the ghrelin and GABAA receptor, and suggest cortistation may represent a novel strategy for the treatment of depression disorders. Highlights:CST-14 and BDNF mRNA are decreased in hippocampus and cortex once mice exposed to stress. i.c.v. or intranasal administration of CST-14 produce rapid antidepressant effects. NIR fluorescence imaging detected the brain uptake and distribution after intranasal CST-14. Antidepressant effects of CST-14 were only related to ghrelin and GABAA system. Co-injection of CST-14 and NPS produce antidepressant effect, and do not impair memory.

Abstract
Cortistatin (CST) is a recently discovered cyclic neuropeptide with multiple bioactive effects. The aim of this study was to investigate the relationship between plasma CST and various metabolic markers in patients with newly diagnosed type 2 diabetes mellitus (T2DM). For this study, 60 patients with newly diagnosed T2DM and 38 age- and gender-matched healthy controls were recruited. Fasting plasma glucose (FPG), serum insulin and hemoglobin A1c (HbA1c) levels and a blood lipid profile were obtained with commercially available diagnostic reagents. CST plasma levels were determined using an enzyme immunoassay kit. The results showed that the plasma levels of CST were substantially lower in patients with newly diagnosed T2DM compared with the healthy controls. Plasma CST levels were positively correlated with high-density lipoprotein and negatively related to FPG, serum insulin, the homeostasis model assessment of insulin resistance (HOMA-IR) and HbA1c in all subjects. Further analysis showed that CST levels were positively correlated with systolic blood pressure and negatively correlated with FPG, serum insulin, HOMA-IR and HbA1c in patients with newly diagnosed T2DM. Moreover, logistic regression analyses indicated that plasma CST was correlated with newly diagnosed T2DM. In conclusion, patients with newly diagnosed T2DM had significantly lower plasma levels of CST than healthy controls, and plasma CST was associated with glucose metabolism and insulin resistance, indicating a potential role of CST in the development of T2DM.

Abstract
Cortistatin is a neuropeptide isolated from cortical brain regions, showing high structural homology and sharing many functions with somatostatin. However, cortistatin exerts unique functions in the central nervous and immune systems, including decreasing locomotor activity, inducing sleep-promoting effects, and deactivating inflammatory and T helper (TH )1/TH 17-driven responses in preclinical models of sepsis, arthritis, multiple sclerosis, and colitis. Besides its release by cortical and hippocampal interneurons, cortistatin is produced by macrophages, lymphocytes, and peripheral nociceptive neurons in response to inflammatory stimuli, supporting a physiological role of cortistatin in the immune and nociceptive systems. Cortistatin-deficient mice have been shown to have exacerbated nociceptive responses to neuropathic and inflammatory pain sensitization. However, a paradoxical effect has been observed in studies of immune disorders, in which, despite showing competent inflammatory/autoreactive responses, cortistatin-deficient mice were partially resistant to systemic autoimmunity and inflammation. This unexpected phenotype was associated with elevated circulating glucocorticoids and anxiety-like behavior. These findings support cortistatin as a novel multimodal therapeutic approach to treat autoimmunity and clinical pain and identify it as a key endogenous component of the neuroimmune system related to stress responses.
