Abstract
BACKGROUND AND AIM Nonalcoholic steatohepatitis (NASH) is a critical stage in the prognosis of nonalcoholic fatty liver disease (NAFLD). Pure total flavonoids from circus (PTFC) play essential roles in the improvement of NASH symptoms, but the underlying regulatory mechanism remains elusive. Our previous high-throughput omics screening results indicate that the CCL2/CCR2-PI3K-Akt signaling pathway is a key pathway that regulates the liver inflammatory response. PTFC may regulate the CCL2/CCR2-PI3K-Akt signaling pathway to improve the liver inflammatory response. METHODS A mice model of NASH was established by a high-fat diet, and PTFC was used as treatment. Hematoxylin-eosin and oil red O staining were used to observe the pathological changes in the liver tissue. Western blotting and real-time PCR were used to measure the mRNA and protein levels in the liver. The expression of proinflammatory cytokines in the peripheral blood and liver tissues was measured by liquid suspension array. An automatic biochemical method was used to examine serum transaminases and lipids levels, as well as liver lipids. RESULTS Compared with the mice in the high-fat diet group, mice in the HFD + PTFC group showed significantly improved liver histopathology, and levels of serum transaminase and lipids, liver lipids and serum proinflammatory cytokines. Moreover, the mRNA and protein expression and phosphorylation levels of key signaling molecules in the CCL2/CCR2-PI3K-Akt signal transduction pathway were obviously reduced by PTFC treatment. CONCLUSIVE REMARKS PTFC can ameliorate NASH symptoms, and the mechanism may be related to regulating the CCL2/CCR2-PI3K-Akt signal transduction pathway to reduce the liver inflammatory response.

Abstract
Background Chemokine (C–C motif) receptor 2 (CCR2) is involved in important physiological and pathological processes, such as inflammation and autoimmune diseases. Abnormal immune and inflammatory responses play a critical role in the development and progression of IgA nephritis (IgAN). However, the role of CCR2 in IgAN is unknown. Methods Fifteen IgAN children who were diagnosed by kidney biopsy provided kidney biopsy tissue, blood and urine samples, and age-matched healthy control subjects (blood donators n = 12; tissue donators n = 8) were included. Immunohistochemical analysis was used to detect the expression of CCR2, MCP-1, IL-6, IL-17, and TNF-α in the kidney tissues. Relative optical density (OD) was calculated by Image J software, and the correlation between CCR2 expression and pathological grade in IgAN children was analyzed. Results The expression of CCR2 significantly increased in mesangial cells of children with IgAN compared to that in control group (P < 0.001), especially in IgAN patients with Lee’s grade III to IV (P < 0.001). Interestingly, CCR2 expression was positively correlated with Lee’s grade (r = 0.9152, P = 0.0001) in IgAN children. The expression levels of inflammatory factors were markedly increased in IgAN children, and importantly CCR2 expression was positively correlated with it’s expression level. Conclusions The results suggest that CCR2 signaling might be involved in pathological process and inflammatory responses of children IgAN, and could potentially be an intervention target in children IgAN.

Abstract
Human hypofertility and infertility are two worldwide conditions experiencing nowadays an alarming increase due to a complex ensemble of events. The immune system has been suggested as one of the responsible for some of the etiopathogenic mechanisms involved in these conditions. To shed some light into the strong correlation between the reproductive and immune system, as can be inferred by the several and valuable manuscripts published to date, here we built a network using a useful bioinformatic tool (DisGeNET), in which the key genes involved in the sperm-oviduct interaction were linked. This constitutes an important event related with Human fertility since this interaction, and specially the spermatozoa, represents a not-self entity immunotolerated by the female. As a result, we discovered that some proteins involved in the sperm-oviduct interaction are implicated in several immune system diseases while, at the same time, some immune system diseases could interfere by using different pathways with the reproduction process. The data presented here could be of great importance to understand the involvement of the immune system in fertility reduction in Humans, setting the basis for potential immune therapeutic tools in the near future.

Abstract
Chronic low-grade inflammation in adipose tissue (AT) is a hallmark of obesity and contributes to various metabolic disorders, such as type 2 diabetes and cardiovascular diseases. Inflammation in ATs is characterized by macrophage infiltration and the activation of inflammatory pathways mediated by NF-κB, JNK, and NLRP3 inflammasomes. Adipokines, hepatokines and myokines - proteins secreted from AT, the liver and skeletal muscle play regulatory roles in AT inflammation via endocrine, paracrine, and autocrine pathways. For example, obesity is associated with elevated levels of pro-inflammatory adipokines (e.g., leptin, resistin, chemerin, progranulin, RBP4, WISP1, FABP4, PAI-1, Follistatin-like1, MCP-1, SPARC, SPARCL1, and SAA) and reduced levels of anti-inflammatory adipokines such as adiponectin, omentin, ZAG, SFRP5, CTRP3, vaspin, and IL-10. Moreover, some hepatokines (Fetuin A, DPP4, FGF21, GDF15, and MANF) and myokines (irisin, IL-6, and DEL-1) also play pro- or anti-inflammatory roles in AT inflammation. This review aims to provide an updated understanding of these organokines and their role in AT inflammation and related metabolic abnormalities. It serves to highlight the molecular mechanisms underlying the effects of these organokines and their clinical significance. Insights into the roles and mechanisms of these organokines could provide novel and potential therapeutic targets for obesity-induced inflammation.

Abstract
BACKGROUND AND PURPOSE Gestational diabetes mellitus (GDM) is a complication commonly observed in pregnancy, closely associated with increased oxidative stress, inflammatory response, and endoplasmic reticulum (ER) stress. Phoenixin-20 (PNX-20) is a newly reproductive hormone from the hypothalamus that has displayed pleiotropic effects. The promising inhibitory effects of PNX-20 on inflammation have recently been widely reported. The present study aims to investigate the protective effect of PNX-20 on GDM induced placental insults. METHODS A GDM model was established on C57BLKsJ db/+ mice. The expression level of GPR173 was evaluated using RT-PCR and western blotting analysis. The serum level of glucose, insulin, lipid profiles, and oxidative stress indicators were detected with commercial kits. Fetal analysis was performed to evaluate the reproductive ability. ELISA was used to detect the production of inflammatory factors. The expressions of p-eIF-2α, ATF4, and GRP78 were evaluated with western blotting assay. RESULTS Firstly, we found that GPR173 is expressed in the placenta tissue. Secondly, the elevated blood glucose level and lipid level, declined serum insulin level, fetus alive ratio, fetal and placenta weight, and shorten crown-rump length, were observed in the placenta tissue of GDM mice, which were reversed by treatment with PNX-20. Thirdly, the excessively released inflammatory factors and activated oxidative stress in GDM mice were alleviated by the administration of PNX-20. Lastly, the activated eIF-2α/ATF4 ER stress signaling pathway in GDM mice was dramatically suppressed by PNX-20. CONCLUSION Our data revealed a protective property of PNX-20 against placental insults resulted from GDM.
