Abstract
Women are at increased risk for developing depression and cardiovascular disease (CVD) across the lifespan and their comorbidity is associated with adverse outcomes that contribute significantly to rates of morbidity and mortality in women worldwide. Immune-system activity has been implicated in the etiology of both depression and CVD, but it is unclear how inflammation contributes to sex differences in this comorbidity. This narrative review provides an updated synthesis of research examining the association of inflammation with depression and CVD, and their comorbidity in women. Recent research provides evidence of pro-inflammatory states and sex differences associated with alterations in the hypothalamic–pituitary–adrenal axis, the renin–angiotensin–aldosterone system and the serotonin/kynurenine pathway, that likely contribute to the development of depression and CVD. Changes to inflammatory cytokines in relation to reproductive periods of hormonal fluctuation (i.e. the menstrual cycle, perinatal period and menopause) are highlighted and provide a greater understanding of the unique vulnerability women experience in developing both depressed mood and adverse cardiovascular events. Inflammatory biomarkers hold substantial promise when combined with a patient’s reproductive and mental health history to aid in the prediction, identification and treatment of the women most at risk for CVD and depression. However, more research is needed to improve our understanding of the mechanisms underlying inflammation in relation to their comorbidity, and how these findings can be translated to improve women’s health.

Abstract
The study aimed to study the correlation between expression levels of interleukin-37 (IL-37), granulocyte macrophage colony-stimulating factor (GM-CSF), and C-reactive protein (CRP) in peripheral blood and the status of atherosclerosis (AS) and plaque stability and to confirm the clinical significance of these inflammatory factors in the pathogenesis of AS. A total of 64 AS patients (case group) were selected and divided into unstable plaque group (group A, 28 cases) and stable plaque group (group B, 36 cases) according to the color ultrasonography results of arterial vessels. At the same time, 30 healthy subjects were classified into the control group. General information of the enrolled subjects was collected, including levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), CRP, and homocysteine (Hcy). The expression levels of IL-37 and GM-CSF in the serum of peripheral blood samples collected from these subjects were measured by enzyme-linked immunosorbent assay (ELISA). There was no significant difference between the case group and the control group in the levels of TC, TG, HDL, and LDL ( P > 0.05). However, the expression level of Hcy in the case group was significantly higher than that in the control group ( P < 0.05). Compared with the control group, the expression levels of IL-37, GM-CSF, and CRP in the case group were significantly increased ( P < 0.05). In addition, compared with group B, the expression level of GM-CSF in group A was significantly increased ( P < 0.05), while no significant difference was detected between group A and group B in the expression levels of IL-37 and CRP ( P > 0.05). In conclusion, inflammatory factors IL-37, GM-CSF, CRP, and Hcy were all involved in the pathogenesis of AS, and the increased levels of GM-CSF were closely related to the progress of unstable plaques. These results may aid the early diagnosis/treatment of AS.

Abstract
This study investigated whether aging was associated with epigenetic changes of DNA hypermethylation on immune gene expression and lymphocyte differentiation. We screened CG sites of methylation in blood leukocytes from different age populations, picked up genes with age-related increase of CG methylation content more than 15%, and validated immune related genes with CG hypermethylation involved in lymphocyte differentiation in the aged population. We found that 12 genes (EXHX1、 IL-10、 TSP50、 GSTM1、SLC5A5、SPI1、F2R、LMO2、PTPN6、FGFR2、MMP9、MET) were associated with promoter or exon one DNA hypermethylation in the aged group. Two immune related genes, GSTM1 and LMO2, were chosen to validate its aging-related CG hypermethylation in different leukocytes. We are the first to validate that GSTM1_P266 and LMO2_E128 CG methylation contents in T lymphocytes but not polymorphonuclear cells (PMNs) or mononuclear cells (MNCs) were significantly increased in the aged population. The GSTM1 mRNA expression in T lymphocytes but not PMNs or MNCs was inversely associated with the GSTM1 CG hypermethylation levels in the aged population studied. Further studies showed that lower GSTM1 CG methylation content led to the higher GSTM1 mRNA expression in T cells and knockdown of GSTM1 mRNA expression decreased type 1 T helper cell (Th1) differentiation in Jurkat T cells and normal adult CD4 T cells. The GSTM1_P266 hypermethylation in the aged population associated with lower GSTM1 mRNA expression was involved in Th1 differentiation, highlighting that modulation of aging-associated GSTM1 methylation may be able to enhance T helper cell immunity in the elders.

Abstract
BACKGROUND AND AIM Disturbance in the carotid arteries strongly predicts cerebrovascular events and correlates with a systemic inflammatory milieu. We investigated the relationship of a profile of 10 circulating inflammatory mediators with measures of carotid intima-media thickness (cIMT) in elderly subjects, taking traditional risk factors into account. METHODS Clinical inspection for present and past chronic conditions and events, as well as biochemical and anthropometric measurements, was performed for patients in ambulatory setting. Scores of cIMT were obtained bilaterally in the distal common carotid artery wall. Serum concentrations of cytokines were assessed by bead-based, multiplexed flow cytometry immunoassays. RESULTS Correlation analysis between log-transformed cytokines levels implicated the mediators interleukin-1β (IL1β), IL6, IL8, IL10, and tumor necrosis factor-α (TNFα) (P ≤ .005) with scores of the left cIMT. Stepwise multivariate regression showed that TNFα, IL1β, and IL6 levels accounted for most of the variance in the cIMT scores. Comparison of cytokine levels across increasing tertiles of the left cIMT reproduced the positive association with TNFα and IL1β levels. CONCLUSION Five out of ten immune mediators independently correlated with cIMT of older subjects in a territory-sensitive manner. This possible contribution of immune mediators to an atherosclerotic process probably relates to the inflammaging process.

Abstract
Corneal alkali burns (CAB) are characterized by injury-induced inflammation, fibrosis and neovascularization (NV), and may lead to blindness. This review evaluates the current knowledge of the molecular mechanisms responsible for CAB. The processes of cytokine production, chemotaxis, inflammatory responses, immune response, cell signal transduction, matrix metalloproteinase production and vascular factors in CAB are discussed. Previous evidence indicates that peroxisome proliferator-activated receptor γ (PPAR-γ) agonists suppress immune responses, inflammation, corneal fibrosis and NV. This review also discusses the role of PPAR-γ as an anti-inflammatory, anti-fibrotic and anti-angiogenic agent in the treatment of CAB, as well as the potential role of PPAR-γ in the pathological process of CAB. There have been numerous studies evaluating the clinical profiles of CAB, and the aim of this systematic review was to summarize the evidence regarding the treatment of CAB with PPAR-γ agonists.

Abstract
AIM This study aimed to assess whether the habitual intake of macronutrients by older women associates with circulating levels of important inflammaging mediators by means of a cross-sectional design with 229 Brazilian elderly women. METHODS Laboratory tests determined serum IL1α, IL1β, IL6, IL8, IL10, IL12 and TNFα by specific immunoassays. Food records of three alternate days were decomposed into usual intake of carbohydrates, proteins and lipids (and fractions), as well as total energy value (TEV) per patient. Moreover, the study has identified and controlled results for metabolic conditions known to influence the inflammatory profile: hypercholesterolemia, hypertension and diabetes. RESULTS AND DISCUSSION Pearson's correlation test revealed that log10IL8 expressed a positive association with levels of saturated fatty acid (FA) (r = 0.173; p = 0.009) and total cholesterol intake (r = 0.223; p = 0.001). Similar analysis of the other mediators revealed no association with dietary intake. CONCLUSION Higher intakes of total cholesterol and saturated FA seem to correlate with increased serum IL8 levels, being a possible mechanism by which this pro-atherogenic intake pattern may increase the risk of age-related chronic diseases with important inflammatory contribution.

Abstract
Atherosclerosis is the major cause of myocardial infarction and stroke, which is a leading cause of morbidity and mortality in developed countries. During the pathological process of atherosclerosis, inflammation participates in all stages of atherosclerosis. Tumor necrosis factor-α (TNF-α), one of the most important inflammatory factor, induces apoptosis of endothelial cells, which play a central role in endothelial dysfunction. However, the underlying mechanism involved in long noncoding RNA (lncRNA) remains unclear. In the present study, we demonstrated the role of lncRNA highly upregulated in liver cancer (HULC) in TNF-α-induced apoptosis. HULC expression was decreased with TNF-α treatment. Restoring HULC expression rescued the apoptosis induced by TNF-α. HULC regulated TNF-α-induced apoptosis through regulation of miR-9 expression. Furthermore, RNA immunoprecipitation and RNA pull-down assays showed that HULC modulated miR-9 expression through association with DNA methyltransferases and suppression of miR-9 expression. HULC-miR-9 pathway may be a potential target for treating atherosclerosis.
