Ventricular dysfunction is common among patients with repaired cyanotic congenital heart disease. To date, no pharmacologic intervention has been demonstrated to be beneficial in this setting. To begin addressing this knowledge gap, we conducted a single-center prospective, randomized, open-label pilot study to investigate the effects of eplerenone on serologic markers of collagen turnover and inflammation, 6-minute walk distance, and quality of life in patients with tetralogy of Fallot (TOF) or transposition of the great arteries with a systemic right ventricle (transposition of the great arteries [TGA])...

BACKGROUND: Plasma Galectin-3 is a marker of myocardial inflammation and fibrosis, was associated with left ventricular (LV) reverse remodeling after conventional surgical mitral valve repair (MVR) and predicted clinical events in patients undergoing transcatheter aortic valve replacement (TAVR). We aimed to evaluate the association between pre-interventional Galectin-3 levels and (1) reverse LV remodeling and (2) major adverse cardiovascular events (MACE) in patients undergoing percutaneous MVR...

We have set up an ex vivo ovine abomasal model, which can mimic the multicellular process to explore the early steps in haemonchine nematode infection using RNA-seq technology. Ovine abomasal explants were collected for histological and transcriptional analysis and supernatants collected to quantitate lactate dehydrogenase (LDH) enzymes. Atotal of 233 were substantially induced genes between L4 -inoculated and uninoculated-control tissues, respectively. However, a total of 14 were considerably down-regulated genes between the 51 aforementioned tissues...

Recurrent miscarriage is defined as the loss of 3 or more consecutive pregnancies; however, the underlying immunologic mechanisms that trigger pregnancy loss remain largely unelucidated. Galectin-9 (Gal-9) may modulate a variety of biologic functions and play an important role in Th1/Th2 immune deviation. To analyze the mechanism of Gal-9 in abortion, we used the classical abortion-prone mouse model (DBA/2-mated CBA/J mice) to detect the expression of Gal-9 at the maternal-fetal interface. We also mimicked the immune environment of pregnancy by culturing trophoblast cells with peripheral blood mononuclear cells (PBMCs) to explore how Gal-9 might be involved in the pathogenesis of abortion...

In this issue of Molecular Cell, Jia et al. (2018) identify a lysosomal damage-response pathway centered on galectin 8 and 9 that feeds back on mTORC1 signaling. In response to lysosome-damaging agents, galectins inhibits mTORC1, triggering a stress response that may help restore cellular homeostasis.

The Ser/Thr protein kinase mTOR controls metabolic pathways, including the catabolic process of autophagy. Autophagy plays additional, catabolism-independent roles in homeostasis of cytoplasmic endomembranes and whole organelles. How signals from endomembrane damage are transmitted to mTOR to orchestrate autophagic responses is not known. Here we show that mTOR is inhibited by lysosomal damage. Lysosomal damage, recognized by galectins, leads to association of galectin-8 (Gal8) with the mTOR apparatus on the lysosome...

Expression of immune checkpoint molecules, including programmed cell death protein-1 (PD-1), has been reported on T cells in various types of cancer. However, the expression status of these molecules in the tumor microenvironment of epithelial ovarian cancer (EOC) has not yet been studied. A total of 54 cases of malignant ascites from patients with EOC were analyzed in the present study. The expression of PD-1, lymphocyte-activation gene-3 (LAG-3), T-cell immunoglobulin and mucin-domain containing-3 (TIM-3) and B and T lymphocyte attenuator (BTLA) on cluster of differentiation (CD)4+ and CD8+ T cells in malignant EOC ascites were investigated using multicolor flow cytometric analysis...

Uncontrolled secretion of type I IFN, as the result of endosomal TLR (i.e., TLR7 and TLR9) signaling in plasmacytoid DCs (pDCs), and abnormal production of autoantibodies by B cells are critical for systemic lupus erythematosus (SLE) pathogenesis. The importance of galectin-9 (Gal-9) in regulating various autoimmune diseases, including lupus, has been demonstrated. However, the precise mechanism by which Gal-9 mediates this effect remains unclear. Here, using spontaneous murine models of lupus (i.e., BXSB/MpJ and NZB/W F1 mice), we demonstrate that administration of Gal-9 results in reduced TLR7-mediated autoimmune manifestations...

Inflammation, apoptosis and extracellular remodeling play significant roles in cardiovascular disease (CVD) underlying the major causes of mortality in renal patients. In 19 pre-dialysis patients, 21 dialysis patients and 20 control subjects, the concentrations of pentraxin-3, galectin-3, MMP-9 and TIMP-1 were determined by ELISA. CVD risk was calculated according to the Framingham risk score algorithm. Pentraxin-3 was increased in renal patients compared to healthy controls (p<0.001). In contrast, galectin-3 was reduced in hemodialysis patients compared to pre-dialysis patients and controls (p<0...

The aim of the study was to study the effect of carbohydrate metabolism disturbances and other factors on the level of new biomarkers of P-selectin and Galectin-3 inflammation in patients with stable angina. The study included 119 patients with angina with or without diabetes mellitus, as well as patients with type 2 diabetes. Patients included in the study were tested in addition to standard methods to determine the levels of new biomarkers of inflammation of P-selectin, Galectin-3 and hs-CRP. The data obtained showed that the levels of P-selectin and Galectin-3 in patients with stable angina are interrelated, but vary significantly at the individual level, with both biomarkers of inflammation not associated with hs-CRP, which creates the prerequisites for the personalization of therapeutic goals in reducing the systemic inflammatory response...

OBJECTIVE: Cardiac resynchronization therapy (CRT) induces structural and electrical reverse remodeling of the failing heart. However, the association between native QRS narrowing and cardiac fibrosis markers has not been investigated in patients with an implanted CRT device. METHODS: A total of 41 symptomatic patients diagnosed with systolic heart failure who underwent CRT implantation were included in this study. Electrocardiogram findings and cardiac fibrosis marker levels [galectin-3, growth-differentiation factor-15 (GDF-15) and procollagen III N-terminal propeptide (P3TD)] were collected before and 12 months after initiation of biventricular pacing...

Endometriosis, although not malignant, has clinically demonstrated properties of invasiveness and metastasis. The pathogenesis of endometriosis, however, has not yet been elucidated. The immunological differences between endometriosis and malignant gynecologic tumors were analyzed by assessing C-type lectin receptors, which are associated with innate immunity, and immunoglobulin secretion, which is associated with B cell adaptive immunity, in the peritoneal fluid of these patients. Peritoneal fluid samples were obtained from 42 patients with benign masses (control group), 38 with endometriosis, and 43 with gynecologic (ovarian, uterine, and cervical) cancers...

BACKGROUND: T-cell immunoglobulin mucin 3 (TIM3) is a negative immune checkpoint and plays a crucial part in tumor-induced immune suppression. However, the mechanism of TIM3 in regulating immunosuppression in head and neck squamous cell carcinoma (HNSCC) was still not quite clear. METHODS: We carried out the immunohistochemistry staining of HNSCC tissue microarrays. Through quantification of the histoscore, we performed the correlation analysis among the TIM3, Galectin-9, Foxp3, CD68 and CD163...

Galectin-9 consists of two peptide-linked carbohydrate recognition domains (CRDs), but alternative splicing and proteolytic processing can give rise to multiple galectin-9 isoforms. Some of these consist of a single CRD and can exert different functions in cell biology. Here, we explored the role of these galectin-9 isoforms in endothelial cell function and angiogenesis. For this, we compared the effects of the two separate CRDs (Gal-9N and Gal-9C) with the tandem repeat galectin-9M on endothelial cell proliferation, migration, sprouting and tube formation in vitro as well as on angiogenesis in vivo using the chicken chorioallantoic membrane (CAM) assay...

OBJECTIVE: In systemic lupus erythematosus (SLE), an autoimmune disease associated with multiple organ involvements, lupus nephritis determines prognosis and arthritis impairs quality of life of patients. Galectin-9 (Gal-9, Lgals9) is a β-galactoside binding lectin and the attempts for its clinical application have been made in autoimmune diseases, since recombinant Gal-9 as a ligand for Tim-3 induces apoptosis in activated CD4+ Tim-3+ Th1 cell. We investigated wethere the deficiency of Lgals9 is beneficial or deleterious in lupus mice models...

Galectin-9 is a b-galactoside-binding tandem repeat galectin that regulates many cellular functions, ranging from cell adhesion to pathogen recognition. In spite of extensive study of mammalian galectin importance in immune system, little is known about that of fish. To study the normal expression and immune response of Labeo rohita to pathogens, a tandem-repeat galectin-9 from Labeo rohita was identified and named LrGal-9. Its full-length cDNA was 1534 bp encoded 291 amino acids (35.12 KDa), shared the highest 81% identity with the galectin-9 of Danio rerio...

Impairment of the intestinal mucosal immunity significantly increases the risk of acute and chronic diseases. Immunoglobulin A (IgA) plays a major role in humoral mucosal immunity to provide protection against pathogens and toxins in the gut. Here, we investigated the role of endogenous galectin-9, a tandem repeat-type β-galactoside-binding protein, in intestinal mucosal immunity. By mucosal immunization of Lgals9-/- and littermate control mice, it was found that lack of galectin-9 impaired mucosal antigen-specific IgA response in the gut...

Differential diagnosis for neuromyelitis optica spectrum disorder (NMOSD) and multiple sclerosis (MS) is always doubtful. To differentiate these diseases, we studied the immune status in the blood of patients with MS (n = 45) or NMOSD (n = 23) at remission phase. Remitting NMOSD patients had increased levels of CXCL13 and memory B cells, while remitting MS patients had elevated levels of galectin-9 and Th1 cells. A diagnostic model with these four variables is built to distinguish remitting NMOSD from MS with a sensitivity of 91...
