Abstract The endothelial glycocalyx, located at the luminal surface of endothelium, plays an important role in regulation leukocyte adhesion, vascular permeability, and homeostasis. Endomucin (EMCN), a component is mucin-like transmembrane glycoprotein selectively expressed by venous capillary endothelium. We have previously shown that knockdown EMCN impairs retinal development vivo growth factor 165 isoform (VEGF165)-induced cell migration, proliferation, tube formation human cells vitro...

The increased PD-L1 expression induces poorer prognosis in melanoma. small molecule inhibitors of PD-1/PD-L1 pathways have been an encouraging drug development strategy because good affinity and oral bioavailability without immunogenicity immunotoxicities antibodies. In this study, we studied the effects PCC0208025 (BMS202), a inhibitor PD-L1, on binding cytokines secretion human CD3+ cells vitro. We also investigated antitumor immunomodulatory activity pharmacokinetics properties B16-F10...

We have previously shown that knockdown of endomucin (EMCN), an integral membrane glycocalyx glycoprotein, prevents VEGF-induced proliferation, migration, and tube formation in vitro angiogenesis vivo. In the endothelium, VEGF mediates most its angiogenic effects through receptor 2 (VEGFR2). To understand role EMCN, we examined effect EMCN depletion on VEGFR2 endocytosis activation. Results showed although stimulation promoted internalization control endothelial cells (ECs), loss prevented...

Connexins play essential roles in lens homeostasis and development. Here, we identified a new role for Cx50 that mediates cell-cell adhesion function. enhanced the adhesive capability of AQP0. Interestingly, expression alone promoted cell at comparable level to AQP0; however, this function was not observed with other connexins, Cx43 Cx46. Moreover, property occurred both homotypic expressed pairing cells heterotypic only one cell, appears be unrelated its forming gap junction channels. KO...

Tris-(2,3-dibromopropyl) isocyanurate (TDBP-TAZTO), an emerging brominated flame retardant, possesses the characteristics of candidate persistent organic pollutants and has displayed toxicity to fish rodents. TDBP-TAZTO can pass through blood brain barrier accumulate in brain. However, neurotoxicity not yet studied We hypothesize that could induce rat hippocampal neurons. The male adult rats were exposed 5 50 mg/kg by gavage, daily for 6 months. resulted cognitive impairment depression-like...

The increased PD-L1 induces poorer prognosis in melanoma. treatment with PD-1/PD-L1 antibodies have a low response rate. combination immunotherapies are the encouraging drug development strategy to receive maximal therapeutic benefit. In this study, we investigated enhanced antitumor and immunomodulatory activity of combined SEP αPD-L1 B16-F10 melanoma-bearing mice. results shown that presented significant synergistic effects, frequency CD8+ CD4+ T cells spleen tumor, cytotoxic CTL spleen,...

Endomucin (EMCN) is the type I transmembrane glycoprotein, mucin-like component of endothelial cell glycocalyx. We have previously shown that EMCN necessary for vascular growth factor (VEGF)-induced VEGF receptor 2 (VEGFR2) internalization and downstream signaling. To explore structural components are its function molecular mechanism in VEGF-induced functions, we generated a series mouse truncation mutants examined their ability to rescue functions human primary cells (EC) which endogenous...

Galectin-3 (Gal3) is a carbohydrate-binding protein reported to promote angiogenesis by influencing vascular endothelial growth factor-A receptor 2 (VEGFR2) signal transduction. Here we evaluated whether the ability of Gal3 function as an angiogenic factor involved (VEGF). To address this possibility used human retinal microvascular cells (HRECs) determine exogenous requires VEGF activate VEGFR2 signaling and if required for VEGFR2. phosphorylation HREC migration assays, following either...

Endomucin (EMCN), an endothelial-specific glycocalyx component, was found to be highly expressed by the endothelium of renal glomerulus. We reported anti-inflammatory role EMCN and its involvement in regulation vascular endothelial growth factor (VEGF) activity through modulating VEGF receptor 2 (VEGFR2) endocytosis. The goal this study is investigate phenotypic functional effects deficiency using first global knockout mouse model.
