Senescence-associated secretory phenotype (SASP) is often a concomitant result of cell senescence, embodied by the enhanced function of secretion. The SASP factors secreted by senescent cells include cytokines, proteases and chemokines, etc, which can exert great influence on local as well as systemic environment and participate in the process of cell senescence, immunoregulation, angiogenesis, cell proliferation and tumor invasion, etc. Relative to the abundance of SASP models in human cells, the in vitro SASP model derived from mouse cells is scarce at present...

AIM: Anastomotic leak is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. We hypothesized that the infection-induced inflammatory response may induce overexpression of tumour progression-related genes in immune cells. The aim was to investigate the effect of postoperative intra-abdominal infection on the gene expression patterns of peripheral blood leukocytes (PBL) after surgery for colorectal cancer. METHODS: Prospective matched cohort study...

: Many goals in tissue engineering rely on modulating cellular localization and polarization of cell signaling, including the inhibition of inflammatory infiltrate, facilitation of inflammatory cell egress, and clearance of apoptotic cells. Omega-3 polyunsaturated fatty acid-derived resolvins are gaining increasing recognition for their essential roles in inhibition of neutrophil invasion into inflamed tissue and promotion of macrophage phagocytosis of cellular debris as well as their egress to the lymphatics...

Here, we characterize a subset of ILC3s that express Neuropilin1 (NRP1) and are present in lymphoid tissues, but not in the peripheral blood or skin. NRP1(+) group 3 innate lymphoid cells (ILC3s) display in vitro lymphoid tissue inducer (LTi) activity. In agreement with this, NRP1(+) ILC3s are mainly located in proximity to high endothelial venules (HEVs) and express cell surface molecules involved in lymphocyte migration in secondary lymphoid tissues via HEVs. NRP1 was also expressed on mouse fetal LTi cells, indicating that NRP1 is a conserved marker for LTi cells...

Mesenchymal stromal cells (MSCs) are considered adult progenitor stem cells and have been studied in a multitude of tissues. In this context, the microenvironment of nasal polyp tissue has several inflammatory cells, but their stroma compartment remains little elucidated. Hence, we isolated MSCs from nasal polyps Polyp-MSCs (PO-MSCs) and compared their molecular features and gene expression pattern with bone marrow-derived MSCs (BM-MSCs). Initially, both PO-MSCs and BM-MSCs were isolated, cultivated, and submitted to morphologic, differentiation, phenotypic, immunosuppressive, and gene expression assays...

The aim of the study was to identify significant abnormalities in angiogenic factor profiles occurring at early-stage non-small cell lung cancer (NSCLC). Contrary to the previous studies, our research included patients with only stage I NSCLC, which allowed for estimating the utility of circulating angiogenic factors in early NSCLC detection. The investigation was performed in serum samples collected from individuals with untreated NSCLC (n=41) and a matched control group of healthy individuals (n=61). All patients had histopathologically-confirmed stage IA or IB NSCLC...

Heart failure is a life-threatening disorder worldwide, and the current end-stage therapies for severe heart failure are replacement therapies such as ventricular-assist devices and heart transplantation. Although these therapies have been reported to be useful, there are many issues in terms of the durability, complications, limited donors, adverse effect of continuous administration of immunosuppressive agents, and high costs involved. Recently, regenerative therapy based on genetic, cellular, or tissue engineering techniques has gained attention as a new therapy to overcome the challenges encountered in transplantation medicine...

The human oncogenic virus Kaposi's sarcoma-associated herpesvirus (KSHV) is linked to Kaposi's sarcoma (KS), a tumor of endothelial cells characterized by angiogenesis and invasiveness. KSHV genome encodes 25 mature microRNAs (miRNAs), but their roles in KSHV-induced tumor dissemination and angiogenesis are not fully understood. In this study, we constructed the sensor reporters of KSHV miRNAs and used a luciferase reporter assay to demonstrate the function of the mimics of KSHV miRNAs. Then, we examined the expression of matrix metalloproteinases (MMPs) and pro-angiogenic cytokines that are related to cell migration and angiogenesis in the KSHV 25 miRNAs transfected endothelial cells...

Diabetic wound healing is a complicated process. In all over the world 15% of 200 million diabetic people suffer from diabetic foot problems. Mast cells are known to participate in three phases of wound healing: the inflammatory reaction, angiogenesis and extracellular-matrix reabsorption. The inflammatory reaction is mediated by released histamine and arachidonic acid metabolites. Omega-3 fatty acids alter proinflammatory cytokine production during wound healing which affects the presence of inflammatory cells in wound area as well, but how this events specifically influences the presence of mast cells in wound healing is not clearly understood...

BACKGROUND: In vitro and animal studies have linked neuroinflammation to Alzheimer's disease (AD) pathology. Studies on markers of inflammation in subjects with mild cognitive impairment or AD dementia provided inconsistent results. We hypothesized that distinct blood and cerebrospinal fluid (CSF) inflammatory markers are associated with biomarkers of amyloid and tau pathology in older adults without cognitive impairment or with beginning cognitive decline. OBJECTIVE: To identify blood-based and CSF neuroinflammation marker signatures associated with AD pathology (i...

The combination of mesenchymal stem cells and tissue-engineered fibrin patches improves the therapeutic efficacy of stem cells. In vivo cardiac magnetic resonance (4.7 Tesla) and ex vivo high-spatial resolution CMR were used to track the fate of human bone marrow-derived mesenchymal stem cell (BMSC) delivered on an epicardial scaffold and more specifically assess their potential intramyocardial migration. Fifty-seven nude rats underwent permanent coronary artery ligation. Two months later, those with a left ventricular ejection fraction ≤55% were randomly allocated to receive a patch loaded with human BMSC (BMSC-P, n = 10), a patch loaded with BMSCs labelled with iron oxide nanoparticles (BMSC*-P, n = 12), an acellular patch (A-P, n = 8) or to serve as sham-operated animals (SHAM, n = 7)...

Cells constantly adapt to external humoral cues like cytokines and hormones, but practically most cellular behavior is under locally guided control via cell-cell interactions. Galectins (Gals) are one of the most prominent members of the group of molecules involved in this intercellular signaling. They are the family of β-galactoside specific lectins and consist of 15 different types, each with a specific function. They play crucial role in the immune system, inflammation, wound healing and carcinogenesis...

Stem cell factor (SCF) is a multifunctional cytokine responsible for tumorigenesis and progression. In this study, we report that increased expression of SCF in hepatocellular carcinoma (HCC) patients is highly associated with metastasis and poor prognosis. SCF inhibition with RNAi inhibited HCC cell migration, invasion in vitro, and reduced intrahepatic metastases burden and significantly prolonged survival in a HCC xeograft mouse model. SCF depletion in HCC xeograft decreased the expression of vimentin and increase the expression of E-cadherin, implicating a role for SCF in epithelial-mesenchymal transition...

Pro-inflammatory cytokines in the tumor microenvironment are known for their ability to either inhibit or promote cancer progression. Here we evaluated the role of Interleukin-31 (IL31), a protein belonging to the pro-inflammatory IL-6 cytokine family which has been characterized in autoimmune disease, in tumorigenesis. We show that IL31 and its receptor, IL31RA, are highly expressed in various human and mouse cancer cell lines, as well as in tumor specimens from cancer patients. MC38 murine colon carcinoma cells depleted of IL31 exhibit an increase in invasive and migratory properties in vitro, effects that are reversed by supplementing the cells with exogenous IL31...

BACKGROUND: Sepsis is characterized by an early systemic inflammation in response to infection. In the brain, inflammation is associated with expression of pro-inflammatory cytokines (e.g. tumor necrosis factor-α, interleukin-1β and interleukin-6, among others) that may induce an overproduction of reactive oxygen and nitrogen species. The constitutive expression of cytokines in the brain is low, but may be induced by various stimuli, including lipopolysaccharide, which causes neuronal damage...

BACKGROUND: Adequate vascularization is crucial for supplying nutrition and discharging metabolic waste in freshly transplanted tissue-engineered constructs. Obtaining the appropriate building blocks for vascular tissue engineering (i.e. endothelial and mural cells) is a challenging task for tissue neovascularization. Hence, we investigated whether stem cells from human exfoliated deciduous teeth (SHED) could be induced to differentiate into functional vascular smooth muscle cells (vSMCs)...
