Hypoxia is a common characteristic of many pathological and physiological conditions that can markedly change cellular metabolism and cause the accumulation of extracellular adenosine. Recent studies have shown that adenosine can modulate the function of certain immune cell types through binding with different adenosine receptors. Our previous studies have(More)
The involvement of the chemokine osteopontin has been proposed for maintaining successful pregnancy in mice and ruminants; however, little information of its function in human pregnancy is available. Osteopontin expression was assessed in decidua by RT-PCR and immunohistochemical staining in early pregnant women and RPL (recurrent pregnancy loss) patients.(More)
Studies of maternal-fetal tolerance focus on defining mechanisms for establishment of immunological privilege within the uterus during pregnancy. Fetal trophoblasts play a key role in maternal tolerance, in part through cytokines production. As a novel inhibitory cytokine, IL-35 is produced by Foxp3(+) regulatory T cells (Tregs) and mediates maximal(More)
As a biomaterial, chitosan has been widely used in tissue engineering, wound healing, drug delivery, and other biomedical applications. It can be formulated in a variety of forms, such as powder, film, sphere, gel, and fiber. These features make chitosan an almost ideal biomaterial in cell culture applications, and cell cultures arguably constitute the most(More)
Dihydroartemisinin (DHA), a semi-synthetic derivative and active metabolite of artemisinin, has been shown to have profound anticancer potential in addition to its strong anti-malarial activity. The purpose of the present study was to thoroughly investigate the anti-neoplastic effects induced by DHA and to provide(More)
It is well recognized that tissue microenvironments are involved in regulating the development and function of dendritic cells (DC). Oxygen supply, which varies in different tissues, has been accepted as an important microenvironmental factor in regulating the biological functions of several immune cells and as being involved in tumour progression and(More)
Fucoidan is a complex sulfated polysaccharide with a wide variety of biological activities for modulating immune cell functions. However, the effects of fucoidan on maturation process and activation of human monocyte-derived dendritic cells (DCs) remain to be elucidated. The present study demonstrated that the level of special marks and polarization(More)
BACKGROUND Vaccination could induce immune tolerance and protected NOD mice from the development of type I diabetes (T1D). We previously demonstrated that insulin peptide (B9-23) combined with dexamethasone (DEX) stimulated the expansion of antigen specific regulatory T (Treg) cells which in turn effectively prevented T1D in NOD mice. Here, we aimed to(More)
In the present study, a polysaccharide extract was obtained from Ocimum basilicum (basil polysaccharide, BPS) and the effects of curcumin and BPS on the invasion activity of the SKOV3 ovarian cancer cells and human monocyte-derived dendritic cells (DCs) were investigated. SKOV3 cells and immature or mature DCs were treated with 50 µM curcumin or 100 µg/ml(More)
Tissue inhibitor of metalloproteinase-3 (TIMP-3) is one of a family of proteins inhibiting matrix metalloproteinases, which has also been identified as a mediator for checking inflammation. Meanwhile, it is well known that inflammation causes the activation of the immune response. However, it is not clear whether TIMP-3 plays a role in the immune system. In(More)
