in this study, the milk-derived galactooligosaccharides (gos) were produced by lactobacillus delbrueckii subsp. bulgaricus and refined by an ultrafiltration-nanofiltration continuous membrane. by further investigation, we found that the gos product purified by gel permeation chromatography mainly contained low molecular weight disaccharide and trisaccharide, that is, 4-β-galactobiose and tri-ga...
background: mesenchymal stem cells (msc) have ability to regulate immune response via proinflamatory cytokines. in this study we aimed to investigate the effect of different mechanism for t cell activation and adjacency on immunoregulatory properties of msc. methods: bone marrow mscs were purchased and t cells were obtained from whole blood sample. t cells were activated by two different mechan...
We have described an interaction between two T cells subsets that results in interference with the expression of Ly-1-, 2+ (Ly-2) T cell-mediated suppression. We refer to this novel immunoregulatory activity as contrasuppression. The T cell responsible for the induction of contrasuppression (inducer cell) expresses the phenotype Ly-1-, 2+;I-J+;Qa-1+. This phenotype distinguishes it from the sup...
Mesenchymal stem cells (MSCs) are well known due to their immunomodulatory effect, but the exact mechanisms have not been defined. Several studies demonstrated that the exerted immunoregulatory effect of these cells could be mediated by paracrine factors to illustrate, cytokines, chemokine, and among which, extracellular vesicles are one of them to play a crucial role. Moreover, it is assumed t...
