Endothelial cell (EC) released microvesicles (EMVs) can affect various target cells by transferring carried genetic information. Astrocytes are the main components of the blood brain barrier (BBB) structure in the brain and participate in regulating BBB integrity and blood flow. The interactions between ECs and astrocytes are essential for BBB integrity in(More)
An immunotoxin, SOKT1-RTA, was prepared successfully by conjugating a murine anti-human T lymphocyte monoclonal antibody (McAb) SOKT1 and the ricin toxin A chain (RTA) with the heterobifunctional linker SPDP. At the presence of 20 mmol/L NH4Cl, the SOKT1-RTA conjugate killed 82% of the human peripheral blood T cells (PBT), and decreased their 3H-Leu(More)
Multilayer composite membrane of biomaterials can increase the function of adipose stem cells or osteoprogenitor cells. Recent evidence indicates endothelial progenitor cells (EPCs) and EPCs released microvesicles (MVs) play important roles in angiogenesis and vascular repair. Here, we investigated the effects of biomaterial multilayer membranes of(More)
Hepatic stellate cells (HSCs), previously described for liver-specific mesenchymal stem cells (MSCs), appear to contribute to liver regeneration. Microvesicles (MVs) are nanoscale membrane fragments, which can regulate target cell function by transferring contents from their parent cells. The aim of this study was to investigate the effect of HSC-derived(More)
Hebdomadis is one of the major serogroups found in China. In Sichuan, this serogroup appears to have a close relationship with local outbreak of leptospirosis. BALB/c mice were immunized intrasplenically with outer envelope of serogroup Hendomadis serovar hebdomadis strain 245. Spleen cells were fused with SP2/0 myeloma cells, two monoclonal antibodies Af2(More)
SOKT1 -RTA immunotoxin, which consisted of an anti-pan-T cell monoclonal antibody SOKT1 and ricin toxin A-chain, decreased the peripheral blood lymphocyte transformation in response to PHA and to alloantigen by 92.9% and 84.7%, respectively. The generation of allocytotoxic T cell was also dramatically inhibited by this immunotoxin. After treatment of human(More)
