Specific T cell cytotoxicity to Epstein-Barr virus (EBV) infected B cells is reported to be abnormal in rheumatoid arthritis (RA). The regression phenomenon was used to determine whether the immunoregulatory defect in RA is restricted to T cells, B cells, or HLA type. Peripheral blood T and B cells from patients with RA and their HLA identical healthy siblings were mixed in varying ratios with ...
hematopoietic cord blood (cb) stem cell transplantation has more advantages to other cell sources because of lower graft versus host disease (gvhd). interleukin-15(il-15) is an immunoregulatory cytokine, known to enhance cytolytic function of cord natural killer (nk) cells. the aim of this study was to investigate the effect of il-15 on nk cytotoxicity simultaneously in different cell death sta...
BACKGROUND Mesenchymal stem cells (MSC) play important roles in modulating the activities of T lymphocytes, dendritic cells and natural killer cells. These immunoregulatory properties of MSC suggest their therapeutic potential in autoimmune diseases. However, the effects of MSC on B cells are still poorly understood. The present study was designed to investigate the interaction between MSC and ...
A new heteropolysaccharide was isolated from the fruiting bodies of Tricholoma matsutake which had a molecular weight of 12078 Da. The results of structural features analysis showed that T. matsutake polysaccharide, here named TMP-B, was mainly composed of α - D - glucose and α - D - galactose which ratios were 7:2 and had a backbone of 1, 4 - linked α - D - glucose which branches were mainly c...
