Graft-versus-host disease (GVHD) is a frequent and life threatening complication of allogeneic haematogenesis stem cell transplantation (aHSCT). The correlation of CD4(+)CD25(+) regulatory T cells (Tregs) in the patients after aHSCT to the occurrence and severity of acute and chronic GVHD (aGVHD and cGVHD) is not fully investigated. Here, we examined the(More)
Recently, Th17 cell-associated responses have received growing attention; however, the role of IL-22 (a cytokines also produced by Th17 cells) in the pathogenesis of systemic lupus erythematosus (SLE) has not been widely explored. In this study, we analyze the frequencies of IL-22-positive CD4+/CD8+ T cells in peripheral blood mononuclear cells (PBMCs) from(More)
Cytokine-induced killer (CIK) cells are usually generated from peripheral blood mononuclear cells with the stimulation of IL-2 in vitro. Unlike the conventional IL-2-stimulated CIK cells (IL-2-CIK cells), we investigated the characteristics and potential mechanism of IL-15-stimulated CIK cells (IL-15-CIK cells) in this study. Compared with IL-2-CIK cells,(More)
Regulatory T cells (Tregs) are potent immunosuppressive cells that promote tumor growth and invasion by inducing immune escape and suppressing the antitumor immune response. Cytokine-induced killer (CIK) cells are considered to be the primary candidate for adoptive immunotherapy due to their strong antitumor activity. It was recently reported that the(More)
Glucocorticoids (GCs) are frequently used to treat many of the acute disease manifestations associated with inflammatory and autoimmune disorders. However, Toll-like receptor (TLR) pathway-activated plasmacytoid dendritic cells (pDCs) are resistant to GC-induced apoptosis, which leads to the inefficiency of GCs in the treatment of type I interferon-related(More)
OBJECTIVE To investigate the abnormalities of T regulatory cells (Treg) in salivary glands and peripheral blood in patients with primary Sjögren's syndrome (pSS). METHODS Levels of CD4+CD25+ high T cells of the peripheral blood of 52 patients with pSS were measured by flow-cytometric assay. Lower lip salivary gland biopsies were examined by(More)
OBJECTIVE To detect the new and old surface markers of regulatory T cells (Treg cells) in the CD4+ T cells of the patients with systemic lupus erythematosus (SLE) in order to reveal the role of Treg cells in the pathogenesis of SLE. METHODS Peripheral blood samples were collected from 29 newly diagnosed and treatment-naïve SLE patients, 3 males and 26(More)
Regulatory T cells (Tregs) are potent immunosuppressive cells and essential for inducing immune tolerance. Recent studies have reported that Tregs and Tregs related cytokines can inhibit the antitumor activity of cytokine-induced killer (CIK) cells, but dendritic cells co-cultured CIK (DC-CIK) cells can be used for induction of a specific immune response by(More)
We retrospectively evaluated the association between the expression of CD56 and CD117 on neoplastic plasma cells and patients prognosis in 50 newly diagnosed multiple myeloma (MM) patients. The overall survival (OS) was measured and Cox proportional hazards model was used to evaluate CD56 and CD117 as possible prognostic factors for OS. CD56+ and CD117+(More)
To determine whether peripheral blood absolute lymphocyte/absolute monocyte counts ratio (ALC/AMC ratio) at diagnosis predicts survival of diffuse large B cell lymphoma (DLBCL) patients treated with standard first-line regimens, we retrospectively analyzed 244 patients with DLBCL who were treated with standard cyclophosphamide, hydroxydaunorubicin,(More)
