BACKGROUND Regulatory B cells (Breg) are a distinct B cell subset with immunoregulatory properties. Pivotal to Breg function is interleukin-10. This study was to investigate the role of IL-10-producing B cell (B10) and its association with Treg and Th17 subsets in immune thrombocytopenia (ITP) patients. METHODS Peripheral blood mononuclear cells from ITP(More)
BACKGROUND & AIMS Thrombocytopaenia is a frequent feature in patients with HBV-related liver disease. Its underlying mechanism is not fully understood. Multiple factors might contribute to the development of thrombocytopaenia. In this study, we investigated the reticulated platelets (RP), glycocalicin (GC), serum thrombopoietin (TPO) and platelet(More)
Primary immune thrombocytopenia (ITP) is an autoimmune heterogeneous disorder which is characterized by decreased platelet count. Serum cytokines play an important role in the pathogenesis of ITP by initiating and perpetuating various cellular and humoral autoimmune processes. To investigate a broad spectrum of cytokines in ITP patients and the effects of(More)
Primary immune thrombocytopenia (ITP) is an autoimmune heterogeneous disorder. Excessive activated CD4(+) T effector cells (Teffs) and compromised regulatory T cells (Tregs) were reported in ITP patients, yet little is known about the mechanisms. Interleukin-10 (IL-10) is an important regulatory cytokine of Tregs in inflammatory condition. It has been(More)
OBJECTIVE To assess the effect and complications of open splenectomy (OS) for immune thrombocytopenic purpura (ITP) and determine preoperative factors associated with surgical effect. METHODS This was a retrospective analysis of ITP patients who failed medical therapy and were treated with OS between 1997 and 2014 at the Jinshan Hospital, China. Follow-up(More)
BACKGROUND Primary immune thrombocytopenia (ITP) is an autoimmune heterogeneous disorder that is characterized by decreased platelet count. Regulatory T (Treg) cells and T helper type 17 (Th17) cells are two subtypes of CD4(+) T helper (Th) cells. They play opposite roles in immune tolerance and autoimmune diseases, while they share a common differentiation(More)
B cells expressing CD5 are potentially capable of producing interleukin 10 (IL-10) which contributes to the regulatory function of B cells. This study was aimed at exploring the alteration of numbers of CD5+ B cells and their ability of producing IL-10 in patients with immune thrombocytopenia (ITP), and the effects of pulsed high-dose dexamethasone (HD-DXM)(More)
Primary immune thrombocytopenia (ITP) is an autoimmune heterogeneous disorder that is characterized by decreased platelet count. The interleukin-23 receptor (IL-23R) has been identified as a susceptibility gene for the development of multiple autoimmune diseases. To investigate the possible association of IL-23R gene single-nucleotide polymorphisms (SNPs)(More)
BACKGROUND B cells play a critical role in the pathogenesis of immune thrombocytopenia (ITP), and toll-like receptor (TLR) signaling is essential for the activation of autoreactive B cells. The objective of this study was to investigate the expression profile of TLR signaling molecules in circulating and splenic CD19(+) B cells isolated from ITP patients.(More)
