Humanized anti-CD123 antibody facilitates NK cell antibody-dependent cell-mediated cytotoxicity (ADCC) of Hodgkin lymphoma targets via ARF6/PLD-1.

CD123 (IL-3Rα) is frequently expressed by malignant Hodgkin lymphoma (HL) cells. Naked monoclonal antibodies (mAb) against HL lack clinical benefit, partially due to absence of natural killer (NK) cells in the tumor microenvironment. Here we show that the combination of a fully humanized anti-CD123 mAb (CSL362) and high-affinity Fcγ-receptor NK-92 cells (haNK) effectively target and kill HL cells in vitro.

Enhanced human hematopoietic stem and progenitor cell engraftment by blocking donor T cell-mediated TNFα signaling.

Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative therapy, but the large number of HSCs required limits its widespread use. Host conditioning and donor cell composition are known to affect HSCT outcomes. However, the specific role that the posttransplantation signaling environment plays in donor HSC fate is poorly understood.

Associations between the codon 72 polymorphism of the TP53 gene and the risk of recurrent implantation failure.

Aim: Recurrent implantation failure (RIF) is the most common cause of unsuccessful pregnancy after assisted reproductive techniques. The tumor protein P53 (TP53) codon 72 polymorphism (G-C transversion) has been explored in susceptibility to RIF, but inconclusive results have been reported. The aim of this article is to estimate the associations between the TP53 codon 72 polymorphism and the risk of RIF.

The codon 72 polymorphism of the TP53 gene and endometriosis risk: a meta-analysis.

Endometriosis is a chronic, inflammatory and common gynaecological disease. This study investigated the association between TP53 codon 72 polymorphism and the risk of endometriosis. A search for relevant articles was conducted in PubMed, Embase, CNKI, Wanfang, Weipu databases and Google Scholar.

Humanized Chronic Graft-versus-Host Disease in NOD-SCID il2rγ-/- (NSG) Mice with G-CSF-Mobilized Peripheral Blood Mononuclear Cells following Cyclophosphamide and Total Body Irradiation.

Chronic graft-versus-host disease (cGvHD) is the major source of late phase morbidity and mortality after allogeneic hematopoietic stem cell transplantation. Humanized acute GvHD (aGvHD) in vivo models using NOD-SCID il2rγ-/- (NSG) mice are well described and are important tools for investigating pathogenicity of human cells in vivo. However, there have been only few reported humanized cGvHD mouse models.

[Comparision of intracellular localization and recycling route of mouse nepmucin and CD31 in endothelial cells].

Aim: To compare the localization and recycling between nepmucin and CD31 molecules on transfected endothelial cells, and attempted to clarify the recycling mechanisms of nepmucin in endothelial cells.

Methods: Recycling assay and internalization assay were employed to compare the localization and recycling pathway of nepmucin and CD31. The internalized and recycling nepmucin and CD31 molecules on transfected endothelial cells were double or single stained with specific fluorchrome-labeled monoclonal antibodies against nepmucin (Alexa Fluor 488-ZAQ5) and/or CD31 (Alexa Fluor 488-anti-CD31 or Alexa Fluor 594-anti-CD31), then observed under confocal microscopy.

Effect of high glucose levels on the calcification of vascular smooth muscle cells by inducing osteoblastic differentiation and intracellular calcium deposition via BMP-2/Cbfα-1 pathway.

In this paper, we investigate the effect and the possible mechanism of high glucose levels on the calcification of human aortic smooth muscle cells (HASMCs). HASMCs were divided into four groups: normal glucose group (NG), osmolality control group (OC), high glucose group (HG, HASMCs culture medium containing 30 mmol/L glucose), and high glucose plus recombinant human Noggin protein (bone morphogenetic protein-2 (BMP-2) antagonist) group (HN). The mRNA levels and the protein expressions of BMP-2 and core binding factor alpha-1 (Cbfα-1) were measured by real-time quantitative polymerase chain reaction (PCR) and Western blot.
