■ Q&A

I am interested in this product CSB-YP004954HU. Currently this product is supplier in a Tris buffer with 50% glycerol. Is it possible to purchase this product in PBS only?

Thanks for your inquiry, we could use PBS as storage buffer. Please kindly remark this requirement when sending your PO. We need to tell you in advance that we're not sure whether this protein can mantain stable in this buffer. If this protein is unstable in PBS, we will use the default buffer (Tris buffer with 50% glycerol) to deliver this protein.

Target Background

Function (From Uniprot)	Cytokine which is the ligand for CD27. The CD70-CD27 pathway plays an important role in the generation and maintenance of T cell immunity, in particular during antiviral responses. Upon CD27 binding, induces the proliferation of costimulated T-cells and enhances the generation of cytolytic T-cells.
Gene References into Functions	This dose-escalation phase I trial provides evidence of good tolerability of ARGX-110, pharmacokinetics, and preliminary antitumor activity at all dose levels in generally heavily pretreated patients with advanced CD70-positive malignancies PMID: 28765328 Results show that CD70 promoter region methylation and expression are regulated by MBD4. Indeed, the study shows that downregulation of MBD4 contributed to overexpression and hypomethylation of the CD70 gene in CD4+ T cells from patients from systemic lupus erythematosus. PMID: 29018507 CD70 mitigates atherosclerosis at least in part by modulating macrophage function. PMID: 27786334 This study demonstrated that Expression of CD70 (CD27L) Is Associated With Epithelioid and Sarcomatous Features in IDH-Wild-Type Glioblastoma. PMID: 28789475 CD27 is engaged by CD70 cross-presented by other AML blasts or stem/progenitor cells in a paracrine manner. PMID: 28031480 human CD70-CD27 interactions therefore play a nonredundant role in T and B cell-mediated immunity, especially for protection against EBV and humoral immunity. PMID: 28011864 These data demonstrate the important role of the CD70/CD27 axis in immune responses in HTLV-1 carriers and ATL patients. PMID: 26077361 CD70: An emerging target in cancer immunotherapy PMID: 26213107 Both monomeric and trimeric forms of CD70 were detected in tumour cell membrane fractions, whereas cytoplasmic fractions contained almost exclusively monomeric CD70 PMID: 26671750 CD70 is overexpressed in systemic lupus erythematosus CD4+ T cells, but expression is not linked to the typical clinical and serological parameters associated with the disease. PMID: 24238281 CD70-blocking of alphaDC1s from both controls and patients with chronic lymphocytic leukaemia had a negative influence on the production of both IL-12p70 and the Th1 cytokine IFN-gamma. PMID: 24684541 CD70 acts as a functional receptor binding to soluble CD27, resulting in lymphoma progression and that immunotherapy using anti-CD70 antibody may be a potential candidate for treatment for NNKTL. PMID: 23206232 The mean expression of CD70 was almost twice as high in renal cell carcinoma relative to normal kidney tissue PMID: 22401771 Regulation of Langerhans cell CD70 expression is important in enhancing immunity against cutaneous epithelial pathogens and cancer. PMID: 22377764 Findings suggest that demethylation of CD70 promoter region contributes to the overexpression of CD70 in CD4+ T cells and may contribute to autoimmune response in systemic sclerosis (SSc). PMID: 22306512 These findings indicate that aberrant histone modifications within the TNFSF7 promoter may contribute to the development of lupus by increasing CD70 expression in CD4(+) T cells. PMID: 21865261 CD70 and CD11a facilitate the survival of T and B lymphocytes and indirectly enhance the destruction of platelets in immune thrombocytopenia. PMID: 21541792 data indicate that the virus-induced selective upregulation of CD70 by Langerhans cells is the critical feature that enhances their capacity to induce effector CD8+ T cell responses compared with virus-primed dermal dendritic cells that lack CD70 PMID: 21880979 concluded DNA methyltransferases(DNMTs) functioned as demethylases as MBD2, while increased DNMTs and MBD2 may cause demethylation and over expression of CD70 in CD4(+) T cells, potentially contributing to the pathogenesis of immune thrombocytopenia PMID: 21550117 Th1 cell-specific CD70 expression may be involved in an amplification loop for polarized Th1-type immune responses through T cell-T cell interactions. PMID: 21490618 Stimulation of T cells expressing CD70-specific chimeric antigen receptors resulted in CD27 costimulation and recognition of CD70-positive tumor cell lines and primary tumor cells, as shown by IFN-gamma and IL-2 secretion and by tumor cell killing. PMID: 21304103 RFX1 recruits SUV39H1 to the promoter regions of the CD11a and CD70 genes in CD4(+) T cells, thereby regulating local H3K9 tri-methylation levels. PMID: 21192791 In this review, CD27 and CD70 constitute a unique pair ligand and receptor pair which can activate innate and adaptive immunity as well as regulate immunity versus tolerance. PMID: 20699361 CD70 expression was significantly elevated and correlated with a decrease in CD70 promoter methylation in T4 lymphocytes from Sjogren's syndrome patients as compared to levels in controls. PMID: 20724115 Epigenetic silencing of the TNFSF7 gene via hypermethylation of its proximal region may allow the benign and invasive MCF10 variants to escape immune surveillance. PMID: 20119871 the CD70-CD27 interaction may play an important role in inducing effective immune responses in dendritic cell-based immunotherapy. PMID: 20201989 CD70 is an important factor in the regulation of B-cell growth and differentiation by plasmacytoid dendritic cells. PMID: 20139096 Data confirm previous observations of higher expression of CD70 in CD4+ T cells from patients with SLE, and suggest that increased Fyn protein content in CD4+ T cells can be associated with high SLE disease activity. PMID: 19955046 Identification of CD70-mediated apoptosis of immune effector cells as a novel immune escape pathway of human glioblastoma PMID: 11980654 intragraft gene expression is not a risk factor for acute cardiac allograft rejection PMID: 12009595 Systemic lupus erythematosus T cells and T cells treated with DNA methyltransferase inhibitors and ERK pathway inhibitors overexpress CD70. PMID: 15188362 Immunocytochemical analysis demonstrated that binding of an anti-CD70 antibody to CD70(TNFSF7), endogenously expressed on the surface of A498 and 786-O cell lines resulted in the rapid internalisation of the antibody-receptor complex. PMID: 16892042 Apoptosis mediated by exposure to the CD70 secreted by tumor cells may contribute to the failure of renal cell carcinoma patients to develop an effective lymphocyte-mediated antitumor response PMID: 17132225 reveal a novel role for non-Hodgkin lymphoma B cells in the development of intratumoral regulatory T cells PMID: 17615291 CD27-CD70 interactions in the pathogenesis of Waldenstrom macroglobulinemia. PMID: 18216294 CD70 gene was upregulated more than 1,000-fold and the enhanced expression of the CD70 molecule was confirmed by laser flow cytometry for various HTLV-1-carrying T-cell lines and primary CD4(+) T cells isolated from acute-type ATL patients. PMID: 18256142 Dendritic cells matured in the presence of PGE(2) induced the expression of OX40, OX40L, and CD70 on T cells facilitating T-cell/T-cell interaction that warrant long-lasting costimulation. PMID: 19029446 CD70 not only contributes to the activation of cytotoxic T cells in B cell precursor acute lymphoblastic leukemia but is a critical signal during the expansion phase of the cytotoxic T cell response. PMID: 19109206 Constitutive expression of CD70 transgene is sufficient to deregulate the CD8 T cell differentiation pathway of acute infection reminiscent of events in chronic infection. PMID: 19380782 Data showed that the CD70, perforin and KIR2DL4 promoters are demethylated in CD4(+)CD28(-) T cells, and that DNA methyltransferase 1 (Dnmt1) and Dnmt3a levels are decreased in this subset.
