Application Notes: This antibody is specific for murine CD27, and has been used to assess the distribution of CD27 expression using IF, FC and IP analysis (Gravstein, 1995). Upon cross-linking, this antibody has been shown to induce a 4-fold increase in T cell proliferation in response to suboptimal stimulation with concanavalin A (Gravestein, 1995), indicating that this antibody is able to mimic ligand binding. Antibody First Published in: Gravstein et al. Novel mAbs reveal potent co-stimulatory activity of murine CD27 International immunology, April 1995, Vol.7(4), pp.551-7 PMID:7547681 Note on publication: Describes the original use of this antibody to elucidate the distribution and co- stimulatory activity of CD27.

  • CD40L TNF-Related Factors BAFF, APRIL, and Lymphocytic Leukemia
    Published May 16, 2012, doi:10.4049/jimmunol.1102066 The Journal of Immunology Stromal Endothelial Cells Establish a Bidirectional Crosstalk with Chronic Lymphocytic Leukemia Cells through the TNF-Related Factors BAFF, APRIL, and CD40L Montserrat Cols,* Carolina M. Barra,† Bing He,* Irene Puga,† Weifeng Xu,* April Chiu,‡ Wayne Tam,x Daniel M. Knowles,x Stacey R. Dillon,{ John P. Leonard,‖ Richard R. Furman,‖ Kang Chen,* and Andrea Cerutti*,†,# Chronic lymphocytic leukemia (CLL) is a clonal B cell disorder of unknown origin. Accessory signals from the microenvironment are critical for the survival, expansion, and progression of malignant B cells. We found that the CLL stroma included microvascular endothelial cells (MVECs) expressing BAFF and APRIL, two TNF family members related to the T cell-associated B cell-stimulating molecule CD40L. Constitutive release of soluble BAFF and APRIL increased upon engagement of CD40 on MVECs by CD40L aberrantly expressed on CLL cells. In addition to enhancing MVEC expression of CD40, leukemic CD40L induced cleavases that elicited intracellular processing of pro-BAFF and pro-APRIL proteins in MVECs. The resulting soluble BAFF and APRIL proteins delivered survival, activation, Ig gene remodeling, and differentiation signals by stimulating CLL cells through TACI, BAFF-R, and BCMA receptors. BAFF and APRIL further amplified CLL cell survival by upregulating the expression of leukemic CD40L. Inhibition of TACI, BCMA, and BAFF-R expression on CLL cells; abrogation of CD40 expression in MVECs; or suppression of BAFF and APRIL cleavases in MVECs reduced the survival and diversification of malignant B cells. These data indicate that BAFF, APRIL, and CD40L form a CLL-enhancing bidirectional signaling network linking neoplastic B cells with the microvascular stroma.

EMT can be induced by soluble proteins like transforming growth factor β1 (TGFβ1) and transcription factors including Snail and Slug. We uti- lized the ARCaPE/ARCaPM prostate cancer progression model and LNCaP clones stably overexpressing Snail to identify novel markers associated with EMT. Compared to ARCaPE cells, the highly tumorigenic mesenchymal ARCaPM and ARCaPM1 variant cells displayed a higher incidence of bone metastasis after intracardiac administration in SCID mice. ARCaPM and ARCaPM1 expressed mesenchymal stromal markers of vimentin and N-cadherin in addition to elevated levels of Receptor Activator of NF-κB Ligand (RANKL). We observed that both epidermal growth factor (EGF) plus TGFβ1 treatment and Snail overexpression induced EMT in ARCaPE and LNCaP cells, and EMT was associated with increased expression of RANKL protein.

    Clinical Roundtable Monograph Clinical Advances in Hematology & Oncology April 2014 CD30 in Lymphoma: Its Role in Biology, Diagnostic Testing, and Targeted Therapy Discussants Eduardo M. Sotomayor, MD Susan and John Sykes Endowed Chair in Hematologic Malignancies Moffitt Cancer Center Scientific Director, DeBartolo Family Personalized Medicine Institute Professor, Department of Oncologic Sciences and Pathology & Cell Biology University of South Florida College of Medicine Tampa, Florida Ken H. Young, MD, PhD Associate Professor The University of Texas MD Anderson Cancer Center Department of Hematopathology Houston, Texas Anas Younes, MD Chief of Lymphoma Service Memorial Sloan Kettering Cancer Center New York, New York Abstract: CD30, a member of the tumor necrosis factor receptor superfamily, is a transmembrane glycoprotein receptor consisting of an extracellular domain, a transmembrane domain, and an intracellular domain. CD30 has emerged as an important molecule in the field of targeted therapy because its expression is generally restricted to specific disease types and states. The major cancers with elevated CD30 expression include Hodgkin lymphoma and anaplastic large T-cell lymphoma, and CD30 expression is considered essential to the differential diagnosis of these malignancies. Most commonly, CD30 expression is detected and performed by immunohistochemical staining of biopsy samples. Alternatively, flow cytometry analysis has also been developed for fresh tissue and cell aspiration specimens, including peripheral blood and bone marrow aspirate. Over the past several years, several therapeutic agents were developed to target CD30, with varying success in clinical trials. A major advance in the targeting of CD30 was seen with the development of the antibody-drug conjugate brentuximab vedotin, which consists of the naked anti-CD30 antibody SGN-30 conjugated to the synthetic antitubulin agent monomethyl auristatin E.
