CD137, also known as 4-1BB, is a member of the TNFR super family. CD137 is closely related to CD27, OX40, and CD30. It is up-regulated on mouse and human T cells upon activation. 2 It has long been recognized as a costimulatory molecule for T cells. Expansion of the T cell population can be stimulated using recombinant IL-2, and after activation or expansion, the magnetic beads can be easily removed using a DynaMag™ magnet. For expansion of antigen-specific T cells from T cell clones or T cell lines, we recommend using Dynabeads® Human T-Activator CD3/CD28/CD137.

2 It has long been recognized as a costimulatory molecule for T cells. As CD137 up-regulation is a function of T-cell activation, the threshold for inducing CD137 expression was compared with IFNγ and TNFα production after stimulation with titrated amounts of the cognate antigen. •CD137 (4-1BB/TNFRSF9) is a costimulatory receptor belonging to the TNF receptor superfamily. •CD137 agonism is a promising immunotherapeutic approach as indicated by anti-tumour effects in mouse models with agonistic monoclonal antibody therapy (1). 150 adoptive transfer of congenically marked WT or CD137-deficient CD8 T cells specific for non-151 plaque antigen.

3, 4, 5 In addition T cells following antigen stimulation and priming of naïve T cells.19–21 In vivo, CD134 co-stimulation is thought to have a more prominent role in CD4+ T-cell function, whereas CD137 preferentially co-stimulates CD8+ T cells.22 However, in vitro data indicate that CD137 can contribute to CD4+ T cell CD137 expression on CD8 + CD25 + T cells and suppressive function of CD8 + CD25 + CD137 + Tregs was measured using flow cytometry.

Cytokine levels were analyzed by ELISA. Inducible nitric oxide synthase production by nasal epithelial cells after co‐culturing with CD8 + CD25 + CD137 + T cells was analyzed by Western blotting. FACS analysis initially revealed that CD137 was expressed on T cells in the aortas of ApoE ‐/‐ mice (Fig.

Therefore, CD137 can be a useful biomarker and an important tool for the selection of tumor-reactive T cells.

CD137 + T-cells are largely known to be the anti-tumor activated effector cells, but they have never been associated with the response to immunotherapies. Methods. Forty-two patients with metastatic NSCLC receiving anti-PD-1 ICIs at Sant'Andrea Hospital and Policlinico Umberto I, from June 2016 to September 2018 were enrolled. 2019-11-08 2016-01-01 CD137, a member of the TNF receptor family, and its ligand are expressed on T lymphocytes and antigen‐presenting cells (APC), respectively.

T-cells from antileukemic and antitumor donor T-cell lines using the anti-CD137 magnetic cell separation sys-tem. In this study, we developed a method to selectively eliminate alloreactive CD4+ and CD8+ T-cells through CD137-mediated internalization of anti-CD137 mAbs con-jugated with the ribosome-inactivating protein saporin. The T cells cocultured with DC 2.4 cells that were pretreated with A20‐CD137 cells were less activated than the control T cells, as evidenced by the lower secretion of IFN‐γ after 24 h . These data demonstrate that the transfer of CD137 to CD137L‐expressing cells impairs their costimulatory activity.

Inducible nitric oxide synthase production by nasal epithelial cells after co‐culturing with CD8 + CD25 + CD137 + T cells was analyzed by Western blotting. FACS analysis initially revealed that CD137 was expressed on T cells in the aortas of ApoE ‐/‐ mice (Fig. 3A). It is well known that activated T cells produce IFN‐γ, a major proinflammatory cytokine that activates macrophages and vascular cells, and facilitates inflammation in atherosclerotic plaques.

It delivers potent costimulatory signals to T-cells that enhance cytokine secretion, proliferation, and survival. CD137, also known as 4-1BB, is a member of the TNFR super family.

2020-10-20 Activation of the CD137 Pathway in T cells by a CD137 x 5T4 bispecific ADAPTIR™ Molecule Requires Co-engagement of CD137 and 5T4. A) CD137 (NF-kB/luciferase) reporter cells were stimulated with serial dilutions of ALG.APV-527 in the presence of 5T4 or empty vector transfected CHO-K1 cells for 5 hr. ALG.APV-527 induces CD137 CD3 (cluster of differentiation 3) is a protein complex and T cell co-receptor that is involved in activating both the cytotoxic T cell (CD8+ naive T cells) and T helper cells (CD4+ naive T cells). It is composed of four distinct chains. In mammals, the complex contains a CD3γ chain, a CD3δ chain, and two CD3ε chains. These chains associate with the T-cell receptor (TCR) and the ζ-chain CD137/CD137 ligand (L), members of tumor necrosis factor (TNF) receptor/ligand families, regulate cell activation and proliferation of immune system.
