CD137 (TNFSFR9) was originally identified as a molecule induced on the surface of activated mouse and human CD4+ and CD8+ T cells, with its expression undetectable on non-activated T cells. It is also found on both NK and dendritic cells. Ligation of the receptor induces T cell proliferation and IL-2 production as well as inhibiting apoptosis. CD137, also called 4-1BB, is a member of the TNF receptor superfamily with T-cell costimulatory functions (5). Signaling through CD137 by its natural ligand, CD137L, or agonistic antibody promotes the expansion of T cells, sustains their survival, and enhances their cytolytic effector functions. Enriched CD137(pos) TILs, but not PD-1(pos) or PD-1(neg) CD137(neg) cells, possessed autologous tumor reactivity in vitro and in vivo. Although CD4(+) T cells are efficiently activated through the T cell receptor and CD137 receptor, it provokes CD4(+) T cell anergy and blockade of T-dependent humoral immune responses.

2016-01-01 · CD137 signaling enhanced the production of proinflammatory cytokines and cytotoxic molecules in tumor-specific CD4(+) T cells. Interestingly, a subset of CD4(+)Foxp3(+) regulatory T cells was reprogrammed to eliminate immunogenic virus-induced tumor cells in response to CD137 agonist treatment. 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 .

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 Costimulatory T-cell engagement by PRS-343, a CD137 (4-1BB)/HER2 bispecific, leads to tumor growth inhibition and TIL expansion in humanized mouse model [abstract].

We further compared the phenotype and function of CD137 + and CD137 CD137 (4-1BB) has been identified as a co-stimulatory marker, which is induced upon the specific interaction of T cells with their target cell. Therefore, CD137 can be a useful biomarker and an important tool for the selection of tumor-reactive T cells. Here, we developed and validated a simple and time efficient method for the selection of T cells expressing CD28 and CD137 domain-containing CARs pro-duced greater quantities of IL-2 when compared with cells express-ing the αCD19-ζ receptor (Figure 3). The production of the type 2 cytokines, IL-4 and IL-10, by CD4+ T cells was also stimulated by All You are here.

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 and the ζ-chain to generate an activation signal in T lymphocytes. The TCR, ζ-chain, and CD3 molecules together constitute the TCR complex. •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). If you are working with human T cells, in my experience CD137 works best, you can check the following report.

It is also found on both NK and dendritic cells. Ligation of the receptor induces T cell proliferation and IL-2 production as well as inhibiting apoptosis. 4-1BB (CD137) is an activation-induced costimulatory molecule that is expressed on activated T cells, NK cells, dendritic cells, eosinophils, mast cells, endothelial cells, and some tumor cells.
