In a previous study, CD137-expressing T cells were targeted for selective depletion of alloreactive T cells from antileukemic and antitumor donor T cell lines. 2 The CD137 MicroBead Kit was developed for positive selection of CD137

CD137 (4–1BB) was originally identified as a molecule expressed on activated mouse and human CD8 + and CD4 + T cells. 7, –9 It is a member of the TNFR family and mediates costimulatory and antiapoptotic functions, promoting T-cell proliferation and T-cell survival. 10,11 CD137 has been reported to be up-regulated—depending on the T-cell stimulus—from 12 hours to up to 5 days after

•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. Activation-induced expression of CD137 permits detection, isolation, and cell (VSMC) content, and increased macrophage inﬁl-tration. CD137 also increases the inﬁltration of effector T(T eff) cells into plaque lesion sites, resulting in increased interferon- (IFN-) expression. Interest-ingly, T eff-cell-derived IFN- inhibits collagen synthesis in atherosclerotic plaques.

1, 2 CD137 receptor delivers potent costimulatory signals to activated T lymphocytes maintaining cell division, facilitating differentiation into effector and memory cells and acting as an important survival factor. 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.

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.

CD137 is expressed by activated T cells of both the CD4+ and CD8+ lineages. Although it is thought to function mainly in co-stimulating those cell types to support their activation by antigen presenting cells expressing its ligand (CD137L), CD137 is also expressed on dendritic cells, B cells, NK cells, neutrophils and macrophages. 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.

Interaction of CD137 with its ligand (CD137L, also known as TNFSF9 or 4-1BBL) on activated antigen-presenting cells (APCs) could lead to bidirectional activation that promotes immunity against cancer [ 3 ]. An higher percentage of CD137 + T-cells in peripheral blood of patients at baseline resulted also as an important independent prognostic factor for a better OS (p = 0.0027, Kaplan–Meier method and log-rank tests) after the anti-PD-1 treatment, with a sharply better median OS for patients that had more than 0.65% of CD137 + T-cells (460 days T cells ¾ T cell lines expanded with Dynabeads® Human T-Activato r CD3/CD28/CD137 express markers associated with central memory phenotype Background.

Here we provide evidence that CD137 is selectively expressed on the surface of tumor endothelial cells. Hypoxia upregulated CD137 on Dynabeads Human T-Activator are coupled with anti-CD3, anti-CD28, and anti-CD137 antibodies.

These cells will be grown and frozen. To make the T cells, investigators will take blood (or blood from a donor) and stimulate it with growth factors to make the T cells grow. To get the CD19 antibody and CD28 (with or without CD137) to attach to the surface of the T cell, they will insert the antibody gene into the T cell.

The CD137 receptor (4-1BB, TNF RSF9) is an activation induced molecule expressed by antigen-specific T-cells. The engagement with its ligand, CD137L, is capable of increasing T-cell survival, proliferation, and cytokine production. This allowed to identify the CD137+ T-cells as the real tumor-specific activated T-cell population. In fact, these cells express various TCRs that are specific for CD137 (4-1BB, TNF-receptor superfamily 9) is a surface glycoprotein of the TNFR family which can be induced on a variety of leukocyte subsets.
