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.
4-1BB ligand (4-1BBL) is an inducible molecule present on several APC types, including B cells, macrophages and DCs (Pollock et al., 1994; DeBenedette et al., 1997). The CD137 receptor (4-1BB, TNFRSF9) is a member of the tumor necrosis factor receptors (TNFR) family and was characterized as an inducible costimulatory receptor on T-cells, together with its ligand (CD137L, 4-1BBL), both in human and mice [ 14 ]. 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.

2017-06-24 · CD137 can maintain the response signal of T cells, which plays a key role in the survival of T cells and the memory of CD8 + T cells [19,20,21]. The scFvCD19-CD137-CD3-CAR-T cells, MOv19-BBζ-CAR-T cells and scFvCD19-CD28-CD3ζ-CAR-T cells were used to treat B cell malignancies, and achieved better outcomes than the first generation [ 22 , 23 ].
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.
CD137, a member of the TNF receptor family, and its ligand are expressed on T lymphocytes and antigen‐presenting cells (APC), respectively. During interaction with APC, T lymphocytes receive a potent, costimulatory signal through CD137. Reverse signaling has been demonstrated for the CD137 ligand, which causes activation in monocytes.
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.

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.

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.
Dec 16, 2015 The work focuses on agonist therapy for CD137, which is a regulator of T cell activation, proliferation, and cytokine production. Studies for this
•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. Furthermore, CD137 activa- 2020-10-20 · CD137 was predominantly expressed in CD8+ T cells in GCs and had a positive correlation with tumor cell differentiation.
4-1BB (CD137) is a member of the TNFR family and is rapidly expressed on activated CD8+ T cells and also on activated CD4 + T cells with lower levels. Its ligand, 4-1BBL, is a TNF family member and expressed on APCs such as mature DCs, activated B cells, 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. 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.
