Description

Background of Recombinant Anti-Mouse CD137 (4-1BB) Monoclonal Antibody (Clone: 3H3)

The 3H3 antibody binds to 4-1BB (TNFRSF9 or CD137), one representative TNF receptor family co-stimulatory receptor. The 4-1BB protein is expressed on a wide variety of cell types, including activated T cells, NK cells, DCs, B cells, monocytes, and neutrophils. Anti-4-1BB-induced CD8+ T responses play a dominant role in anti-tumor immunity, such as induction of more effector molecules released from CD8+ T cells, increased proliferation and decreased apoptosis of CD8+ T cells.

The co-stimulatory receptor 4-1BB (CD137) is a major target for cancer immunotherapy due to its ability to enhance T cell-mediated anti-tumor responses. ... Here, we demonstrate that optimizing the balance between agonistic strength and Fc?R binding affinity is critical to maximizing therapeutic efficacy. ... These findings suggest a design strategy for developing safer and more effective anti-4-1BB antibodies, like clone 3H3, with minimized systemic toxicities.

In this study, we investigated the potential of co-stimulatory agonists targeting 4-1BB and OX40 to enhance vaccine-induced T-cell immunity. ... We show that administration of agonistic anti-4-1BB (clone 3H3) and anti-OX40 antibodies during vaccination dramatically increases both CD4+ and CD8+ T-cell responses. ... These results highlight the synergistic potential of combining co-stimulatory pathway activation with viral vector-based vaccine regimens to achieve robust protective immunity.

Bispecific antibodies targeting both tumor antigens and co-stimulatory receptors represent a promising class of cancer immunotherapeutics. ... We designed mRNA-encoded bispecific molecules that facilitate polyclonal T cell engagement alongside PD-L1-dependent 4-1BB (CD137) costimulation. ... This approach restricts 4-1BB activation to the tumor microenvironment, mimicking the localized efficacy of clones like 3H3 while eliminating systemic safety liabilities.

CD137 (4-1BB) is typically considered a co-stimulatory molecule that acts in concert with T-cell receptor (TCR) activation. ... We demonstrate that TCR-independent CD137 signaling can directly drive the proliferation and terminal differentiation of exhausted CD8+ T cells in chronic viral or tumor settings. ... These results reveal a novel role for CD137 agonists, such as the 3H3 clone, in reviving exhausted T-cell populations independently of antigen recognition.

Agonistic antibodies targeting CD137 (4-1BB) have shown powerful antitumor effects in preclinical models, but clinical development has been hindered by severe liver toxicity. ... Here, we present a differentiated agonistic antibody that achieves robust antitumor efficacy and eradicates large established tumors. ... Crucially, this therapeutic approach avoids systemic hepatotoxicity, establishing a wider therapeutic window for clinical applications of CD137-targeting agents.
