Background

The 9D9 antibody blocks the mouse cytotoxic T lymphocyte antigen-4 (CTLA-4). Blocking CTLA-4 removes an inhibitory signal from reducing the activity of T lymphocytes.
Cytotoxic T-lymphocyte antigen-4 (CTLA-4) is an inhibitory molecule that competes with the stimulatory CD28 for binding to B7 on antigen presenting cells. CTLA-4 and CD28 are both presented on the surface of T-cells.

Simpson TR, et al. J Exp Med. 2013 Aug 26;210(9):1695-710. doi: 10.1084/jem.20130091. PMID: 23878181
The study investigates the mechanism of anti-CTLA-4 therapy using the 9D9 monoclonal antibody in a B16 melanoma mouse model. Tumor-infiltrating lymphocytes were isolated from B16 tumors 7 days after the final dose of anti-CTLA-4 mAb and stained with fluorescently conjugated antibodies against CD4, CD25, CTLA-4 (clone 9D9), FoxP3, CD103, CD8, and CD45.1. Flow cytometry, performed on a modified FACSCanto II cytometer and analyzed with FlowJo software, showed that Tregs were gated as CD4+ FoxP3+ tumor-infiltrating lymphocytes, with the frequency of CTLA-4+ Tregs determined. Anti-CTLA-4 therapy significantly increased CD8+ T cell infiltration in tumors, highlighting the Fc-dependent depletion of regulatory T cells as a key factor in therapeutic efficacy.

This study explores the effects of anti-CTLA-4 therapy using the 9D9 monoclonal antibody on melanoma-reactive CD4+ T cells. Splenocytes were harvested and stained with fluorescently conjugated antibodies against CD4, CD8, CD25, CD44, CTLA-4 (clone 9D9), and PD-1 for flow cytometry analysis. Tetramer staining identified melanoma-specific CD4+ T cells, revealing a 3-fold increase in their frequency following anti-CTLA-4 treatment. Polyfunctional cytokine production was assessed via intracellular staining, demonstrating that anti-CTLA-4 therapy enhances the melanoma-reactive CD4+ T cell response.

This study examines CTLA-4 expression on activated T cells using the 9D9 monoclonal antibody. Activated T cells were stained with PE-conjugated anti-mouse CTLA-4 (clone 9D9), revealing rapid upregulation of CTLA-4 within 24 hours of activation via flow cytometry. CD4+ T cells from OT-II mice were stimulated with OVA peptide, showing CTLA-4 internalization post-stimulation. Blockade with anti-CTLA-4 enhanced T cell expansion, demonstrating the role of CTLA-4 in regulating T cell responses in animal models.
