1. Two novel human anti-CD25 antibodies with antitumor activity inversely related to their affinity and in vitro activity
Deyong Song,et al.Sci Rep. 2021.PMCID: PMC8617198
“High tumor regulatory T (Treg) cell infiltration is associated with poor prognosis of many cancers. CD25 is highly expressed on tumor Treg cells and is a potential target for Treg deletion. Previously characterized anti-CD25 antibodies appear to have limited efficacy in tumor inhibition. Here we identified two human anti-CD25 antibodies, BA9 and BT942, which did not prevent the activation of IL-2R signaling pathway by IL-2. BT942 had weaker binding and cytotoxic activity to human CD25-expressing cell lines than BA9. But both demonstrated significant tumor growth inhibition in early and late-stage animal cancer models. BT942 resulted in a higher expansion of CD8+ T cells and CD4+ T cells in tumor microenvironment in mouse MC38 model compared to BA9. BT942 also demonstrated significant higher tumor growth inhibition and higher expansion of CD8+ T cells and CD4+ T cells in combination with an anti-PD1 antibody. Pharmacokinetic study of BT942 in cynomolgus monkeys demonstrated a half-life of 206.97 ± 19.03 h. Structural analysis by cryo-EM revealed that BT942 recognizes an epitope on opposite side of the CD25-IL-2 binding site, consistent with no IL-2 signaling blockade in vitro. BT942 appears to be an excellent candidate for cancer immunotherapy.”
2. TRAIL suppresses tumor growth in mice by inducing tumor-infiltrating CD4+CD25+ Treg apoptosis
Zhijuan Diao,et al.Cancer Immunol Immunother. 2013.PMCID: PMC11028869
“Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), a promising and novel anticancer cytokine, specifically kills numerous tumor cells by apoptosis. However, some malignancies are resistant to TRAIL treatment in clinical trials, thus limiting its therapeutic potential. In the present study, the TRAIL-resistant murine hepatocellular carcinoma cell line Hepa1-6 was used to elucidate the physiological significance of TRAIL resistance, especially with respect to the immune regulatory function of TRAIL. Hepa1-6 cells were resistant to TRAIL-induced apoptosis in vitro; however, intratumoral injection of recombinant soluble TRAIL inhibited tumor growth and prolonged survival time in tumor-bearing mice. Local TRAIL treatment decreased the number of intratumoral CD4+CD25+Foxp3+ regulatory T cells (Tregs) but did not affect CD4+CD25+Foxp3+ Tregs in the draining lymph nodes and spleen. Further investigation showed that TRAIL induced apoptosis of tumor-activated CD4+CD25+Foxp3+ Tregs, but not of CD4+CD25− T cells. Moreover, mouse TRAIL receptor DR5 expression was detected on the surface of the tumor-infiltrating CD4+CD25+Foxp3+ Tregs, but not on naïve CD4+CD25+Foxp3+ Tregs. Interestingly, intratumoral injection of TRAIL not only decreased the number of CD4+CD25+Foxp3+ Tregs but also increased the number of tumor-specific CD8+ CTL and augmented their cytotoxicity to the tumor cells. These data provide the novel evidence for an immune regulatory function of TRAIL and may shed light on the clinical application of TRAIL.”
3. A distinct subpopulation of CD25− T-follicular regulatory cells localizes in the germinal centers
James Badger Wing,et al.Proc Natl Acad Sci U S A. 2017.PMCID: PMC5547636
“T-follicular regulatory (Tfr) cells, a subset of Foxp3-expressing regulatory T (Treg) cells, have a critical role in the control of antibody responses. Whereas Treg cells express CD25 and are dependent on IL-2, Tfr cells also express the transcription factor BCL6 that is inhibited by IL-2 in T-follicular helper (Tfh) cells. In this report, we find that mature Tfr cells in the germinal centers or circulating in human blood down-regulate CD25 and gain a transcriptional signature mixed between Tfh cells and Treg cells while retaining their regulatory function. These cells represent an IL-2–independent branch of effector Treg cells losing CD25 expression but gaining increased expression of Tfh-related markers, such as BCL6 and CXCR5, in both mice and humans.”

背景知识

The in vivo grade recombinant anti-mouse CD25 monoclonal antibodies（体内实验级重组抗小鼠CD25单克隆抗体） are based on the rat monoclonal antibody（大鼠单克隆抗体） anti-CD25 (mouse) with the clone number of PC61, PC61.5 or PC61.5.3. The rat IgG1 lamda monoclonal antibody（大鼠IgG1 lamda 单克隆抗体） has been validated and reported for use in immunoprecipitation (IP), immunohistochemistry (IHC), Flow Cytometry (FC), and various functional assays, such as in vivo depletion of CD25+CD4+ Treg cells, in vitro blocking of IL-2 binding to low- and high-affinity receptors, and growth inhibition of IL-2-dependent T-cell lines. Expression of CD25, together with CD4 and FOXP3, is considered a phenotypic signature for Treg cells. In vivo depletion of mouse CD25(+)CD4(+)FoxP3(+) Treg cells using the rat PC61 monoclonal antibody（大鼠PC61单克隆抗体） is widely used to characterize the Treg function. The PC61 monoclonal antibody（PC61单克隆抗体） specifically binds to an epitope of CD25 which is distinct from the IL-2 binding site and from those recognized by the 3C7 and 7D4 monoclonal antibodies. By doing so, the antibody blocks binding of IL-2 to CD25.
