Heterogeneity and Homogeneity in Treg responses to Interleukin-2 [RNAseq2: Differential activation of Immune cell types by IL2-Immunocytokines]

ABSTRACT: IL2 is an immune-regulatory cytokine that activates both effector and T regulatory cells—a dual function leveraged in immunotherapy. However, pure IL2 induces both activation and suppression, and requires toxic doses due to its short half-life. To address this, the Spangler Lab at Johns Hopkins developed IL2 immunocytokines (IL2-ICs)—antibody-conjugated IL2 fusion proteins targeting IL2Ra (Tregs) or IL2Rb (effector cells), with extended serum half-life. We tested IL2-ICs in Foxp3IRES-GFP mice, harvesting cells at 4, 24, and 64 hours post-injection for bulk RNA-seq. Transcriptomic analysis showed IL2-ICs induced sustained IL2 responses with partial cell-type bias.

Anti-GD2 antibodies conjugated to IL15 and IL21 mediate potent anti-tumor cytotoxicity against neuroblastoma

Project description:Half of the patients with high-risk neuroblastoma (NB) who receive GD2-targeted monoclonal antibody do not achieve long-term remissions. Recently, the antibody hu14.18 has been linked to interleukin (IL)2 (hu14.18-IL2) to enhance its efficacy and shown promising preclinical and clinical activity. We developed two new immunocytokines (ICs) by linking two other γc cytokines, IL15 and IL21, to hu14.18. The purpose of this study was to compare hu14.18-IL15 and -IL21 to hu14.18-IL2 in their ability to induce antibody-dependent cell-mediated cytotoxicity (ADCC) against NB. We assessed ADCC of hu14.18-IL15 and -IL2 (human cytokines, cross-reactive to mouse) against GD2low and GD2high NB cell lines in vitro. T-cell deficient mice with orthotopic patient-derived xenografts (PDXs) and immunocompetent mice with transplantable orthotopic NB were used to test all three ICs, including hu14.18-IL21 (murine IL21, not cross-reactive to human). Mechanistic studies were performed using single-cell RNA-sequencing (scRNA-seq). Hu14.18-IL15 and hu14.18-IL2 mediated equivalent in vitro ADCC by human NK cells. When combined with chemotherapy, all three ICs similarly controlled the growth of PDXs in nude mice with murine NK effector cells. However, hu14.18-IL15 and -IL21 outperformed hu14.18-IL2 in immunocompetent mice with syngeneic NB, inducing complete tumor regressions and extending survival. scRNA-seq data revealed an increase in CD8+ T cells and M1 tumor-associated macrophages and decreased regulatory T cells and myeloid-derived suppressor cells in the tumor microenvironment. Hu14.18-IL15 and Hu14.18-IL21 exhibit robust preclinical activity, warranting further consideration for clinical testing in patients with GD2-expressing NB.

Heterogeneity and Homogeneity in Treg responses to Interleukin-2 [scATAC-seq2: IL2/JES6-1 timecourse]

Project description:We investigated the dynamic effects of IL2 exposure on Treg chromatin accessibility over time by performing scATAC-seq on splenic Tregs isolated from mice at mulitple timepoints (1,2,4,8,16,32,64,128hours) after treatment with IL2/JES6-1 complexes or PBS vehicle control.

Heterogeneity and Homogeneity in Treg responses to Interleukin-2 [scRNA-seq: IL2/JES6-1 timecourse]

Project description:Interleukin-2 (IL2) is the key trophic factor for T Regulatory (Treg) cells, regulating both their differentiation and homeostasis. To understand how temporally regulated responses to IL2 unfold in Tregs, we performed fine time-course analyses at single-cell level induced by IL2 in Tregs in vivo. The data revealed responses that were largely uniform in resting Treg, but diverse among activated or effector Tregs, matching different STAT5 signal transduction efficiency. Individual Tregs displayed divergences in the preponderance of changes downstream of STAT1 or STAT5.

resting and IL2 activated human natural killer cells

Project description:The aim of the study was to investigate the activation of human NK cells by IL2 through analyzing the global gene expression at different time points (0, 2, 8 and 24 hours) after culture with the cytokine IL2 at 100 IU/ml. NK cells with the CD56+/CD16+ and CD3- phenotype were negatively selected by immunomagnetic beads and re-examined by flow-cytometry to ensure greater than 90% purity . Keywords: resting and IL2 activated NK cells(time series)
