Krüppel-like factor 4 regulates the cytolytic effector function of exhausted CD8 T-cells [SMART-Seq]

ABSTRACT: To identify the role of KLF4 on exhausted CD8 T-cells in vivo, we adoptively transferred PmelI CD8 T-cells transduced with MigRI/Klf4 into MC38-gp100 tumor-bearing Rag2 KO mice on day7. We then isolated tumor-infiltrating PmelI CD8 T-cells on day15 and their gene expression profiles were analyzed by SMART-seq. Also, to investigate the effect of KLF4 deficiency, we isolated PD1+ CD8+ TILs from MC38 tumor-bearing control and Klf4 cKO mice on day14, and SMART-seq was performed.

Chromatin accessibility analysis of tumor-infiltrating CD8+ T cells from tumor-bearing mice transferred Nrf2-deficient CD8+ T cells. [ATACseq]

Project description:To identify unique chromatin regions predicting the anti-tumor efficacy of Nrf2-deleted smart CD8+ T cell therapy, we performed an assay for transposase-accessible chromatin sequencing (ATAC-seq) using tumor-infiltrating CD8+ T cells from tumor-bearing mice transferred Nrf2-deficient CD8+ T cells. From the analysis of ATAC-seq data, we identified quantitatively distinct open regions of chromatin that distinguish Nrf2-deficient CD8+ T cells or WT CD8+ T cells.

Identification and validation of a tumor-infiltrating Treg transcriptional signature conserved across species and tumor types.

Project description:We reported transcriptional characterization of tumor-infiltrating T regulatory cells (TITRs) that is shared between species and among different tumor types and stages. We genomically profiled immunocytes from 2 species: 1. Mouse: CD4+ Treg and Tconv, and CD8+ T cells from tumor and spleen of B16, MC38 or CT26 tumor bearing mice, as well as from spleens of non-tumor bearing mice. 2. Human: CD4+ Treg cells from surgically resected and cryopreserved human colorectal carcinomas or normal colon tissue.

Studies in a murine B16 melanoma model show that persistent antigen at vaccination sites induces CD8+ T cell sequestration, dysfunction and deletion

Project description:To understand why cancer vaccine-induced T cells often fail to eradicate tumors, we studied immune responses in mice vaccinated with gp100 peptide emulsified in incomplete Freund's adjuvant (IFA), commonly used in clinical cancer vaccine trials. After gp100 peptide/IFA vaccination, tumor-specific CD8+ T cells (adoptively transferred from gp100-specific TCR-transgenic pmel-1 mice) accumulated not in tumors but at the persisting, antigen-rich vaccination site. Once there, primed T cells became dysfunctional and underwent antigen-driven, IFN-γ and FasL-mediated apoptosis, resulting in systemic hyporesponsiveness to subsequent vaccination. Provision of anti-CD40 antibody, TLR7 agonist and interleukin-2 (covax) reduced T cell apoptosis but did not prevent vaccination site sequestration. A non-persisting vaccine formulation shifted T cell localization towards tumors, inducing superior anti-tumor activity. Short-lived formulation also reduced systemic T cell dysfunction and promoted memory formation, as shown by gene expression profiling and other measures. Persisting peptide/IFA vaccine depots, currently used to vaccinate cancer patients, can induce specific T cell sequestration at vaccination sites followed by dysfunction and deletion; short-lived depot formulations may overcome these limitations and result in greater therapeutic efficacy of peptide-based cancer vaccines. To study the fate of melanoma-specific CD8+ T cells after peptide vaccination, we tracked T cell receptor-transgenic pmel-1 T cells in mice vaccinated with heteroclitic gp100_25-33 peptide emulsified in IFA. Splenic pmel-1 CD8+ T cells were purified at 6 and 21 days after vaccination with either gp100/IFA/covax or gp100/saline/covax, and then their total RNA was extracted and used for comparison by gene expression profiling.

Krüppel-like factor 4 regulates the cytolytic effector function of exhausted CD8 T-cells [ATAC-Seq]

Project description:Since exhausted CD8 T-cells are known to have a strong epigenetic imprint, which is a major obstacle for reinvigoration, we investigated whether the induced Klf4 expression could change the epigenetic status of the exhausted CD8 T-cells. For this, we performed ATAC-sequencing and compared chromatin landscapes between naïve, in vitro generated effector, exhausted (GFP-induced), and reinvigorated (KLF4-induced) CD8 T-cells.

beta-catenin in dendritic cells negatively regulates CD8 T cell im-mune responses through the immune checkpoint molecule Tim-3

Project description:Recent studies have demonstrated that b-catenin in dendritic cells (DCs) serves as a key mediator in promoting both CD4 and CD8 T cell tolerance, although the mechanisms underlying how b-catenin exerts its functions remains incompletely understood. Here we report that activation of b-catenin leads to the up-regulation of inhibitory molecule T-cell immunoglobulin and mucin domain 3 (Tim-3) in type 1 conventional DCs (cDC1s). Using a cDC1-targeted vaccine model with anti-DEC-205 engineered to express the melanoma antigen--human gp100 (anti-DEC-205-hgp100), we demonstrated that CD11c-b-cateninactive mice exhibited impaired cross-priming and memory re-sponses of gp100-specific CD8 T (Pmel-1) cells upon immunization with anti-DEC-205-hgp100. Sin-gle cell RNA sequencing (scRNA-seq) analysis revealed that b-catenin in DCs negatively regulated transcription programs for effector function and proliferation of primed Pmel-1 cells, correlating with suppressed CD8 T cell immunity in CD11c-b-cateninactive mice. Further experiments showed that treating CD11c-b-cateninactive mice with anti-Tim-3 antibody upon anti-DEC-205-hgp100 vac-cination led to restored cross-priming and memory responses of gp100-specific CD8 T cells, sug-gesting that anti-Tim-3 treatment likely synergizes with DC vaccines to improve their efficacy. In-deed, treating B16F10-bearing mice with DC vaccines using anti-DEC-205-hgp100 in combination with anti-Tim-3 treatment resulted in significantly reduced tumor growth, compared to treatment with DC vaccine alone. Taken together, we have identified the b-catenin/Tim-3 axis as a novel mech-anism to inhibit anti-tumor CD8 T cell immunity, and that combination immunotherapy of a DC-targeted vaccine with anti-Tim-3 treatment leads to improved anti-tumor efficacy.

A TCR/anti-CD3 bispecific fusion protein targeting gp100 potently activated anti-tumor immune responses in metastatic melanoma

Project description:Tumor-specific cytotoxic T cells are required for effective immunotherapy. Here we introduce a bispecific fusion protein (tebentafusp) designed to target gp100 (a melanoma-associated antigen) through a high affinity T cell receptor binding domain, and through an anti-CD3 effector domain re-directs any cytotoxic T cell, regardless of its intrinsic specificity, to kill gp100-expressing tumor cells. In patients with metastatic melanoma, tebentafusp showed anti-tumor activity and manageable and predictable side effects. Notably, tebentafusp induced an increase in serum CXCL10 (a T cell attractant), and a reduction in circulating CXCR3+ CD8+ T cells together with an increase in cytotoxic T cells in the tumor microenvironment (TME). Furthermore, the appearance of rash, likely due to cytotoxic T cells targeting of gp100-expressing skin melanocytes, or an increase in serum CXCL10 showed a positive association with patient survival. Taken together, these results suggest that re-directing T cells using a gp100-targeting T cell receptor/anti-CD3 bispecific fusion protein may provide benefit to patients with metastatic melanoma.
