Programmed cell death-1 receptor mediated regulation of Tbet+NK1.1- Innate Lymphoid Cells Within the Tumor Microenvironment

ABSTRACT: Innate Lymphoid Cells (ILCs) play a key role in tissue mediated immunity and can be controlled by co-receptor signaling. Here we define a subset of ILCs that are Tbet+NK1.1- and are present within the tumor microenvironment (TME). We show programmed death-1 receptor (PD-1) expression on ILCs within TME is found in Tbet+NK1.1-ILCs. PD-1 significantly controlled the proliferation and function of Tbet+NK1.1-ILCs in multiple murine and human tumors. We found tumor derived lactate enhanced PD-1 expression on Tbet+NK1.1-ILCs within the TME, which resulted in dampened mTOR signaling along with increased fatty acid uptake. In line with these metabolic changes, PD-1 deficient Tbet+NK1.1-ILCs expressed significantly increased IFNg, granzyme B and K. Furthermore, PD-1 deficient Tbet+NK1.1- ILCs contributed towards diminished tumor growth in an experimental murine model of melanoma. These data demonstrate that PD-1 can regulate anti-tumor responses of Tbet+NK1.1-ILCs within the tumor microenvironment.

Expression data from Tbet+ and Tbet- Memory B cells

Project description:The role of antibody and B cells in preventing infection is established. In contrast, the role of B cell responses in containing chronic infections remains poorly understood. IgG2a (IgG1 in humans) can prevent acute infections and T-bet promotes IgG2a isotype switching. However, whether IgG2a and B cell-expressed T-bet influence the host-pathogen balance during persisting infections is unclear. Here we demonstrate that B cell specific loss of T-bet prevents control of persisting viral infection. T-bet in B cells not only controlled IgG2a production, but also mucosal localization, proliferation, glycosylation, and a broad transcriptional program. T-bet controlled a broad antiviral program in addition to IgG2a since T-bet in B cells was imÂportant even in the presence of virus-specific IgG2a. Our data supports a model in which T-bet is a universal controller of antiviral immunity across multiple immune lineages. NaÃ¯ve, Tbet+, and Tbet- Memory B cells were assayed for gene expression Tbet GFP reporter mice were infected with LCMV clone 13, and target B cell populations were sorted from splenocytes at day 10 post-infection

Batf3-dendritic cells and 4-1BB/4-1BB ligand axis are required at the effector phase within the tumor microenvironment for PD-1/PD-L1 blockade efficacy

Project description:The cellular source of positive signals that reinvigorate T cells within the tumor microenvironment (TME) for the therapeutic efficacy of PD-1/PD-L1 blockade has not been clearly defined. We now show that Batf3-lineage dendritic cells (DCs) are essential in this process. Flow cytometric analysis, gene-targeted mice, and blocking antibody studies revealed that 4-1BBL was a major positive costimulatory signal provided by these DCs within the TME, that translated to CD8+ T cell functional reinvigoration and tumor regression. Immunofluorescence and spatial transcriptomics on human tumor samples revealed clustering of Batf3+ DCs and CD8+ T cells, which correlated with anti-PD-1 efficacy. In addition, proximity to Batf3+ DCs within the TME was associated with CD8+ T cell transcriptional states linked to anti-PD-1 response. Our results demonstrate that Batf3+ DCs within the TME are critical for PD-1/PD-L1 blockade efficacy, and indicate a major role for the 4-1BB/4-1BBL axis during this process.

Cutting Edge: IL-4, IL-21, and IFN-g Interact to Govern TBET and CD11c Expression in TLR-Activated B Cells

Project description:T-Box Expressed in T cells (TBET) and CD11c expression in B cells is linked with IgG2c isotype switching, virus-specific immune responses, and humoral autoimmunity. However, the activation requisites and regulatory cues governing TBET and CD11c expression remain poorly defined. In this article, we reveal a relationship among TLR engagement, IL-4, IL-21, and IFN-g that regulates TBET expression in B cells. We find that IL-21 or IFN-g directly promote TBET+ expression in the context of TLR engagement. Further, IL-4 antagonizes TBET induction. Finally, IL-21, but not IFN-g, promotes CD11c expression independent of TBET. Using influenza virus and Heligmosomoides polygyrus infections, we show that these interactions function in vivo to determine whether TBET+ and CD11c+ B cells are formed. These findings suggest that TBET+ B cells seen in health and disease share the common initiating features of TLR-driven activation within this circumscribed cytokine milieu.

Tbet regulates the accessible chromatin of Be1 B cells

Project description:To investigate the role of Tbet in B cell differentiation to "effector-like" antibody secreting cells (ASC's) we utilized an ex vivo culture system to differentiate B cells in the presence of Th1 (Be1) or Th2 (Be2) polarized T cells. To determine the role of Tbet in Be1 cell differentiation we performed ATAC-seq on Wt Be1 and Tbet negative (TbetNeg) Be1 cells and Wt Be2 and Tbet negative (TbetNeg) Be2 cells. Collectively, these data show that T-bet serves as master regulator for the Be1 cell fate and is required to program chromatin accessibility during ASC differentiation in Be1 cells.

Kinetics of Tbet+ B cells during LCMV infection

Project description:Inflammatory (B220+ CD19+ CD44+ CD11c+ Tbet-AmCyanhi) B cells were sorted from female Tbet-AmCyan reporter mice at day 8, 10, and 15 post infection with LCMV-Armstrong. RNA-seq was employed to assess transcriptional changes in inflammatory B cells throughout the infection.

Tbet vs Eomes [RNA-Seq]

Project description:T-bet and Eomes are related T-box transcription factors that control NK cell development. This study was designed to understand the specific roles of Eomes and T-bet in regulating gene expression. RNAseq data were generated for immature (CD11b- CD27+) and mature (CD11b+ CD27-) NK cells from T-bet KO (Tbet Ho) or control mice (Tbet WT) or from Eomes KO (Eomes Ho) or control mice (NK-Cre). Three samples were generated for each condition (Tri 1, 2, 3).
