Abstract
CCR8 is a chemokine receptor expressed principally on regulatory T cells (Treg) and is known to be critical for CCR8+ Treg-mediated immunosuppression. Recent studies have demonstrated that CCR8 is uniquely upregulated in human tumor-resident Tregs of patients with breast, colon, and lung cancer when compared with normal tissue-resident Tregs. Therefore, CCR8+ tumor-resident Tregs are rational targets for cancer immunotherapy. Here, we demonstrate that mAb therapy targeting CCR8 significantly suppresses tumor growth and improves long-term survival in colorectal tumor mouse models. This antitumor activity correlated with increased tumor-specific T cells, enhanced infiltration of CD4+ and CD8+ T cells, and a significant decrease in the frequency of tumor-resident CD4+CCR8+ Tregs. Tumor-specific CD8+ T cells displayed lower expression of exhaustion markers as well as increased functionality upon restimulation. Treatment with anti-CCR8 mAb prevented de novo induction and suppressive function of Tregs without affecting CD8+ T cells. Initial studies explored a combinatorial regimen using anti-CCR8 mAb therapy and a Listeria monocytogenes-based immunotherapy. Anti-CCR8 mAb therapy synergized with L. monocytogenes-based immunotherapy to significantly delay growth of established tumors and to prolong survival. Collectively, these findings identify CCR8 as a promising new target for tumor immunotherapy and provide a strong rationale for further development of this approach, either as a monotherapy or in combination with other immunotherapies.Significance: Inhibition of CCR8 represents a promising new cancer immunotherapy strategy that modulates tumor-resident regulatory T cells to enhance antitumor immunity and prolong patient survival.

Very Low Numbers of CD4 + FoxP3 + Tregs Expanded in Donors via TL1A-Ig and Low-Dose IL-2 Exhibit a Distinct Activation/Functional Profile and Suppress GVHD in a Preclinical Model. Biol Blood Marrow Transplant 2018; 24:1788-1794.

Abstract
Regulatory T cells (Tregs) are essential for the maintenance of tolerance and immune homeostasis. In allogeneic hematopoietic stem cell transplantation (aHSCT), transfer of appropriate Treg numbers is a promising therapy for the prevention of graft-versus-host disease (GVHD). We have recently reported a novel approach that induces the marked expansion and selective activation of Tregs in vivo by targeting tumor necrosis factor receptor superfamily 25 (TNFRSF25) and CD25. A potential advance to promote clinical application of Tregs to ameliorate GVHD and other disorders would be the generation of more potent Treg populations. Here we wanted to determine if very low doses of Tregs generated using the "2-pathway" stimulation protocol via TL1A-Ig fusion protein and low-dose IL-2 (targeting TNFRSF25 and CD25, respectively) could be used to regulate preclinical GVHD. Analysis of such 2-pathway expanded Tregs identified higher levels of activation and functional molecules (CD103, ICOS-1, Nrp-1, CD39, CD73, il-10, and tgfb1) versus unexpanded Tregs. Additionally, in vitro assessment of 2-pathway stimulated Tregs indicated enhanced suppressor activity. Notably, transplant of extremely low numbers of these Tregs (1:6 expanded Tregs/conventional T cells) suppressed GVHD after an MHC-mismatched aHSCT. Overall, these results demonstrate that 2-pathway stimulated CD4+ FoxP3+ Tregs were quantitatively and qualitatively more functionally effective than unexpanded Tregs. In total, the findings in this study support the notion that such 2-pathway stimulated Tregs may be useful for prevention of GVHD and ultimately promote more widespread application of aHSCT in the clinic.

Abstract
CD4+Foxp3+ regulatory T-cells (Tregs) are a unique subset of helper T-cells, which regulate immune response and establish peripheral tolerance. Tregs not only maintain the tone and tenor of an immune response by dominant tolerance but, in recent years, have also been identified as key players in resolving tissue inflammation and as mediators of tissue healing. Apart from being diverse in their origin (thymic and peripheral) and location (lymphoid and tissue resident), Tregs are also phenotypically heterogeneous as per the orientation of ongoing immune response. In this review, we discuss the recent advances in the field of Treg biology in general, and non-lymphoid and tissue-resident Tregs in particular. We elaborate upon well-known visceral adipose tissue, colon, skin, and tumor-infiltrating Tregs and newly identified tissue Treg populations as in lungs, skeletal muscle, placenta, and other tissues. Our attempt is to differentiate Tregs based on distinctive properties of their location, origin, ligand specificity, chemotaxis, and specific suppressive mechanisms. Despite ever expanding roles in maintaining systemic homeostasis, Tregs are employed by large varieties of tumors to dampen antitumor immunity. Thus, a comprehensive understanding of Treg biology in the context of inflammation can be instrumental in effectively managing tissue transplantation, autoimmunity, and antitumor immune responses.

Abstract
The current review focuses on two chemokine-chemokine receptor interactions: CXCL10-CXCR3 and CCL1-CCR8. We show that CXCL10 acts on CD4+ and CD8+ T cells to enhance anti-tumor immunity, and explore the translational perspectives of these findings. As for CCR8 very recently, we identified a novel subset of CCR8+CD4+FOXp3+ regulatory T cells (Treg) that are major drivers of immune regulation. We observed that one of the four CCR8 ligands, CCL1, produced by these cells, potentiates their suppressive activity via induction of CCR8, FOXp3, CD39, Granzyme-B, and IL-10 in a positive feedback mechanism, making them master drivers of immune regulation. Collectively, this suggests blocking the CCR8-CCL1 interaction, alone or combined with other immune checkpoint inhibitors, as an approach to treat malignant diseases.

Abstract
While desired for the cure of allergy, regulatory immune cell subsets and nonclassical Th2-biased inflammatory mediators in the tumour microenvironment can contribute to immune suppression and escape of tumours from immunological detection and clearance. A key aim in the cancer field is therefore to design interventions that can break immunological tolerance and halt cancer progression, whereas on the contrary allergen immunotherapy exactly aims to induce tolerance. In this position paper, we review insights on immune tolerance derived from allergy and from cancer inflammation, focusing on what is known about the roles of key immune cells and mediators. We propose that research in the field of AllergoOncology that aims to delineate these immunological mechanisms with juxtaposed clinical consequences in allergy and cancer may point to novel avenues for therapeutic interventions that stand to benefit both disciplines.
