Cytometric immunophenotyping is a powerful tool to discover and implement T-cell biomarkers of type 1 diabetes (T1D) progression and response to clinical therapy. Although many discovery-based T-cell biomarkers have been described, to date, no such markers have been widely adopted in standard practice. The heterogeneous nature of T1D and lack of standardized assays and experimental design across studies is a major barrier to the broader adoption of T-cell immunophenotyping assays. There is an unmet need to harmonize the design of immunophenotyping assays, including those that measure antigen-agnostic cell populations, such that data collected from different clinical trial sites and T1D cohorts are comparable, yet account for cohort-specific features and different drug mechanisms of action. In these Guidelines, we aim to provide expert advice on how to unify aspects of study design and practice. We provide recommendations for defining cohorts, method implementation, as well as tools for data analysis and reporting by highlighting and building on selected successes. Harmonization of cytometry-based T-cell assays will allow researchers to better integrate findings across trials, ultimately enabling the identification and validation of biomarkers of disease progression and treatment response in T1D.

REGULATORY T cells ,LACTIC acid ,T cells ,CELL populations ,ACIDITY - Abstract
The metabolic milieu is emerging as a major contributing factor in the maintenance of the immunosuppressive microenvironment within tumors. In particular, the presence of lactic acid produced by highly glycolytic cancer cells is known to suppress antitumor immune cell subsets while promoting immunosuppressive cell populations, such as regulatory T cells (Tregs). Unlike conventional T cells, Tregs have a unique, potent ability to take up lactic acid to fuel both mitochondrial metabolism and gluconeogenesis, thus supporting suppressive function and proliferation. In this issue of the European Journal of Immunology [Eur. J. Immunol. 2023.53:2250258], Rao et al. uncover a novel mechanism by which lactic acid can support Treg accumulation within tumors in mice. This study shows that lactic acid, through a pH‐dependent mechanism rather than lactate itself, promotes TGFβ‐induced differentiation of Tregs from conventional CD4+ T cells. These findings build on the already multifaceted role of lactic acid in maintaining an immunosuppressive tumor microenvironment. [ABSTRACT FROM AUTHOR]

REGULATORY T cells ,IMMUNOLOGICAL tolerance ,T cells ,TRANSCRIPTION factors ,IMMUNE response - Abstract
Treg therapy holds promise as a potentially curative approach to establish immune tolerance in transplantation and autoimmune disease. An outstanding question is whether therapeutic Tregs have the potential to transdifferentiate into effector T‐cells and, thus, exacerbate rather than suppress immune responses. In mice, the transcription factor Helios is thought to promote Treg lineage stability in a range of inflammatory contexts. In humans, the role of Helios in Tregs is less clear, in part, due to the inability to enrich and study subsets of Helios‐positive versus Helios‐negative Tregs. Using an in vitro expansion system, we found that loss of high Helios expression and emergence of an intermediate Helios (Heliosmid)‐expressing population correlated with Treg destabilization. We used CRISPR/Cas9 to genetically ablate Helios expression in human naive or memory Tregs and found that Helios‐KO and unedited Tregs were equivalent in their suppressive function and stability in inflammation. Thus, high Helios expression is a marker, but not a driver, of human Treg stability in vitro. These data highlight the importance of monitoring Helios expression in therapeutic Treg manufacturing and provide new insight into the biological function of this transcription factor in human T‐cells.

SUPPRESSOR cells ,CROSSTALK ,INFLAMMATORY bowel diseases ,HUMAN biology ,TYPE 1 diabetes - Abstract
Regulatory T cells (Tregs) have a critical role in maintaining self‐tolerance and immune homeostasis. There is much interest in using Tregs as a cell therapy to re‐establish tolerance in conditions such as inflammatory bowel disease and type 1 diabetes, with many ongoing clinical studies testing the safety and efficacy of this approach. Manufacturing of Tregs for therapy typically involves ex vivo expansion to obtain sufficient cell numbers for infusion and comes with the risk of altering the activity of key biological processes. However, this process also offers an opportunity to tailor Treg function to maximize in vivo activity. In this review, we focus on the roles of antigen‐presenting cells (APCs) in the generation and function of Tregs in humans. In addition to stimulating the development of Tregs, APCs activate Tregs and provide signals that induce specialized functional and homing marker expression. Cross talk between Tregs and APCs is a critical, often under‐appreciated, aspect of Treg biology, with APCs mediating the key properties of infectious tolerance and bystander suppression. Understanding the biology of human Treg‐APC interactions will reveal new ways to optimize Treg‐based therapeutic approaches. [ABSTRACT FROM AUTHOR]

- Abstract
Treg cells control immune responses to self and nonharmful foreign antigens. Emerging data from animal models indicate that Treg cells function in both secondary lymphoid organs and tissues, and that these different microenvironments may contain specialized subsets of Treg cells with distinct mechanisms of action. The design of therapies for the restoration of tissue-localized immune homeostasis is dependent upon understanding how local immune responses are influenced by Treg cells in health versus disease. Here we review the current state of knowledge about human Treg cells in four locations: the skin, lung, intestine, and joint. Despite the distinct biology of these tissues, there are commonalities in the biology of their resident Treg cells, including phenotypic and functional differences from circulating Treg cells, and the presence of cytokine-producing (e.g. IL-17
+ ) FOXP3+ cells. We also highlight the challenges to studying tissue Treg cells in humans, and opportunities to use new technologies for the detailed analysis of Treg cells at the single-cell level. As emerging biological therapies are increasingly targeted toward tissue-specific effects, it is critical to understand their potential impact on local immune regulation.

- Abstract
The suppression of inappropriate immune responses by Treg cells is one of the major ways that the body maintains immune tolerance and homeostasis. Since defects in the suppressive capacity of Treg cells underlie many different immune-mediated diseases, there is great interest in developing ways to track the number and function of Treg cells as biomarkers of tolerance and in devising ways to enhance their function therapeutically. However, the methods of studying human Treg cells are fraught with technical challenges that can often lead to misinterpretation. The most common way to determine the suppressive capacity of human Treg cells is to measure their ability to suppress the proliferation of responding CD4
+ T cells. Here, we discuss the technical considerations that must be taken into account when performing suppression of T-cell proliferation assays with human Treg cells. We also consider how T cells may falsely appear suppressive because of dying cells in the system, improper resting of T-cell lines prior to the assay, or insufficient proliferation of the responding T cells. We propose that, in the future, classification of a population of cells as 'regulatory' should rely on more than a simple test for blockade of CD4+ T-cell proliferation.

- Abstract
CD4
+ CD25+ Foxp3+ regulatory T (TREG ) cells are critical mediators of peripheral immune tolerance, and abrogation of their function provokes a variety of autoimmune and inflammatory states including inflammatory bowel disease. In this study, we investigate the functional dynamics of TREG -cell responses in a CD4+ T-cell-induced model of intestinal inflammation in αβ T-cell-deficient (TCR-β−/− ) hosts to gain insights into the mechanism and cellular targets of suppression in vivo. We show that CD4+ T effector cell transfer into T-cell-deficient mice rapidly induces mucosal inflammation and colitis development, which is associated with prominent Th1 and Th17 responses. Interestingly, we unveil a prominent role for resident γδ T cells in mucosal inflammation as they promote Th1 and particularly Th17 responses in the early phase of inflammation, thus exacerbating colitis development. We further demonstrate that CD4+ CD25+ Foxp3+ TREG cells readily inhibit these responses and mediate disease protection, which correlates with their accumulation in the draining LN and lamina propria. Moreover, TREG cells can directly suppress γδ T-cell expansion and cytokine production in vitro and in vivo, suggesting a pathogenic role of γδ T cells in intestinal inflammation. Thus, functional alterations in TREG cells provoke dysregulated CD4+ and γδ T-cell responses to commensal antigens in the intestine. [ABSTRACT FROM AUTHOR]- Published

The marriage between immunology and cytometry is one of the most stable and productive in the recent history of science. A rapid search in PubMed shows that, as of July 2017, using “flow cytometry immunology” as a search term yields more than 68 000 articles, the first of which, interestingly, is not about lymphocytes. It might be stated that, after a short engagement, the exchange of the wedding rings between immunology and cytometry officially occurred when the idea to link fluorochromes to monoclonal antibodies came about. After this, recognizing different types of cells became relatively easy and feasible not only by using a simple fluorescence microscope, but also by a complex and sometimes esoteric instrument, the flow cytometer that is able to count hundreds of cells in a single second, and can provide repetitive results in a tireless manner. Given this, the possibility to analyse immune phenotypes in a variety of clinical conditions has changed the use of the flow cytometer, which was incidentally invented in the late 1960s to measure cellular DNA by using intercalating dyes, such as ethidium bromide. The epidemics of HIV/AIDS in the 1980s then gave a dramatic impulse to the technology of counting specific cells, since it became clear that the quantification of the number of peripheral blood CD4+ T cells was crucial to follow the course of the infection, and eventually for monitoring the therapy. As a consequence, the development of flow cytometers that had to be easy-to-use in all clinical laboratories helped to widely disseminate this technology. Nowadays, it is rare to find an immunological paper or read a conference abstract in which the authors did not use flow cytometry as the main tool to dissect the immune system and identify its fine and complex functions. Of note, recent developments have created the sophisticated technology of mass cytometry, which is able to simultaneously identify dozens of molecules at the single cell level and allows us to better understand the complexity and beauty of the immune system.

- Abstract
We optimized a method to detect FOXP3 by mass cytometry and compared the resulting data to conventional flow cytometry. We also demonstrated the utility of the protocol to profile antigen-specific Tregs from whole blood, or Tregs from tissues such as cord blood, thymus and synovial fluid., (© 2018 WILEY-VCH Verlag GmbH & Co.

- Abstract
CD4(+) CD25(+) Foxp3(+) regulatory T (T(REG) ) cells are critical mediators of peripheral immune tolerance, and abrogation of their function provokes a variety of autoimmune and inflammatory states including inflammatory bowel disease. In this study, we investigate the functional dynamics of T(REG) -cell responses in a CD4(+) T-cell-induced model of intestinal inflammation in αβ T-cell-deficient (TCR-β(-/-) ) hosts to gain insights into the mechanism and cellular targets of suppression in vivo. We show that CD4(+) T effector cell transfer into T-cell-deficient mice rapidly induces mucosal inflammation and colitis development, which is associated with prominent Th1 and Th17 responses. Interestingly, we unveil a prominent role for resident γδ T cells in mucosal inflammation as they promote Th1 and particularly Th17 responses in the early phase of inflammation, thus exacerbating colitis development. We further demonstrate that CD4(+) CD25(+) Foxp3(+) T(REG) cells readily inhibit these responses and mediate disease protection, which correlates with their accumulation in the draining LN and lamina propria. Moreover, T(REG) cells can directly suppress γδ T-cell expansion and cytokine production in vitro and in vivo, suggesting a pathogenic role of γδ T cells in intestinal inflammation. Thus, functional alterations in T(REG) cells provoke dysregulated CD4(+) and γδ T-cell responses to commensal antigens in the intestine., (Copyright © 2011 WILEY-VCH Verlag GmbH & Co.

- Abstract
One of the defining features of the majority of FOXP3(+) Tregs is their inability to produce typical T-cell-derived cytokines. Little is known, however, about their capacity to produce chemokines. As Tregs are constitutively present in, and rapidly traffic to, non-lymphoid tissues, we hypothesized that they may produce chemokines to direct the composition of cells that infiltrate inflamed tissues. Surprisingly, we found that Tregs produce high amounts of CXCL8 (IL-8), a potent neutrophil chemoattractant. Tregs also produced other CC and CXC family chemokines, including CCL2-5, CCL7, and CXCL10. Whereas ectopic expression of FOXP3 suppressed cytokine production, it significantly induced CXCL8. Moreover, supernatants from Tregs attracted neutrophils via a CXCL8-dependent mechanism. These data provide the first evidence that although classical Tregs are defined by their lack of proinflammatory cytokine production, they secrete significant quantities of chemokines and thus may have an unappreciated role in directing the recruitment of immune cells., (Copyright © 2011 WILEY-VCH Verlag GmbH & Co.
