Updated chapters describe either the most popular methods or those processes that have evolved the most since the past edition. Additionally, a large portion of the volume is devoted to clinical cytometry. Characterization of hepatitis B virus (HBV)-specific T-cell dysfunction in chronic HBV infection. Mass cytometry has been instrumental in the comprehensive characterization of TEX function. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. A signal cascade is usually initiated, altering the behavior . J Immunol. Similar observations have been made using flow cytometry and in patients with non-small cell lung cancer (4). Whether CD4 T cells "help" CD8 T cells to control Mycobacterium tuberculosis infection is unknown. CD3, a T cell specific marker, is necessary to differentiate T cells from . (2019) 20:326–36. Data-driven visualizations in this figure were computed based on a dataset published in Bengsch et al. This book illustrates the intimate relationship between alveolar macrophages and Mycobacterium tuberculosis (M.tb.), and the former’s role in both innate and adaptive immunity against M.tb. It covers research done over the last decade. Duraiswamy J, Ibegbu CC, Masopust D, Miller JD, Araki K, Doho GH, et al. Applied scientists working on compositional data analysis in any field of science, both in academia and professionals will benefit from this book, along with graduate students in any field of science working with compositional data. Moreover, 182 genes down-regulated in TEX were identified that were specifically suppressed on a transcriptional level and lacked accessibility of adjacent enhancers. CD3, a T cell specific marker, is necessary to differentiate T cells from . In sharp contrast, antigen-specific T cells during chronic infection progressively develop major features of exhaustion, including the up-regulation of inhibitory receptor expression and functional impairment (e.g., consecutive loss of IL-2, TNF and IFN-γ production) (6, 7, 19, 20).

CD57) from children with symptomatic malaria, asymptomatic malaria and healthy controls using flow cytometry. The ability to profile more than 40 markers per cell is particularly relevant for the differentiation of cell types for which low parametric characterization has proven difficult, such as exhausted CD8+ T cells (TEX). (2013) 31:545–52. J Virol. Customized flow cytometry panels can be created to monitor CD4+ or CD8+ T cell exhaustion, and the level of complexity of these panels is only limited by the type of cytometer available for use. These highly activated T cells in chronic infection are thought to arise from an intermediate trajectory of TEX (expressing e.g., PD-1, 2B4, TIGIT) after encountering additional antigen stimulation and inhibitory signals. The gamma-delta T-cells are also seen in extramedullary tissue such as skin and gastrointestinal tract. DARCEY L.

Wherry EJ, Blattman JN, Murali-Krishna K, Van Der Most R, Ahmed R. Viral persistence alters CD8 T-cell immunodominance and tissue distribution and results in distinct stages of functional impairment. Several bioinformatic strategies have been developed that allow more intuitive visualization of the high-dimensional data using dimension reduction approaches [most prominently based on visualization of “t stochastic neighborhood embedding,” tSNE (60)], and cluster identification strategies in high-dimensional data [e.g., SPADE (61), FlowSOM (62), PhenoGraph (63) and many more] or trajectory inferences that are reviewed elsewhere (64–66). IL-10 and PD-L1 operate through distinct pathways to suppress T-cell activity during persistent viral infection.

Day CL, Kaufmann DE, Kiepiela P, Brown JA, Moodley ES, Reddy S, et al. In the next few blog posts, I will discuss selection of markers for studying PBMC populations using flow cytometry and the best way to arrange these markers in flow cytometry staining panels. Furthermore, this analytic approach also identified additional exhaustion markers induced on TEX, such as surface proteins CD7, CXCR5, cytotoxic molecule granzyme K or transcription factors Helios and TOX, many of which are also found enriched in tumor-infiltrating lymphocytes by single-cell transcriptomics (46, 47). Moreover, transient permeabilization protocols frequently used for intracellular barcoding in mass cytometry trials can reduce anti-PD-1 staining. Wherry, EJ, 2011, T cell Exhaustion, Nature Immunology, 12:  492–499. Cell-based modalities such as CAR-T and CAR-NK cell therapies often utilize flow cytometry to monitor the persistence and differentiation of the cell therapy products, as well as their pharmacology by monitoring target cell depletion. of the CAR T cells under investigation, orthogonal Agilent NovoCyte flow cytometry assays can be performed to evaluate T cell activation, differentiation, and exhaustion. Following such an approach, sets of epigenomically regulated exhaustion-specific genes have been recently identified, including 313 genes specifically up-regulated in TEX compared to TN, TEFF, and TMEM that displayed higher gene expression by transcriptome analysis and concomitant changes in enhancer accessibility (45). doi: 10.1016/j.jhep.2014.07.005, 11. Reinvigoration of TEX compared to tumor mass was identified as a major correlate of the clinical response of patients with malign melanoma receiving checkpoint therapy with anti-PD-1 antibodies (3). Moreover, this strategy also predicted down-regulation of markers associated with naïve and/or memory T cells, such as CCR7, CD73, CD127 and transcription factor TCF-1 on TEX (Table 1). (2016) 45:389–401. Chen L., and Flies, DB, 2013, Molecular Mechanisms of T cell co-stimulation and Co-Inhibition, Nat Rev Immunol 13:  227-242. During acute resolving viral infection, viral clearance after induction of functional effector T cells is followed by the establishment of a pool of memory T cells (17, 18) (Figure 1). TEX are emerging as a central correlate and useful biomarker of successful immune checkpoint blockade therapies. doi: 10.1128/JVI.78.11.5535-5545.2004, 74. doi: 10.4049/jimmunol.0900182, 54. Classifiersusing only a list of cell surface genes (Chihara et al., 2018) also achieved high . Note: If using whole blood, samples should go through a red blood cell lysis step at this point. doi: 10.1016/j.immuni.2012.08.021, 25. Notably, at later time points, the global differentiation program of TEX assessed on the transcriptional and epigenetic level remains stable even after checkpoint blockade intervention and functional reinvigoration (12). The pan T cell markers are generally expressed; however, aberrant marking of one or more is common. CD69 is probably the most common activation marker. Flow cytometry has advanced rapidly allowing us to be able to define a detailed characterization of T cells in both states. Using Flow Cytometry to Phenotype Exhausted T Cells. Gastroenterology. One mechanism to prevent overstimulation is for effector cells to upregulate inhibitory receptors (IR) on their cell surface such as PD-1, CTLA-4, LAG3, TIM3, TIGIT, CD244, CD160 and others.     While IR provide an important check on the immune system, this same mechanism can be exploited by virus and cancers to avoid the immune system. SHE RECENTLY JOINED FCSL AS THEIR CHIEF SCIENTIFIC OFFICER. Identification of TEX without prior knowledge of antigen specificity has remained challenging and is a major obstacle for immune phenotyping in human disease—in particular in cancer—where many tumor antigens especially neoantigens are unknown and tools for assessment of antigen-specific T cell populations are limited. However, phenotypic distinction of TEX from TEFF and TMEM can often be challenging since many molecules expressed by TEX can also be expressed by effector and memory T cell populations. In contrast, persistent antigen stimulation, reduced costimulation in the presence of coinhibitory signals and prolonged exposure to inflammatory cues are main drivers of the differentiation toward the exhausted T cell (TEX) fate, including an up-regulation of inhibitory receptors (IRs).

The transcription factor FoxO1 sustains expression of the inhibitory receptor PD-1 and survival of antiviral CD8(+) T cells during chronic infection. Flow cytometry can separate the three DC subsets using BDCA markers: Myeloid cDC1 express BDCA-3 (CD141), cDC2 express BDCA-1 (CD1c), and pDC express BDCA-2 (CD303) (Breton et al., 2015; Collin & Bigley, 2018; Collin, Mcgovern, & Haniffa, 2013). Follicular CD8 T cells accumulate in HIV infection and can kill infected cells in vitro via bispecific antibodies. Dynamic programmed death 1 expression by virus-specific CD8 T cells correlates with the outcome of acute hepatitis B. Gastroenterology. doi: 10.1016/j.immuni.2014.10.013, 65. Induction of several molecular programs linked to recent T cell activation remains a shared feature of many TEX populations with effector T cells (e.g., CD38, CD39, PD-1), while programs of homeostasis and access to anatomic niches can be shared by other TEX populations (including those linked to disease control) with memory T cells. PD-1 expression on HIV-specific T cells is associated with T-cell exhaustion and disease progression. (2016) 12:e1005661. PLoS Pathog. Bengsch B, Johnson AL, Kurachi M, Odorizzi PM, Pauken KE, Attanasio J, et al. Moreover, TEX expressing CXCR5 have been linked to better control of HIV infection and are thought to constitute a major subset responding to checkpoint therapy (41, 42, 77). While combination stainings with secondary antibodies against the checkpoint reagents are established, these remain to provide challenges for bioinformatic analysis.

As a consequence, cluster identification based on the complete high-dimensional data is often preferred. doi: 10.1038/nature22367, 56. Immunity. (2017) 170:1120–33.e1117.  When CD8+ T cells are primed during infection with chronic LCMV, and then removed after 1 week of exposure to the infection, they can still differentiate into fully functional CD8+ memory T cells.  But, when they are exposed to persistent antigen for 2-4 weeks, they become exhausted, and cannot recover normal memory differentiation once removed from antigen exposure (Wherry and Karachi, 2015).  The severity, duration of antigen, and the loss of help from CD4+ T cells, lead to more severe exhaustion.  For example, in HIV, CD8+ T cell exhaustion worsens in the absence of CD4+ cells and IL-21.   Infections also lead to disruption of the lymphoid architecture and are associated with pathogenesis and poor immunity, as it impairs trafficking and interactions with cells necessary for T cell function. T-cell exhaustion is a broad term used to describe T cell dysfunction resulting from chronic stimulation. For example, the altered co-expression patterns of immuno-regulatory molecules on different TEX populations across different disease entities or even across different stages of disease suggest that the therapeutic efficacy of combination therapies (i.e., combined targeting of PD-1 and CTLA-4) could vary according to the TEX subset composition.

Gehring AJ, Ho ZZ, Tan AT, Aung MO, Lee KH, Tan KC, et al. Immunophenotyping by flow cytometry, a valuable research tool, uses the differential expression of cellular markers to isolate and characterize T cells and their subsets. T Cell Exhaustion. For example, 25 high-dimensional clusters of CD8+ T cells were identified using PhenoGraph analysis based on the analysis of exhaustion markers in a large and diverse cohort of patients with chronic HIV infection, lung cancer and healthy controls (45). total DNA. total T cells, CD4+ and CD8+ T cells were dramatically reduced in COVID-19 patients, especially among elderly patients (≥60 years of age) and in patients requiring Harvested cells were phenotyped by flow cytometry and evaluated for cytokine secretion by multiplex assays.

This allow for rapid analysis of a sample for morphology and multi-parameter fluorescence at both a single cell and population level (Barteneva, Fasler-Kan, & Vorobjev, 2012).IFC can track protein distributions within individual cells like a confocal or fluorescence microscope . However, it has become clear that those inhibitory receptors can also be expressed by functional effector T cells and may also be present on memory T cell populations and therefore lack specificity (36–39). Flow cytometry studies are used to identify and quantify immune cells and characterize hematological malignancies.1 They can measure: cell size.

This volume provides protocols to successfully apply cutting-edge technologies to characterize the biology of T cells at an unprecedented level of complexity. Phenotypically, these disease-associated exhausted T cells displayed co-expression of exhaustion-specific receptors such as PD-1, CD38 and a transcription factor signature characterized by high Eomes and TOX but low TCF-1 expression (Figure 3). doi: 10.1146/annurev-immunol-041015-055318, 44. (2010) 207:2175–86. (2003) 170:477–86. Similarly, cell cycle activity assessed by Ki-67 combined with exhaustion marker phenotyping has been pivotal in mass cytometry analysis of responding TEX during checkpoint therapies (3). (12). Examples of gating for proliferation and cytokine production are shown for a rapid progressor (T1D-02) and a slow progressor (T1D-34) with low (4%) and high (60%) frequencies of cluster 1, respectively.
