Each symbol represents an individual subject. Statistical differences of interest, as measured using non-parametric Wilcoxon matched, paired two-tailed t tests, are described in the text.

We next compared T-bet expression levels within different B-cell populations to other known T-bet-expressing cell types. Memory B-cells thin black line generally expressed intermediate levels of T-bet; however, a small fraction expressed higher T-bet levels compared to plasmablasts.

Additionally, Eomes has not been investigated in the context of these populations in humans. Neither T-bet nor Eomes protein was detectable in circulating dendritic cell populations data not shown , suggesting that T-bet may be upregulated only under specific conditions. In this study, we characterized the resting expression patterns of the T-box transcription factors T-bet and Eomes in various resting peripheral blood immune cell populations to provide a basic platform for future studies dissecting their functions within these cell subsets.

Overall the same relationship holds true for Eomes expression in these populations, with the exception of B-cells, which lack Eomes, and NK cells where the more differentiated CD56 dim cells contain less Eomes than their predecessor CD56 bright cells. Taken together, our data suggest an essential role for T-bet and Eomes during peripheral terminal and, in some instances, memory cell differentiation. Additionally, our data would suggest that loss of T-bet or Eomes, depending on cell context, during activation of a number of different cell types would greatly diminish cell differentiation capacity and acquisition of terminal effector functions.

In HIV, for example, chronic HIV progressors display significantly lower levels of T-bet and its downstream cytotoxic gene target, perforin, within effector CD8 T-cells compared to elite controller counterparts 9 suggesting that if T-bet levels could be increased in these cells, effector function might be restored. Because T-bet and Eomes are members of the same family of transcription factors and because they are both associated with effector memory differentiation, they have proposed redundant roles in specific cell types.

However, our co-expression analysis reveal that this may not always be the case, and these factors might indeed have unique roles in the context of specific human cell subsets. Murine studies of transcriptional control support this NK cell maturation model, as Eomes is necessary for the generation and maintenance of mature NK cells 49 and T-bet is necessary to attain the most terminal stages of maturation 21 , These data support a model where T-bet likely is not required during early peripheral B-cell development and is first expressed during the germinal center reaction, where it regulates class switching.

As class-switched B-cells mature, T-bet likely plays a role in regulating other key functions of these cells. High frequencies of T-bet expression in plasmablasts indicate the importance of T-bet in these cells; however, mechanistic studies will be necessary to better understand the functions of T-bet in post-germinal center B-cells.

Taken together, our findings suggest potential novel functions for T-bet and Eomes in the context of a number of immune cell subsets and lay the foundation for future mechanistic work to define their numerous roles in human immune cells. James J. Knox, Michael R.

Eomes on the other hand was highly associated with expression of numerous inhibitory receptors. This relationship is associated with up-regulation of inhibitory receptors, impaired functional characteristics and a transitional memory differentiation phenotype.

Written informed consent was documented from all study subjects in accordance with the Declaration of Helsinki. Cell samples from 20 healthy controls were also collected from the Karolinska Institutet and Karolinska University Hospital Huddinge Table 1.

All individuals initiated ART in chronic phase of infection and no one experienced virological failure i. All flow cytometry panels were tested on the HIV-infected and healthy control subjects within a 2-month time interval to avoid intra- and inter-individual differences of the flow analysis. When anti-CDa was added at the start of the stimulation protocol [34] , monensin 0. Monoclonal antibodies against T-bet, Eomes and other intracellular markers were incubated with the cells for 1 hour at room temperature in the dark.

All specimens were acquired on the flow cytometer within the next 7 hours. In total, approximately 1,, events were collected per specimen. Antibody capture beads BD Biosciences were used to prepare individual compensation controls after separate stainings with all antibodies used in the experiments.

FlowJo 8. Most manual gatings were based on fluorescence minus one FMO gating strategies like previously described [35] , [36]. Experimental variables between two groups of individuals were analyzed using Mann-Whitney U test and Wilcoxon matched-pairs rank test. Correlations were assessed using non-parametric Spearman rank tests. Bonferroni corrections were applied to all cases where multiple testing was performed.

The large data set consisting of functional and inhibitory receptor frequencies from the Boolean combinations was analysed by principal component analysis PCA , an unsupervised statistical method for reducing data dimensionality while retaining the vital variation in fewer informative variables. The top 2 principle components PCs were plotted to visualize the trends such as clusters and outliers revealed by PCA. The Kolmogorov-Smirnov test was used to test the null hypothesis that the two groups of samples were drawn from the same distribution, where a large p-value suggests that the groups were drawn from the same distribution.

All the statistical analyses were performed using GraphPad Prism 5. Median and IQR are depicted in the scatter plots. Statistical analysis was performed with Wilcoxon matched-pairs single rank test. Wilcoxon matched-pairs single rank test was conducted to obtain P value. Spearman non-parametric test was used to test for correlations. Notably, similar associations were also observed for individuals on long-term ART and matched healthy controls Figure S1C.

Mann-Whitney tests were performed to conclude significance between the groups median and IQR. Wilcoxon matched-pairs single rank test was performed to show on significant differences between the groups. Permutation test was performed between the pie charts. Paired t-tests were used to compare differences between the groups.

Co-expression of PD-1, CD, and 2B4 has been closely linked to limited T cell functionality in mice and humans [12] , [16]. All individuals generated responses, except one with lack of an anti-CMV response. The KS test determines the probability that the two groups were drawn from the same distribution, where a P-value of 1 signifies that the groups were drawn from the same distribution.

The effector functions were examined using tetramers or pentamers and cognate epitope stimulations. We next evaluated the phenotypic composition of T-bet and Eomes expressing cells and as expected found that T-bet dim Eomes hi expressing cells were enriched and strongly associated with a transitional memory phenotype Figure 5B and Figure S5B. Median and IQR are shown for all populations.

Interestingly, we found tendencies of an inverse association pattern between T-bet and Eomes in terms of the inflammatory cytokine levels. To determine whether the viral load had a direct effect on the expression patterns of Eomes, T-bet and the inhibitory receptors, we analyzed samples collected before and at 2, 4, 8, 12—16 weeks, and 5—7 months after ART initiation.

These longitudinal analyses also allowed us to determine the kinetics of expression of these markers after succesful ART in 24 individuals. In contrast, the frequency of T-bet hi Eomes dim cells remained stable during the longitudinal assessment Figure 6A. This was linked to a steady T-bet dim Eomes hi expression that persisted over the entire study period Figure 6E. Individuals on long-term ART showed tendencies of lower co-expression of the inhibitory receptors compared to individuals at baseline or on ART for 6 months Figure 6G.

In our study, T-bet and Eomes were expressed in distinct patterns and linked to the exhausted phenotype observed in the murine studies. These results confirm previous findings by Hersperger et al , demonstrating decreased expression levels of T-bet in chronic HIV progressors [33]. The discrepancies between this study and our results here are most likely due to the use of different techniques to observe the levels of transcription factors.

While Ribeiro-dos-Santos et al isolated resting cell populations and used gene expression analysis to detect mRNA levels, we analyzed transcription factor protein expression on a single-cell level using flow cytometry. Furthermore, immunoblot analysis have previously confirmed that T-bet and Eomes expression in the nucleus and cytoplasm resembles what is distinguishable with flow cytometry [50].

Interestingly, we found a close correlation between the expression intensity of Eomes and monofunctionality measured as upregulation of CDa. T-bet has previously also been shown, in chromatin immunoprecipitation coupled with microarray analysis ChIP-ChIP , to bind and promote increased gene expression of Granzyme B and perforin in T cells [56]. This hypothesis is supported by the fact that chronically high antigen levels cause T cell exhaustion during chronic viral infections [57].

Whether the state of exhaustion therefore is directly proportional to antigen burden and only due to chronicity is therefore not entirely clear. Whether the expression profile of increased Eomes and lower T-bet is a consequence, or cause, of chronic immune activation is therefore hard to determine. In agreement with these observations, our data suggest that less differentiated TM T cells show increased signs of exhaustion in comparison with EM T cells, possibly due to the reverse actions of T-bet and Eomes promoting diverse effector functions in the differentiation machinery.

All of these individuals where however treated in chronic infection, and studies on patients initiating ART very early following infection would add valuable information on the dynamics of these responses. Future HIV vaccine or cure approaches most probably need to overcome this transcriptional barrier and induce sustained T-bet expression in order to clear virus infected cells.

Median and IQR are shown in all graphs and non-parametric Mann-Whitney tests were performed to compare differences between the groups. Median and IQR are provided for all bars and whiskers. Permutation test was performed to test for functional diversity between the groups pie charts.
