Successfully fighting infection requires a properly tuned immune system. Recent epidemiological studies link exposure to pollutants that bind the aryl hydrocarbon receptor (AHR) during development with poorer immune responses later in life. Yet, how devel- opmental triggering of AHR durably alters immune cell function remains unknown. Using a mouse model, we show that devel- opmental activation of AHR leads to long-lasting reduction in the response of CD8+ T cells during influenza virus infection, cells

critical for resolving primary infection. Combining genome-wide approaches, we demonstrate that developmental activation alters Downloaded from DNA methylation and expression patterns in isolated CD8+ T cells prior to and during infection. Altered transcriptional profiles in CD8+ T cells from developmentally exposed mice reflect changes in pathways involved in proliferation and immuno- regulation, with an overall pattern that bears hallmarks of T cell exhaustion. Developmental exposure also changed DNA methylation across the genome, but differences were most pronounced following infection, where we observed inverse correlation between promoter methylation and . This points to altered regulation of DNA methylation as one mechanism by

which AHR causes durable changes in T cell function. Discovering that distinct gene sets and pathways were differentially http://www.jimmunol.org/ changed in developmentally exposed mice prior to and after infection further reveals that the process of CD8+ T cell activation is rendered fundamentally different by early life AHR signaling. These findings reveal a novel role for AHR in the developing immune system: regulating DNA methylation and gene expression as T cells respond to infection later in life.

DNA enrichment is represented as the percentage of total input after subtracting the values of the relevant control Abs. For some experiments, reverse transcription quantitative PCR (RT-qPCR) and quantitative real-time PCR (qPCR) was performed as previously described (38), and primers for Dnmt1, Dnmt3a, Dnmt3b, and L13 were used (39, 40). For other experiments, gene expression on PND7 was examined. RNA was extracted from liver, reverse transcription was performed, and Cyp1a1 was measured by qPCR, with L13 used as a control (41). Data were an- alyzed using the DDCt method (42). MeDIP-seq and RNA-seq analysis MeDIP-seq reads were aligned to mouse reference genome (mm9) using Bowtie (version 0.12.7 parameter set -n 2 -k 1 -m 1) allowing up to two nucleotide mismatches to the reference genome and considering only uniquely mappable reads for downstream analyses (43). MeDIP-seq data were analyzed with MEDIPS package in R (44). For each sample, the aligned reads were extended in the sequencing direction to a length of 400 nucleotides. The short read coverage of the extended reads was calculated at genome-wide 50-bp bins. MeDIP-seq reads were counted in the gene bodies of RefSeq genes and differential methylation in gene bodies was assessed with edgeR package in R (45). To identify the DMRs throughout Downloaded from the genome we used various functions of MEDIPS package in R. Mean reads per million (RPM) values were calculated for genome-wide 500-bp nonoverlapping windows using MEDIPS.methylProfiling function. For any given 500-bp nonoverlapping window, mean RPM were calculated with statistically significant DMRs having a p value of ,0.001 and a ratio of ,0.5 (hypomethylated) or .2 (hypermethylated) using MEDIPS.select-

The DMRs identified for each comparison were annotated using CEAS. A Wilcoxon test was used to determine whether the differences between groups were statistically significant. For visualizing the methylation levels in the promoter (2 kb upstream to transcription start site [TSS]), gene body (TSS to transcription end site), and downstream (2 kb downstream to transcription end site) we used metagene representation. Each region was divided into 20 equal nonoverlapping windows and all genes were nor- malized for length and sequencing depth, and average methylation was plotted as a metagene.

A two-sample Kolmogorov–Smirnov test was used to determine whether the differences between groups were statistically significant. RNA-seq analysis was performed using Tuxedo programs with default parameters (47). Reads were aligned to the mouse reference genome (NCBI37, mm9) using TopHat (v1.4.1), then assembled into transcripts FIGURE 1.

In To identify pathways represented by these DEGs, IPA was contrast to uninfected mice, after infection, 428 DEGs were performed comparing Veh naive to TCDD naive groups and Veh identified between CD8+ T cells from TCDD infected compared infected to TCDD infected groups. Of the few genes altered in the with Veh infected offspring, with almost all (402 genes) exhibiting Veh naive/TCDD naive comparison, most were enriched in TNFR increased expression in adult offspring of TCDD-treated dams or other signaling pathways. Similar to DMRs, changes in gene (Fig. 3A, 3B, Supplemental Table I). Given that AHR is a tran- expression in CD8+ lymphocytes from adult animals that were scription factor, increased transcription in CD8+ T cells, and ul- developmentally exposed became considerably more evident after timately impaired function, could reflect persistent upregulation of infection.

However, interrogation of the RNA-seq TCDD infected versus Veh infected groups included cell cycle dataset does not support this idea.

Genes and pathways were not significantly differentially expressed in adult offspring of involved in immune responses to IAV were also differentially TCDD-treated dams, compared with adult offspring of control expressed (Fig. 3D).

Another key Downloaded from exposed mice neither prior to nor following infection. In contrast, finding is that pathways involved in epigenetic regulation and developmental AHR activation caused transient and significant DNA methylation were not altered in offspring of TCDD-treated increases in AHR target genes in neonates. For example, enhanced dams (regardless of infection). Although Wu et al.

Thus, T cells from developmentally exposed mice (Fig. 5A). To further AHR activation induced expression of target genes during the explore the idea that AHR may play a role in the regulation of DNMTs, we identified putative binding sites for AHR (AHR re- sponse elements [AHREs]) in the upstream regulatory regions and gene bodies of all three Dnmt genes (Fig. 5B). Using ChIP, we next investigated whether maternal exposure leads to binding of AHR to these putative AHREs. We were unable to detect alter- ations in binding of AHR to these genes in bone marrow cells, thymocytes, or CD8+ T cells from developmentally exposed mice by guest on September 28, 2021 (Fig. 5C–E). Thus, whereas developmental exposure altered DNA methylation across the genome and influenced expression of many other genes, we found no evidence that this was achieved through AHR persistently or directly altering Dnmt gene expression. Correlations between DMRs and gene expression were observed following infection DNA methylation influences transcriptional regulation in a context-specific manner, and recent work indicates a role of DNA methylation in gene bodies as well as promoters (18). To di- rectly examine correlations between DNA methylation and gene expression in these genomic locations, we integrated the MeDIP- seq and RNA-seq datasets. Consistent with other observations reported in the present study, differences in gene body methylation were more pronounced in CD8+ T cells from infected offspring. When comparing genes with differential gene body methylation in Veh infected and TCDD infected groups, we observed 1213 hypomethylated and 479 hypermethylated genes, with many in- volved in immune regulation, proliferation, transcription, and FIGURE 4.

SUPPLEMENTAL FIGURE 1. Quality control assessments of MeDIP-seq and RNA- seq are shown. (A) Following high-throughput sequencing, MeDIP-seq and RNA-seq reads were aligned to the mouse genome. (B) Correlation determination of gene body methylation of two independently generated samples for each treatment group is shown.

(C) Saturation analysis was performed using MeDIPs R package

MEDIPS.saturationAnalysis. (D) Sequence pattern coverage analysis was performed using the MEDIPS.coverageAnalysis function of MEDIPS R package.

SUPPLEMENTAL FIGURE 2. Overall DNA methylation of each chromosome is presented. Boxplot representations were used to quantitatively assess the methylation levels in purified CD8+ T cells from the Veh naïve (VN), TCDD naïve (TN), Veh Infected (VI) and TCDD infected (TI) groups. RPM values were plotted as boxplots using the boxplot function in R.

SUPPLEMENTAL FIGURE 3. DNA methylation across each chromosome in isolated CD8+ T cells from adult mice that were developmentally exposed to peanut oil vehicle (Veh) or TCDD is shown. Coverage density along the chromosomes was calculated, normalized to library size and plotted to visualize differences in methylation across different maternal exposure and infection of the adult offspring. Red = Veh naïve; Aquamarine = TCDD naïve; dark blue = Veh infected; green = TCDD infected.
