FoxP3 Panel

FOXP3 Methylation Panel

Regulatory T-cells (Tregs) prevent autoimmune disease by inhibiting self-reactive T-cells. FOXP3 (forkhead box P3) is a transcription factor that is found in Tregs. It controls the expression of genes involved in regulating the immune system, making FOXP3 the master regulator that controls the development and function of Tregs. The methylation status of the FOXP3 gene can be used to measure the proportion of Tregs in a larger population of leukocytes. EpigenDx’s FOXP3 panel is a set of validated DNA methylation assays studying the methylation status of the FOXP3 gene and the regulation of genes (such as CTLA4 and CD25) important to Treg function.

Based on its 10+ years of technical expertise in epigenetics, EpigenDx has developed a custom FOXP3 gene methylation assay panel for the quantitative examination of the methylation status of the CpG dinucleotides in FOXP3 and associated genes. This epigenetic control panel covers genes such as FOXP3, CTLA4, IL2RA, IKZF2, IKZF4, and TNFRSF18 and 20+ methylation target regions, analyzing a total of 100+ CpG sites. Each assay is validated for PCR bias, sensitivity, and reproducibility. Using targeted Next-Gen bisulfite sequencing (tNGBS), EpigenDx increased the resolution of the assays, which allowed for the differentiation of small decreases in methylation and therefore, the identification of Treg cells, even in populations with a high methylation background such as peripheral blood monocyte cell (PBMC) samples.

The Relevance of FOXP3

CD4+ regulatory T cells (Tregs) are key mediators of immunological tolerance and promising effector cells to fight autoimmunity and chronic inflammation. Their therapeutic relevance is dependent on their functional stability, which has been linked to the demethylation of the TSDR/CNS2 enhancer site in the FOXP3 transcription factor of the Treg lineage.

Quantify DNA methylation levels in genes relevant to regulatory T-cell characterization and the FOXP3 transcriptional network. The human FOXP3 Panel analyzes up to 20 genes, 29 regions, and 141 CpG sites. The mouse Foxp3 panel covers up to 8 genes, 14 regions, and 125 CpG sites. The genes being analyzed include the regulatory regions of FOXP3, PDL1, CTLA4, IL2RA, RUNX1, IKZF2, IKZF4, and more.

Selected Genes of the FOXP3 Panel

Forkhead-box protein P3 (Foxp3) is a major transcription factor that is necessary for induction of the immunosuppressive function of regulatory T cells (Tregs). It is considered to be the most specific marker for Tregs in tumors, with its expression leading to poor survival rates in some types of cancer and improved survival rates in other types. Studies have shown that epigenetic modifications contribute to the stable expression of FOXP3 and other molecules associated with Treg cell function. These modifications include demethylation of CpG sites in the conserved non-coding sequence 2 (CNS2), Treg specific demethylated region (TSDR), proximal promoter, and upstream enhancer regions of the gene. Understanding the epigenetic regulation of FOXP3 and associated genes is critical in developing new approaches to autoimmune disease and cancer treatment.

CTLA4 is an inhibitory receptor protein found on the surface of FOXP3+ Tregs. The interaction between CTLA4 and receptors on antigen-presenting cells is known to turn off the immune response. While FOXP3 and CTLA4 are usually demethylated and expressed in Tregs, hypermethylation of the CTLA4 promoter has been found to result in dysfunctional FOXP3+ Tregs and autoimmune diseases such as rheumatoid arthritis. Assays covering SNPs in the gene have also been used to study the expression of CTLA4 in T-cells.

PD-1, or programmed cell death protein 1, is a receptor on T-cells that causes T-cell death or inhibition when bound with its ligand PDL1 (CD274), or programmed cell death ligand 1. High PDL1 expression has been associated with the reduction of conventional T-cell populations and the induction of FOXP3-expressing Tregs, downregulating the immune response. Thus, PD-1 and PD-L1 inhibitors are useful as cancer immunotherapy treatments.

EpigenDx has designed and validated DNA methylation assays covering the promoter region of PDL1.

Helios (IKZF2) and Eos (IKZF4) are two members of the Ikaros transcription factor family that are demethylated and expressed along with FOXP3 in Tregs. While Eos interacts directly with FOXP3 to silence certain genes (encoding T effector cytokines for instance), Helios binds to the FOXP3 promoter to upregulate FOXP3 expression. Both Eos and Helios are important biomarkers, essential for the proper function of CD4+ FOXP3+ Tregs. EpigenDx has designed and validated DNA methylation assays covering the intronic, non-coding regions of these two genes.

TNFRSF18, or GITR (glucocorticoid-induced TNF tumor-necrosis factor-related receptor), is another protein that is demethylated and expressed in high levels in Tregs and activated T cells. Because the engagement of GITR with anti-GITR antibodies can inhibit Treg function and deplete Treg population, drugs blocking GITR/TNFRSF18 have been proposed as cancer immunotherapy treatments and allergy medication.
