| Study Title | Autoimmune Disease Risk Gene ANKRD55 Promotes T Cell Proliferation and Th17 2 Effector Function Through Metabolic Modulation |
| Study Type | TH17 Cell cultures |
| Study Summary | ANKRD55, a gene linked to various autoimmune diseases through Genome-wide association studies (GWAS), plays a critical role in T cell function and inflammation. This study shows that Ankrd55-deficient mice are protected from T cell-mediated colitis but more vulnerable to Citrobacter rodentium infection, due to impaired CD4⁺ T cell proliferation and reduced TH17 cytokine production. To define the alterations in cellular metabolism caused by a Ankrd55-/- mutation in TH17 cells, we applied four metabolic profiling methods to in vitro differentiated TH17 cells. We found nucleotides were elevated in Ankrd55-/- compared to WT TH17 cells, with one-carbon units’ provider-folate (10-formyl-THF) being enriched. This was in accordance with the upregulated expression of enzymes in the SGOC pathway observed in Ankrd55-/- cells. |

| Project Title: | Metabolite profiling of Ankrd55-/- TH17 Cells |
| Project Summary: | Genome-wide association studies (GWAS) have linked the locus encoding Ankyrin Repeat Domain 55 (ANKRD55) with numerous autoimmune diseases; however, its biological function and role in inflammation are unclear. Here, we demonstrate that Ankrd55-deficient mice are protected from T cell-mediated colitis but are more susceptible to Citrobacter rodentium infection. Mechanistically, Ankrd55 deletion impairs CD4+ T cell proliferation and reduces effector cytokine production in T helper 17 (TH17) cells in a cell-intrinsic manner. ANKRD55 is associated with mitochondria, and its loss is associated with impaired mitochondrial respiration and activation of the LKB1 pathway. Consistently, IL-17 production can be rescued by the deletion of LKB1 in Ankrd55-deficient T cells. Altogether, our study implicates the protein ANKRD55 as a functional modulator of T cell metabolism that directly impacts TH17 responses, highlighting it as a potential target across multiple autoimmune diseases. |

| Collection ID: | CO004232 |
| Collection Summary: | Three biological replicates were generated for each WT and Ankrd55-/- cell lines. Naïve CD4+ T cells from either wild-type or Ankrd55-/- C57BL/6 animals were isolated by using EasySep Mouse Naïve CD4+ T Cell isolation Kit (STEMCELL technologies, Vancouver Canada) and 1 million/mL of cells was cultured in 2 μg/mL anti-CD3/anti-CD28-coated 96-well plates under different cytokine conditions for 3 days. Cells were harvested on day 3 and pellets were snap-frozen and preserved at -80C until extraction. A polar extract was prepared using 1,800,000 cells extracted in 80% methanol, while a lipid extract was obtained from 600,000 cells using 100% isopropanol. The cleared extracts were analyzed with a combination of four previously described liquid chromatography high-resolution mass spectrometry (LC-MS) methods. The polar methanol extract was analyzed using the HILIC-pos (10 μL), HILIC-neg (30 μL), and C18-neg (30 μL) methods, which target polar metabolites and those of intermediate polarity. In contrast, the isopropanol extract was profiled using the C8-pos lipid profiling method. |
