| Study Title | Metabolomics of Murine WT or MCJ KO CD19-BBz CD8 CAR-T cells rest in medium |
| Study Summary | MCJ/DnaJC15 is an endogenous negative regulator of Complex I and mitochondrial respiration. The goal of these experiments are to characterize the metabolic profile of murine WT or MCJ KO CD8 CD19-BBz CAR-T cells in cytokine-deprived condition. The CAR-T cells were expanded with IL-2 (60IU/ml) for 3 expansions (6 days) and rested in the medium for 48 hours. |

| Project Title: | Releasing the mitochondrial respiration brake MCJ/DnaJC15 enhances CD8 CAR-T cell therapy efficacy |
| Project Summary: | Metabolism of chimeric antigen receptor (CAR) T cells is emerging as an important area to improve CAR-T cell therapy in cancer treatment. Mitochondrial respiration is essential for survival and function of CAR-T cells, but developing strategies to specifically enhance mitochondrial respiration has been challenging. Here we identify MCJ/DnaJC15, an endogenous negative regulator of mitochondrial Complex I, as a metabolic target to enhance mitochondrial respiration in CD8 CAR-T cells. Loss of MCJ in CD8 CAR-T cells increases their in vitro and in vivo efficacy against mouse B cell leukemias. MCJ deficiency in TCR- specific CD8 cells also increases their efficacy against solid tumors in vivo. Furthermore, we reveal that human CD8 cells express MCJ and that silencing MCJ expression increases mitochondrial metabolism and anti-tumor activity of human CAR-T cells. Thus, targeting MCJ to enhance mitochondrial metabolism is a promising therapeutic strategy to improve the efficacy of adoptive T cell therapies. |

Collection:
| Collection ID: | CO003282 |
| Collection Summary: | Murine CD8 cells were isolated from lymph nodes and spleen using negative selection with CD8+ T cell isolation kit (for generation of CAR-T cells) (Miltenyi, order# 130-104-075) or positive selection (for OT-I CD8 cells) with CD8 (Ly-2) Microbeads (Miltenyi, order# 130-117-044). Mouse CD8 cells were activated with plate-bound anti-CD3 (5 g/ml) and soluble anti-CD28 mAbs (1 g/ml) for 48h for WT and cMCJ KO CD8 studies and OT-I CD8 cells studies. |

Treatment:
| Treatment ID: | TR003298 |
| Treatment Summary: | Metabolomics differences in this experiment are observed at baseline |
Sample Preparation:
| Sampleprep ID: | SP003296 |
| Sampleprep Summary: | CAR-T cells were isolated as described above either from in vitro culture or from bone marrow harvested in an in vivo study. The cells were washed in PBS and frozen at -80C until the assay is ready to run. Metabolites from cells were extracted at 2x106 cells/ml at 4°C (30 min) in the presence of 5:3:2 MeOH:MeCN:water (v/v/v). The samples were spun down and the resulting supernatant was transferred to new tubes and dried under a vacuum. The resulting residue was reconstituted in 0.1% formic acid at a 3x concentration, then analyzed on a Thermo Vanquish UHPLC coupled to a Thermo Q Exactive MS as previously described in detail. |
