Observational StudyHighlightedHydrogen gas activates coenzyme Q10 to restore exhausted CD8+ T cells, especially PD-1+Tim3+terminal CD8+ T cells, leading to better nivolumab outcomes in patients with lung cancerMHID-7483719PMID: 329948212020Oncology LettersJunji Akagi, Hideo BabaAs previously reported, hydrogen gas improves the prognosis of patients with cancer by restoring exhausted CD8+ T cells into active CD8+ T cells, possibly by activating mitochondria. As mitochondrial activators exhibit synergistic effects with nivolumab, the current study investigated whether hydrogen gas also affects the clinical outcomes of nivolumab. A total of 42 of 56 patients with lung cance
Clinical TrialObservational StudyHighlightedHydrogen gas restores exhausted CD8+ T cells in patients with advanced colorectal cancer to improve prognosisMHID-0370162PMID: 305427402019Oncology ReportsJunji Akagi, Hideo BabaExhausted cluster of differentiation (CD)8+ T cells lose immunological activity due to mitochondrial dysfunction caused by peroxisome proliferator‑activated receptor γ coactivator 1α (PGC‑1α) inactivation, resulting in a poor prognosis in patients with cancer. As hydrogen gas was recently reported to activate PGC‑1α, the present study investigated whether it restores exhausted CD8+ T cells to impr
