宇宙飛行のストレス要因がミトコンドリア機能に与える影響と眼疾患発症リスク

Spaceflight stressors such as microgravity and radiation disrupt mitochondria in ocular tissues, leading to impaired energy production, oxidative stress, and reduced repair capacity. The anatomical distribution of mitochondria and disease localization presents an interesting relationship: cortical lens mitochondria align with the type of cataracts seen in spaceflight, while retinal mitochondria correspond to the pathology of SANS. These observations suggest mitochondrial damage may be more central to spaceflight-associated pathologies than previously recognized.
