Transplantation of encapsulated mitochondria alleviates dysfunction in mitochondrial and Parkinson's disease models.

Cell2026 Mar 18

Mitochondrial transplantation holds significant potential for the treatment of mitochondrial diseases. However, how to efficiently deliver exogenous mitochondria to somatic cells or tissues remains unresolved. We present a mitochondrial transplantation approach to deliver mitochondria into the cells and tissues of mice and monkeys with high efficiency, based on encapsulating mitochondria with vesicles derived from the plasma membrane of erythrocytes. Treatment with encapsulated mitochondria complemented the loss, deletion, or mutation of mitochondrial DNA, thereby rescuing the associated bioenergetic and biochemical defects in patient-derived cells with mitochondrial disorders. Furthermore, mitochondrial capsules rescued the mitochondrial DNA depletion syndrome and Leigh syndrome in Dguok-/- and Ndufs4-/- mouse models, respectively. Moreover, in a mouse model of Parkinson's disease, mitochondrial capsules rescued neuron loss, improved motor skills, and restored mitochondrial function in the affected brain regions. Our study demonstrates the potential of this mitochondrial capsule as a treatment for mitochondrial disorders and proposes an "organelle therapy" strategy in regenerative medicine.

COG5 deficiency disrupts cellular copper homeostasis and underlies the impaired mitochondrial OXPHOS function.

PLoS genetics2026 Mar

COG5, a subunit of the conserved oligomeric Golgi (COG) complex, plays a critical role in retrograde trafficking within the Golgi apparatus. Dysfunction of COG5 is associated with various human disorders, yet the underlying pathogenic mechanisms remain poorly understood. To investigate the mechanisms, we conducted proteomic analyses using COG5-deficient and rescue cell models, which revealed a potential link between COG5 dysfunction and mitochondrial oxidative phosphorylation (OXPHOS) deficiency. Using COG5-deficient cell models and patient-derived cells harboring COG5 variants, we biochemically validated the involvement of COG5 in mitochondrial OXPHOS, particularly in the regulation of complex I content. These models also exhibited elevated cellular copper levels. Notably, the significant reduction in OXPHOS complexes could be rescued by either restoring COG5 expression or administering a copper chelator. We further demonstrated that excessive cellular copper disrupts the function of mitochondrial iron-sulfur clusters, potentially leading to complex I assembly defects. Additionally, we identified a patient with biallelic COG5 variants presenting with a distinct subtype of mitochondrial disease (Leigh syndrome), a phenotype not previously associated with COG5-related disorders. These findings provide novel mechanistic insights into the role of COG5, extending beyond its established function in Golgi-mediated glycosylation modifications. Our results underscore the importance of COG5 in mitochondrial function through a copper-dependent pathway, offering new perspectives on its contribution to cellular homeostasis and disease pathogenesis.

Acute Neurological Complications After Transplantation in Methylmalonic Acidemia: A 35-Patient French Cohort.

Journal of inherited metabolic disease2026 Mar

Transplantation is an effective therapeutic option to improve quality of life in patients with severe methylmalonic acidemia (MMA). However, data regarding neurological complications following transplantation remain limited. A retrospective, single-center study was conducted at Necker Hospital (France), including MMA patients who underwent kidney (KT), liver (LT), or liver-kidney transplantation (LKT) between 2007 and 2022. Our aim was to evaluate acute neurological complications occurring after transplantation, focusing on clinical features, laboratory parameters and neuroimaging. Sensorineural complications were also assessed. Thirty-five patients were included, 21 had undergone LKT, 10 LT and 4 KT. The median age at transplantation was 10.1 years, with a median follow-up of 5 years. Tacrolimus was used in 91% of patients. Acute neurological complications likely related to MMA occurred in 17% of patients. They include Leigh syndrome with identifiable triggers, observed in 4 patients (2 early and 2 late-post-transplantation), leading to one early- and one late-onset death. Stroke-like episodes occurred in 2 patients. Non-epileptic myoclonus, likely related to calcineurin inhibitor (CNI), were reported in 31% of patients. Pre-transplant brain MRI showed nonspecific abnormalities in 31% of patients and remained stable afterwards. Post-transplant ophthalmological data available for 17 patients showed 3 optic atrophies. No acute vision or hearing loss was reported. Although transplantation improves metabolic control in MMA, acute neurological complications can still occur following a triggering event, even years after transplantation. The risk may arise from sensitivity to CNI-induced neurotoxicity. Pre- and post-transplant neuroimaging, emergency metabolic protocols, and tailored immunosuppression are essential for long-term management.

Pluripotent stem-cell-based screening uncovers sildenafil as a mitochondrial disease therapy.

Cell2026 Mar 19

Mitochondrial disease encompasses inherited disorders affecting mitochondrial function. A severe and untreatable form of mitochondrial disease is Leigh syndrome (LS), causing psychomotor regression and metabolic crises. To accelerate drug discovery for LS, we screen a library of 5,632 repurposable compounds in neural cells from LS-patient-derived induced pluripotent stem cells (iPSCs). We identify phosphodiesterase type 5 (PDE5) inhibitors as leads and prioritize sildenafil for its clinical safety. Sildenafil corrects mitochondrial membrane potential defects, restores neurodevelopmental pathways, and normalizes calcium responses in LS brain organoids. In small and large mammalian models of LS, sildenafil extends lifespan and ameliorates disease phenotypes. Off-label treatment on an individual basis with sildenafil in six LS patients improves their motor function and resistance to metabolic crises. Collectively, the findings highlight the potential of iPSC-driven drug discovery and position sildenafil as a promising drug candidate for mitochondrial disease.

[Decreased plasma citrulline is a biochemical marker in newborn screening for MT-ATP6-associated mitochondrial disease: two case reports and a literature review].

Zhongguo dang dai er ke za zhi = Chinese journal of contemporary pediatrics2026 Feb 15

This report describes the potential diagnostic value of decreased plasma citrulline (pCit) levels for the early recognition of MT-ATP6-related mitochondrial disease. Two cases were reported, and relevant literature was reviewed. Case 1: Onset occurred at 3 months of age with an acute presentation that rapidly progressed to metabolic crisis, multiorgan failure, and central respiratory failure, resulting in death in early infancy. Case 2: Onset occurred at 6 months of age with progressive developmental delay. Brain magnetic resonance imaging revealed bilateral symmetric basal ganglia lesions, and Leigh syndrome was diagnosed. Following citrulline supplementation and comprehensive intervention, improvements were observed in intellectual development and metabolic indices. Both patients carried the MT-ATP6 variant m.8993T>G (p.L156R), confirming MT-ATP6-associated mitochondrial disease. This case series indicates that decreased pCit on newborn screening is an early biochemical marker of MT-ATP6-associated mitochondrial disease. Early diagnosis and metabolic intervention are beneficial for prognosis. 该文报道血浆瓜氨酸(plasma citrulline, pCit)浓度降低对于MT⁃ATP6基因相关线粒体病早期识别的价值。病例1,3月龄急性起病,迅速进展为代谢危象、多器官功能衰竭及中枢性呼吸衰竭而夭折。病例2,6月龄发病,逐步出现发育落后,影像学显示双侧基底节对称性病变,诊断为Leigh综合征,在补充瓜氨酸及综合干预后,智能发育和代谢指标均得到改善。2例患儿均存在MT⁃ATP6基因m.8993T>G(p.L156R)变异,确诊为MT⁃ATP6基因相关线粒体病。该病例系列提示,新生儿疾病筛查pCit浓度降低应警惕线粒体MT⁃ATP6基因相关线粒体病可能,早期诊断和代谢干预有利于改善预后。.
