How Mitochondria Organize Their Powerhouse Machinery for Optimal Performance
We are pleased to announce that Dr. Florent Waltz from the University of Basel, Switzerland, will be presenting at the Targeting Mitochondria 2025 congress in Berlin, Germany, on October 22-24, 2025.
Dr. Waltz will share insights from his groundbreaking research on "How Mitochondria Organize Their Powerhouse Machinery for Optimal Performance" with a special focus on photosynthetic organisms.
Key Highlights:
- In Situ Visualization: Researchers employed advanced imaging techniques to observe the mitochondrial respiratory chain within intact cells, providing a detailed view of its native architecture.
- Respiratory Supercomplexes: The study offers insights into how respiratory complexes assemble into supercomplexes, which are crucial for efficient electron transport and energy production in cells.
- Functional Implications: Understanding the organization of these supercomplexes sheds light on their role in cellular metabolism and energy conversion, potentially informing research into mitochondrial-related diseases.
Perspective:
- Challenging previous assumptions: The findings challenge long-standing models that assumed a more fluid, random distribution of respiratory chain components in mitochondrial membranes.
- Biological relevance: By analyzing structures in situ, this study underscores the importance of studying macromolecular organization in native cellular contexts, rather than relying only on purified proteins.
- Broader implications: These insights are critical not only for basic mitochondrial biology but also for understanding mitochondrial dysfunction in aging, neurodegenerative diseases, and metabolic disorders.
- New model for mitochondrial function: This study supports a model in which the geometrical and biochemical compartmentalization within cristae contributes significantly to the efficiency of oxidative phosphorylation.
These findings enhance our comprehension of mitochondrial function and may have implications for addressing metabolic disorders linked to mitochondrial dysfunction.

Development of Mitochondria-Based Therapeutic Strategies for Disease Treatment
We are pleased to announce that Prof. Kosuke Kusamori from Tokyo University of Science, Japan, will be presenting his pioneering research on "Development of Mitochondria-Based Therapeutic Strategies for Disease Treatment."
Summary
In recent years, the application of mitochondria isolated from cells for disease treatment has gained increasing attention, with their efficacy demonstrated in several diseases. However, the functions and characteristics of isolated mitochondria remain largely unknown, and their kinetics after administration into the body have yet to be fully elucidated.
Prof. Kusamori has been investigating the physical properties and in vivo kinetics of isolated mitochondria. In this talk, Prof. Kusamori will present his research on mitochondria-based therapeutic strategies aimed at advancing mitochondrial therapeutics.

Targeting Mitochondrial Pyruvate Carrier: Impact on Future Metabolic Therapies
Prof. Edmund Kunji from the University of Cambridge will give a major talk entitled Targeting mitochondrial pyruvate carrier: impact on future metabolic therapies, during the Targeting Mitochondria 2025 Congress, which will be held on October 22-24, in Berlin, Germany.
About Prof. Kunji's talk:
Fifty years after the mitochondrial pyruvate carrier (MPC) was first identified, researchers have now resolved its molecular structure and mechanism of action. In a landmark study published in Science Advances, Sichrovsky et al. (2025) unveiled how this critical mitochondrial complex mediates pyruvate transport and how its inhibition could be leveraged for therapeutic purposes in cancer, metabolic disorders, and more.
About his outstanding study:
Major Discoveries of the Study by Prof. Edmund Kunji and his teams
Molecular Structure of MPC:
The authors used cryo-electron microscopy to capture the architecture of the human MPC complex. They discovered that MPC forms a heterodimeric transport unit (MPC1/MPC2), creating a selective channel that guides pyruvate across the inner mitochondrial membrane.
Mechanism of Transport and Inhibition:
The study revealed how small-molecule inhibitors bind to the MPC complex and block its function, offering a blueprint for drug development. Structural analysis pinpointed specific binding sites that explain both transport dynamics and inhibition sensitivity.
Conserved Functionality:
Evolutionary conservation of the MPC mechanism across species (including yeast and human) underscores its universal biological role in cellular energy homeostasis.
Therapeutic Implications
Cancer:
Some tumors overexpress MPC to fuel high mitochondrial activity. MPC inhibitors could starve these cells of essential metabolites, selectively disrupting their growth.
Metabolic Diseases:
In conditions like non-alcoholic fatty liver disease (NAFLD), blocking MPC forces hepatocytes to burn fat instead of relying on glucose, leading to reduced liver fat accumulation.
Regenerative Medicine & Hair Growth:
MPC inhibition has been shown to stimulate lactate production, which may promote hair follicle cell activation, opening potential new treatments for alopecia.
Mitochondrial Dysfunction & Neurodegeneration:
Targeting MPC may allow modulation of energy metabolism in neurodegenerative and mitochondrial diseases, where ATP production and redox balance are impaired.
Broader Impact
Drug Development:
The structural elucidation of MPC provides a molecular framework for designing selective modulators, setting the stage for new classes of metabolic drugs.
Precision Medicine:
Understanding individual differences in MPC structure/function may lead to personalized metabolic therapies tailored to genetic or disease-specific metabolic profiles.
Synthetic Biology & Bioenergetics:
The detailed MPC model can inform the engineering of customized metabolic pathways, supporting advances in synthetic biology, cell therapies, and biotechnology.
Mitochondria & Organelle Crosstalk - Rethinking Organelle Crosstalk: Mitochondrial-Derived Vesicles in Peroxisome Biogenesis Presented by Dr. Ayumu Sugiura
At the heart of cellular metabolism, mitochondria and peroxisomes play tightly interconnected roles in lipid regulation, redox homeostasis, and energy dynamics. While direct contacts between these organelles have long been observed, the mechanisms underlying their communication and biological significance are only beginning to emerge.
In an insightful presentation, Dr. Ayumu Sugiura of Juntendo University, Japan, introduces a compelling hypothesis: mitochondrial-derived vesicles (MDVs) may serve as essential mediators in peroxisome biogenesis. These vesicles, generated by mitochondria in response to cellular cues, could carry lipids, enzymes, or signaling molecules critical for initiating or modulating peroxisomal function.
“Mitochondrial-derived vesicles may provide a missing mechanistic link in understanding how mitochondria influence peroxisome formation and specialization,” says Dr. Sugiura.
His talk emphasized that this vesicular communication is not a byproduct of stress or degradation but a targeted and regulated form of inter-organelle signaling, reflecting a deeper evolutionary connection.
Understanding MDVs and their role in peroxisome biology may open new avenues in treating metabolic disorders, neurodegenerative diseases, and inherited mitochondrial syndromes, where organelle cooperation is often impaired.
This new perspective encourages scientists to rethink organelle crosstalk not as static interactions but as dynamic exchanges of molecular information, and places MDVs at the center of this emerging dialogue.
