Researchers have discovered that neurons can both generate and burn their own fat as an energy source. In a rare brain disorder, a defective protein blocks this process, causing neurons to become fragile and impaired. By supplying specific fats, scientists were able to revive the cells’ energy production and restore their function within 48 hours—a finding that may open the door to new treatments for repairing the brain and reversing neurological damage.

The Hidden Protein Error Behind Failing Brain Energy

Researchers from the University of Queensland and the University of Helsinki have shown that neurons can tap into fat for energy, overturning the long-standing view that they depend solely on sugar. Remarkably, neurons can also generate their own fats by recycling components of the cell when extra fuel is needed. This entire process hinges on a key protein called DDHD2. Figure 1 shows A Fat-Powered Brain Breakthrough That May Restore Damaged Neurons.

Hereditary Spastic Paraplegia 54 (HSP54) is a rare neurological disorder caused by a malfunction in the DDHD2 protein. When this protein fails, neurons can no longer produce the fats required for energy and proper signaling, leading to early-onset and progressively worsening communication problems in the brain.

Children with HSP54 typically develop movement and cognitive difficulties early in life, but the new research offers promise. In lab experiments, scientists provided affected neurons with specific fatty acids, and within just 48 hours the cells restored their energy levels and began functioning more normally.

“This is a major breakthrough,” said Dr. Merja Joensuu, who initiated and led the study at the Australian Institute for Bioengineering and Nanotechnology [1]. “Our work shows that healthy neurons depend on fats for energy, and when this pathway breaks down in disorders like HSP54, we may be able to repair the damage and even reverse the neurological problems.”

Advancing Toward New Therapies

The researchers’ next goal is to test whether these fatty acid–based treatments are both safe and effective in pre-clinical models. These studies will determine if similar approaches could one day be tried in humans and whether this fat-powered energy pathway might help treat other neurological disorders that currently lack therapies. “We’re continuing this exciting collaboration with new non-invasive brain-imaging technologies to speed up the development of potential treatments. This breakthrough doesn’t just update our textbooks—it has the potential to change lives,” said Dr. Giuseppe Balistreri of the University of Helsinki.
