Brain Cells Can Burn Fat to Fuel Activity

Triglycerides are an important fuel reserve for synapse function in the brain

Proper fuelling of the brain is critical to sustain cognitive function, but the role of fatty acid (FA) combustion in this process has been elusive. Here we show that acute block of a neuron-specific triglyceride lipase, DDHD2 (a genetic driver of complex hereditary spastic paraplegia), or of the mitochondrial lipid transporter CPT1 leads to rapid onset of torpor in adult male mice. These data indicate that in vivo neurons are probably constantl…

Brain cells can burn fat to fuel activity

While glucose, or sugar, is a well-known fuel for the brain, Weill Cornell Medicine researchers have demonstrated that electrical activity in synapses—the junctions between neurons where communication occurs—can lead to the use of lipid or fat droplets as an energy source.

Triglycerides may play an important role in brain metabolism

While glucose, or sugar, is a well-known fuel for the brain, Weill Cornell Medicine researchers have demonstrated that electrical activity in synapses—the junctions between neurons where communication occurs—can lead to the use of lipid or fat droplets as an energy source.

Brain Taps Lipid Stores for Energy During Activity

A groundbreaking study reveals that neurons can burn fat, challenging the long-held belief that the brain relies solely on glucose for fuel. Researchers discovered that when glucose is scarce, synaptic activity triggers neurons to break down lipid droplets and use the resulting fatty acids for energy.
