‘Hangry’ neurons might be a factor in pain persistence!
A recent paper caught my attention examining sensory neurons in the dorsal root ganglia (DRG) and their relationship with satellite glial cells (SGCs), which are part of the immune system. Historically, SGC–neuron interactions were viewed as pain promoting.
Xu et al. (2026) suggest something different. SGCs can actively suppress acute and chronic pain by transferring healthy mitochondria to DRG neurons.
This points toward mitochondrial dysfunction and cellular energy failure as contributors to pain persistence, not just nerve damage or inflammation. Which also raises a broader question about systemic mitochondrial health in chronic pain.
What’s the clinical implication?
Supporting cellular metabolism, neuroimmune communication and mitochondrial health may represent a foundational strategy in chronic pain care.
Even though this research is focused on details, it reinforces my understanding that pain is relational (between systems and parts), metabolic and a whole body issue.
