What this research studies

This work looks at why the nerve cells that drive the diaphragm (phrenic motor neurons) are lost or weakened with age. Researchers study how mitochondria (the cell's energy centers) and signals like BDNF/TrkB and TNFα change in these nerve cells using lab models and molecular techniques developed at Mayo Clinic. They will explore whether boosting protective pathways or blocking harmful inflammation (for example with compounds like quercetin or drugs like infliximab) helps preserve these breathing nerve cells. Results will be used to guide development of treatments to help older adults keep stronger breathing.

Who could benefit from this research

Good fit: Older adults with age-related breathing weakness or people at risk for respiratory decline from motor neuron loss (for example some patients with ALS) would be the most relevant candidates.

Not a fit: Younger people without age-related motor neuron loss or people whose breathing problems have non-neuromuscular causes may not directly benefit from this work.

Why it matters

Potential benefit: If successful, this work could lead to treatments that preserve breathing-related nerve cells and reduce respiratory problems in older adults.

How similar studies have performed: Prior lab studies support targeting BDNF signaling and mitochondrial health to protect neurons, but applying these approaches specifically to phrenic motor neurons in aging is fairly novel.
