Age-related self-destruction of cells makes kidney prone to injury As advances in medicine allow individuals to live longer, people are facing unique age-related health challenges.

The discovery could eventually lead to new therapeutics for controlling chronic pain associated with trauma, diabetes, shingles, multiple sclerosis or other conditions that cause nerve damage
