Story summary

Research from the University of South Alabama links high-salt intake to faster blood vessel aging.
In mice, four weeks on a high-salt diet caused rapid deterioration in blood vessel function.
The immune system releases interleukin-16 (IL-16), driving premature aging of vessel cells.
Navitoclax cleared aged cells and restored vessel function in mice.
Translating these results to humans remains challenging, and safety evaluations of senolytic drugs are needed.
