Chronic lung infection turns cells into senescent targets for potential drugs
A bacterium (Mycobacterium abscessus) that infects lung immune cells triggers those cells to enter senescence, a state where they stop dividing and trigger inflammation that helps the bacteria hide. A drug called Navitoclax killed these senescent cells and reduced bacterial burden in a model.
Why it matters: This research suggests blocking senescent cells could help treat chronic bacterial infections that resist standard antibiotics.
Keep in mind: This is a laboratory study in cells; human efficacy and safety of Navitoclax for this infection remain unknown.
