Resveratrol at 100 μmol/L concentrations successfully eliminated Chlamydia psittaci bacteria from infected human bronchial cells by triggering autophagy-dependent apoptosis, achieved through suppression of the PI3K/AKT/mTOR pathway. The polyphenol upregulated key autophagy markers (LC3-II, Beclin-1) while increasing apoptotic proteins (Bax/Bcl-2 ratio, Cleaved Caspase-3), demonstrating a coordinated cellular response against intracellular pathogens. This mechanism represents a sophisticated therapeutic approach where resveratrol essentially hijacks the infected cell's machinery to eliminate both pathogen and host cell, preventing bacterial spread. The finding builds on resveratrol's established anti-aging properties by revealing another pathway through which it enhances cellular quality control. The mTOR suppression is particularly noteworthy, as this pathway is central to longevity research and metabolic health. However, the therapeutic window appears narrow—the same concentrations that kill bacteria also induce host cell death, raising questions about systemic applications. While promising for respiratory infections, translating these cellular effects to whole-organism benefits requires careful consideration of dosing and delivery methods to avoid widespread cellular toxicity.
