Vanillin, a common flavoring agent used in e-liquids, has been studied for its potential effects on human kidney cells, specifically HK-2 epithelial cells. Research suggests that vanillin may influence cellular energy and autophagy pathways, which are vital for cell health and function.
Understanding these effects is important as flavored e-liquids are widely used, and their impact on organs beyond the lungs warrants further investigation to inform public health policies and consumer choices.
