This research identifies a specific biological pathway, the PIEZO1-SLC7A11-glutamate axis, as the primary driver of chronic bladder pain and urinary dysfunction following recurrent infections. The study reveals that the inflammatory cytokine IL-6 causes an overabundance of the mechanosensitive ion channel PIEZO1 in the bladder lining, which leads to excessive oxidative stress during physical movement or stretching. To counter this stress, cells activate the antioxidant transporter SLC7A11, which unintentionally triggers a massive release of glutamate into the surrounding tissue. This chemical…
