Current treatment options for chronic pain are often associated with dose-limiting toxicities, or lead to drug tolerance or addiction. Here, we describe a pain management strategy, based on cell-engineering principles and inspired by synthetic biology, consisting of microencapsulated human designer cells that produce huwentoxin-IV (a safe and potent analgesic peptide that selectively inhibits the pain-triggering voltage-gated sodium channel Na

OR1A1
rewired via an artificial G-protein deflector to induce the expression of a secretion-engineered and stabilized huwentoxin-IV variant. In a model of chronic inflammatory and neuropathic pain, mice bearing the designer cells showed reduced pain-associated behaviour on oral intake or inhalation-based intake of spearmint essential oil, and absence of cardiovascular, immunogenic and behavioural side effects. Our proof-of-principle findings indicate that therapies based on engineered cells can achieve robust, tunable and on-demand
analgesia
for the long-term management of chronic pain.
